The southern rock lobster (Jasus edwardsit) is fished commercially in south-eastern Australia and New Zealand. The Victorian annual catch is currently 458 tonnes with a landed value of $14.5 million representing 10.6% of total rock lobster landings in south east Australia (ABARE 1997). Over eighty...
Management of the valuable Australian abalone fishery is difficult because catch/effort information for abalone does not provide warnings of declining stocks. In fact abalone fisheries in Alaska, California and Mexico have collapsed or declined dramatically, with little warning. Management must rely...
Tagging is an important tool for estimating key fisheries parameters such as fishing mortality, natural mortality and growth. This project identified the need for future tagging projects to undertake preliminary studies to determine the impact of tagging on both growth and survival, and we developed...
Several critically important steps to achieving the central long-term aim of this project namely, cost-effective enhancement of abalone fisheries using hatchery produced seed stock, were achieved. The first was year-round controlled temperature conditioning and spawning of captive broodstock. This...

In September 1995, the deepwater trawl fishing industry agreed not to trawl in an area of 370 km2 on the continental slope south of Tasmania for three years, as stated in a Memorandum of Understanding between the former Australian Nature Conservation Agency (now Environment Australia) (EA) and the...
A sampling method was developed to quantify changes in the abundance of abalone on reefs in NSW from Port Stephens to the Victorian border. The method is based on the repeated sampling of the same, fixed areas and has been used each year since 1994 to provide indices of the relative abundance of...

The pearling industry is Australia’s most valuable aquaculture industry, generating approximately $187 million in 1997 (source: ABARE 1997). The oysters used to culture pearls are derived almost entirely from wild stock shell, rather than hatchery produced stock as occurs in other major...
