Aquatic Animal Health Subprogram: Identifying the cause of Oyster Oedema Disease (OOD) in pearl oysters (Pinctada maxima), and developing diagnostic tests for OOD

The goal of this project was to investigate the cause of oyster oedema disease (OOD) in Australian pearl oysters so that diagnostic tests and management practices for the disease can be developed. OOD has been associated with mortalities in some pearl oyster farming areas. However, the cause of...

Study of ghost fishing in the NSW rock lobster fishery

This project concerns an assessment of the significance ghost fishing in the NSW Rock Lobster Fishery and potential modifications to fishing gears and practices that could minimise trap loss and consequent ghost fishing of the target species, Eastern Rock Lobster, Sagmariasus verreauxi. The...

Understanding recruitment variation (including the collapse) of Saucer Scallop stocks in Western Australia and assessing the feasibility of assisted recovery measures for improved management in a changing environment

This study examined possible contributing environmental factors to the recruitment variability of the Ballot’s saucer scallop Ylistrum balloti across the main stocks in Western Australia. The project was undertaken to explain the variation observed between years and between regions as well...

Spawning biomass of Jack Mackerel (Trachurus declivis) in the East sub-area of the Small Pelagic Fishery during summer 2019

Estimates of spawning biomass obtained using the Daily Egg Production Method (DEPM) are the primary biological performance indicator for quota species in the Small Pelagic Fishery (SPF). The objective of this study was to conduct ichthyoplankton and adult trawl surveys that underpin the DEPM in the...

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...

An industry based mark recapture program to provide stock assessment inputs for the Western Rock Lobster Fishery following introduction of quota management

The West Coast Lobster Managed Fishery (WCRLMF) moved from input to output controls in 2010. This change directly affected the relativity of a number of fisherybased data sources, making assessment of the fishery more problematic. A novel examination of the stock dynamics was required to help ensure...

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)...
