  • Catches per trap of lobsters (Homarus americanus) and rock crabs (Cancer irroratus) were compared to densities of each species measured by divers. Trapping and diver surveys were carried out in habitats with and without macroalgae. Catchability coefficients (catch per trap/animal density) increased greatly with animal size. For example, in a habitat with macroalgae catchabilities were 13, 47, and 492 m2∙trap−1 for lobsters of 50–59, 60–69, and 70–89 mm carapace length, respectively. For crabs… CONTINUE READING
