Species of O. niloticus and L. niloticus have been explained to out compete the native fish species in A total 931 fish were collected by gillnets of various stretched mesh sizes, of which 326 individuals of Oreochromis niloticus stomachs contained food. We investigated the food and feeding habits of Nile tilapia, Oreochromis niloticus, in Lake Hayq, Ethiopia from August 2008 to March 2009. Nile tilapia can filter feed by entrapping suspended particles, including phytoplankton and bacteria, on mucous in the buccal cavity, although its main source of nutrition is obtained by surface grazing on periphyton mats. They are relatively resistant to poor water quality and disease. Tilapia were exposed to approximately 21 mg/l nitrite-N after 5 and 10 weeks of feeding to determine the effect of dietary NaCl supplementation on resistance to nitrite toxicity. Biological constraints to the development of commercial tilapia farming are their inability to withstand Fry eats zoo and phytoplanktons, like Rotifera sp., Moina sp., Dapnia sp. There are three feeding charts presented below. The benthic fauna collected from the study area comprised of 7 groups of the animal kingdom represented in 10 species and other immature stages.
