Improvement of Fish Growth and Metabolism by Oligosaccharide Prebiotic Supplement. [PDF]
Aquac Nutr, 2022 Finfish aquaculture is expected to continue to benefit from significantly improved fish diets, which are the source of energy to support the growth and health of fish. Strategies to enhance the transformation rate of dietary energy and protein to fish growth are greatly desired by fish culturists. Prebiotic compounds can be used as supplements to human,

Developmental cardiorespiratory physiology of the air-breathing tropical gar,Atractosteus tropicus [PDF]
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2016 The physiological transition to aerial breathing in larval air-breathing fishes is poorly understood. We investigated gill ventilation frequency ( fG), heart rate ( fH), and air breathing frequency ( fAB) as a function of development, activity, hypoxia, and temperature in embryos/larvae from day (D) 2.5 to D30 posthatch of the tropical gar ...

Early Mild Stress along with Lipid Improves the Stress Responsiveness of Oscar (Astronotus ocellatus). [PDF]
Aquac Nutr, 2022 Early‐life exposure to mild stressors can assist animals in coping with more stressful events in later life. This study was aimed at investigating how early stress and dietary lipid contents affect growth, hematology, blood biochemistry, immunological responses, antioxidant system, liver enzymes, and stress responses of oscar (Astronotus ocellatus) (6 ...

The hepatopancreas microbiome of velvet crab, Necora puber. [PDF]
Environ Microbiol RepWe provide the first description of the hepatopancreas microbiome of the velvet crab, Necora puber, identifying a microbial community dominated by Candidatus hepatoplasma and the presence of a core microbiome. We also investigate the variation explained by our study factors: crab sex, parasite infection status, and two different sampling time points ...

Changes in Digestive Enzyme Activities during Larval Development of Spotted Seatrout (Cynoscion nebulosus). [PDF]
Aquac NutrThe spotted seatrout (Cynoscion nebulosus)—an important commercial species—has a high potential for aquaculture in the Gulf of Mexico. To optimize its feeding during larval rearing, this study aims to evaluate the primary gastric (pepsin), intestinal (leucine aminopeptidase and alkaline phosphatase), and pancreatic (alkaline protease, trypsin ...
