Abstract
Nemipierus delagoae Smith releases its eggs in batches and thus spawns twice in a year. Size at first maturity has been determined as 161-170 mm. This species has extended spawning season at Vizhinjam with peak spawning season from September to January. Males dominated over females during this investigations. Annual fecundity of the individual fish ranged from 86,184 to 497,230 eggs. Fecundity of the fish increases with the increase in the length and weight of the fish while ova per gram of fish body weight has no relationship with the length of the fish.
