  Citation × Citation Citation Abstract Copy Title: Historical Reconstruction of Oregon’s Commercial Fisheries Landings Information Reports number 2014-02 Abstract -- Historical catch information is essential for fisheries stock assessment. Without knowing the catch history it is difficult to understand how a stock responds to exploitation (Hilborn and Walters 2003). On the West Coast of the United States, fisheries are managed by the Pacific Fishery Management Council (PFMC). Stock assessments for the groundfish species under the PFMC’s purview are conducted every other year. Recent catch data (from 1981 on) for these assessments are available from the Pacific Fisheries Information Network (PacFIN), a regional fisheries database that manages fishery-dependent information in cooperation with National Marine Fisheries Service (NMFS) and West Coast state agencies. Prior to 1981, however, catch information is sparse, and there is no database analogous to PacFIN to handle the data. Historical reconstruction of catches prior to 1981 has been conducted by assessment authors for each assessment individually, and authors have often approached the problem differently, using different data sources and a variety of methods. The PFMC recommended undertaking a coordinated reconstruction of West Coast groundfish landings to provide a comprehensive species-specific time series for use in stock assessments. The intent of this coordinated reconstruction is to improve the reliability of historical landings by identifying and drawing on preferred data sources, as well as applying a standardized method across all species. This should reduce duplication of effort and use of inconsistent assumptions by assessment authors in reconstructing catch, and expedite development and review of stock assessments in the future. This document outlines the methodology we developed in a joint effort of the Oregon Department of Fish and Wildlife (ODFW) and the NMFS Northwest Fisheries Science Center (NWFSC) to reconstruct historical catches of species commercially landed in Oregon. The original goal was to focus on historical landings of groundfish alone; however the effort was expanded to include all species harvested commercially. The list of these species is provided in Table A1, Appendix A. We also revised species specific landings made within multi-species market categories during the first six years of the PacFIN era (1981-1986). Reconstruction of the historical landings included several steps, in which we: 1) Determined the annual landings made within each market category, by gear; 2) Derived species compositions for each multi-species market category by gear, year and spatial stratum (where available); 3) Applied the year specific species compositions (from Step 2) to the historical landings in each multi-species market category (from Step 1) to obtain a species-specific time series of landings; 4) Summed the species-specific landings across market categories by gear to obtain a final time series of landings for individual species in Oregon. This report is associated with a data file, called Oregon_commercial_landings_1889-1986_v1.0.xls (OCL), which is available from ODFW and NWFSC. The landings are reported in round pounds, which represent the whole–fish weight of the landed catch. Where historically landings were reported as dressed weights, those weights were converted to round pounds prior to incorporation into the file. The reconstruction does not include estimates of recreational catches, foreign fleet landings, or discard associated with commercial harvest. We focused on the reconstruction of catch landed in Oregon. Fish landed in Oregon, however, are not necessarily caught in state waters. Oregon vessels, particularly those from northern ports, such as Astoria/Warrenton, frequently fish in waters off of Washington, but return to Oregon to land their fish.

  Citation × Citation Citation Abstract Copy Title: Oregon's Coastal Chinook, A Summary Abstract -- Whether they are landed by anglers using rods and reels, or commercial fishermen using troll gear, chinook salmon are prize fish. These fish have been an important cultural and economic element of Oregon's coastal economy for more than 100 years. Although human activity has affected the species during the past century, chinook remain today a strong and extremely valuable component within the state economic system. In 1987, for example, commercial and recreational fisheries caught more than a half-million chinook. Most of those fish had their origin in coastal streams of Oregon and northern California. This report summarizes the findings of a study that offers a comprehensive view of Oregon's coastal chinook salmon populations based on the best information currently available. The study is titled "Chinook Salmon Populations in Oregon Coastal River Basins: Description of Life Histories and Assessment of Recent Trends in Run Strengths." The study does not deal with chinook stocks of the Columbia River Basin. A limited supply of document copies is available for public review at libraries and department offices around the state. Personal copies of the study are available for a fee.

