    Catches, fishing efforts, catches for fishing effort, and fishing locations for the Gulf of Suez and Egyptian Red Sea coast trawl fishery during 1979 to 1982 1984
    Also available in:
    No results found.

    This report presents a collation of data describing the monthly catch weights by important species groups, the associated fishing efforts and catch weight per unit effort, and the fishing locations, for a period of 3 years from 1979 to 1982. Data collection involved catch enumeration at the landing sites by employees of the Department of Agriculture, and the interviewing of skippers for details of fishing efforts and fishing locations by project personnel and counterparts. The mean annual catch of 4973 tons from the Gulf of Suez is tentatively suggested as reflecting full exploitation. The potential annual catch estimated for the less exploited grounds adjacent to the Egyptian border with Sudan is 1111 tons; which is some 378 tons more than the 1982/1983 catch.

    An incomes and costs study of the Egyptian trawl fishery operated in the Gulf of Suez and off the Southern Red Sea coast during 1980-81 1983
    Also available in:

    The incomes and costs of the Egyptian trawl fleet operated in the Gulf of Suez and off the southern Red Sea coast during 1980-81 are described in this report. A principal source of data arose from interviews with the boat owners and/or skippers of eighteen boats. Some aspects of the management were discussed. The importance of shrimps and lizard fish, which represented respectively 33% and 44% of the gross value of the catch, was noted.

    An incomes and costs study of the Egyptian purse seine fishery operated in the Gulf of Suez and off the southern Red Sea coast during 1980-81 1982

    This report describes the incomes and costs of the Egyptian purse seine fleet operated in the Gulf of Suez and off the southern Red Sea coast during 1980-81. The principal data sources were the official statistics of daily landings, interviews with marketing agents in respect to obtaining prices, and interviews with boat owners and/or skippers for obtaining the costs. Some aspects of the current management regime were discussed. The practice of requiring some 10% of the landings at the principal landing site to be marketed at Suez, rather than in Cairo where higher prices are obtained, was shown to represent a subsidy to the population in Suez of about 3% of the gross income. A comparison of the economic performances of the boats operated in the Gulf which were managed under a regime of license limitation with the performance of the boats operated in the unlimited 'outside' the Gulf part of the fishery, indicated that the latter boats were performing marginally better. Another aspect o f management discussed was the labour cost savings that could result from the introduction of power block for hauling the nets.
