Management strategies for an inputcontrolled fishery based on the capture ofshort-lived tropical species : the example ofAustralia’s northern prawn fishery
2006
Dichmont, CM
The NPF is one of the Australian Commonwealth’s most valuable fisheries. The speciesgroups targeted include tiger, banana and endeavour prawns. The fishery is managed usinginput controls and, from 2001 until 2004 (the period which spans this study), the agreedtarget was for the level of fishing effort expended to lead to a 70% chance (or greater) thatthe spawning stock size of tiger prawns was at or above that corresponding to MaximumSustainable Yield, SMSY. A key issue in the management of this fishery is that the efficiencyof fishing effort is continually increasing so that past effort reductions have beenfully offset by improved efficiencies. In fact, some past effort reductions did not actuallylead to a real reduction in effective effort. As a consequence of this, there was no recoveryin the size of the tiger prawn resource but rather, in some years, a decline, until a majoreffort reduction program was implemented in 2001.
