“…While we observed higher growth rates in the multi-habitat enclosure, all growth rates (>1.1 mm/d for both enclosures) were very high compared with published data for juvenile salmon growth in California. In the Yolo Bypass, published apparent growth rates range from 0.52 to 0.80 mm/d (Sommer et al 2001), with a similar range reported for subyearling Chinook Salmon growth on the central California coast (MacFarlane et al 2005). Therefore, despite the significant difference between enclosures, the growth rates we observed were so much higher than what has been reported in previously published work that the ecological difference is likely negligible and does not signal physiological stress in the downstream comparison enclosure.…”

Passive integrated transponder (PIT) technology allows passive, individual identification of small fish, making it a potentially useful tool to address an information gap of juvenile salmon habitat use in off‐channel environments. We investigated the combined use of field enclosures and PIT technology as a method for studying the habitat preference of juvenile Chinook Salmon Oncorhynchus tshawytscha on a flooded rice field, a potential surrogate for lost floodplain habitat. We stocked two field enclosures (182 m2) with 42 juvenile salmon. One enclosure had equal portions of rice stubble, disced, and fallow habitat treatments, and the second contained only the disced treatment. Fish were tagged with 8‐ or 12‐mm‐sized PIT tags, and generated approximately 1 million detections in each enclosure over 14 d. We used a condensing procedure to reduce the data volume while preserving habitat use patterns. The smaller 8‐mm tags were only detected along antenna edges, and the 12‐mm tags had broader but more variable detection fields. Despite this difference, habitat occupancy probabilities showed the same spatial pattern between tag sizes, with increased occupancy in the upstream locations of both field enclosures. Similar results between tag sizes suggest that valuable habitat use data can be obtained with the 8‐mm tag. Received January 30, 2015; accepted October 13, 2015

“…Because of uncertainty in determining the time of movement of fish from the freshwater to the estuary and the estuary to the ocean from scales, we combined the first year of growth in the analyses. Importantly, it has been demonstrated that some Chinook salmon populations have substantial inter‐annual variation in their period of estuarine residence that is dependent on some of the same environmental variables we are examining (MacFarlane et al. , 2005).…”

We model age-specific growth rates of Chinook salmon (Oncorhynchus tshawytscha) with two life-history behaviors from Alaska (i. Situk and ii.Taku Rivers), Puget Sound, Washington (iii., iv. Skagit River), and California (v. Smith River) relative to oceanic conditions in those regions. By analyzing over 20 yr of biological and physical data from the NE Pacific downwelling, upwelling, and transition zones, we are able to determine the factors affecting growth across much of the species' range and between life-history behaviors. With scale increment data from returning fish, we use path analysis and partial least squares regression to quantify the relationships between growth and regional-and large-scale oceanic conditions (e.g., sea level height, sea surface temperature, upwelling). Alaskan fish with both ocean-and stream-type behaviors were fit best by the environmental data from the winter in Alaska waters. Specifically, coastal and gyre factors such as sea surface temperature, river flow, and Ekman pumping positively correlated to growth, indicating a productive and strong Alaska Current promoted growth. Growth of fish from California was fit by local factors such as increased upwelling, lower coastal sea surface temperature, and wind stresses during summer and spring, indicating a productive and strong California Current promoted growth. For Puget Sound, Washington, growth of fish that migrate to sea in their first year was generally negatively correlated to a strong California Current. Puget Sound fish that spend a year in freshwater before migrating to sea were modeled well with environmental data from their source region for the first 2 yr at sea and by data from Alaska waters in their third year at sea. Results suggest that conditions in which the transition zone is dominated by neither the Alaska nor California Currents are best for increased growth of Puget Sound fish.

“…The mass increment of salmonids increases rapidly after entering sea water (Jonsson & Jonsson, 2003), and temperature appears to be one of the major abiotic factors influencing growth. Investigations of O. tshawytscha in the Gulf of the Farallones, central California, revealed that post‐smolts grew better and had higher energy storage in a warm year with reduced salinity and elevated zooplankton productivity than in colder years with higher salinity (Macfarlane et al , 2005). Similarly, the growth increment of the one‐sea‐winter S. salar was higher in years with large areas with relatively high water temperature and high North Atlantic Oscillation index (NAOI) in May, the month when the smolts moved to sea (Friedland et al , 2000; Jonsson & Jonsson, 2004 b ).…”

The present paper reviews the effects of water temperature and flow on migrations, embryonic development, hatching, emergence, growth and life-history traits in light of the ongoing climate change with emphasis on anadromous Atlantic salmon Salmo salar and brown trout Salmo trutta. The expected climate change in the Atlantic is for milder and wetter winters, with more precipitation falling as rain and less as snow, decrease in ice-covered periods and frequent periods with extreme weather. Overall, thermal limits for salmonids are species specific. Scope for activity and growth and optimal temperature for growth increase with temperature to an optimal point before constrain by the oxygen content of the water. The optimal temperature for growth decreases with increasing fish size and varies little among populations within species, whereas the growth efficiency may be locally adapted to the temperature conditions of the home stream during the growth season. Indirectly, temperature influences age and size at smolting through its effect on growth. Time of spawning, egg hatching and emergence of the larvae vary with temperature and selective effects on time of first feeding. Traits such as age at first maturity, longevity and fecundity decrease with increasing temperature whilst egg size increases with temperature. Water flow influences the accessibility of rivers for returning adults and speed of both upstream and downstream migration. Extremes in water flow and temperature can decrease recruitment and survival. There is reason to expect a northward movement of the thermal niche of anadromous salmonids with decreased production and population extinction in the southern part of the distribution areas, migrations earlier in the season, later spawning, younger age at smolting and sexual maturity and increased disease susceptibility and mortality. Future research challenges are summarized at the end of the paper.
