Abstract
Three experimental fishing operations were conducted in the Gulf of Suez during October 2018, January 2019, and September 2019 to analyze the species composition of fishes caught by trammel nets and gill nets. Trammel nets and gill nets are important artisanal fishing gears in the Gulf of Suez. The main catch of the trammel net contained 16 species belonging to 11families, on the other hand, the catch of gill net was dominated by 4 species belonging to 4 families. Concerning the trammel net, three species constituted about 89.19 % of the total catch (Gerres oyena 33.87%, Siganus rivulatus 25.32%, and Rhabdosargus haffara 20.0%). While the catch of gill net composed of 4 species Siganus rivulatus (51.69%), Liza carinata (32.17%), Gerres oyena (14.14%), and Diplodus noct (1.99%). The results of the length-weight relationships for 9 species revealed that 6 species have isometric growth, two species namely Pomadasys stridens and Liza carinata showed negative allometric growth whereas one species, Siganus rivulatus has positive allometric growth. The mean condition factor, K for 9 fish species in the Gulf of Suez ranged from 1.0 for Liza carinata to 1.6 for Stephanolips diaspros. The provided data can be used as a basis for proper management of the fisheries of these species in the Gulf of Suez.
