Abstract

The negative impact of the Purse – seine, Trammel net and Trowel net on the Mediterranean catch on the Sinai coast was studied by taking monthly samples of 20 kg of each type of catch within each fishing methods during 2016. Fish were distributed to small fish and mature fish according to length and weight at maturity according to previous studies of these species in the same area or adjacent areas. The results showed that the percentage of small fish 55% of the production of the Purse – seine and 27.5% of the production of the Trammel net and 42.2% of the Trowel net. The negative impact on the biomass was 923.2, 1061.7 and 160.8 tons for each of the Purse – seine , Trammel net and Trowel net respectively, with a total of 2145.4 tons in one fishing season 2016 and 212 million pounds in the Mediterranean of coast Sinai.
