Description |
Tuna samples were collected from the commercial landings at Kochi, Tuticorin, Mangalore, Visakhapatnam, Veraval and Lakshadweep at regular intervals during 2006-2010. Detailed morphometric data, viz., height of dorsal and anal fins, eye diameter, snout length, head height and height of body were collected. Otoliths were collected from eight species and analysed. Results indicated that structure and shape of the otoliths show species specific differences. Taxonomic details of tunas and tuna like species have been generated from the present as well as past studies and the species were redescribed with color photographs and keys for identification. The species included Thunnus albacares (Bonnaterre, 1788), Thunnus obesus (Lowe, 1839), Thunnus tonggol (Bleeker, 1851), Sarda orientalis (Temminck & Schlegel, 1844), Katsuwonus pelamis (Linnaeus, 1758), Euthynnus affinis (Cantor, 1849), Auxis thazard (Lacepède, 1800), Auxis rochei (Risso, 1810) and Gymnosarda unicolor (Rüppell 1836). |
