Abstract
The combined effect(s) of holding temperature and claw immobilisation (nicking) on Cancer pagurus were investigated. Creel captured animals (n = 48) were maintained at 4 °C, 8 °C and 12 °C for 14 days in order to mimic environmental conditions in commercial holding facilities. The consequences of nicking on animal health were assessed by measuring physiological and immune-related parameters in the haemolymph: total protein concentration, l-lactate, pH, haemocyte counts and phenoloxidase activities. Mortality was most severe in nicked crabs held at 12 °C (83%) compared to non-nicked crabs held at the same temperature (16.7%) or nicked crabs held at lower temperatures (16.7% at 8 °C and 0% at 4 °C). Stress-related parameters such as l-lactate and pH were only affected in the most extreme condition (crabs nicked at 12 °C). However, phenoloxidase activities increased significantly (even in control groups) with increasing temperature, an effect that was exacerbated by the nicking process.
