Abstract: Mechanisms of sex determination in fish are complex and changeable procedures,and usually depend on interactions between genetic and environmental factors.Great progress in identification and characterization of fish sex determination and differentiation related genes has been made with the development of molecular biotechnology. It has been shown that sex determination and differentiation are influenced by environmental factors including temperature,photoperiod,pH,hypoxia,and water pressure in most fishes.Types of sex determination and differentiation,genetic sex-determination(GSD)and temperature-dependent sex determination(TSD),are proposed.Sex determination and differentiation is largely affected by temperature.The current advances on molecular players are reviewed,including Sox9,Dmrt 1,Amh,Foxl2,and aromatase genes,which are involved in sex determination and differentiation in fish temperature-dependent sex determination and differentiation,including temperature-dependent sex determination and genetic sex-determination plus temperature effects are emphasized.The influence of temperature on sex ratio of fish is discussed to provide valuable insights for elucidation of mechanisms of sex determination and differentiation in fish and for design of better fish breeding and reproduction programs in farmed fish.
