Abstract

During January - February 2013, heavy landings of the shortfin mako shark Isurus oxyrinchus (Family: Lamnidae) by multiday gillnet-hooks and line units were observed at Cochin Fisheries harbour (CFH) (Fig. 1a & b). I. oxyrinchus is generally seen in the landings by gillnet-hooks and line units (operated off the west coast of India extending from Kerala to Gujarat coasts) at CFH, but in small numbers of larger specimens. The start of 2013 fishing season witnessed heavy landings of this species, of a wide size range (100 – 220 cm total length; 7 – 75 kg weight), dominating the shark landings at CFH second to Carcharhinus falciformis on certain days. The length-frequency distribution as well as detailed biological aspects of this species is currently being studied as part of the Institute research project on “Assessment of elasmobranch resources of Indian Seas”
