Genetic diversity and structure in populations of Piaractus mesopotamicus

Brazilian Journal of Animal and Environmental Research
Inadequate genetic management of broodstock in fish farming can lead to a reduction in genetic diversity, negatively affecting key productive traits such as growth and weight gain. This study evaluated the genetic diversity and population structure of pacu (Piaractus mesopotamicus Holmberg, 1887) from two fish farms located in the states of Bahia and ...

Anesthetic Efficacy and Physiological Response to MS‐222, Eugenol, and Cymbopogon flexuosus Essential Oil in Juvenile Spotted Seatrout (Cynoscion nebulosus)

Aquaculture Research, Volume 2026, Issue 1, 2026.
For aquaculture, animal welfare constitutes a fundamental dimension of sustainability because it directly influences health, productivity, resource efficiency, and the ethical standards of production systems. Spotted seatrout (Cynoscion nebulosus) is a marine fish recognized as an emerging candidate for aquaculture in the Gulf of Mexico and, like other

How Dietary Methionine Shields Golden Pompano (Trachinotus ovatus) From Cold‐Stress Triads via Nrf2 Activation?

Aquaculture Research, Volume 2026, Issue 1, 2026.
This study evaluated the physiological and molecular mechanisms underlying cold stress tolerance in golden pompano (Trachinotus ovatus) after a 56‐day feeding trial with high‐lipid diets (18%) supplemented with varying methionine (Met) levels (1.04%, 1.14%, 1.24%, 1.34%, 1.44%, 1.54%, and 1.64%).
