Difference in nutritional status and food sources for hard- and soft-shell crabs (Portunus trituberculatus) using amino acids and isotopic tracers

Difference in nutritional status and food sources for hard- and soft-shell crabs (Portunus trituberculatus) using amino acids and isotopic tracers

Abstract The swimming crab, Portunus trituberculatus, supports the world’s largest crab fishery. Hard-shell crabs have fully developed exoskeletons and are rich in meat, while soft-shell crabs, which have recently molted, contain less meat. To determine their nutritional status and feeding behavior,...
