Spontaneous locomotory activity of galaxias vulgaris stokell(pisces: Salmoniformes)

Abstract

Feeding of captive Galaxias vulgaris was found to be dependent on open‐water activity. It did not occur when fish remained beneath boulders. Pat'erns of spontaneous locornotory activity of individual fish were recorded to determine potential feeding times. The apparatus used to measure spontaneous locomotory activity is described. Fish were found to be active mainly at night for most of the year, but became predominantly diurnal during the spawning period. © 1975 Taylor & Francis Group, LLC.
