Bibliography: leaves 102-106. "The study investigates South Australian (SA) commercial fisheries and aquaculture operations and seal interactions by exploring perceptions in the commercial fishing industry and comparing them to 2nd Century fishers experiences. The results confirm that SA commercial fishers do interact with seals and that interactins with Australian Sea Lions may be disproportionately more than with New Zealand Fur Seals. While some commercial fishers experience is similar to 2nd Century fishers and consider interference by seals to be major hindrance and suggest culling for management of seals, in general, SA commercial fishers are open to mitigation initiatives including gear modifications, to address seal interactions. The dissertation also examines some management mitigation options to minimizing fisheries-seal interactions and offers recommendations." -- ABSTRACT
