During these four decades a wealth of information has been collected and disseminated to the user sector. The attempts made with the specific purpose of understanding the dynamics of the marine fishery resources through biological and environmental studies coupled with the development of suitable mathematical models have been highlighted in the papers presented at the symposium. Further, the studies have led to an understanding of the distribution and abundance of commercially important marine fishery resources along with their spatial and temporal fluctuations and to monitor the impact of effort on the stocks exploited. This has provided the- basis for rational and judicious exploitation of these renewable resources. These resources, being dynamic, demand constant monitoring' which is systematically and scientifically done by various research institutes, state and central organizations and universities. In this context the key role played by CMFRI as the nodal organization in India for marine fisheries research needs no emphasis and it was fitting that the Symposium was held at Mandapam Camp, the headquarters of the Institute till 1970. This Symposium has provided an effective platform for interaction among various research workers, administrators and entrepreneurs, discussing the important aspects of R & D presented in the form of papers. Also, on this occasion, the Institute, for the first time, released State-wise appraisal reports based on analysis of data collected during the period 1975-84, which is a landmark in the history of marine fisheries research. This publication is the first part of papers presented at the Symposium, and the rest of the papers will be published in two other parts which are to follow. It may not be out of place to mention the commendable work done in editing thess papers by the Editorial Committee, first headed by Dr K. Alagarswami, the then Jt. Director, and then by Dr K. Alagaraja, Sr. Scientist. The Committee, in addition, had Sri M. S. Muthu, Dr. N. G. Menon and Dr. K. J. Mathew, Sr. Scientists. But for the efforts of ail of them and the unstinted help received from the experts for screening, refereeing and editing the papers, this publication would not have been possible. It is sincerely hoped that this publication would be made use of by scientists, administrators, entrepreneurs and industry to promote the marine fishery research and development in this country and would remain a valuable addition to the Institute's publications in this area.

K. Srivastava Professor and Chairman, Research, Indian Institute of Management Ahmedabad 380 015 ABSTRACT Marine fisheries will have to play a crucial role in augmenting supplies both In the domestic as wall as export markets. Thrust of the development will be on deepsea and brackishwater resources. Ths exploitation of these resources, particularly deepsea, will require a rapid transition from charter of vessels to joint ventures aid owned fleat with modern and sophisticated technology. Creation of sizeable owned fleet wou'd require massive credit and fiscal aupport. I his thrust for exploitation of deepsea resources can be sustained with concerted attempts to formulate and implement strategies for product development and marketing In both domestic as well as export markets. This will also require the attention to develop the necessary infrastructure to hendle such vessels, onshore processing facilities, batter management of fishing harbours, cold chiin grid in the domestic markets, development of trensit and terminal markets at wholesale and retail levels. Boatbuilding yards will have to take up new challenges. This also throws up challenges for net-marketing industry in this country. All these developments would also require massive efforts for training and development of manpower. This paper deals with all these areas in a systems framework and suggests appropriate policy suppoit measures for strengthening various elements of the system. The country has made remarkable progress tern Europe and elsewhere) have accounted for in the sea food exports particularly in the recent not more than 15% of the total value of the sea years when the export has crossed Rs.
