Abstract

The Gulf of Suez is relatively shallow and extends about 314 km
south-southeast from Port Suez in the North (Lat. 29° 56` N) to
Shadwan Island in the South (Lat. 27° 36` N). Its width varies between 20
and 40 km and its depth throughout its axis is fairly constant
with a mean depth of 45 m.
The aim of the present work is to determine the structure of juvenile
fish community inhabiting coastal shallow water of North Gulf of Suez to
describe species composition, size structure of juvenile fishes and time of
recruitment in the target areas to assess the important of ecological
habitats for economically important fish species and study the food and
feeding habits of dominant juvenile fish species.
The by-catch of about 3-5 Kg per haul was collected seasonally by
experimental beach seine operating in Eion Moussa, Ras Sader, and Ain
Sokhna coasts, North Suez Gulf, Egypt during the period from autumn
2017 to summer 2018 was analyzed.
The by-catch amount 3-5 Kg per haul in Eion Moussa composed of fin
fish species (84.3%) and shrimp (15.7%). About 17 fin fish species
belonged to 14 families composed of two categories 13 juvenile of the
commercially important species (30.6 %) and 4 low valued species
(69.4%). Leiognathus berbis, Leiognathus elongates, Encrasicholina
punctifer and Istigobius ornatus dominated the assemblage of 17 species
and contributed 69.37% of all sampled fishes.
