Tuna long line fishery was introduced in the early 80s and was established after the initial break through around 1986-87. CIFNET undertook a new exploratory tuna long lining programme jointly with Fishery Survey of India under the technical guidance of Capt. Haruta, a long line Expert sponsored by the Japan International Co-operative Agency (JICA) under Japanese Aid programme. After systematic training, the vessel was handled entirely by the Indian crew. The experience gained all these years and the training received from the expert gave confidence to the crew. Scouting for Tuna and catching in the commercial style were set as the target. As a result, valuable information on resources of Tuna and long line Tuna fishing technology for Indian seas were developed. Prashikshani operated from 6 degree South of equator to 17 degree North of equator in the Indian Seas getting various hooking rates. The most abundant fishing grounds where Prashikshani exploited tuna resources are given in the figure below:
Within this small span of time, the result proved that Indian waters has potential Tuna fishery which is evident from the above chart which gives the hooking rate ranging between 2.1 % to 22.7%, a very encouraging rate. The training cum survey conducted by the institutional training vessel M.V.Prashikshani during 80s helped in locating potential tuna grounds in the Indian EEZ. The institute has also contributed by training the personnel required for this sophisticated fishing method.
