Abstract:
American lobsters are crustaceans that are offered for sale live and are stored in controlled temperature recirculating aquaria. During their marketing they are subjected to stressors that can affect their welfare, such as air exposure, confinement and handling. European legislation does not provide specific criteria or retention requirements, and so their management depends largely on the common sense of food business operators. Claw ligatures before and during storage are not legally required but are recommended because they prevent lobsters from damaging each other and ensure workers’ safety. The aim of the present study is to evaluate the effect of claw ligatures on lobsters’ welfare by analysing eight different haemolymph stress parameters, vitality and weight. The calcium level showed statistical differences in the two experimental groups (P < 0.05). Our results suggested that the absence of rubber bands did not offer any significant contribution to the lobsters’ welfare.
