Tilapia fish banned in 1959 still occupies lakes and reservoirs


Tilapia fish, native to Africa, was banned in the country in 1959, but it continues to flourish and has overrun lakes and reservoirs. It is now occupying every single water body in Chennai and is elbowing out many native species.
This is reported in thehindu.com dated 9 November 2016.
This variety of fish is a perennial breeder and can tolerate pollution and it has eaten into resources that earlier were shared by several other species. The tilapia can survive in water with very low oxygen level and its eggs retain life even in dry conditions. It is believed to have destroyed the habitat of native species which are already decimated by pollution.
The Fisheries Research Committee of India had imposed a ban in 1959 on one species of tilapia that was introduced in 1952.
However, the Nile tilapia introduced in 1970, became an important component for aquaculture in India and was known as the ‘aquatic chicken’. The National Fisheries Development Board in 2015 issued guidelines for responsible farming of the fish.