  Citation × Citation Citation Abstract Copy Title: Abundance, Life History, and Distribution of Bull Trout in the Hood River Basin: A Summary of Findings from 2006 to 2009 Information Reports number 2010-01 Abstract -- Bull trout have been adversely affected by many land, water, and fisheries management activities throughout the range of the species. Degraded and fragmented habitat and negative interactions with nonnative fishes have led to a decline in bull trout distribution and abundance, several local extirpations, and a federal listing in 1998 as a threatened species under the Endangered Species Act (USFWS 2002). Distribution and abundance of bull trout also have declined in Oregon, and most management units in the state are considered to be threatened by conservation risks (ODFW 2005). One of these at-risk management units exists in the Hood River basin (ODFW 2005). Bull trout in Hood River basin currently are thought to exist as two independent reproductive units (USFWS 2002), known as local populations (Rieman and McIntyre 1995). The Clear Branch local population was isolated from the rest of the basin by the construction of Clear Branch Dam in 1968. This dam provides limited downstream fish passage during periods of spill and no voluntary upstream passage. Bull trout in this population inhabit Laurance Lake reservoir and the tributaries Pinnacle Creek and upper Clear Branch, which flow into the reservoir. The Hood River local population is distributed in the mainstem Hood River, Middle Fork Hood River (Middle Fork), and a few Middle Fork tributaries. Fluvial migrants from Hood River basin also forage and winter in the Columbia River (Pribyl et al. 1996, Buchanan et al. 1997). Bull trout have been observed in the East and West Fork basins of the Hood River, but these sightings have been rare. Presently, there is little evidence to suggest local populations exist in these tributary basins (USFWS 2002, Reagan and Olsen 2008). The status of both local populations is extremely precarious. Threats that put the Clear Branch population at risk of extirpation include low abundance, negative interactions with illegally introduced smallmouth bass, isolation from upstream migration and immigration, and diminished spawning and rearing habitat (USFW 1998). The Hood River population also appears to be small and is affected by passage barriers, unscreened irrigation diversions, impaired water quality, and periodic debris flows during glacial outbursts (USFWS 1998). As mandated by their federally designated threatened status, recovery plans were drafted by the US Fish and Wildlife Service (USFWS) for each distinct population segment, including for Hood River bull trout in 2002. This draft plan listed four goals for recovery in this basin: 1) establish at least one more local population in addition to the two existing populations, 2) increase the estimated adult population in the basin to at least 500 individuals, 3) achieve a stable or increasing trend at the population recovery level for at least two generations (=10 years), and 4) improve habitat connectivity by addressing problems with passage and screening at diversions and seasonal water quality barriers (USFWS 2002). The recovery plan also sets out research and monitoring needs critical to the recovery of these populations. Needed are accurate adult abundance estimates; a standardized monitoring program; more life history information for each local population, including how Hood River bull trout use of the Columbia River and the effects of potential passage obstructions on movement; and more information on the threat posed to the Clear Branch population by the illegal introduction of smallmouth bass in Lake Laurance reservoir. The Oregon Department of Fish and Wildlife (ODFW), with the help of the USDA Forest Service (USFS), initiated a four-year study in 2006 seeking to address these needs by synthesizing available data and conducting further studies to improve our understanding of the abundance, life history, and potential limiting factors of bull trout in the Hood River recovery unit. This report describes our findings, summarizes previous studies in the context of new information, and recommends a standardized monitoring protocol and future research. Our specific study objectives were as follows: 1. Assess adult abundance of the Clear Branch local population and develop a monitoring protocol to track abundance trends that is statistically reliable, cost-effective, and that minimizes potential adverse effects on this small isolated population. 2. Describe the juvenile and adult life history patterns of the Clear Branch local population. 3. Assess the potential impact of smallmouth bass on bull trout in Laurance Lake reservoir. 4. Determine current distribution of bull trout reproduction and early rearing in potential bull trout streams in the Hood River basin. 5. Describe the migratory life history of Hood River bull trout and assess the potential impacts of Coe Diversion and two new falls on the Middle Fork Hood River (scoured by the November 2006 glacial outburst) on bull trout migrations.

