Abstract
The Southern rock lobster, Jasus edwardsii, is a temperate species of spiny lobster with established well
managed fisheries in Australia and New Zealand. It has also been under consideration as a species with
aquaculture potential. Agonistic behaviour has important consequences under aquaculture conditions that
encompass direct effects, such as damage or death of protagonists, and indirect effects on growth that relate
to resource access, principally food and refuge. This study aimed to identify and characterize behaviours and
to make a preliminary investigation of their occurrence under tank culture. Juvenile Jasus edwardsii were
examined in a flow-through seawater system using a remote video camera system. Twenty-nine behaviours
were divided into three sub-groups: aggressive (11), avoidance (6) and others (12). Aggressive behaviours
included attacks, pushing, lifting, clasping and carrying an opponent. Avoidance behaviours included moving
away in a backwards-, forwards- or side-stepping motion as well as with more vigorous tail flips. These
behaviours were components of twelve behavioural groups that described contact, attack and displacement
between individuals. Activity was crepuscular with two clear peaks, one in the morning and the other in
the evening. The occurrence of behavioural groups was not different between the morning and evening.
The frequency of aggressive behaviours was not affected by changes made to stocking density or access to
food. The implications of agonistic behaviours are discussed further in relation to developing aquaculture.
