Abstract

The Dusky-finned Bullseye, Priacanthus hamrur (Forsskal) exhibited five maturity stages, with two peak spawning seasons, March-August and November-December. Southwest and north east monsoons play an important role in the reproduction in this fish. The minimum size at maturity was found to be 198 mm. In the commercial catches, the sex ratio showed no significant deviation from the general pattern. ie., 1:l ratio. The maximum fecundity noted was 1,52,112 eggs. A linear relationship exists between fecundity and different variables such as total length, body weight and ovary weight.
