Arrivée à la côte des alevins de poissons téléostéens dans le golfe de Tunis

Abstract

This paper concerns the study of the period appearence of some species of fish fry in the Gulf of Tunis. 120,000 fries of Grey Mullets, 1000 Seabasses, 1500 Sparidae (730 of which were gilt-heads) and 300 Eels were fished. The arrival to the coast of fry is linked to the breeding seasons. Their abundance depends on the environmental factors of the coastal waters and particularly on the temperature.
