Synopsis (short abstract) Management of fisheries resources should be an integral factor in their development. The application of sound management principles cannot await the period of heavy exploitation lest the opportunity to derive a high sustained yield by then have past. Biological factors important to management decisions can be described by the relation of catch to: the total amount of fishing (the fishing mortality coefficient, or the proportion of the stock which is caught per unit of time), and the sizes of fis h caught. Effective management decisions are the result of the objectives of management action; what is intended? To maximize production from a particular fishery, or from the fishing industry in general? To maximize net economic returns? To improve the situation of the fishermen? A wide range of methods of management is available, including limits on seasons, fishing grounds, fish sizes, gear, catches and amount of fishing. The cost of enforcing regulations must be subtracted from the gross ben efits accruing in order to find the true net benefits

    The paper describes the benefits that can be achieved from proper management of shrimp resources and the problems involved in achieving this. In the absence of management, fishing will expand to the level where it is no longer profitable; at this level the catch may be less than with reduced fishing, and the costs very much greater. Implementation of management is easier if early consideration is given to the problems involved. Early action is also necessary to collect the basic data required la ter to assess the stock and determine precise management measures. The possible management measures include protection of the small shrimp, e.g., through the prohibition of fishing at certain places or seasons, and the direct control of the amount of fishing or the capacity of the fleet, e.g., by license limitations. The choice of the latter control, including the conditions under which licenses may be held, will depend on the use that is to be made of the considerable surplus that can occur of the value of the catch over the minimum costs of harvest. Management of the shrimp fishery should look into the need to make the best use of the fish that are caught incidentally when shrimp fishing. The quantities involved can be considerable. Proposals are made for this and for progressive step-wise approach to the management of a developing shrimp fishery.

    The Government of Somalia has acquired a fleet of commercial fishing vessels and has requested advice from the Indian Ocean Programme on their management. The present report reviews the vessels operational possibilities as well as the actions necessary to realize them. The report recommends that management be contracted to a suitably qualified fishing company and that a state-owned corporation be established to own the vessels and eventually to manage theme The report contains financial and staf fing tables and an outline of points for a corporate statute and a management contract.
