  Citation × Citation Citation Abstract Copy Title: Juvenile coho salmon movement, growth and survival in a coastal basin of southern Oregon Author: Weybright, Adam D. Juvenile salmonids display highly variable spatial and temporal movement patterns that are influenced by density dependent (e.g., competition, predation) and density independent (e.g., genetics, stream discharge, physical habitat conditions) factors. The effects of these factors differ with fish life history stage, but will ultimately affect how salmonids utilize freshwater nursery habitats and influence their size at smolting. Although juvenile coho salmon (Oncorhynchus kisutch) (Walbaum 1792) movement patterns and their relationships with body mass have been previously examined, the temporal scale considered in most studies has been within individual seasonal periods. In this study, we monitored the movement of PIT tagged juvenile coho salmon throughout the period of freshwater residence in an entire southern Oregon coastal basin to identify the prevalent sedentary and mobile strategies these fish may adopt and to examine possible relationships between those strategies and fish body mass, growth and survival. Specific objectives include: 1) to describe juvenile coho salmon movement strategies and patterns during the freshwater residence period; 2) to determine the relative proportions of juvenile coho salmon that exhibit each movement strategy; 3) to establish whether juvenile coho salmon body mass and growth rates are related with a set of habitat variables recorded during this study; 4) to determine whether coho salmon body mass or growth rates are related to movement strategy; and 5) to evaluate whether winter survival of juvenile coho salmon is associated with movement strategy. Results revealed seasonally and spatially variable movement. More than half of coho salmon tracked throughout the period of freshwater residence exhibited movement behavior that differed between summer and winter seasons. Within seasonal periods, coho salmon in tidally affected reaches exhibited greater prevalence of mobile behavior relative to those in riverine reaches. Regression analysis indicated coho biomass density, habitat unit structural complexity and size at tagging were important in predicting summer growth of coho salmon. Juvenile coho salmon that were mobile during summer were either larger or no different in body mass in early summer relative to fish that exhibited sedentary behavior. Similarly, no consistent differences were observed between sedentary and mobile coho salmon in regards to summer growth. Coho salmon that were sedentary in summer and winter experienced higher apparent winter survival than mobile fish in each season, though the reach in which an individual resided at the start of winter appeared to also affect survival. Coho salmon residing in the tide gate reservoir reach and mainstem headwater reaches experienced greatest apparent winter survival. These results indicate that juvenile coho salmon movement within a stream basin is spatially and temporally variable and that mobility does not necessarily indicate inferior competitive ability. In a broader context, variable movement patterns reflect the capacity for plastic behavior in salmonids and this research demonstrates the importance of maintaining seasonally diverse freshwater and estuarine nursery habitats for juvenile fish.

• 34. [Article] Growth, residence, and movement of juvenile Chinook salmon within restored and reference estuarine marsh channels in Salmon River, Oregon.

  Citation × Citation Citation Abstract Copy Title: Growth, residence, and movement of juvenile Chinook salmon within restored and reference estuarine marsh channels in Salmon River, Oregon. Author: Hering, David K. Tidal wetland channels provide rearing habitat for juvenile Chinook salmon as they emigrate from freshwater habitat and prepare to enter the ocean. Widespread diking and drainage of estuarine marshes for agricultural and urban development may have contributed to a decline in salmon abundance in the Pacific Northwest, prompting efforts to restore estuarine salmon habitat in the region. I investigated the growth and residence patterns of age-0 Chinook salmon in two blind tidal channels in the Salmon River estuary, Oregon. One channel drained a natural high salt marsh in “reference” condition, and the other channel was in an adjacent salt marsh, restored to tidal inundation in 1996 after being diked and controlled by a tide gate for thirty five years. Recapture of individually marked fish indicated salmon growth rates were similar in the two channels, though growth rates varied more seasonally in the restored site. Average minimum residence times of individual fish were approximately ten days in each channel, and individual salmon were observed up to 79 and 117 days after initial marking in the reference and restored channels, respectively. To characterize movement of age-0 salmon within tidal channels, I tested the feasibility of stationary Passive Integrated Transponder (PIT) detection within a small (approximately 8m wide) tidal channel within the natural marsh system. I found that a stationary PIT detector was an effective tool for monitoring tagged fish movement in a brackish water channel network. Salmon movements in the channel were asymmetrical about high slack tide, with peak movement frequency occurring late during both flood and ebb tide periods. Most movements were in the direction of tidal currents, but 20% of individuals entered the channel against the ebbing tide. Individuals occupied the intertidal channel for a median 4.9 hours and as long as 8.9 hours per tidal cycle, and few were detected moving when water depth was <0.4m. Some individuals used the channel on multiple successive tidal cycles, and others entered intermittently over periods up to 109 days. This research used individual-based fish marking methods to quantify juvenile Chinook salmon behavior and performance within tidal marsh channels, assessing functional equivalence of natural and restored sites and demonstrating the value of such habitats for conservation and restoration of salmon populations.

