Abstract
The accumulation of parasites in a fish host is modelled as a function of the total amount of prey consumed. The accumulated parasite load i s then expressed as a function of fish length so that the asymptotic g rowth, L infinity of any population of commonly infected fish can be e stimated. Estimates of L infinity are obtained for orange roughy (Hopl ostethus atlanticus), albacore tuna (Thunnus alalunga) and the New Zea land southern arrow squid (Nototodarus sloanii).
