Abstract
Nowadays, fish production aims to achieve a continuous and immediate generation of top-quality animal protein from the finest sources. Moreover, the aquaculture industry holds a vital position in addressing the rising global appetite for fish and seafood products. Additionally, it has played a substantial role in providing affordable animal protein in Egypt in recent years. Therefore, a rapid development has occurred in the industrial aquaculture sector in Egypt to compensate the decrease in the red meat production. According to previous studies, Egypt occupied the 1st rank among African countries and the 9th position globally in the field of fish farming production. This achievement aimed to link up the disparity between fish production and consumption in Egypt. Carp, due to its economic importance in this industry, has expanded worldwide with more evident ecological influences. The Carp fish belongs to the Cyprinidae family, which encompasses seven subfamilies, approximately 220 genera, and has been associated with around 20,000 documented species. Given the importance of carp with different species, this work reviews the management, behavior and different rearing systems of some popular carp species in Egypt. Data search was done on PubMed, SCOPUS, Web of Science, Google Scholar for the keywords including fish farming, carp fish, management, behavior, rearing systems, Egypt, Africa, and Worldwide. In Egypt, the output of carp is ranked second only to tilapia in aquaculture. A polyculture system is more often used in carp rearing, particularly when raising tilapia, in order to maximize growth rates, minimize feed conversion ratios, and reduce the amount of fat in the corpses. Furthermore, agro-ecologically valuable agriculture has been linked to integrated carp monoculture. Crop rising was the key to the successful development of pond aquaculture.