  Citation × Citation Citation Abstract Copy Title: 2009 Foskett Spring Speckled Dace Investigations Progress Report 2009 Abstract -- Speckled dace (Rhinichthys osculus) are geographically widespread throughout the western United States and occur in many isolated subbasins and interior drainages in south-central Oregon. The Foskett Spring speckled dace (R. osculus ssp.) is represented by a single population that inhabits Foskett Spring (Figure 1) on the west side of Coleman Lake (Warner Lakes subbasin) in Lake County, Oregon. Foskett speckled dace was listed as threatened under the federal Endangered Species Act in 1985 (U.S. Fish and Wildlife Service 1985). The Foskett speckled dace became isolated in Foskett Spring at the end of the Pluvial period (~9,000-10,000 years ago). Foskett Spring is a natural spring that rises from a springhead pool, flows through a narrow spring brook into a series of shallow marshes, and then disappears into the soil of the normally dry Coleman Lake (Figure 1). A second population in Dace Spring, located approximately 0.8 kilometer south of Foskett Spring, was established from an introduction of 100 fish from Foskett Spring in 1979-1980 (Williams et al. 1990); however recent surveys have failed to document their continued existence at this location. In 1987, the U.S. Bureau of Land Management (BLM) acquired, through exchange, the 65 hectare parcel of land containing Foskett and Dace Springs. Both sites were fenced to exclude livestock. The Recovery Plan for the threatened and rare native fishes of the Warner Basin and Alkali Subbasin states that Foskett speckled dace will probably not be delisted in the near future because of its extremely isolated range and potential for degradation of its habitat from localized events (USFWS 1997). The primary recovery objective for this species is long-term persistence through preservation of its native ecosystem. The plan further states that the conservation and long term sustainability of this species will be met when: 1) long-term protection of its habitat, including spring source aquifers, springpools and outflow channels, and surrounding lands is assured; 2) long-term habitat management guidelines are developed and implemented to ensure the continued persistence of important habitat features and guidelines include monitoring of current habitat and investigation for and evaluation of new spring habitats; and 3) research into life-history, genetics, population trends, habitat use and preference, and other important parameters is conducted to assist in further developing or refining criteria 1) and 2), above. Actions needed to meet these criteria include protecting the fish population and its habitat, conserving genetic diversity of the fish population, ensuring adequate water supplies are available, monitoring of the dace population and habitat conditions, and evaluating long-term effects of climatic trends on recovery of this fish population. The purpose of this investigation was to determine the status of the federally listed Foskett Spring speckled dace and its habitat. This report updates a monitoring program initiated in 2005 by ODFW (Scheerer and Jacobs 2005) by providing results of monitoring conducted in 2009. Specifically, this monitoring program calls for biannual estimates of population abundance, assessments of distribution and demographic parameters and assessments of physical habitat conditions.

SAFE reports are intended to summarize the best available scientific information concerning the past, present, and possible future condition of the stocks, marine ecosystems, and fisheries being managed under federal regulation. Regional Fishery Management Councils use this information to determine annual harvest levels for each stock; document significant trends or changes in the resources, marine ecosystems, and fishery over time; and assess the relative success of existing state and federal fishery management programs. This is the eight Status of the Pacific Coast Coastal Pelagic Species Fishery SAFE document prepared for the Pacific Fishery Management Council (Council). Following NMFS guidelines, the purpose of this report is to briefly summarize aspects of the coastal pelagic species (CPS) FMP and to describe the history of the fishery and its management. Species managed under this FMP include: Pacific sardine (Sardinops sagax), Pacific mackerel (Scomber japonicus), northern anchovy (Engraulis mordax), jack mackerel (Trachurus symmetricus), and market squid (Loligo opalescens). The SAFE report for Pacific Coast CPS fisheries was developed by the Council’s Coastal Pelagic Species Management Team (CPSMT) from information contributed by scientists at NMFS, Southwest Fisheries Science Center (SWFSC), California Department of Fish and Game (CDFG), Oregon Department of Fish and Wildlife (ODFW), and Washington Department of Fish and Wildlife (WDFW). Included in this report are descriptions of landings, fishing patterns, estimates of the status of stocks (including stock assessments for Pacific sardine and Pacific mackerel, Appendix 1 and Appendix 2), and acceptable biological catches (ABCs). The ABC recommendations, together with social and economic factors, are considered by the Council in determining annual harvest guidelines and other measures for actively managed fisheries (i.e., Pacific mackerel and Pacific sardine).

