Abstract Blue swimming crab (Portunus pelagicus) is one of Indonesia's highest-export fishery commodities. Capture fisheries are dominated by fishermen with low productivity, efficiency, and income levels. There a high-profit disparity between upstream downstream actors, where get the lowest profit. This study aims to identify causes profit disparities supply chain actors propose model solve pr...

Interannual variability in the abundances of blue crab (Callinectes sapidus) in populations along the U.S. east coast is well documented, but the mechanisms driving these fluctuations remain poorly understood. Using principal component analysis and dynamic factor analysis we quantified the patterns in variability and the degree of synchrony among blue crab populations along the U.S. east coast ...

Content of mercury in hepatopancreas, muscle and exoskeleton of blue crab T. prymna from Musa estuary and their relationship with size of the organism and season were determined. Mean concentration of mercury in hepatopancreas, muscle and exoskeleton were 1.23, 0.61 and 0.41 µg/g dw, respectively. There was significant difference (p<0.05) in mercury levels depending on the sex with greater ...

Abstract The food habits of the blue swimming crab, Portunus segnis (Forskål, 1775) were investigated using specimens collected from trawl catches in north-east Persian Gulf, June 2018 to May 2019. Feeding 304 adult female crabs, ranging 2.6 8.7 cm carapace length, analysed. stomach content examined crabs showed consist crustaceans, fish, molluscs, unidentifiable material, sea grass and foramin...

Meatballs made from fishery products such as fish, shrimp, and squid are among the popular street foods in Asia. To meet increasing demand for these foods, there is a need to develop/formulate new balls out of products. Hence, this study, crab blue swimming crabs (Portunus pelagicus) were formulated standardized using three formulations (meat binder ratio): Formulation A (50:50), B (60:40), C (...

Although multiple predator effects and trophic cascades have both been demonstrated in a wide variety of ecosystems, ecologists have yet to incorporate these studies into an experimental framework that also manipulates a common and likely important factor, spatial heterogeneity. We manipulated habitat complexity, the presence of two top predators (toadfish and blue crabs), and one intermediate ...
