Thirty nine immigrant fish species from the Red sea were observed in seven regions of Egyptian Mediterranean waters during 2013- 2021. These were divided according to their importance in the fish markets into economic species (18) and non-economic species (21). Port- Said region (North opening of Suez Canal) constituted high percentage of occurrence (49.1% of all species) followed by Alexandria (41.9%), Abu-Qir (5.2%) and Marsa Matruh (3.7%). Thirteen new species were recorded in the present review whereas fifteen fish species in the checklist given by Halim and Rizkalla (2011) were not encountered in the study area during the study period. Alepes djedaba and Siganus rivulatus were the most important economic species established in Port Said region, whereas Nemipterus randalli and Sargocentrum rubrum were the more dominant in Alexandria region, Also Nemipterus randalli was well established in Abu-Qir area while Upeneus pori was abundant in Marsa Matruh region.
Red Sea fish market assessments indicate high species diversity and potential overexploitation
