Some Studies on Productive Performance In Nile Tilapia

Tilapia fish is warm water cichclid predominantly of Africa and middle eastern origin. tilapias can servive under a wide variety of environmental conditions, being highly eurthermal with a temperature rang between 16 and 40C Tilapia species are among the commercially important inland fishes of Egypt.
