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 ...

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.
