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.

The numbers of selected parasite species from 23 samples of gemfish, Rexea solandri, from seven locations off southern Australia are given. The data were examined for evidence of isolated gemfish populations. Canonical multivariate analyses of the numbers of larval nematodes (Anisakis spp. and Terranova sp.), larval cestodes (Hepatoxylon trichiurid and Nybelinia sp.), acanthocephalans (Rhadinorhynchus sp. and Corynosoma sp.), and a hemiuroid digenean from a total of763 gemfish showed that the parasite faunas of fish from eastern Australia were similar except for a sample taken off New South Wales at the end of the spawning season whose affinities are unknown.

Fish from South Australia had similar parasite faunas to those collected from eastern Australia suggesting the eastern and western Bass Strait fish belong to the same stock. Samples collected from the Great Australian Bight were distinct from the southern and eastern fish. Differences in parasite fauna were detected between samples taken within the spawning season and those taken from the same locations outside the spawning season, presumably a result of the spawning migration.

Orange roughy are a relatively sedentary species with little movement between fish management zones. This is the conclusion of our analysis of the numbers of parasites in the gut wall of 1251 orange roughy Hoplostethus atlanticus from eight areas off southern Australia and three areas off New Zealand.

Differences in parasite fauna were detected between samples taken within the spawning season and those taken from the same locations outside the spawning season, presumably a result of the spawning migration.

Orange roughy are a relatively sedentary species with little movement between fish management zones. This is the conclusion of our analysis of the numbers of parasites in the gut wall of 1251 orange roughy Hoplostethus atlanticus from eight areas off southern Australia and three areas off New Zealand.

Two manuscripts were submitted for publication: Stock discrimination of orange roughy Hoplostethus atlanticus by parasite analysis by R.J.G. Lester, K.B. Sewell, A. Barnes and K. Evans, and The numbers of selected parasites in Australian and New Zealand samples of orange roughy Hoplostethus atlanticus, 1983 to 1986, by K.B. Sewell and R.J.G. Lester

The numbers of selected parasite species from 23 samples of gemfish, Rexea solandri, from seven locations off southern Australia are given. The data were examined for evidence of isolated gemfish populations. Canonical multivariate analyses of the numbers of larval nematodes (Anisakis spp. and Terranova sp.), larval cestodes (Hepatoxylon trichiurid and Nybelinia sp.), acanthocephalans (Rhadinorhynchus sp. and Corynosoma sp.), and a hemiuroid digenean from a total of763 gemfish showed that the parasite faunas of fish from eastern Australia were similar except for a sample taken off New South Wales at the end of the spawning season whose affinities are unknown.

Fish from South Australia had similar parasite faunas to those collected from eastern Australia suggesting the eastern and western Bass Strait fish belong to the same stock. Samples collected from the Great Australian Bight were distinct from the southern and eastern fish. Differences in parasite fauna were detected between samples taken within the spawning season and those taken from the same locations outside the spawning season, presumably a result of the spawning migration.
