Summary

This project found and described a baculovirus similar to Monodon Baculovirus (MBV) that was called Plebejus Baculovirus (PBV) as it was in eastern king prawns (Penaeus plebejus). It later found it in Australian cultured Penaeus monodon.

The project investigated other conditions, particularly Hepatopancreatic Parvolike Virus (HPV) and Shann Bodies. Results were published in the scientific literature and presented at industry meetings. It was recommended that prawns be screened for the known virus infections in Australian prawns by subsamples of 25 prawns examined in H. and E. sections without stressing prawns for viral enhancement. Prawns were screened to be moved interstate for the governments of Queensland, New South Wales, Victoria, Western Australia and the Northern Territory, and many examinations were carried out for individual prawn farmers. 4 papers and 7 reviews on prawn diseases were published.

Summary

The large starfish, Coscinasterias calamaria is known to feed on commercially exploited molluscs, including blacklip abalone (Haliotis rubra), mussels (Mytilus edulis) and scallops (Pecten irradians).

The study investigated the abundance of the seastar on reefs in Port Phillip Bay, and the extent to which it reduces stocks of the blacklip abalone on these reefs. It is recommended that abalone divers note when there appear to be very few small mussels on offshore reefs early in the year, as this may provide a warning of possible depletion of abalone stocks later. Preventative measures could then be taken.

Northern shark tagging study

In 1982, CSIRO applied to the Fishing Industry Research Trust Account for funding of a joint biological investigation of northern Australian pelagic fish stocks. At that time these stocks supported a Taiwanese surface gill-net fishery based on sharks, tunas and Spanish mackerel. During the 1970's...
