For fish winter starts with first frost. When water cools heat-loving carps, crucian carps and grass carp hibernate. Other underwater inhabitants remain active during these cold months. They keep on moving, feeding, hunting. And getting caught by fishermen, of course. Here on Balkhash you can catch zander, vobla, Volga pike perch and snakehead. The fish goes to quiet deep places – cavities, bays, pits. It keeps near underwater snags and islands of vegetation. Fish are cold-blooded, and in order to maintain their metabolic processes, they need to keep themselves warm. The warmest water is at the bottom.
