No results found.Since the International Indian Ocean Expedition (IIOE, 1959-65), which produced abundant data on the oceanographic and biological environment, the seas off North East Somalia have been known to belong to the high productive areas of the world in terms of primary and secondary production, due to the seasonal upwelling occurring in the area. Even though direct data on fish resources were missing, it was assumed that the area could hold considerable fish resources. Based on the findings f rom IIOE, a joint programme between the Norwegian Agency for International Development (NORAD) and the Food and Agriculture Organisation of the United Nations (FAO) was set up to investigate the fish resources of the Arabian Sea. In the period from January 1975 to November 1976 the R/V “Dr. Fridtjof Nansen” carried out five coverages of the coastal waters from Pakistan to Somalia. Based on the acoustic data collected during these surveys, the fish resources of Somalia were estimated to the avera ge level of 570 thousand tonnes for the small pelagic fish and 400 thousand tonnes for demersal fish, making it one of the most productive areas in the Indian Ocean. The dominating part of the pelagic stock was located between Ras Hafun and Ras Asir, which is also the center of the upwelling system. During the years 1983-84 the vessel returned to the region under the UNDP/FAO programme GLO/82/001 “Survey and identification of World Marine Resources”, with the purpose of investigating the hi gh productive regions located during the 1975-76 surveys. In agreement with the Ministry of Fisheries in Mogadishu two coverages of the region between Ras Asir and Ras Mabber were planned for February and August 1984. The main objectives of these surveys were to update the previous findings and provide more detailed information on the state of the resources with a more intensive sampling programme than during the earlier surveys. -
Book (series)Implementation of the ecosystem approach to fisheries for the demersal fisheries of the Mediterranean coast of Egypt: baseline report 2024
Also available in:
No results found.The Egyptian capture fisheries production from the Mediterranean Sea is showing a decreasing trend that began in 2008 and continued to the present. Most of the production comes from the capture of species in the coastal zone and over the continental shelf. The Egyptian Mediterranean fishing fleet is dominated by trawlers, which represent the backbone of the fleet in terms of both economic value and employment. Trawlers work from fishing ports along the Egyptian Mediterranean coast and are not restricted by geographic boundaries; consequently, the landed fish species cannot be attributed to certain fishing grounds or definite geographic areas. Trawl fisheries are essentially multispecies, targeting shrimps, common cuttlefish and some fish species like Mullus spp., soles, brushtooth lizard fish and species of the family Sparidae. Most of the stock assessments recommend a reduction of fishing mortality by about 40 percent, with the recommendations lower for some fisheries and higher for others. Trawlers mainly sell their production through wholesalers while the small-scale and artisanal vessels channel their production primarily through the fish market. Generally, fishery management in Egypt is challenged by the complex nature of the associated social-ecological systems.
