The spawning periodicity of Photopectoralis bindus (Valenciennes, 1835) was studied off Mangaluru coast from September 2015 to April 2016 using 490 specimens with total length 6.8-12.3 cm (9.6±0.9 cm) and body weight 4.6 -30.28 g (14.20±3.59 g). Results indicated that the average sizes at maturity were 9.3 cm (males) and 9.5 cm (females). The male-female ratio was 1:0.72. Absolute fecundity estimated was 9349±853 eggs that increased with fish size (R2 = 0.92). Higher gonado-somatic index (GSI) was observed in post-monsoon season with peak value in December (female: 3.39±1.00%; male: 2.84±0.796%) indicating seasonal spawning of the fish. |