  Citation × Citation Citation Abstract Copy Title: Neacoxie Watershed Abstract -- Previously, little information was known about the ecology or the condition of native habitats in the Neacoxie sub-watershed that drains from the city of Warrenton into the north section of the Necanicum Estuary in the city of Seaside. In 2002, the Necanicum Watershed Council completed an assessment for the Necanicum River watershed, but with major knowledge gaps for the Neacoxie watershed, which includes the Neacoxie Creek corridor and the Clatsop Plains. In order for the North Coast Land Conservancy (NCLC) and other land managers to develop stewardship priorities and to make informed decisions about land management actions in this region, additional information was required. Together with the Necanicum Watershed Council and the North Coast Watershed Association, NCLC secured funding to conduct habitat inventories of the Neacoxie watershed. The Neacoxie Watershed Assessment summarizes the results of terrestrial plant transects and aquatic plant surveys completed in the summer of 2011 on ten properties owned by the North Coast Land Conservancy (NCLC) in the Neacoxie Creek watershed (please refer to Appendices A & B). Habitat types include stabilized sand dunes dominated by coastal prairie habitat, interdunal wetland swales and lakes, upland Sitka spruce forest, and forested wetlands. Percent composition of each plant community type observed was calculated. Invasive non-native plant species were recorded. Surveys were also conducted for both native and non-native plants in four water bodies owned by NCLC or adjacent to land trust properties. The plant community data that were collected will be used to evaluate baseline ecological conditions in the Neacoxie watershed. Plant communities can be used as indicators of long-term tidal and hydrologic conditions as well as the ecological health of the landscape. Repeated measurements can be used to assess community changes over time and to assess how plant community composition compares to that described for natural conditions. This information will assist the land trust in making science-based stewardship decisions on its properties, and can be used by other landowners to better understand changes occurring in plant communities in similar habitats on their properties as a result of human disturbance (e.g., land development, farming, grazing) and invasion by non-native plants.

Oncorhynchus mykiss exhibit a complex of life-history strategies ranging from residency in small headwater streams to anadromy involving migrations of hundreds of kilometers. In the Grande Ronde River basin of Northeast Oregon, both resident and anadromous life-history forms coexist, and thus populations found there likely exhibit partial migration. Partial migration may have important consequences for “anadromous” species listed under the Endangered Species Act (ESA). The recent decline of summer steelhead (Oncorhynchus mykiss) stocks in the lower Snake River has prompted their listing under the ESA. Declines in steelhead are potentially due to elevated mortality rates associated with anadromous migrations. If resident and anadromous life-history characteristics result from a phenotypically plastic trait (i.e. a genetic trait that is highly variable due to influences from environmental factors), then elevated mortality associated with the anadromous type may be shifting the populations towards residency. Further, although the anadromous expression of the trait may be declining, the trait would not necessarily be lost. Identification of the plasticity of these traits would then be important for the management of these stocks. We investigated life history traits of O. mykiss with studies in both the hatchery and natural environment. We anticipated that these complimentary approaches would allow us to evaluate the relationship between the two life-history forms. They should further allow us to explore the feasibility of using hatcheries to produce anadromous progeny from resident parents if the number of anadromous life-history forms becomes severely depressed.

Title: AI - Stream Habitat Conditions on Industrial Forest Lands in Coastal Oregon Abstract -- In the summer of 1998 and 1999, watersheds in western Oregon were randomly sampled for stream habitat conditions.

Productive utilization of these remarkable habitat types is critical for the recovery and sustainability of Oregon Coastal coho. Specifically, this project developed, and adapted innovative mark recapture techniques using PIT tags to monitor the coho life cycle, further evaluated over-winter rearing strategies in relation to temporal and spatial habitat use and continued project effectiveness monitoring in these study streams. In addition, coho diet analyses were designed and conducted and will be analyzed in relation to seasonal and diurnal variations in environmental factors in order to assess proximal causes of habitat productivity.

From 1991 through 2003, approximately 5400 metric tons of widow rockfish (from all catch areas) were landed into Oregon by shore-based midwater trawlers. The Oregon Department of Fish and Wildlife sampled widow rockfish, sablefish (Anoplopoma fimbria) and other groundfish caught at Cobb Seamount during this time period, in addition to conducting routine sampling of commercial landings from areas closer to shore. Data were collected on length, age, sex, and reproductive maturity of the Cobb Seamount fish. The objectives of this study were to describe the developing fishery for widow rockfish at Cobb Seamount, and to attempt to identify biological differences between widow rockfish from Cobb Seamount and those found closer to shore. It was hoped that such differences could be used to facilitate shoreside enforcement of different fishing regulations for each area. Data collected from landings during the 1991-2003 time period suggest that compared to widow rockfish caught within 200 miles of shore (inside the U.S. Exclusive Economic Zone), the Cobb Seamount population had a smaller average overall size, and a smaller average female size-at-maturity.

