    Stock assessment for the horse mackerel, Trachurus indicus, caught by purse seine and trawl in the Gulf of Suez 1984
    Also available in:
    No results found.

    This report describes an assessment of the horse mackerel stock based on catch sampling undertaken during the three seasons from 1979/80 (incl.). Spawning is shown to occur from January through May in each year; and first sexual maturity to occur during the year prior to age 3 years. The recruitment of young fish is concluded as taking place between seasons. Yield per recruit analyses indicate that increases above the contemporary levels of fishing effort would be associated with negligible addi tional catch, and possibly reduced catches; while substantial reductions in fishing effort would be associated with only small consequential decreases in catch. Reduction in the duration of the fishing season, while maintaining fishing efforts constant, are shown likely to be associated with little change in catch.

    Catches, fishing efforts, catches per fishing effort, and fishing locations for the Gulf of Suez and Egyptian Red Sea coast purse seine 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 weights per unit effort, and the fishing locations, for a period of three 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.

    Stock assessment for the goldstripe sardinella (Sardinella gibbosa) caught by purse seine from the Gulf of Suez and more southern Red Sea waters 1984
    Also available in:
    No results found.

    The UNDP/FAO Project for the Development of Fisheries in the Red Sea and Gulf of Aden RAB/83/028 (previously RAB/77/008 and RAB/81/002) commenced a joint biological study of the Gulf of Suez and Egyptian Red Sea fisheries during late 1979. Emphasis was directed towards the collection and analysis of data relevent to assessing the state of the fish stocks, and providing an improved basis for the management of the fisheries. This report contains the fifth of a series of stock assessments based on these data. It deals with the Goldstripe sardinella which is caught by purse seine principally from the Gulf of Suez, but also from more southern waters off the Egyptian Red Sea coast. During the study period the Goldstripe sardinella contributed up to 15% of the purse seine catches from the Gulf of Suez; and up to 20% of the catches from the more southern ground within and adjacent to Foul Bay.
