Opportunities and impacts of range extending scalefish species: understanding population dynamics, ecosystem impacts and management needs

This work set out to quantify the biology and diet of three key range-shifting species in Tasmania with both recreational and commercial fishery value. The project was heavily reliant on engagement from the recreational fishing community and multiple citizen science initiatives, as well as...

Application of tracking technologies to understand space-time explicit patterns of movement, residency and habitat use of pelagic sharks in Spencer Gulf: resolving overlaps with key community activities and marine industries

The report focuses on the movement dynamics of two pelagic sharks, the White Shark (Carcharadon carcharias) and Bronze Whaler (Carcharinhus brachyurus), in South Australia. Specific aims were to: (1) determine if aquaculture activities correlated with patterns on fidelity and migration; and (2)...

Developing a fishery independent estimate of biomass for snapper

This study was undertaken by the South Australia Research and Development Institute (SARDI). Through overcoming considerable technical challenges, this study was the first to successfully develop a relatively non-destructive molecular probe that can reliably identify Snapper (Chrysophrys auratus)...

Need

A systematic program of research and development is needed to enable reliable cost-effective hatchery production of Sydney rock oyster (SRO) seed to allow demonstrated benefits of triploid oysters and advances in SRO selection for growth and disease resistance. This R&D program incorporates relevant recommendations of the recent “Review of Hatchery Production Technology and Breeding Program for Sydney Rock Oysters (“Benzie et al., FRDC 2001/213). This review acknowledged that the potential benefits of solving SRO hatchery production problems far outweigh the likely costs. The R&D program also incorporates and integrates recommendations the of the NSW Fisheries – FRDC “Sydney Rock Oyster Hatchery and Nursery Health Workshop” held on the 8 th and 9th of August 2002 at Nelson Bay. Central among these recommendations were:
1 The need for a revision of hatchery procedures and the assessment/adoption of alternate algal, larval and spat rearing technology.
2 The need to elucidate the fundamental autecological (temperature and salinity) and nutritional requirements of SRO during early ontogeny, that have not yet been addressed and will be central to the production of the species.
3 The need for systematic and appropriate sampling procedures for the diagnosis of potential disease occurrences.

Independent of the species involved, there is a need to document the processes involved in developing techniques and strategies to culture otherwise intransigent species. This research will provide a unique opportunity to document the history of problems with SRO, the consultation undertaken, the strategies developed for SRO and the techniques for their implementation. This document, the FRDC final report for this research, would provide a reference for dealing systematically with hatchery based problems and will provide an array of monitoring and assessment protocols for other molluscs.

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 evaluate early larval survival and late larval growth in commercial hatcheries.
3. To trial economical, low cost alternative techniques for algal and larval and spat rearing to enhance commercial SRO production. In particular to establish alternative approaches for spat rearing including spat bubblers and field based nursery systems.
4. To systematically assess the major potential pathogenic or toxic factors that might contribute to larval and spat mortality.
5. To facilitate the establishment of a reliable commercial source of genetically improved SRO spat.

Summary

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 elevate early larval survival and late larval growth in commercial hatcheries.
  • 3. To trial economical, low cost alternative techniques for algal and larval and spat rearing to enhance commercial SRO production. In particular to establish alternative approaches for spat rearing including spat bubblers and field based nursery systems.
  • 4. To systematically assess and monitor the major potential pathogenic factors that might contribute to spat mortality.
  • 5. To facilitate the establishment of a reliable commercial source of genetically improved SRO spat.
  • As a function of the early success of this program in overcoming hatchery production problems, two additional milestones were added with the objective:

  • 6. To assess the performance of selectively bred oysters at seven sites across NSW and then monitor the changes in physiological and reproductive condition of those oysters at 3 of those sites.

    Need

    Research has found that fishers are subject to a multitude of stressors, including those relating to government policies and co-management challenges, a fluctuating market place, crew cohesion and on-shore social relationships, and the pressures of working in a dangerous workplace. Compounding the well-known physical dangers associated with the fishing industry, these factors all place pressure on fisher mental wellbeing, which in turn contributes to issues such as clinically diagnosed anxiety disorders, poor eating habits and substance abuse, eg, evidence from around the world suggests that the particular stresses of fishing contribute to higher than average rates of smoking among fishers.
    Findings from the RIRDC-funded project Staying Healthy: Behaviours and services used by farmers and fishers indicate that while participants from certain farming industry areas have benefited from industry involvement in health and wellbeing, including in relation to mental health, fishers are less likely to report that industry associations have helped them access health and wellbeing information or programs. Some farmers described significant lifestyle changes after participating in programs that were promoted, sponsored or facilitated by trusted industry organisations. As well, recent research (Brooks, 2011, Health and Safety in the Australian Fishing Industry, RIRDC, Canberra) has found a lack of awareness of occupational health and safety among fishers. The Research Audit of Social Sciences Fisheries Research (Clarke, 2009) noted research findings that social wellbeing is related to financial wellbeing, and that social networking is negatively affected by working hours, suggesting a place for an industry specific approach to social connection and mental health. There appears to be a broking role for industry groups and organisations in enhancing the health of the fishing workforce. This project will identify strategies for industry and fishing community organisations to take on this role in effective, but cost and resource efficient, ways.

    Objectives

    1. to explore how industry supports fisher physical health and mental wellbeing
    2. to develop and trial a set of case studies and best practice guidelines for industry organisations in enhancing fisher health and wellbeing in collaboration with industry, fishing communities and health stakeholders
    3. to evaluate the case studies and best practice guidelines