Author: Weitkamp, Laurie A., Brodeur, Richard D., Daly, Elizabeth A. Successfully shifting to a more piscivorous diet may be an important factor in the growth and survival of juvenile coho salmon Oncorhynchus kisutch and Chinook salmon O. tshawytscha during their first summer in the northern California Current. Nonmetric multidimensional scaling and cluster analysis of diets by size showed several distinct groupings as the salmon grew during their first marine summer. These size-based diet differences were clearly driven by increased rates of piscivory for both species. Fish prey composition, feeding intensity, and fish prey-predator length ratios all significantly increased for coho salmon at approximately 240 mm fork length when they changed from diets dominated by juvenile rockfishes Sebastes spp., the larvae of crabs Cancer spp., and adult euphausiids to one of predominantly juvenile forage fish. As Chinook salmon grew, they gradually increased the proportional contribution (by weight) of fish prey in their diets-from 55% in the smallest length-class examined (80-100 mm) to 95% in the largest one (. 375 mm). Chinook salmon fed in the same marine environments as coho salmon and consistently ate more and longer fish prey at a given size than coho salmon but had lower overall feeding intensity, perhaps owing to a higher level of prey selection. Relating subsequent interannual adult salmon returns to juvenile diets showed mixed results. During lower-survival years, coho salmon ate fewer and smaller fish prey, while subyearling Chinook salmon had less total food and more empty stomachs. We did not find consistent trophic patterns for yearling Chinook salmon in relation to their ultimate survival.

  Citation × Citation Citation Abstract Copy Title: Bioenergetics and survival of chum (Oncorhynchus keta) and pink (O. gorbuscha) salmon in heated seawater Author: Kepshire, Bernard Michael The use of heated seawater for enhancing the culture of Pacific salmon was investigated. Food consumption rate, gross food conversion efficiency, growth rate, and survival of chum (Oncorhynchus keta) and pink (O. gorbuscha} salmon fed to satiation were determined in relation to water temperature and body weight. Both species of salmon were raised at temperatures of 55°, 60°, 65°, and 70°F. The highest food consumption rate, gross food conversion efficiency, growth rate, and survival of chum salmon occurred at temperatures of 65°, 55°, 55°-65°, and 55°F, respectively, while those of pink salmon occurred at 65°, 55°-65°, 60°-65° and 55 -60°F, respectivety. The response to all conditions measured was poorest for chum and pink salmon at 70°F. Pink salmon generally had a higher food consumption rate, gross food conversion efficiency, and growth rate than chum salmon. Food consumption rate, gross food conversion efficiency, growth rate, and survival of chum and pink salmon decreased as body weight increased. As body weight increased, food consumption rate, gross food conversion efficiency, and growth rate generally decreased more at 60°-65°F than at 55°F for chum salmon, and more at 65°-70°F than at lower temperatures for pink salmon. Survival was influenced by behavior and disease in addition to temperature. Diseases encountered were bacterial kidney disease and vibriosis, of which the former was most prevalent. Chum and pink salmon can be cultured in heated seawater at temperatures not exceeding 65°F. Good growth (>5% gain in body weight/day) and survival (60-100%) can be expected.

  Citation × Citation Citation Abstract Copy Title: Foreign and domestic trade in canned salmon of the U.S. and Canada : the effect on the derived demand of the fishermen Author: Onuorah, Michael Chukwuemeka The principal objective of the study was first to present a historical discussion of foreign and domestic trade in canned salmon in the United States and Canada, and secondly, to estimate the ex-vessel derived demand characteristics for red and pink salmon facing the fishermen in both countries. Secondary sources were used to satisfy the first objective. With respect to the second objective, the least squares method was employed in the estimation of the coeffients of the various linear equations. With these coefficients from the demand equations, price flexibilities were computed at the mean values of the ex-vessel price and quantity (landings) figures (1956 to 1970 (U.S.) and 1947 to 1970 (Canada)). The statistical results indicated that prices are rather inflexible relative to landings. The price flexibility in the U.S. and Canada is almost the same. In each case, a ten percent increase in landings would tend to depress the ex-vessel prices of red and pink salmon by a smaller percentage. The impact of institutional change on the demand for canned salmon was investigated. Britain in 1958 relaxed its restrictive policy on imports of salmon. It was discovered that such an institutional change had a significant effect on the demand analysis of red salmon in the U.S. and Canada; however, the effect on the demand analysis of pink salmon in both countries was inconclusive.

This paper focuses on estimates of demand functions for Norwegian salmon products. Log-linear functions are used to construct the model. The major objective of the research is to define the own-price elasticity of demand, income elasticity of demand, and cross-price elasticity of demand in the context of the salmon industry. The research findings are hoped to bring some added values to the improved teaching and educational training at Nha Trang University, in addition to providing salmon importers in Vietnam with scientific foundations for making relevant, appropriate decisions in the fast-moving economic integration process. A further step is to compare these findings with those from recent studies cited in literature about theoretical and empirical dimensions of salmon demand.
