Sivakami, S (1995) Fishery and biology of the carangid fish Megalaspis cordyla (Linnaeus) off Cochin. Journal of the Marine Biological Association of India, 37 (1&2). pp. 237-248.
The paper embodies the fishery and biology of the Horse mackerel Megalaspis cordyla off Cochin. West coast of India contributes to the bulk of the catches in All India landings. The species is caught mainly in trawls, drift gill neb and purse seine from the area and landed at Cochin Fisheries Harbour contributing upto 13.76% of the carangid landings of the centre. The catch of M. cordyla at Cochin forms upto 11.26% that of Kerala. Seasonally, at Cochin Fisheries Harbour, M. cordyla is caught during pre-monsoon (January - May), and post-monsoon period (Octo,ber - November) in trawls, during monsoon and pt-monsoon (May-December) in drift gill nets and only during September-October months in purse seine. M. cordyla exhibits a food preference for fishes especially Stolephorus spp. The species has a prolonged breeding yason extending from April to February with a peak during May to August, as has also been evidenced by Gonadcsomatic index. Size at maturity of M. cordyla in both the sexes is 251- 270 mm. Chi-square test of sex ratio showed an overall dominance of females in the population. Fecundity of the species ranged between 91854 to 324292. There was no significant difference in the length weight regression coefficient in the two sizes. Therefore a pooled fit for both the sexes together was drawn as Log W = -4.311030 + 2.687944 Log L.
