The upstream movements of fish in the Plenty River, Tasmania

A trap was installed in the Plenty River, southern Tasmania, in order to investigate upstream fish movements. The trap was monitored from May 1978 to September 1979. The catch included the lampreys mordax and Geotria australis, the galaxiids Galaxias maculatus, G. truttaceus and G. brevipinnis, the sandy Pseudaphritis urvillii, the short-finned eel Anguilla australis, and a small number of blackfish Gadopsis marmoratus. The significance and timing of the movements of each species are discussed and related to existing knowledge
