title: Aspects of the Reproductive Biology of Black-Striped Pipefish &lt;i&gt;Syngnathus abaster&lt;/i&gt; Risso, 1827 (Actinopterygii: Syngnathidae) in the Zaporizke Reservoir, Ukraine
abstract: Black-striped pipefish Syngnathus abaster Risso, 1827 (Actinopterygii: Syngnathidae) has successfully spread in freshwater ecosystems of Ponto-Caspian basin. Monitoring studies show a steady increase in the number and biomass of pipefish in waters of Dnipro region. It is highly adaptable and breeds in a fresh water. This fact indicates the physiological plasticity of the reproductive system and ability to adapt to new environmental conditions. In the Zaporizke Reservoir pipefish spawns at a temp
