Need

Ministerial recommendations following Strategic Assessment of the SESSF Trawl Fishery were that:

18. AFMA, in consultation with industry, EA, researchers and other stakeholders, to further assess and reduce the extent of interactions of seals, cetaceans and seabirds across all sectors of the SESSF, and interactions with syngnathids in the trawl sectors and white sharks in the gillnet and hook sector. AFMA will, for all of the above species:
• within 12 months, establish robust data collection and reporting systems to quantify the extent of interactions; and
• within 3 years assess, trial and implement as appropriate mitigation or avoidance measures including further trials of bycatch exclusion devices and spatial or temporal closures.

For seals and sea lions, AFMA will, within 18 months, extend across the trawl sectors management measures assessed as effective to help reduce interactions with seals and sea lions.

By the time you are considering whether to fund this project, the December 2004 deadline for establishment of the robust data collection and reporting system will have passed.

ISMP observer trips only cover 5% of trawl shots, so there is a lot of uncertainty about relatively rare events such as the interactions of trawl vessels with seals. Power analysis of the ISMP data revealed that to detect even a 50% decrease in the interactions with seals would require an observer program more than 7 times the current level of coverage. This would be likely to cost industry over $4 million dollars annually. If even half of industry accurately recorded their interactions with seals, it would provide a level of monitoring of this issue that would be ten times more powerful than the current ISMP coverage at a cost of 2% of independent observer coverage.

Industry can not afford to do anything other than immediately establish its own program to monitor the interactions of trawl vessels with seals. The current ISMP will be used to audit the industry-based monitoring program.

Objectives

1. To provide fishers with relevant information on the biology and conservation of seals to help raise industry awareness and encourage increased reporting of seal-fishery interactions.
2. To ensure that Industry is familiar with and applies its Code of Conduct especially in relation to the mitigation of incidental seal bycatch and seal mortality.
3. To establish a robust industry-based monitoring program that provides spatial and temporal information on the level of seal-fishery interactions of SESSF trawl vessels.
4. To develop and trial options to validate the robustness/reasonableness of the data collection and reporting system to quantify the extent of seal interactions and report on the potential uptake by fishers of each option and the extent of effectiveness of each option in meeting the relevant strategic assessment requirements of the EPBC Act.

Need

Environmental and fisheries managers urgently need reliable data to underpin strategies to conserve or improve the ecosystems of normally-closed estuaries in the central region of the south coast of Western Australia. These managers thus need:

1. An understanding of the current status of the fish fauna of the highly-degraded Culham Inlet, and particularly of its population of black bream, and how that status has been influenced by extreme environmental perturbations in the recent past.

2. Reliable information on the extent to which the extreme environmental conditions experienced in certain of the last ten to fifteen years influenced either the spawning success and/or survival of the 0+ age class of black bream in Culham Inlet.

3. An understanding of the current status of the fish fauna of Stokes Inlet, which is less degraded than Culham Inlet but is still the subject of concern for local residents and visitors, and of Hamersley Inlet in whose catchment the vegetation has been the subject of only a relatively low level of clearing.

4. An ability to predict, qualitatively, the extent to which continuing degradation of any normally-closed estuary in the central region of the south coast of Western Australia will affect the fish faunas of those estuaries and, in particular, their recreational and commercial fish species. This information is required by the Department of Fisheries WA for developing its overall plan for managing the recreational and commercial fisheries in these estuaries (R. Lenanton, pers. comm.) and by other governmental authorities for developing strategies for conserving or restoring the quality of the important environments afforded by these estuaries.

Objectives

1. Determine, on a seasonal basis, the compositions of the fish fauna of the basin and riverine regions of Culham, Stokes and Hamersley inlets and ascertain whether pools upstream act as a refuge for black bream.
2. Relate any differences in the compositions of the fish faunas in the three estuaries to differences in the environmental characteristics within and between these estuaries, and in particular of salinity, dissolved oxygen and water levels.
3. Use age composition data to determine the variations in annual recruitment of black bream in Culham, Stokes and Hamersley inlets in recent years, and relate these to environmental conditions, and particularly to the relative estimated strength of freshwater discharge and whether or not the bar at the estuary mouth had been breached.
4. Compare the growth rates of black bream in the three estuaries and relate any differences that are detected to the environmental conditions that are experienced within each system.
5. Provide to environmental and fisheries managers an assessment of the levels at which salinity and dissolved oxygen influence the abundance of the main fish species and how those critical levels vary amongst those species

Genetic analysis of the spatial structure of SBT population

Project number: 1992-031
Project Status:
Completed
Budget expenditure: $148,967.00
Principal Investigator: Peter Grewe
Organisation: CSIRO Oceans and Atmosphere Hobart
Project start/end date: 26 Sep 1992 - 5 Dec 1995
Contact:
FRDC

Objectives

1. To assess the genetic variability in juvenile SBT collected from the SW coast of Australian adults collected off S Africa and adults collected from the east coast of Tasmania
2. The genetic variation present among the sample locations will be used to test the hypothesis that the two length modes present in a single year class of juvenile SBT relate to at least two genetically different components of the population.
3. Genetic variation between the African and Tasmanian adult samples will help determine whether genetic differences observed in juvenile fish is related to their spatial distribution as adults
