The NPF is one of the Australian Commonwealth’s most valuable fisheries. The species
groups targeted include tiger, banana and endeavour prawns. The fishery is managed using
input controls and, from 2001 until 2004 (the period which spans this study), the agreed
target was for the level of fishing effort expended to lead to a 70% chance (or greater) that
the spawning stock size of tiger prawns was at or above that corresponding to Maximum
Sustainable Yield, SMSY. A key issue in the management of this fishery is that the efficiency
of fishing effort is continually increasing so that past effort reductions have been
fully offset by improved efficiencies. In fact, some past effort reductions did not actually
lead to a real reduction in effective effort. As a consequence of this, there was no recovery
in the size of the tiger prawn resource but rather, in some years, a decline, until a major
effort reduction program was implemented in 2001.
