| dc.description.abstract | The moon fish, Mene maculata is belonging to the genus Mene, family Menidae, and order Perciforms, popularly called moon fish. The present study based on the observation of a 452 total individuals ranging from 11 to 27 cm size, comprising 227 males and 225 females were collected fortnightly from Mangaluru landing centre. The length-weight relationship of M. maculata did not show any significant difference between sexes and pooled equation were drawn Log W= 0.0276 + 2.8567 Log L. The relative condition factor (Kn) values for male and female varied from 1.055-1.059 respectively. The qualitative and quantitative analysis of gut content showed that the fish mainly fed on crustaceans, fishes and occasionally on mollusks, occurrence of the mud and sand particles in the gut indicated that the fish is bottom feeder. Active feeding observed during November and December which coincides with the post- spawning season, poor feeding was noticed in the month of February and April which indicates breeding season of the fish. The overall Sex- ratio was estimated as male: female = 1:0.99. The length at 50 % maturity was found to be 19-21 cm (TL), for male and female respectively. The Gonad-Somatic Index values ranged from 0.3794 to 2.5485 in male and in case of female, it fluctuated between 0.4245 to 3.3315. Fecundity of M. maculata varied from 1,01,051 to 2,38,875 eggs with an average of 1,66,962 eggs/female depending upon the size of the fish. The ova diameter ranged from 0.04 to 0.91mm. The species is a prolonged spawner. The proximate composition revealed that the Moisture has 71.10 %, followed by protein 23.29 %, ash 3.97 %, and fat 1.91 %. | |
