Implementation of dynamic reference points and harvest strategies to account for environmentally-driven changes in productivity in Australian fisheries

The need to adapt stock assessment methods and harvest strategies to explicitly and justifiably account for shifts in productivity has been recognised by the AFMA Resource Assessment Group for the Southern and Eastern Scalefish and Shark Fishery (SESSF), not least as a result of clearly evident...

Do commercial fishery data reflect stock status in South Australia's Southern Garfish fisheries?

During the early 2000s, stock assessments highlighted considerable issues with the status of South Australia’s stocks of Southern Garfish (Hyporhamphus melanochir). This led to significant management changes that were implemented in 2005, which included the introduction of new...

Need

The ecological risk assessment process recently undertaken jointly by AFMA and CSIRO has identified that sharks generally, are high priority species which require focussed management attention. In the Southern and Eastern Scalefish and Shark Fishery (SESSF) this is particularly the case for upper slope Southern and Eastern gulper sharks (including Harrison’s dogfish and Southern dogfish) which have been found to be severely depleted and have been nominated as threatened species under the EPBC Act. AFMA is now developing management responses to address these identified ecological risks, and there are a number of complimentary processes currently underway. These include the bycatch working group in the SESSF, which is currently preparing a bycatch work plan to be developed and implemented during 2008. AFMA is also establishing an expert shark and ray (Chondrichthyan) working group to develop appropriate management responses for these species across all fisheries. There is also a small working group in the South East Trawl Fishery (SETF) which is looking closely at the deepwater shark species of the lower slope and additional work is being undertaken to provide immediate management recommendations in relation to Harrison’s dogfish in particular. However, despite these various initiatives, there is a need to review available information on the upper slope gulper sharks (including species other than just Harrison’s dogfish) to improve understanding of levels of interaction and to provide advice on future management options.

Objectives

1. Review the success of management arrangements used elsewhere around the world to address the sustainability of fisheries catches involving similar upper slope low productivity shark species
2. Consider the historical identification of Harrison's dogfish including catch statistics and scientific surveys.
3. Investigate and improve estimates on the extent and nature of actual interactions with Harrison’s dogfish and other similar upper slope gulper sharks in all sectors of Australia’s SESSF
4. Provide an analysis, with supporting rationale, for alternative management options for reducing the ecological risk to Harrison’s dogfish and other similar upper slope gulper sharks in Australia’s SESSF

Indices of recruitment and effective spawning for tiger prawns stocks in the Northern Prawn Fishery

In the mid to late 1980s NORMAC began to suspect that tiger prawn spawning stocks in the NPF may have been reduced by fishing to levels that reduced recruitment to the fishery. A vessel buy-back scheme and other effort reductions were introduced to reverse this trend but, by the mid-1990s, the...

Seafood CRC: Sydney rock oysters: overcoming constraints to commercial scale hatchery and nursery production

Objectives: 1. To establish protocols for improved broodstock conditioning and handling, particularly to permit out-of-season spawning of selected oyster stocks. 2. To determine the effects of the key autecological factors (temperature and salinity) and nutrition on SRO embryos and larvae, to...
