Early Nutritional Programing: Unlocking the Potential of Fish for Sustainable Aquaculture

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Nutritional programing, which explores the link between early nutritional conditions and their long‐term effects on animals, is a developing field within fish biology. Suboptimal nutritional status during early life is strongly associated with a higher risk of metabolic consequences later in life, including permanent growth retardation, impaired neural

Protein phosphorylation in spermatozoa motility of Acipenser ruthenus and Cyprinus carpio [PDF]

Reproduction, 2017
Spermatozoa of externally fertilizing freshwater fish possess several different modes of motility activation. Spermatozoa of common carp (Cyprinus carpioL.) are activated by hypoosmolality, whereas spermatozoa of sterlet (Acipenser ruthenus) require Ca2+ and low concentration of K+ for motility activation.

Tracking Aquatic Biodiversity With Environmental DNA: A Study in Quebec's Mining Region

Environmental DNA, Volume 7, Issue 5, September–October 2025.
This study assesses the effectiveness of environmental DNA (eDNA) for monitoring fish species in mining‐impacted waters of Quebec's James Bay region. eDNA analyses detected key species, including culturally significant ones, and revealed potential biodiversity impacts, such as reduced detectability of lake sturgeon in areas with habitat disturbance and

Artemia Enrichment Strategies: A Comprehensive Review of Nutritional Enhancements With Emphasis on Fatty Acid Profiles in Aquatic Species

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Artemia (brine shrimp) is a foundational live feed in global aquaculture, renowned for its adaptability, ease of production, and favorable nutritional profile. However, in its natural state, Artemia contains suboptimal levels of highly unsaturated fatty acids (HUFAs), particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA ...

Implications of climate‐change‐induced stressors and water management for sterlet populations in the Middle and Upper River Danube

River Research and Applications, Volume 41, Issue 2, Page 448-465, February 2025.
Abstract Sturgeons are a group of iconic rheophilic fish whose populations worldwide are currently undergoing significant declines. The study investigates the impact of climate change and anthropogenic activities, particularly the Gabčíkovo barrage system, on the survival and distribution of the sterlet, the last surviving sturgeon species in the ...
