Need

There is an immediate and strategic need for the CCSBT to agree to an MP to guide the global catch setting to ensure the rebuilding of the SBT stock. For this to occur, an MP needs to be developed and agreed by the CCSBT; failure to do so will result in the global catch of SBT being reduced to 5000-6000 t, with a subsequent significant impact on the Australian SBT fishery. Australia in collaboration with Japanese and other CCSBT member scientists are responsible for the development and evaluation of the MP, which in the context of a Regional Fisheries Management Organisation (RFMO), such as CCSBT, is a unique and innovative concept that will establish a rebuilding pathway for the stock. Having a rebuilding strategy that has been rigorously and openly tested, is robust to the key fishery-specific issues and uncertainties, and establishes a process whereby decisions will be made and enforced will be a first in the tuna RFMO milieu.

As an effective recovery plan for SBT can only exist at the international level (given the shared nature of the resource) the development and adoption of the MP work can also be interpreted as a direct requirement of the current conservation dependent status of the stock. It is therefore essential to complete the MP development work for adoption by the Commission in 2011.

Objectives

1. Development of candidate management procedures, within the CCSBT international collaborative scientific structure, to guide the recovery of Southern bluefin tuna
2. Define and compute a set of reference points for evaluating the performance of the MPs and the risk status of the stock that are consistent with both the rebuilding criteria and the underlying models used to evaluate the MPs themselves

Biological data for the management of competing commercial and recreational fisheries for King George whiting and black bream

Both the King George whiting and the Black bream are important commercial and recreational finfish species in south-western Australia. The fisheries for Black bream are restricted to estuaries, whereas the King George whiting recreational fisheries is based in both estuaries and protected...

Assessment of Queensland inshore net fisheries

Most of the world’s marine fish harvest still comes from coastal waters despite the rapid development of distant water fishing fleets (McHugh, 1967). Fish yields from estuaries and lagoons are generally high, due to factors including shallowness, inflow of nutrients from rivers, and the...

Assessment of optimal trapping techniques to control densities of northern Pacific seastars on marine farm leases

The principal aims of this study were to evaluate whether the locally­ produced Whayman-Holdsworth trap provides an effective method for minimising Asterias amurensis infestations on shellfish farms, and to objectively assess the value of seastar traps when used in commercial applications. In an...
