If recent estimates are accurate the world’s human population can be expected to double in the next thirty years. The rate of growth will likely be even greater in many African nations, yet food supplies in these countries especially of essential animal proteins, are even not; inadequate Clearly increased production of food for domestic consumption must become a high- prioritydevelopment goal.The inland fisheries of Africa will play an increasinglyimportant role in augmenting protein supplies. In 1970, production of the inland fisheries was already-about 1.4 million metric tons, and had increased some 71 per cent in the previous six years. With further development and more affective fishery management a two-fold increase 1n output over the present level can reasonably be expected.Effective management of the fisheries at optimum exploitation levels end development of under utilized fish resources will neccessite major improvement in the stastistical systems employed to produce information on the fish stocks and fisheries. More reliable and detailed information on the catch, effort and other important aspect of the fishing enterprises will be required.
