Aquaculture Nutrition, Volume 2025, Issue 1, 2025.This study aimed to assess the impact of incorporating rapeseed meal (RM) as a partial substitute for fish meal (FM) in the diet of cultured hybrid sturgeon (Acipenser schrenckii ♀ × Acipenser baerii ♂). A total of 450 juvenile hybrid sturgeon with similar weights were randomly assigned to five dietary groups, each with triplicates of 30 fish per tank.

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.Global climate change significantly influences environmental temperature, affecting the feeding patterns, growth, and overall health of fish. Understanding how fish respond to thermal changes is crucial, particularly for growth and stress response in aquaculture. This study examines the effects of different acclimation temperatures on the expression of

Acta Physiologica, Volume 240, Issue 12, December 2024.Abstract Aim In most vertebrates, oxygen deprivation and subsequent re‐oxygenation are associated with mitochondrial impairment and excess production of reactive oxygen species (ROS) like hydrogen peroxide (H2O2). This in turn triggers a cascade of cell‐damaging events in a temperature‐dependent manner.

Prevention of acute ammonia toxicity in bluga (Huso huso), using natural zeolite
Journal of Toxicology and Environmental Health Sciences, 2013 This study was accomplished to examine the efficiency of natural zeolite in preventing acute toxicity of total ammonia to Huso huso. The study was performed using Water Static Method in 96 hours. Fish averaged 46 5 g in weight and 22 4 cm in total length were exposed to four different concentrations (15, 30, 50, 75 mgL-1) of ammonia and a group was