  Citation × Citation Citation Abstract Copy Title: 2009 Borax Lake Chub Investigations Progress Reports 2009 Abstract -- The Borax Lake chub (Gila boraxobius) is a small minnow endemic to Borax Lake and adjacent wetlands in the Alvord Basin in Harney County, Oregon (Williams and Bond 1980). Borax Lake chub are represented by a single population that inhabits a 4.1 hectare geothermally-heated alkaline lake. Borax Lake is a natural lake perched 10 meters above the desert floor on sinter deposits, which is fed almost exclusively by thermal groundwater. The Borax Lake chub was listed as endangered under the federal Endangered Species Act in 1982 (U.S. Fish and Wildlife Service 1982). Population abundance estimates obtained since 1991 indicate a fluctuating population ranging between approximately 4,000 and 34,000 fish (Salzer 1997; Scheerer and Jacobs 2008). The basis for the Borax Lake chub’s listed status was not population size, but the security of a very limited, unique, isolated, and vulnerable habitat. Because Borax Lake is situated above salt deposits on the desert floor, alteration of the salt crust shoreline could reduce lake levels and the habitat quantity and quality available to Borax Lake chub. At the time of the listing, Borax Lake was threatened by habitat alteration caused by geothermal energy development and alteration of the lake shore crust to provide irrigation to surrounding pasture lands. The Borax Lake chub federal recovery plan, completed in 1987, advocated protection of the lake ecosystem through the acquisition of key private lands, protection of groundwater and surface waters, controls on access, and the removal of livestock grazing (U.S. Fish and Wildlife Service 1987). Recovery measures implemented since listing have improved the conservation status of Borax Lake chub and protection of its habitat (Williams and Macdonald 2003). When the species was listed, critical habitat was designated on 259 hectares of land surrounding the lake, including 129 hectares of public lands and two 65-hectare parcels of private land. In 1983, the U.S. Bureau of Land Management designated the public land as an Area of Critical Environmental Concern. The Nature Conservancy began leasing the private lands in 1983 and purchased them in 1993, bringing the entire critical habitat into public or conservation ownership. The Nature Conservancy ended water diversion from the lake for irrigation and livestock grazing within the critical habitat. Passage of the Steens Mountain Cooperative Management and Protection Act of 2000 removed the public BLM lands from mineral and geothermal development within a majority of the basin. These actions, combined with detailed studies of the chub and their habitat, have added substantially to our knowledge of the Borax Lake ecosystem (Scoppettone et al. 1995, Salzer 1992, Perkins et al. 1996). However, three primary threats remain. These include the threat to the fragile lake shoreline, wetlands, and soils from a recent increase in recreational use around the lake (particularly off-road vehicle usage), the threat of introduction of nonnative species, and potential negative impacts to the aquifer from geothermal groundwater withdrawal if groundwater pumping were to occur on private lands outside the protected areas (Williams and Macdonald 2003). A review of the conservation status of the Borax Lake chub by Williams and Macdonald (2003) cited the lack of recent and ongoing population and ecosystem monitoring as one argument against downlisting or delisting the species at that time. Although an increase in abundance is not a goal in the successful recovery of this species, monitoring trends in abundance over time is an important management tool to assess species status. The objectives of this study were to: 1) obtain a mark-recapture population estimate of Borax Lake chub and 2) to evaluate habitat conditions at Borax Lake, including the condition of the fragile lake shoreline and outflows. This report describes results from monitoring conducted by Oregon Department of Fish and Wildlife’s Native Fish Investigations Project in 2009.

Evidence from this project and across the range of coho strongly indicates that connectivity in diverse and dynamic tidal habitats provides alternative rearing pathways critical for the sustainability and recovery of Oregon Coastal (OC) coho stocks. Specifically, this project reestablished innovative PIT tag mark recapture techniques to monitor coho movements and migrations. Temporal and spatial components of over-winter rearing strategies, in relation to habitat use and project effectiveness monitoring, is the focus in these paired study streams. Notably, monitoring was shifted to Willanch Creek from Larson Creek. Juvenile coho diet analyses revealed seasonal and diurnal variation in foraging strategies between early migrating sub-yearlings and yearling smolts across their range in estuarine habitats. These results reveal the fundamental mechanisms that promote increased juvenile coho growth and survival in the estuarine ecotone. In conjunction with prior and current data, results highlight the critical importance of these diverse habitats for recovering viable OC coho populations.

