Concerns about declining stock and profitability in the Tasmanian rock
lobster industry led to the introduction of individual transferable quota
(ITQ) management in 1998. In this study, fisher groups were categorised
by effort and quota ownership traits to examine response to revised
management, and how profit drivers moderated this change....
ITQ introduction has had several effects on fisheries in terms of, for
example, changes in the composition of the fishing fleet and fishing
efficiency gains. After ITQ introduction in the Tasmanian rock lobster
industry in 1998, an increasing number of fishers have become dependent
on quota leasing to catch fish...
Considerable attention has been applied to the development of models explaining how fish stocks change over space
and time, from relatively simple stock-recruitment relationships to ecosystem models with a complex food web
structure. However, in many case studies fishing effort is assumed to be exogenous and even in dynamic models...
