Abstract
This study aims to assess the economic & environmental feasibility of fish cages in Damietta Branch, Egypt. To achieve this goal, economic &Environmental data on 321 fish cages were collected in 2014.The data were analyzed using quantitative statistical analysis.The result indicated that cagefarmers in Damietta Branchadoptaquaculture of eitherNile tilapia orsilvercarp, andaquaculture ofbothspeciestogether. Theaveragereturnon sales of thesefishspecies in thesetwosystemswere17, 67 & 18% respectively.Theresultsalsorevealedthatfeedconversion ratio (FCR) washighforcaged tilapia, leading tosome negative impactsontheaquatic environment. This has, in turn, affectedotheractivities, andtherefore extended thenegativeimpact of suchactivities on cage culture activity in Damiettabranch.
