The parasite fauna of the viscera of 1251 orange roughy,Hoplostethus atlanticus, collected in 1983 to 1986 from eight areas off southern Australia and three areas off New Zealand, was examined for evidence of discrete host populations. Fish from each area were divided into three length groups which averaged close to 28, 37, and 42 cm. Canonical multivariate analysis of data on larval nematodes (Anisakis spp.,Terranova sp., and a spirurid) and larval cestodes (Hepatoxylon trichiuri andCallitetrarhynchus sp.) discriminated five Australian and three New Zealand stocks. These were for Australia: (1) Great Australian Bight (2) South Australia/west Victoria/west and south Tasmania, (3) Cascade Plateau/Tasman Rise, (4) north-east Tasmania, (5) New South Wales; and for New Zealand: (1) north-east New Zealand, (2) south-east New Zealand, (3) west New Zealand. No significant differences in parasite fauna were detected between samples of fish taken within the spawning season and those taken outside the spawning season in the same area. In one southern Australian stock there was a north-south cline in the numbers ofAnisakis spp. This was apparent in both small (immature) and medium-sized (mature) fish. We conclude thatHoplostethus atlanticus is a sedentary species with little movement between fishmanagement zones.
