Chub

The chub (Leuciscus cephalus) is a gregarious fish that lives in oxygen-rich flowing water. It lives quite close to the surface during the summer and drops to the bottom at the first frosts, where it stays until the spring. The breeding season of the chub is between April and June. Its young live in shoals, becoming solitary when they reach maturity. This fish has rayed fins. It has a varied diet, feeding on plants (phytophage), but also other fish.
