NGT: National Green Tribunal formally banned the Thai Mangur. It is a catfish that was harming the local ecosystem and the consumers’ health. It is favoured by the cultivators due to its ability to feed on anything and survive in hostile conditions. It also has high demand because it is cheaper when compared to other seafood. Recently, thousands of tons of this banned catfish were found to be illegally bred in over 125 artificial ponds in rural Maharashtra’s Thane.

Why NGT banned Thai Mangur?

In 2000, the NGT banned the cultivation of Thai Mangur. This was mainly because the fish poses threats to other fishes in an ecosystem. According to the NGT study, the Thai Mangur is responsible for 70 per cent decline of native fish species of India. Also, the fish in certain states of India such as Maharashtra is being cultivated in unhygienic conditions posing health risks to the consumers. Thus, the NGT banned the cultivation of Thai Mangur as it began to pose threats to the people and environment.

Thai Mangur cultivated illegal

Maharashtra Government has destroyed more than 32 tonnes of Thai Mangur. In September 2020, the Uttarakhand Govt pulled up several fish farmers for cultivating Thai Mangur illegally.

In spite of several legal measures and bans, the species is being cultivated illegally and its sales are popular mainly for its surviving capabilities. The fish can grow even in muddy waters between the rains. Also, it grows three feet to 5 feet weighing three to 4 kg in just 2 to 3 months. It is a freshwater air breathing fish. It has the ability to wiggle on dry land to find food or suitable environment. It lives in stagnant or slow-moving waters. It has an omnivorous diet, ability to survive on land and ability to hide in vegetation. These characteristics make the cultivation of the fish easy, highly profitable and economical for farming.
