Sub-lethal behavioural and physiological responses to an underwater explosion in two crustacean species.

The impacts of a small, free-field, surface explosion from a ship scuttling, on two crustacean species was examined. The southern rock lobster (Jasus edwardsii) and the spotted shore crab (Paragrapsus gaimardii) were used to compare the effects on crustaceans in a controlled experiment on animals distributed up to 500 m from the blasts. Methods for assessing damage included; mortality, behavioural experiments, and physiological assessments.
