An international review of the Northern Prawn Fishery tiger prawn assessment was carried out in 2001. The review drew attention to the high level of uncertainty in the assessment and recommended that the logbook data be augmented by fishery-independent survey data. In response to the review,...
The management and disposal of solid wastes from seafood processing, food manufacturing and allied industries is a major economic and environmental issue for Australian industry. Large quantities of wet waste of this nature are routinely disposed of to landfill at considerable cost to...
The Quantitative Training Unit for Fisheries (QTUF) operated at The University of Sydney from 1995 to 2001. There were two distinct phases to the project: Phase I (Project 93/117, from 1995 to 1997) and Phase II (Project 98/348, 1998 to 2001). The QTUF project was designed to address the need for...
The project ‘Age Validation from Tagged School and Gummy Sharks Injected with Oxytetracycline’ (FRDC Project 97/110) follows on from four successfully completed projects. These are the ‘Southern Shark Age Validation’ (FRDC Project 91/037), ‘Southern Shark Nursery’...
Over the past three decades the Tasmanian Eastern Zone Abalone Fishery has experienced several fluctuations in catch and catch rates of Blacklip Abalone as well as environmental perturbations, which may be affecting productivity. The capacity to measure inter-annual variation in Blacklip Abalone...
Measurement of stable isotope ratios of oxygen (18O:16O) and carbon (13C:12C) in the earstone (sagittal otolith) carbonate from assemblages of goldband snapper, Pristipomoides multidens, from waters off northern and western Australia revealed location-specific signatures and indicated that fish...

The origins of many stocks of fish are unknown. As juveniles, many fish are found in estuarine regions. After a period in these habitats they may leave estuaries for coastal reefs and shelf waters where they may be commercially fished. Currently, we do not know the proportion of...
Three acoustic surveys were carried out between 17 and 20 July 1996 on the orange roughy spawning ground off St. Helens, Tasmania. A combination of 22 demersal trawls and ensonification with three frequencies (12, 38 and 120 kHz) was used to assess the species composition around the spawning hill....
