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
