The continual churning of the coast by waves and the matter carried down from inland areas make beaches rich in nutrients. Add to this that the water is shallow and there is a great deal of sunlight, so there is a rich variety of life that lives and swims there, attracting shrimp and fish. Nearly 90 % of fish fry are concentrated here.
