Background Infection with the myxozoan parasite Parvicapsula pseudobranchicola causes disease in wild and farmed salmonids in Norway. In the northeast Pacific Ocean, the parasite has been reported in Pacific salmon Oncorhynchus spp.

Olfactory Imprinting of Amino Acids in Lacustrine Sockeye Salmon
Juvenile salmon have an olfactory ability to imprint their natal stream odors, but neither the odor properties of natal stream water nor the imprinting timing and duration have been clarified as yet. Here we show, using electrophysiological and behavioral experiments, that one-year-old lacustrine sockeye salmon (Oncorhynchus nerka) can be imprinted ...

Understanding Smolt Survival Trends in Sockeye Salmon [PDF]
Abstract Many populations of Sockeye Salmon Oncorhynchus nerka in the eastern North Pacific Ocean experienced significant productivity declines that began about 1990, but there is no consensus on the mechanisms responsible. To better understand Sockeye Salmon survival trends, we examined the 50-year time series for two age-classes of ...

Decadal Rapid Change in Energetic Carrying Capacity for Juvenile Chum Salmon in the Sanriku Coast
ABSTRACT Adult returns to coastal rivers in Sanriku, located near the southernmost area of chum salmon distribution, have declined since 2010. Climate‐induced fluctuations in juvenile prey availability may affect growth and survival, which are linked to adult returns.

Assessing the limiting factors for re-introduction of sockeye salmon to the Coquitlam Water Supply Area [PDF]
Prior to the construction of the dams, migrating salmonid species accessed the upper reaches of the Capilano, Seymour, and Coquitlam watersheds as an integral part of their natural lifecycle.

ABSTRACT Small pelagic fish and other forage species are patchily distributed over space and time, resulting in variable foraging conditions experienced by their predators. The high‐resolution data necessary to understand the spatiotemporal structure of forage communities are challenging to collect with expensive fishery‐independent surveys, meaning ...

Effects of handling stress on Osmoregulation of Juvenile Sockeye Salmon (Oncorhynchus nerka) in Seawater [PDF]
Effects of handling stress on osmoregulatory ability of juvenile sockeye salmon (Oncorhynchus nerka) were investigated to assess responses of fish sampled for physiological studies.

Phasing of muscle gene expression with fasting-induced recovery growth in Atlantic salmon [PDF]
Background: Many fish species experience long periods of fasting in nature often associated with seasonal reductions in water temperature and prey availability or spawning migrations. During periods of nutrient restriction, changes in metabolism occur to
