Abstract

SummaryThe spawning status of a population of G. bispinosus from Buffalo Creek in north-eastern Victoria was monitored over two consecutive spawning seasons. Spawning occurred in December of both years and coincided with increasing water temperature. Eggs were found deposited in artificial spawning tubes placed in the creek and in the stream substrate, under small, generally flat, boulders, confirming previous authors’ assumptions. The implications of this reproductive strategy include the susceptibility of the species to increased sedimentation and cold water pollution.
