Reviews in Aquaculture, Volume 17, Issue 1, January 2025.ABSTRACT Studies have demonstrated adverse effects of global warming on aquatic ecosystems. However, the effects of increased water temperature (IWT) on fish reproduction are still doubtful in species spawning at low or high temperatures. In this meta‐analysis, we elucidated the effects of global warming on spermatozoa functions, key determinants of ...

Genetic diversity of tambaqui broodstocks in stock enhancement programs
Semina: Ciências Agrárias, 2017 Natural populations of tambaqui (Colossoma macropomum) have significantly decreased in recent decades especially due to human extraction activities. So that the environmental impact may be reduced, the restocking of fish and increase in fish production are enhanced. Genetic evaluations using molecular markers are essential for this purpose.

Aquaculture Research, Volume 2025, Issue 1, 2025.The study investigated how phytobiotic‐supplemented diets impact the growth performance, feed utilisation and resistance of Nile tilapia (Oreochromis niloticus) to Streptococcus agalactiae. Fish with a total mean initial mass (37.6 g) of 180 and a random stocking of 15 fingerlings per 150 L tank in triplicate were divided into four groups and fed ...
