Rainbow trout larvae were kept in acid water from 16 to 55 days after hatching. Initially, the acid environment stimulated a significant increase of gametes in the gonads of females at all developmental stages, but after longer exposure the stimulation was replaced by inhibition of gonadal development in the treated fish. In some fish, gamete reserves increased, while in others there was increased growth and maturation of late‐generation oocytes.
