In fishes, sex is determined by genetics, the environment or an interaction of both.
Temperature is among the most important environmental factors that can affect sex …

Background Fish species often exhibit significant sexual dimorphism for commercially
important traits. Accordingly, the control of phenotypic sex, and in particular the production of …

Freshwater environments cover less than one percent of the Earth's surface, but
nevertheless contain~ 10% of all described species (Dudgeon et al. 2006, Strayer and …

Salmonid fish have become important models in evolution and ecology, but possible effects
of embryo or larval sex are mostly ignored, probably because morphological gonad …

Bighead carp (Hypophthalmichthys nobilis) and silver carp (Hypophthalmichthys molitrix)
are genetically close aquaculture fish in the Cyprinidae, which have been confirmed to hold …

Fish populations can be threatened by distorted sex ratios that arise during sex
differentiation. Here we describe sex differentiation in a wild grayling (Thymallus thymallus) …

This is the third and final volume in the series on Sex Differentiation in Fish. The book
represents the first attempt to comprehensively address all issues of negative effects of …

Juvenile sex ratios are often assumed to be equal for many species with genetic sex
determination, but this has rarely been tested in fish embryos due to their small size and …

The synthetic 17α-ethinylestradiol (EE2) is a common estrogenic pollutant that has been
suspected to affect the demography of river-dwelling salmonids. One possibility is that …

Salmonids are a socioeconomically and ecologically important group of fish that are often
managed by stocking. Little is known about potential sex-specific effects of stocking, but …
