📖 Overview

Gregarious fish which swims near the surface . Inhabits moderate to fast-flowing large streams to large rivers with rock or gravel bottom. Adults aggregate in dense swarms in winter in the lower reaches of rivers or backwaters and often migrate to spawning streams in autumn and overwinter there. Juveniles spend winter in cavities along the shores. Early juveniles occur in very shallow shoreline habitats and when they grow, they leave the shores for faster-flowing waters. Feeding larvae thrive along shores. Prey on small invertebrates. Spawns in fast-flowing water on shallow gravel beds, often in small tributaries . Breeds in March and April . Pale yellow eggs are found attached to gravel and stones in shallow, flowing water .
