 Although remains of tiny animals have been found in their stomach, these are probably ingested by mistake when feeding on plants.Known in the local Iraqi Arabic dialect as "binni" or "bunni", this fish is valued highly by the Marsh Arabs.Their fishermen traditionally employ an unusual technique of spearfishing from a line of boats or poison-fishing with flour or dung laced with toxic "Digitalis" or "Datura"; until recently net-fishing was mostly restricted to the Berbera tribe and held in low esteem.
