Abstract
During 1995, a study was undertaken to monitor and evaluate the recovery of Swan River black bream stock which had been supplemented with fish produced from a captive-breeding program. Fish were individually tagged and subsequently released into the Swan River. The objectives of the study were (a) to determine both the survival and the growth rate to a size at which hatchery-reared fish could enter the recreational fishery and (b) whether they could then be caught by the recreational fishers. Of the 767 fish released into the upper Swan River on 28 March 1995, 97 fish (12.6%) were recaptured to the end of October 1997.
The results from this initial study show that captive-bred black bream released into the Swan estuary can survive and grow in the wild and may also be more catchable than wild fish. The results also show that captive-bred fish introduced into the wild can ultimately contribute to the recreational black bream fishery.
