Mature, female Macquarie perch, Macquaria australasica, were collected from the wild in the Mitta Mitta River and the Mitta Mitta River arm of Lake Dartmouth in north-eastern Victoria during the normal breeding season (Oct.-Dec.) and induced to spawn by either single or incremental, intraperitoneal injections of human chorionic gonadotrophin (HCG) at dosages of 500-1000 IU/kg HCG. Injected fish were held at 18-20°C and either spawned in brood tanks or their eggs and sperm were hand-stripped and mixed together. Courtship behaviour, following injections of HCG, is described. Only ripe fish injected with 750-1000 IU/kg HCG produced eggs that were fertilized. Females which produced eggs which were fertilised, did so within 26 h of the last incremental injections and within 38.8-42.8 h of single injections. The natural spawning mechanisms of Macquarie perch in Lake Dartmouth are described in an attempt to explain the apparently variable results of HCG-induced ovulation and spawning of this species.
