There currently is concern in SRL fisheries about the status of inshore stocks. Catch has declined in a number of areas, despite improvements in catch rates. For example, in Northeastern Tasmania, catch is at record lows, yet CPUE has failed to climb. Inshore stocks on western Tasmania are now receiving historically high levels of effort, due in part to change in shot rotation practices. Further, it is unclear whether the extra effort in these practices is adequately recorded in estimates of CPUE. There has been a recent increase in potting effort, commonly referred to as double night fishing, whereby fishers set and haul their pots twice a night, compared to the standard practice of emptying pots once at dusk and/or once during the day. Currently we have no data on the composition of the catch in double night shots, and what proportion of captured lobsters are handled and released, and what consequence this handling has on production from the fishery.
The specific aim of this thesis was to assess the effectiveness of individual transferable quota (ITQ) systems of management in meeting economic, ecological and social objective(s) through quantitatively analysing changing fishing practices and behaviour of fishers in the Tasmanian Southern Rocklobst
