Abstract
The losses to the western rock lobster fishery through the predation of pot-caught rock lobsters by octopus were estimated from samples taken on commercial boats in the four seasons 1972/73 - 1975/76. In most seasons approximately 200 000 legal-sized rock lobsters were lost. In the 1975/76 season the estimated financial loss from octopus predation was $392 000. The estimated losses probably represent minimum values. Studies of the biology and behaviour of octopus were carried out to examine the methods of detection, location and entry into rock lobster pots by octopus. The use of octopus traps in rock lobster pots significantly increased the catch of octopus from rock lobster pots without any significant effect on rock lobster catches.
