Short description
Chiavi di identificazione | Morfologia | Morfometria
Inhabits pools, backwaters and main channels of small to large rivers. Also occurs in lakes and impoundments. Feeds on shellfish and algae, by grinding with the bony plates in its throat (Ref. 9988). Appears to be a good candidate for aquaculture. Marketed fresh and eaten pan-fried, broiled and baked (Ref. 9988).
