Аннотация: Among teleost percoid fishes (Percomorpha), the subordes Scorpaenoidei (Scorpaeniformes) and Zoarcoidei (Perciformes) are of particular interest due to the presence of intermediate stages between oviparity and viviparity in several species. We analyze the features of reproductive biology in the fishes of the suborder Scorpaenoidei, including morphology of the urogenital system, gametogenesis, gamete ultrastructure, and embryonic development. The new materials are represented for three tropical coral reef fish species with external insemination from the family Scorpaenidae ( Scorpaenopsis possi , Sebastapistes cyanostigma , and Dendrochirus zebra). In particular, a hypertrophied urinary bladder used for storage of mature sperm for insemination of pelagic egg clutch is described in the males. Evolutionary transition to viviparity within the family Sebastidae is discussed. Alternative reproductive strategies are registered in viviparous fishes from the suborders Scorpaenoidei and Zoarcoidei. They are connected with the production of a large number of morphologically weakly developed larvae and a small number of individuals at the juvenile state, respectively.
