Abstract
The family Alopiidae (thresher sharks) is found distributed worldwide in tropical and temperate seas. Alopiidae have one genus and three species viz., the pelagic thresher, Alopias pelagicus Nakamura, 1935, the bigeye thresher, A. superciliosus (Lowe, 1839) and the common thresher, A. vulpinus (Bonnaterre, 1788). On 20th June, 2013 a single specimen of A. pelagicus (Sex: female; total length: 270 cm; weight: 3000 g) was landed in by large meshed drift gillnet (“Paruvalai”) operated from fishing craft (“Vallam”) in Tharuvaikulam fish landing centre. The gear was operated between 100 and 150 m depth, at a distance of 60 nautical miles from the coast. The specimen was photographed and morphometric measurements were made with a measuring tape to the nearest centimeter and weight was taken to the nearest gram. The species identification was carried out based on Compagno (1984).
