Reproductive biology and quantity evaluation of the Black-striped pipefish Syngnathus abaster (Eichwald, 1831) in the Zaporozhian Reservoir

The article presents the results of biology and ecology studies about the black-striped pipefish Syngnathus abaster (Eichwald, 1831) in the Zaporozhian Reservoir. Quantity and biomass of fish fingerlings and yearlings in different parts of the reservoir was determined. For the first time the reproductive indicators of pipefish in Zaporozhian Reservoir were investigated: the timing of spawning, fish fertility analysis, information on the number of embryos in the brood chamber of males were shown.