The Klamath Basin has long been renowned for the excellent fisheries it provides. Klamath River, Upper Klamath Lake, Williamson, and Wood Rivers are noted for the large trout taken by anglers. Some of the smaller streams in the basin have exceptional fishing for smaller trout. Williamson River and Sprague River have unique fisheries for the Lost River sucker, known locally as mullet. The Lost River system and lower Sprague River provide good angling for warmwater fishes. Angler use is quite extensive throughout the basin. Native stocks are supplemented by hatchery-reared fish in many of the streams. In general, public access to the streams of the Klamath Basin is good, particularly in areas where the demand is greatest. A large amount of publicly owned land in combination with blocks of open land owned by private companies provide this access. However, there are a number of places in the basin which are privately owned and closed to the public. In these places, where a particularly valuable resource is under used, this plan recommends developments which will allow greater public use.

We also sampled dependent population blocks across three monitoring strata (North Coast, Mid Coast, and Mid-South Coast). Using a spatially balanced site selection process (Generalized Random Tessellation Stratification; GRTS) we surveyed 451 unique sites within the range of coho salmon spawning or rearing. With the exception of the 2014 survey year, habitat data were collected during winter conditions (February – March). Habitat sampled in 2014 occurred within the summer field season (June – September). We used a Habitat Limiting Factors Model (HLFM) to estimate habitat capacity for winter coho parr and the HabRate model to assess habitat quality for each surveyed stream reach. HLFM estimates were expanded based on the total coho distribution in each population. Based on the habitat data the HLFM predicted the Floras population could support the highest density of juvenile coho (1568 parr/km), while the streams in the Siltcoos watershed could support the least (290 parr/km). At the ESU-level, there was no detectable change of high quality rearing habitat (= 1850 parr/km) when compared to previous studies, but changes were observed among populations over the course of these survey years. We compared individual habitat metrics across populations, land use, geology, and between independent and dependent populations. While no significant differences were observed between independent and dependent populations, differences in habitat metrics were detected among individual populations, land use types, and geologies. In addition, we detected a difference in reproductive habitat quality (spawning and emergence) between both populations and land use types. Title: Information Report 2018-01; Winter Habitat Condition of Oregon Coast Coho Salmon Populations, 2007-2014 Abstract -- In this report we summarize results of eight years (2007-2014) of habitat surveys for 18 independent Oregon coast coho salmon populations across four monitoring strata (North Coast, Mid Coast, MidSouth Coast, and Umpqua) in the Oregon Coast Coho Salmon Evolutionary Significant Unit (ESU). We also sampled dependent population blocks across three monitoring strata (North Coast, Mid Coast, and Mid-South Coast). Using a spatially balanced site selection process (Generalized Random Tessellation Stratification; GRTS) we surveyed 451 unique sites within the range of coho salmon spawning or rearing. With the exception of the 2014 survey year, habitat data were collected during winter conditions (February – March). Habitat sampled in 2014 occurred within the summer field season (June – September). We used a Habitat Limiting Factors Model (HLFM) to estimate habitat capacity for winter coho parr and the HabRate model to assess habitat quality for each surveyed stream reach. HLFM estimates were expanded based on the total coho distribution in each population. Based on the habitat data the HLFM predicted the Floras population could support the highest density of juvenile coho (1568 parr/km), while the streams in the Siltcoos watershed could support the least (290 parr/km). At the ESU-level, there was no detectable change of high quality rearing habitat (= 1850 parr/km) when compared to previous studies, but changes were observed among populations over the course of these survey years. We compared individual habitat metrics across populations, land use, geology, and between independent and dependent populations. While no significant differences were observed between independent and dependent populations, differences in habitat metrics were detected among individual populations, land use types, and geologies. In addition, we detected a difference in reproductive habitat quality (spawning and emergence) between both populations and land use types. Close

  Citation × Citation Citation Abstract Copy Title: Lamprey Abstract -- The majority of scientific studies on lamprey have investigated biological attributes, with few studies investigating historic abundance, detailed distribution and specific ecological requirements and role. Because of the paucity of information and concerns of declining lamprey population in the Pacific Northwest, the Applegate River Watershed Council (ARWC) with the Medford District of the Bureau of Land Management (BLM) collaborated to study lamprey populations in the Applegate River watershed of southwest Oregon (Close et al. 1995, Larson & Belchik 1998, Kostow 2002). The objectives of the study included: (1) Identifying species composition; (2) determining the distribution of lamprey species; and (3) relating the distribution of lamprey ammocoetes (juveniles or larvae) to physical stream characteristics. This paper summarizes the life histories of the two most common lamprey species in the Oregon, the Pacific (Lampetra tridentata) and Western Brook (Lampetra richardsoni), details the methods of study, reports the results and summarizes the findings. Also included are recommendations and suggestions for future lamprey work in the Applegate basin.

