Abalone population dynamics studies and reef area estimation

Most Australian abalone fisheries are fully exploited and a comparison of the total catch of blacklip abalone, Haliotis ruber, in the three south-eastern states indicates a decline in population size from south to north. The catch distribution from New South Wales parallels that trend. This decline...

Ballast water investigations

Ships' ballast water was sampled on 28 occasions in four ports between November, 1976, and October, 1978. A 100.,u plankton net was hand hauled vertically 5 times in each tank. Eight non indigenous species were obtained: 6 copepods, 1 mysid and 1 amphipod. A further 14 species of...

Improving prawn hatchery production by reducing losses due to bacterial disease

Bacterial necrosis was the only bacterial disease syndrome seen during monitoring of 8 larval production runs at 2 commercial hatcheries during the study. Results indicated a possible causal relationship between concentrations of one or more components of the "presumptive Vibrio" populations in...

Evaluation of hatchery production of scallop Pecten fumatas

This project was prompted by poor or variable availability of wild commercial scallop spat for fisheries enhancement and farming in southern Australia and by generally poor and variable success of commercial oyster hatcheries in earlier attempts to fill this shortfall. Scallops from Jervis Bay,...

Evaluating of the role of direct fish-to-fish contact on horizontal transmission of Koi herpesvirus

Epidemiological modelling has been undertaken to evaluate the impact of CyHV-3 as part of an assessment of the feasibility of this virus as a potential biocontrol for carp in Australia. The present project provides information to support key components of the mechanisms of virus transmission which...
