Abstract

Auxis thazard, commonly known as frigate tuna represents an important group of coastal tuna species occurring in the Indian waters. The species is landed all along the Indian coastline and the major landing is along the south-west coast with Kerala contributing the most. The species is exploited by a variety of gears viz., drift gill nets, shore seines, ring seines and hooks and lines. Though there is recent information on the fishery and the exploitation status of Auxis thazard from Tuticorin (Kasim, 2002; Abdussamad et al., 2005) and Veraval (Ghosh et al., 2010), studies on the catch, population characteristics and stock estimates covering the entire coasts of India are lacking after the work of Silas et al. (1985) and James et al. (1993). These studies date back to two decades, after which there has been a change in the fishing pattern of coastal tunas throughout the country. Therefore, the present study was undertaken to provide an insight into the fishery, population dynamics and stock structure of A. thazard exploited from Indian waters
