Discovery of a fish species referred to as Alligator gar in Neknampur Lake has set the alarm bells ringing for the biodiversity of metropolis lakes.
An NGO ‘Dhruvansh’, which has adopted the Neknampur Lake, has found three lifeless members of the fish species within the lake and raised considerations about the identical, as a result of they don’t seem to be native to India. “These fish should not present in Indian rivers and lakes. They’re grown for aquariums, and once they turn into too massive to deal with, folks go away them in lakes,” mentioned conservationist and lake activist Madhulika Choudhary, the founding father of Dhruvansh.
Alligator gar are naturally present in North America, and introduced right here on the market as aquarium species. They will develop as much as a number of toes in size, which ultimately makes them unfit for aquariums. That’s when the house owners and aquarists, unable to accommodate them and feed them any extra, go away them in metropolis lakes.
“We discovered three, as a result of they’re lifeless. We don’t know what number of such fish have been left within the lake. They’re predatory in nature, and may wipe out the complete lake of its biodiversity,” says Ms.Choudhary.
Farida Tampal, State Director of WWF-India, says aquarium species being left in metropolis lakes has turn into a menace of late. “I’ve come throughout an occasion the place an Alligator gar was left contained in the Lotus Pond. There is no such thing as a management over which type of fish are being introduced from exterior and the place they’re being left. Proof means that even extraordinarily predatory species reminiscent of Piranhas that are being grown by aquarists right here,” Ms.Tampal says.
One other invasive species which is being present in metropolis lakes is the Pink eared terrapin/turtle. “A member of this species was present in Neknampur Lake earlier. They’re aggressive in nature and kill different pond turtles reminiscent of pond terrapins and flapshell turtles. Unique species are harmful for native ones. If you happen to can’t take care of them, why do you retain them,” asks Ms.Choudhary.
