Stress Nutrition in Aquatic Animals: From Definition to Practice

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts

Effects of Prawn Shell Meal Diets on Hemocyte Count, Hemolymph Clotting, and Sperm Quality of the Freshwater Prawn Macrobrachium caementarius

Aquaculture Research, Volume 2026, Issue 1, 2026.
Crustacean shells are composed of chitin, which is bound to protein and minerals, along with other essential nutrients. These components are necessary for growth, immune response, the formation of reproductive structures, and the enhancement of sperm quality.

Revealing Chronotypes Across Aquatic Species Using Acoustic Telemetry

Fish and Fisheries, Volume 26, Issue 6, Page 1134-1145, November 2025.
ABSTRACT Acoustic telemetry offers valuable opportunities to investigate individual variability in circadian‐related and other behaviours and how environmental cues shape these patterns in wild fish populations. However, this potential has not yet been fully exploited.
