The detection of pathogens at early stages of infection is a key point for disease control in aquaculture. This work by Dagoberto Seplveda et al, University Catlica de Valparaso, Chile, aims to design a unique RT-qPCR assay for pathogen detection in the three …

Enteric Redmouth Disease (ERM), caused by Yersinia ruckeri, is one of the most important infectious diseases in rainbow trout (Oncorhynchus mykiss) aquaculture in Europe. More recently, non-motile vaccine resistant isolates appear to have evolved and are causi…

For many farming practices, the capture, handling and transport of fish is an essential requirement; however with each of these activities found to be a stressful process, what are the implications for fish welfare? Hannah Chilvers, writing for TheFishSite.com…

Samantha L White et al, Fisheries and Oceans Canada, examined levels of mRNA in domesticated, wild and hybrid rainbow trout (Oncorhynchus mykiss) to investigate the influence of genotype (domesticated vs. wild, and their interactions in hybrids) and developmen…

Scientists are seeking to improve the health benefits of rainbow trout by using dietary coriander oil along with vegetable oil to improve fatty acid composition in the fillet.

Imagine having a daylong Thanksgiving feast every day for a month, then, only paupers rations the rest of the year. University of Washington researchers have discovered Dolly Varden, a kind of trout, eating just that way in Alaskas Chignik Lake watershed.

A six-week feeding trial was conducted to investigate the suitability of animal oils as total replacement for cod liver oil (CO) in rainbow trout juvenile feeds. The effect of animal fats on the growth performance, survival and fatty acid profile was measured.…

Researchers from the USDA/ARS National Center for Cool and Cold Water Aquaculture, Leetown, USA have conducted genome scans of rainbow trout families from a single broodstock population to identify the effect quantitative trait loci (QTL) have on stress respon…
