| Abstract | ||||
| Bardawil lagoon is one of the northern lakes in Egypt and has an exceptional significance where it is the least polluted wetland in Egypt and represents one of the least polluted lagoons in the whole Mediterranean region. The catch in Bardawil lagoon is composed of a high-valued fish species like grey mullet, soles, seabass, seabream, eel, meager and grouper. The lagoon covered a total surface area of about 650 Km2 and employing more than 4,000 fishermen. In 2022, 4283 tons were landed from the lagoon, achieving more than 350 million Egyptian pounds. A number of fishing methods are used in the lagoon including trammel nets (Dabba), veranda nets (El-Bouss), lines (sinnar), dubdeiba, crab nets, and dahbana nets. The fishery statistics (catch and effort data) are necessary in the stock assessment studies, as they constitute the basic input for the surplus production models SPMs which established to determine the equilibrium or sustainable yield that may be harvested from a fishery for a given level of effort. The present work was undertaken to evaluate the fishery status of Bardawil lagoon fishery as well as to estimate the maximum sustainable yield for four commercial stocks; soles, grey mullet, crabs and shrimp. The study will help fishery managers develop and implement the fisheries regulations in the lagoon. | ||||
