Abstract
Environmental sex determination by temperature could be revealed signi ficantly in 33 Apistogramma-species and in Poecilia melanogaster. In s ome, but not all, Apistogramma-species pH also influences the sex rati o, whereas neither temperature nor pH affect the sex ratio of Pseudocr enilabrus multicolor victoriae. The sex in offspring of A. trifasciata is determined within a sensitive period of about 30 to at least 30 da ys after spawning. (C) 1996 The Fisheries Society of the British Isles
