Chronicle Reporter, Bhopal, The decision to breed Taiwanese fish ‘pangasius pangasius’ in the millennia-old Upper Lake has been opposed by the experts who claim that breeding of the foreign fish will have long-term adverse impact on the lake’s ecology.
So far fish like Rohu and Samal are being bred in the lake, which is the first man-made lake of the country. Drinking water is supplied through this lake to the city.
Experts say the rearing of foreign fish in the lake cause irreparable damage to its environment.The impact can be understood by an example that the water in the Upper Lake around the medical college had recorded a total 69 different phytoplankton species in 2005.
Fish production and fish productivity from aquaculture and fishery resources of the inland would be demonstrated, said department of fisheries director OP Saxena.
Experts say that breeding of fish, which is not from the same native environment, can cause long-term damage to the lake, which is a protected site under the UNESCO Ramsar treaty on wetlands.
