The blue crab, Callinectes sapidus Rathbun, 1896, which is a commercially important trophic link in coastal ecosystems of the western Atlantic, is infected in both North and South America by C. sapidus Reovirus 1 (CsRV1), a double stranded RNA virus. The 12 genome segments of a North American strain of CsRV1 were sequenced using Ion Torrent technology. Putative functions could be assigned for 3...

Predators control prey abundance and behavior, both of which strongly influence community dynamics. However, the relative importance these predator effects may shift with climate change stressors, suggesting understanding potential on different processes is critical to predicting function. We investigated global warming ocean acidification transmission detection chemical cues from blue crab pre...

• Low salinity is new used in mud crab culture to expand the inland saline aquaculture. Dietary lipid source, but not salinity, influenced nutritional values of flesh crab. changed myofiber structure and provided texture for consumers. dietary soybean oil weakened umami taste aroma flesh. The quality crustaceans’ has direct impact on consumers’ purchase choices, with water environment nutrition...

Worms and other marine invertebrates living in soft sediments commonly produce brominated natural products that have been hypothesized to function as defenses against consumers, but this hypothesis has not been tested directly. When 16 species of worms from a Georgia mud flat were fed to two sympatric fishes (Fundulus heteroclitus, Leiostomus xanthurus) and a crab (Callinectes similis), 15 spec...

Mud crab ( Scylla paramamosain ) fed five different diets with varying concentrations of guava leaf aqueous extract (0 mg·kg –1 , 80 160 320 and 640 for 30 days. crabs in the guava-leaf groups outperformed control group terms survival rates (SR), weight gain (WGR), specific growth (SGR). When compared to group, mud had significantly higher levels lipase (LPS), pepsin, lysozyme (LZM), superoxide...
