Elevated water temperature in combination with an increase in daylength stimulate a synchronized onset of spermatogenesis in male Atlantic salmon (Salmo salar, L.) postsmolts

Journal of the World Aquaculture Society, Volume 55, Issue 5, October 2024.
Abstract Male postsmolt maturation (“jacking”) is undesired in Atlantic salmon aquaculture due to economic and welfare impacts. Unfortunately, incidence of jacking has increased linked to intensive rearing conditions. This study subjected 1000 salmon (52.1 ± 5.2 g) to one of two temperatures (15, 12.5°C) and one of two photoperiods (constant light‐LL ...

A Brief Review on Aflatoxicosis in Aquaculture With a Focus on Fish

Aquaculture Nutrition, Volume 2024, Issue 1, 2024.
Feed quality is among the most determinative criteria for aquaculture success. Along with feed ingredient quality and its production process, feed storage conditions would also affect feed quality, especially in terms of adventitious toxins. Mycotoxins are frequent food and feed contaminants and are considered important health threats to both human and
