ABSTRACTamily Carangidae includes the most abundant species in purse-seine fishery in the Gulf of Suez, where it constitutes about 39% and 6% of the total production of purse-seine and trawl fisheries respectively. Fishery statistics (catch, effort and catch per unit of fishing effort) of the carangid fish exploited by purse-seine and trawl fisheries during the fishing seasons from 1979/80 to 2003/04 were analysed to assess the effect of the two types of fishing gears on the annual carangid production. The maximum sustainable yield (MSY) and the corresponding level of fishing effort (f Kjlcv ) were estimated as limited reference point using the IVlo Y Schaefer surplus production model. In addition, 2/3 f MSY and the yield corresponding to this effort were calculated as precautionary target reference points. The obtained results indicated that carangids were overexploited in the Gulf of Suez. For achieving the precautionary target reference points, it was recommended to reduce the fishing by about 59.6% and 47.2% for trawl and purse-seine fisheries respectively. In general, the standardized fishing effort of both gears should be reduced by 46.9%. The results showed that reduction of fishing effort to such levels will increase the marginal revenue in term of CPUE by about 33%. Regulating mesh size and defining closed area are recommended as well as studying the gear selectivity and developing a geographical information system for fishing ground in the Gulf of Suez.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
