The tubercles function on Mahseer

The Mahseer is oviparous and the sexes are separate. During spawning season males develop pigmented granules (tubercles) on side of snout and below the eye and are easily distinguished from the female ones. The tubercles function is in maintenance of body contact during spawning, in defense of nests and territories, and possibly in the stimulation of females during breeding.
