Temperature-induced sex reversal is not responsible for sex-ratio distortions in grayling Thymallus thymallus or brown trout Salmo trutta

On the basis of the experiments carried out over various years, it was concluded that (1) grayling Thymallus thymallus and brown trout Salmo trutta are resistant to temperature‐induced sex reversal at ecologically relevant temperatures, (2) environmental sex reversal is unlikely to cause the persist...

Description
Summary:On the basis of the experiments carried out over various years, it was concluded that (1) grayling Thymallus thymallus and brown trout Salmo trutta are resistant to temperature‐induced sex reversal at ecologically relevant temperatures, (2) environmental sex reversal is unlikely to cause the persistent sex ratio distortion observed in at least one of the study populations and (3) sex‐specific tolerance of temperature‐related stress may be the cause of distorted sex ratios in populations of T. thymallus or S. trutta.