  Citation × Citation Citation Abstract Copy Title: Performance of Progeny From Steelhead and Rainbow Trout Crosses - Final Report 2009 Abstract -- Many salmonids exhibit partial migration: the phenomenon of populations partitioned into migratory and non-migratory individuals (Jonsson and Jonsson 1993). Oncorhynchus mykiss exhibit a complex of life-history strategies ranging from residency in small headwater streams to anadromy involving migrations of hundreds of kilometers. In the Grande Ronde River basin of northeast Oregon, both resident and anadromous life-history forms coexist, and thus populations found there likely exhibit partial migration. Partial migration may have important consequences for anadromous species listed under the Endangered Species Act (ESA). The recent decline of summer steelhead (Oncorhynchus mykiss) populations in the lower Snake River has prompted their listing under the ESA. Declines in steelhead are potentially due to elevated mortality rates associated with anadromous migrations. If resident and anadromous life-history characteristics result from a phenotypically plastic trait (i.e. a genetic trait that is highly variable due to influences from environmental factors), then elevated mortality associated with the anadromous type may be shifting the populations towards residency. Further, although the anadromous expression of the trait may be declining, the trait would not necessarily be lost. Identification of the plasticity of these traits would then be important for the management of these populations. We investigated life history traits of O. mykiss with studies in both the hatchery and natural environment. We anticipated that these complimentary approaches would allow us to evaluate the relationship between the two life-history forms. They should further allow us to explore the feasibility of using hatcheries to produce anadromous progeny from resident parents if the number of anadromous life-history forms becomes severely depressed. The overall goal of this study was to determine the plasticity of life history forms, specifically the ability of resident adults to produce anadromous progeny.

  Citation × Citation Citation Abstract Copy Title: Life history variability, habitat use, and migratory behavior of coastal cutthroat trout in the Salmon River, Oregon Annual Progress Report Abstract -- A previous study characterized a diversity of life history strategies of coastal cutthroat trout (Oncorhynchus clarki clarki) in Salmon River (Krentz 2007). In contrast to life history patterns in other Oregon estuaries (Giger 1972), cutthroat trout of all sizes resided for extended periods of time throughout the available channel habitats in Salmon River estuary. The estuarine resident population appeared to represent a significant portion of the migratory individuals, and included all age classes. Estuary growth was similar to that of their ocean migrant counterparts, and survival in the estuary was high. Because cutthroat were collected and marked primarily within the estuary (Krentz 2007), it is unclear what portion of the migrant population remained in the estuary relative to the ocean migrants, or whether the tagged group was representative of the anadromous populations. The current study was designed to track a representative sample of the downstream migrant population, and assess the relative success (survival) of the estuary and ocean migrants. Similar studies in the Columbia River documented directed and rapid migration through the estuary (Zydlewski et al. 2008, Hering et al. 2009). With one exception, cutthroat trout were not observed to rear in the estuary. In addition, many fish disappeared before reaching the ocean and few of the ocean migrants returned to the site of release. In this study we replicated the study design used in the Columbia River studies to allow comparison of estuary migration and rearing strategies between the two estuaries. The primary objective of our work in the Salmon River was to increase understanding of coastal cutthroat trout biology and the relationship between resident and migratory cutthroat. Study objectives were to: 1. Estimate the distribution and abundance of coastal cutthroat trout in the Salmon River watershed 2. Quantify the proportions of the cutthroat populations that are migratory, identify which individuals migrate and describe the timing of migration 3. Describe habitats used by anadromous migrants and characterize migration behavior within the Salmon River estuary 4. Estimate growth rate of estuary resident cutthroat 5. Estimate estuarine/marine survival of anadromous individuals and document return to estuary 6. Compare migratory patterns and survival with cutthroat in the Columbia River In this report, we will discuss migration patterns, habitat use, and growth. The study will be continued in 2010 to meet objectives (1), (2), and (6), and provide more detail to objectives (3), (4), and (5).
