Ecological bases of the breeding of the tilapia of the nile (oreochromis nilotica) in the station of fish farming of deroua (beni mellal/morocco)

Morocco was equipped, since 2009, of a new development strategy and competitiveness of the halieutic sector. The development of this sector will make it possible to improve the means of existence by the means of the increase of the incomes, employment and the wellness. The development of the aquacultural sector will contribute in addition to the food safety and the socio-economic development of Morocco. The station of fish farming of concerning Deroua HCEFLCD is part of the one of the stations which can play a lever for the development of this sector by the whole of the scientific studies conducted to its level. The follow-up of the physico-chemical parameters during the period of reproduction of a nonnative species Morocco (Oreochromis nilotica) introduced by Egypt in 2004 shows that during the various phases of breeding as well parents whom larvas show that the physico-chemical parameters raised throughout the experience seem to suit perfectly to Oreochromis niloticus because all the registered values is meanwhile optimal of the species. These results can establish a database for the development of the aquacultural sector of this species.
