  Citation × Citation Citation Abstract Copy Title: Catherine Creek Spring Chinook Salmon Hatchery Program Review - 2011 Abstract -- This paper provides background information, program development history, and an assessment of program performance for the Catherine Creek spring Chinook salmon hatchery program. We cover the time period from initiation of the program in the mid-1990s to present. General background information and pre mid-1990s hatchery program performance were previously presented in Grande Ronde Basin Spring Chinook Salmon Hatchery Review: Introduction and the Early Years. The Catherine Creek spring Chinook hatchery program was initiated with collection of wild parr for the Captive Broodstock Program in 1995 due to the depressed status of this population (Figure 1). Adult trapping and smolt acclimation facilities were constructed to implement the program and are operated by the Confederated Tribes of the Umatilla Indian Reservation (CTUIR). These facilities function as satellite facilities of Lookingglass Fish Hatchery (Figure 2). Lookingglass Fish Hatchery (LFH) serves as the adult holding, spawning, incubation, and rearing facility for the program. Smolts are transported from LFH to the Catherine Creek acclimation ponds for a short period of acclimation in the spring prior to release. Annual adult mitigation, smolt production, and brood year specific smolt-to-adult return goals were developed for the Catherine Creek program to represent 16.67% of the total Grande Ronde River basin goals (Table 1).

  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).

In 1998, the Oregon Department of Fish and Wildlife (ODFW) initiated a comprehensive program to monitor the status of coho salmon (Oncorhynchus kisutch) populations and aquatic habitat in coastal drainages of Oregon (OWEB 2003). A 2005 assessment by ODFW concluded that Oregon coastal coho were viable at the scale of the Evolutionary Significant Unit (ESU) and demonstrated resilience in response to improving ocean conditions. Yet 7 of 21 (33%) individual populations within the ESU failed one or more of five criteria used to assess viability (Chilcote et al. 2005), and it is uncertain whether productivity levels across the ESU will recover sufficiently to withstand future periods of poor ocean conditions. The coho population in Salmon River was the only population in the ESU to fail all five viability criteria. Uncertainty remains about the response of Oregon coastal coho salmon to different combinations of freshwater and marine limiting factors, complicating recovery efforts (Lawson 1993; Lawson et al. 2004; IMST 2006). Such uncertainty cannot be resolved entirely by existing Oregon Plan monitoring programs, which target only a portion of the habitats and coho salmon life stages in large river basins, and with few exceptions (e.g., Johnson et al. 2005), were not designed to test population responses to individual management manipulations. In 2007, in response to the failure of viability criteria, ODFW managers discontinued releases of hatchery coho salmon into Salmon River as one of the primary management actions under the Oregon Conservation Plan for the Oregon Coast Coho Evolutionarily Significant Unit (hereafter “coho plan,” Nicholas 2006). This change affords the first opportunity in Oregon to monitor the results of a large scale experiment in removing hatchery coho salmon from a basin for at least four generations (twelve years). Hatchery production has been a centerpiece of salmon management for decades, but rarely has full recovery from hatchery influence been given a chance to succeed. Salmon River offers a test basin to explore whether an independent population of coho salmon can recover from a prolonged period of very low abundance following removal of the primary factor limiting productivity. Here we describe the first year of a study to monitor the dynamics of the coho salmon population in the Salmon River basin on the central Oregon coast and to determine whether management changes targeting both hatchery influence and stream habitat complexity improve population viability. This research will validate assumptions about factors limiting coho recovery and determine whether recovery measures proposed by the Coho Plan have been effective. Our research is designed to document changes in population abundance, distribution, and life history structure of coho salmon following the removal of hatchery coho salmon from the watershed. It integrates adult, juvenile, and habitat components to establish links and describe variability between juvenile performance and adult recovery. It also monitors the coho salmon population across habitat types and life history stages to identify population responses at a landscape scale. We will establish the link between productivity and survival at each salmon life stage and recovery of the adult population. From these indicators, we will determine the potential resiliency of coho salmon, detail the biological benefits/tradeoffs of returning the ecosystem to natural salmon production, and assess whether supplementation should remain an option in Salmon River. As a conceptual framework, our research design and analyses are guided by the “viable salmonid population” criteria identified by McElhany (2000) and modified by Chilcote et al. (2005) and Nicholas (2006), including abundance, productivity, distribution, diversity, and habitat quality. The results of our new research will be integrated with habitat survey and adult population data collected under the existing Oregon Plan monitoring program and coho salmon population and life history data available from previous Salmon River surveys (Mullen 1978, 1979; Cornwell et al. 2001; Bottom et al 2005; Volk et al. in review). Together these data will address four principal objectives: 1. Quantify viability of the coho salmon population before and after hatchery coho salmon are removed from Salmon River. 2. Assess whether viability of the Salmon River coho population is limited by quantity and complexity of stream habitat. 3. Describe the diversity of juvenile and adult life histories of coho salmon in the Salmon River basin and estimate the relative contributions of alternate juvenile life history to adult returns. 4. Determine salmonid use and benefits of restored tidal wetlands before and after hatchery coho salmon are removed from Salmon River. By synthesizing historic data with new information for the Salmon River basin, we will compare population structure during three distinct periods – pre-hatchery (1974-77), hatchery (1990-2008), and post-hatchery (2009-2013). This annual report discusses the activities and findings from 2008, the first year of the multi-year project, including coho salmon distribution and abundance on the Salmon River spawning grounds, juvenile abundance and distribution in the watershed and estuary, migration timing, and life history diversity.

  Citation × Citation Citation Abstract Copy Title: Downstream rearing of juvenile Chinook salmon abundance, distribution and growth in the Upper Mainstem of the John Day River Abstract -- Juvenile spring Chinook (Oncorhynchus tshawytscha) emerge from the gravel in the late winter or early spring, and most follow a life history pattern known as Natal Reach Rearing (NRR) in which juvenile fish remain in the stream reaches where they were spawned until their second spring of life when they start migrating towards the ocean (Healey 1991). However, in Columbia River tributaries, some juveniles have been observed following a Downstream Rearing (DSR) life history, in which they start moving downstream during their first spring towards other nursery habitats or perhaps ocean rearing (Copeland & Venditti 2009; Schroeder et al. 2016). Rearing in different habitats during their first year gives fish with these two life histories access to diverse food resources and, it is hypothesized that, this leads to different survival and growth advantages for these two groups. Differences in growth are of interest in efforts to conserve this threatened species because size is positively correlated to survival for salmon across multiple stages of their life cycle (Groot & Margolis 1991; Healey 1991; Quinn & Peterson 1996; Roni et al. 2012) Chinook salmon in the upper John Day River, Oregon, exhibit both NRR and DSR life history patterns. Fish following the DSR life history pattern are larger than NRR fish late in the spring, possibly due to factors such as higher fish density, lower stream productivity, and colder water temperatures in their natal reach than in the downstream reaches. However, this size advantage may be lost due to adverse summer conditions. Hot summer days combined with the withdrawal of water for agriculture lead to stream water temperatures well above lethal thresholds for salmon in many downstream reaches. DSR fish have been observed in tributaries of the mainstem John Day River, however their growth and survival during summer is unknown.
