Abstract

Environmental sex determination by temperature could be revealed significantly in 33 Apistogramma‐species and in Poecilia melanogaster . In some, but not all, Apistogramma‐species pH also influences the sex ratio, whereas neither temperature nor pH affect the sex ratio of Pseudocrenilabrus multicolor victoriae . The sex in offspring of A. trifasciata is determined within a sensitive period of about 30 to at least 40 days after spawning.
