Abstract
Fishing and hunting are among the oldest professions
of
mankind, eversince man began his search for food. Men have always taken the resources of the waters for granted, but as populations grew and nations industrialized, they have expanded and industrialized their fisheries to keep pace with the increased demand. For fish is one of the staple foods, one of the richest of all sources of animal protein, and in a world faced with a population explosion it may be essential to mankind’s continued survival. The amount of fish taken from the world’s waters has been rising year by year and today it totals about 83 million metric tons; some 15 percent of this total are provided from inland fisheries (FAO, 1986). In Egypt, inland fisheries including the northern Delta lakes are far more important than the marine ones, especially after the construction of the Aswan High Dam and the cessation of the Nile flood that used to enrich our coasts with highly nutrient-rich waters; inland fisheries provide about 81% of the total fish yield.
The world population as estimated in 1984 was 4,764x10”, hence the annual share per capita of fish would be 17.37 kg. In Egypt, however, the annual share per capita of fish do not exceed 3.00 kg.
