Abstract

Tunas constitute 3.7% of the total commercial pelagic Jin fish production of the country (Av. 1992-96: 1,14.1067 t). The dominant species which support tuna fishery in the small scale sector in India are Euthynnus afflnls. Auxis thazard, A. rochel, Thunnus tonggol, Katsuwonus pelamis, Thunnus albacares and Sarda orlentalls. Of the total tuna catch (Av. 1992-96: 41,978 t). 77.6% has been landed from, the west coast, 16.8% from the east coast 5% from the Lakshadweep and 0.5% from the Andaman & Nicobar islands. The status of production of different tuna species in India and their environmental preference are summarised. Biological features such as food and feeding habits, age and growth, size at first maturity, spawning and fecundity are briefly discussed. Trends in the production of tunas along the mainland coast of India and Lakshadweep, population parameters and the results of stock assessment are presented briefly. Suggestions for future research and options for tuna fishery development in India are also discussed. The present communication is a review of the works done during the past fifty years and discusses the present status and future strategy of tuna fisheries research and development in India.
