Handling time and predation behaviour by the crab, Cancer pagurus, preying on cultured scallop, Pecten maximus

摘要: We investigated handling time, persistence time and shell-breaking techniques by crab, Cancer pagurus (L.) (13-15 cm carapace width), offered cultured scallops, Pecten maximus(L.), within the recommended release size for bottom culture. Three shell height groups were used: 50-55, 60-65 70-75 mm. The results showed that crabs managed to open scallops from all three groups. median in 50-55 mm group (788 s) was significantly different of (2482 (2980 increased with each scallop size, 89 s 97 125 group. observed a change dominance smashed more punched chipped shift predation behaviour when compared larger is discussed relation strategies seabed cultures.
