Skin injury causes fibroblast dysfunction and lowers collagen production. Safe, functional ingredients such as vitamin C (Vit C) and fish hydrolyzed collagen (HC) have been used to alleviate this problem. Defatted HC from salmon (Oncorhynchus nerka) skin

The Origins of New Zealand's Chinook Salmon, Oncorhynchus tshawytscha [PDF]
Chinook salmon, Oncorhynchus tshawytscha, are well established as anadromous and landlocked runs in New Zealand. Ova introductions during the 1870's (probably from the McCloud River, California, U.S.A.), failed to generate anadromous stocks, but further ...

Differences in early developmental rate and yolk conversion efficiency in offspring of trout with alternative life histories [PDF]
Partial migration, in which some individuals of a population migrate while other individuals remain resident, is generally associated with ontogenetic shifts to better feeding areas or as a response to environmental instability, but its underlying ...

Salmon watershed archetypes: A clustering of cumulative pressures and climate change
Cumulative effects of land‐use change and climate change are leading to biodiversity decline globally. Spatial analyses of cumulative pressures that distill complexity and provide actionable information for the management of cumulative pressures on vulnerable species are needed.

The ability to distinguish between different migratory behaviours (e.g., anadromy and potamodromy) in fish can provide important insights into the ecology, evolution, and conservation of many aquatic species.

Aspects of the washout of salmonid eggs. 6. Information on gravel composition , redd sites, the dimensions of redds and the depth of egg burial [PDF]
Sampling was concentrated on the North Moor region and the series of ditches which drained this area to the Bristol Channel. Although most ditches were not deep the mud substratum precluded sampling from within the habitat.

Abstract Biologists often use organismal thermal tolerance to help explain or forecast responses of populations to climate change. Yet many studies quantify thermal tolerance under isolated laboratory conditions despite extreme events, such as heatwaves, often coinciding with other stressors such as nutrient or food limitation.

Spatial and ecological structure of the sockeye salmon population Oncorhynchus nerka of Kuril Lake [PDF]
This study examines the genetic structure of sockeye salmon populations in Kuril lake basin, focusing on the allelic frequencies of SNP loci that potentially carry an adaptive load. Our results reveal the division of sockeye salmon populations into three

How has parasitism changed for Alaskan salmon over the past several decades? Parasitological assessments of salmon are inconsistent across time, and though parasite data are sometimes noted when processing fillets for the market, those data are not ...

ABSTRACT Fish passage development is a priority at Tieton Dam, on the Tieton River in Washington state, because passage options were not included when the dam was constructed nearly 100 years ago. To inform downstream passage design, we conducted a study to evaluate migration and near‐dam behavior of juvenile salmon.
