An investigation on feasibility of introduction of Tilapia to aquaculture industry of inland brackish waters at desert areas of Iran

Abstract

Use of underground inland water for fisheries aims is improved all over the world. Tilapia is the first candidate for brackish water fish culture and an economic fish based on its biological characteristics. Tilapia was entered to Iran for the first time in November 2008. Bafq area at the center of Iran was licensed by Environment Organization, because of closed underground water resources of the area. Studies showed desired growth and adaptation of Nile tilapia in brackish water earth ponds and fiber glass tanks with high survival and low FCR. Limnological factors were suitable for tilapia culture. All male samples were made using certain doses of methyl testosterone in defined period. Optimum level of protein, fat and energy were determined for the best growth and food performance of cultured tilapia. Environmental program was presented to prevent environmental problems. However, studied shoed tilapia culture had not negative effects in the area. Economical performance of tilapia culture project was desirable. Tilapia was successfully introduced to some private fish farms in June 2011. Tilapia culture may improve in center of Iran after environmental surveys.
