Rapid Quantification of Fatty Acids in Fish Eggs Through Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Omega‐3 fatty acids (FAs) are important indicators for egg quality. This study uses Raman spectroscopy coupled with chemometrics to develop a rapid and in situ method for predicting FA composition in fish eggs. These findings offer a practical and cost‐effective method for assessing egg FA profiles in aquaculture hatcheries.

Can we identify wild-born salmon from parentage assignment data? A case study in the Garonne-Dordogne rivers salmon restoration programme in France

Aquatic Living Resources, 2021
Parentage assignment with genomic markers provides an opportunity to monitor salmon restocking programs. Most of the time, it is used to study the fate of hatchery-born fish in those programs, as well as the genetic impacts of restocking.

Age and length composition of Columbia Basin chinook, sockeye, and coho salmon at Bonneville Dam in 2000 [PDF]

, 2001
In 2000, representative samples of adult Columbia Basin chinook (Oncorhynchus tshawytscha), sockeye (O. nerka), and coho salmon (O. kisutch), populations were collected at Bonneville Dam. Fish were trapped, anesthetized, sampled for scales and biological

Experimental Evidence for Mobilization of Mercury From the Eggshell by the Developing Embryo in an Avian Model Organism

Environmental Toxicology, EarlyView.
ABSTRACT Of the many pollutants wildlife is exposed to, mercury ranks among the most toxic. In birds, mercury does not only accumulate within generations, but also is transferred across generations via maternal offloading in eggs, with higher mercury concentrations found in shells of unhatched eggs.

Hatchery supplementation provides a demographic boost but alters age composition of sockeye salmon in Auke Lake, Southeast Alaska

Evolutionary Applications
Evaluating salmon hatchery supplementation programs requires assessing not only program objectives but identifying potential risks to wild populations as well.

Evaluating the Potential Fitness Effects of Chinook Salmon (Oncorhynchus tshawytscha) Aquaculture Using Non-Invasive Population Genomic Analyses of MHC Nucleotide Substitution Spectra

Animals, 2023
Genetic diversity plays a vital role in the adaptability of salmon to changing environmental conditions that can introduce new selective pressures on populations.

A tale of two hatcheries: Assessing bias in the hatchery process for Atlantic salmon (Salmo salar L.) [PDF]

, 2014
Stock enhancement of Atlantic salmon (Salmo salarL.), a fish of considerable economic and social importance, is commonplace. Supportive-breeding is a well-recognised method of enhancement which, when compared with traditional hatchery practices, is ...

Initial responses of Chinook salmon (Oncorhynchus tshawytscha) and steelhead (Oncorhynchus mykiss) to removal of two dams on the Elwha River, Washington State, U.S.A.

Frontiers in Ecology and Evolution
Large dam removal is being used to restore river systems, but questions remain regarding their outcomes. We examine how the removal of two large dams in the Elwha River, coupled with hatchery production and fishing closures, affected population ...

Transcriptional breakpoints as predictors of thermal thresholds in a climate‐impacted stenothermal fish

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The biogeography of ectotherms is greatly influenced by their thermal tolerance, which is expected to be tightly coupled to aerobic performance. However, preferred temperatures of ectotherms often deviate substantially from aerobic performance optima. This suggests that
