Pike-perch are typical warm and calm water fish. They do not live in rheophile waters. They are found in the water
courses of the bream zone and in lakes with warm water in summer. They prefer sandy or sandy-muddy bottoms rather than muddy-clay bottoms.
Pike-perch spawn in the spring soon after perch when the temperature of the water reaches 12 to 16 0C. This generally happens at the end of April or
the beginning of May. Pike-perch spawn in couples. They choose water at least 1 m in depth with pretty hard, sandy or gravel beds. The eggs are laid, preferably
on aquatic roots, at a ratio of 200,000 per kg of female. They are 1.0 - 1.5 mm in diameter and stick to the substratum. At the temperature of 11 to 14
0C, the eggs hatch after 8 to 10 days.
