Mathematical Model to Study the Effect of Refuge on Cannibalism in Atractosteus tropicus

Mathematics
Cannibalism is a behavior that different species of fish exhibit in the early stages of their life, and it has been widely reported. In Tabasco, Mexico, the ancestral species Atractosteus tropicus is farmed, which is a freshwater fish with a high ...

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,

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 Indigenous Probiotic Lactococcus lactis PH3-05 Enhances the Growth, Digestive Physiology, and Gut Microbiota of the Tropical Gar (Atractosteus tropicus) Larvae [PDF]

Animals
Probiotics in aquaculture hold promise for enhancing fish health and growth. Due to their increased specificity and affinity for their host, indigenous probiotics may offer isolated and potentially amplified benefits.

The hepatopancreas microbiome of velvet crab, Necora puber. [PDF]

Environ Microbiol Rep
We 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 Nutr
The 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 ...

Cardiorespiratory physiological phenotypic plasticity in developing air-breathing anabantid fishes (Betta splendens and Trichopodus trichopterus). [PDF]

Physiol Rep, 2017
Developmental plasticity of cardiorespiratory physiology was determined in two air‐breathing anabantid fishes (Betta splendens and Trichopodus trichopterus) by chronic rearing in nocturnal hypoxia. Hypoxic rearing increased hypoxic tolerance in Betta, which inhabits temporary ponds with nocturnal hypoxia.
