Resolution of taxonomic problems and preparation of a user-friendly identification guide to whole fish and fillets for South East Fishery "quota species"

An upgraded identification guide to fish and fillets of the South East Fishery (SEF) quota species groups has been compiled from new information. This reference, South East Fishery.Quota Species: an Identification Guide (Daley et al., 1997) and hereafter referred to as SEF Species Guide, was...

AFMA recently announced the completion of amendments to the ETBF management plan, and the call for applications for statutory fishing rights. These fishing rights, and the effort allocation of effort that accompanying them, will be managed using Spatial Area Factors (SAFs). SAFs are multipliers that translate the actual amount of fishing effort expended, e.g. in thousands of hooks, into the amount of effort units that are taken off an SFR holders allocation. The intent of these SAFs is to allow spatial management of the fishery, by providing incentives for fishing in areas with low SAFs and disincentives in areas with high SAFs. If used effectively, these SAFs may provide a mechanism for reducing many of the management conflicts in the fishery, such as catch of seabirds and turtles, local depletion of target stocks, and under-exploitation of high seas areas. However, in order to effectively apply the SAFs, AFMA will need to be able to determine the motivational effect of the SAF on fishermen's location choices. Moreover, the SAFs will affect the total allowable effort (TAE) that is actually realized in the fishery in a given year, so not only will they affect individual fishers, they will also affect the performance of the fishery as a whole. It will be critical to be able to make some predictions about how the realized TAE will change, based on the structure of the SAFs in order to weigh alterative management options prior to implementing them. Finally, a move from TAEs to TACs and ITQs will substantially affect the structure of the fishery. Although we will not directly address those changes in this proposal, the behavioral models developed in this project would be rapidly adaptable to a TAC/ITQ system, and could form a basis for informing management as to the potential effects.

Objectives

1. Develop a statistical (multivariate logit) model to predict the distribution of fishing effort in the ETBF
2. Develop a process (a state-dependent behavioral) model of effort allocation for an input managed fishery with individual effort allocations
3. Evaluate the impact of a series of SAF scenarios on the distribution of fishing effort in the ETBF using statistical and state-dependent behavioral models

Retrospective assessment of ITQs to inform research needs and to improve their future design and performance

The use of transferable fishing rights has increased internationally over recent decades with most industrialised countries now using some form of individual transferable catch quota (ITQ) or individual transferable effort (ITE) system for at least some of their fisheries. Australia also has...

Testing abalone empirical harvest strategies, for setting TACs and associated LMLs, that include the use of novel spatially explicit performance measures

The management of abalone stocks is difficult for many reasons including their high value and the exceptional levels of spatial structuring found in their stocks. In Tasmania, for example, suggestions to change such things as a legal minimum length or introduce a formal harvest strategy to replace...

Maximising net economic returns from a multispecies fishery

Achieving fishery MEY may result in a reduction in net economic returns in a broader sense if the loss to consumers exceeds the gain to the industry. Such a loss may occur if supplies to the local market are reduced and prices paid by consumers increase. This results in a transfer of benefits from...
