Gut physiology of rainbow trout (Oncorhynchus mykiss) is influenced more by 1 short-term fasting followed by refeeding than by feeding fishmeal-free diets

The study shows that short-term fasting followed by refeeding significantly alters gut and liver physiology in rainbow trout, regardless of diet composition, while diet changes have minimal impact during refeeding.

Yeast extract improves growth in rainbow trout (Oncorhynchus mykiss) fed a fishmeal-free diet and modulates the hepatic and distal intestine transcriptomic profile

This study evaluates the effects of adding yeast extract to a fishmeal-free diet on rainbow trout growth and transcriptomic profiles, finding improved growth and modulated gene expression.

Housing conditions affect adult zebrafish (Danio rerio) behavior but not their physiological status

This study evaluates how different housing conditions affect adult zebrafish behavior and physiology, finding no impact on stress biomarkers but highlighting skin mucus as a viable cortisol measurement method.
