Abstract

Abstract Morphological changes in the gonads of the freshwater goby Padogobius martensi from March to October were examined. Histological analysis showed that this species has a ≪group synchronous≫ ovary and, therefore, it can spawn more than once during a breeding season. Furthermore, the species, similar to most gobies of temperate freshwaters, shows a distinct seasonality in reproductivity and has a relatively short breeding season. Associated with the testis are glandular structures similar in morphology to the ≪sperm‐duct glands≫ described in a number of gobies. They grow enormously only during spermiogenesis and exhibit apocrine secretion. A role of these structures could be secretion of sex actractant substances.
