The head of the National Research Centre of Saline-water Aquatics Bafgh (Yazd) in the Rouyesh live TV program on the IRIB Amoozesh noted that tilapia entered the country for the first time since 2008 and said: This fish is low in fat and relatively high in protein. Its omega-3 content is higher than that of turkey, chicken and beef. Therefore, its consumption will be beneficial for all ages. He stated that the production of tilapia in the world is about 7 million tons and added: More than 50 countries around the world are involved in tilapia farming. In addition, during the past years, the growth and development of this industry in the world is estimated at 15 %, which is a significant number compared to that of the other fish species. According to Dr. Alizadeh, at present, although aquaculture production in the country such as rainbow trout, carp, shrimp, etc. reaches 500,000 tons, but tilapia has no share in aquaculture production in the country. However, it seems that our understanding of this fish is now better and our researchers have made valuable scientific findings in this regard that could be a beacon for the future of the industry. Especially considering that the climatic conditions of the country and the availability of brackish water are blessings that should be used. The official of the National Research Centre of Saline-water Aquatics Bafgh (Yazd) said: The sustainability of the aquaculture industry in any country depends on the diversity of the species. Now, due to the limitations of fresh water resources in the country, tilapia can be one of the desired species for diversity in the aquaculture industry. Since this fish can tolerate harsh conditions well and grow in high density. In addition, access to juvenile fish is possible in all seasons and there are no supply restrictions for tilapia fish feed. He emphasized: Due to the type of farming it has in enclosed systems, this fish is free of all kinds of toxins, heavy metals and even antibiotics and is considered organic. Of course, because the fatty tissue in this fish is very low, the absorption of toxins is very rare and its nutritional value is very high. According to Dr. Alizadeh, although in the past years, due to lack of knowledge about tilapia, its farming was banned, but with the increase of scientific and practical information about this fish with the efforts of the fisheries researchers, it can be farmed in enclosed systems, greenhouses and even without wastewater production. It is possible to produce monosex tilapia for farming, all of which remove environmental barriers. At the end, he said: Currently, 5 provinces of the country have received tilapia farming licenses from the Department of Environment and all stages of breeding and rearing are carried out in full compliance with environmental principles.
