Besides, there are large ports of loading platforms nearby as well as this area regarded as a fishing ground. In the current study, hydrocarbons were analyzed using the mudskipper samples that were divided into three groups according on their length, which ranged from 11-16 cm, 17.5-19.5 cm and 20-23 cm, respectively, and the fishes were divided into three groups of weight; 7.13-17.33 g, 18.6-25.33 g and 26.7-36.6 g.

The highest annual quantity landed was about 8502 tons in 2020 which formed about 27.6 % of total fish landed. In fact, this variation in fish stock from year to year could be related to overfishing, weather changes, pollution levels, water levels, market prices and environmental conditions (natural or human-made). This study also indicated that the majority of fish landed came from capture fisheries and the rest from fish farming. Eleven fish species were observed and Cyprinus carpio was dominant with 37 % of the total weight landed followed by Planiliza abu which comprised about 25% of the total. Six native species, two alien species and two migratory species were also found throughout this investigation which composed about 41.3 %, 56.5 % and 2.2 % of the total, respectively.","PeriodicalId":259361,"journal":{"name":"Mesopotamian Journal of Marine Sciences","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122696499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The uptake of Cd by M. edulis was at its maximum at low salinity and high temperature while at high salinity, temperature did not significantly affect the rate of uptake.
