Abstract

The Great Bitter Lake, Suez Canal trash collection via experimental beach seine from summer 2023 to spring 2024 was examined. For the catch of each journey, a total of 3– 5kg of fin fish (81.7%) and shrimp (18.3%) were caught in each haul. There were 22 finfish species in 12 families, which were divided into two groups: 8 small fishes (5494 individuals) (58.92%) and 14 juveniles of commercially important species (3829 individuals) (41.07%). Approximately 53.4% of the commercially significant species' juveniles were recruited in the spring of 2024, 21.7% in the winter, 15.1% in the summer, and 9.8% in the fall of 2023. In summer 2023, an estimated 51.8% of small fish species arrived, followed by autumn (30.5%), spring (2024) (12.7%), and winter (5.1%). Rhabdosargus haffara, Diplodus noct, Rhabdosargus sarba, Sparus aurata, Alepes djedaba, and Liza caranita and Liza ramada recruit young in spring. The juveniles of Siganus rivulatus and Argyrosomus regius recruit in summer and fall, while Mugil cephalus, Liza aurata, Terapon puta, and Pomadosys stridens recruit inwinter. In fall and winter, recruitment is that of Saurida undosquamis.
