Some observations on the fishery of Chorinemus lysan Forskal of the Rameshwaram Island with notes on its biology

Abstract

Several species of carangids are known to occur in the Palk Bay and Gulf of Mannar in the vicinity of Mandapam of which Selaroides leptolepis, Selar kalla, Caranx sexfasciatus, C. carangus C. ignobilis, Carangoides armatus, Atropus atropus, Megalaspis cordyla and Chorinemus lysan are the most common species and important from the fishery point of view. Krishnamurthi (1957) estimated that the first three species mentioned above, usually caught in the shore seines, contributed to 2.72% and i.66% of the total catch of fish on the Rameswaram Island in the years 1952-53 and 1953-54 respectively. The occurrence of other species of carangids has been stated to be sporadic and hence considered commercially unimportant by him.
