Abstract


Shark depredation, where sharks consume hooked fish, occurs in recreational fisheries in Western Australia. This thesis recorded a shark depredation rate of -12% in the Ningaloo region, and identified variables correlating its occurrence. Four shark species were identified to be responsible for depredation. Travel cost significantly impacted fisher site choice, although catch rate and depredation rate had little influence. Mitigation strategies are needed to reduce target species mortality and loss of fishing gear and improve the recreational fishing experience. This thesis provides the first investigation of shark depredation in an Australian recreational fishery, generating important information for fisheries management.
