Additionally, arapaimas are air-breathers, a feature that could help them survive even in polluted habitats. These post-flood field surveys revealed that fishers had caught arapaima and gar from four flood-affected rivers in Kerala: the Periyar, Muvattupuzha, Kurumali and Chalakkudy. “However, there is no data on this, as most of the farms that were growing these fish are illegal and no one has background information on the number of fish stocked in these ponds along these flood plains.”. Arapaima is a non-migratory fish and it’s stationary in the Amazon River; the Arapaima hunts and swims within a 100km radius of its birth location. Kerala’s flood ‘fugitives’ Kerala’s river systems, which the authors study, are home to around 200 species of fish, 30 percent of which are endemic to the region.

The fish can measure up to three metres in length and could put the native fish species at risk. The mouth is turned upwards which helps with feeding as they consume food from the surface. It measured six feet long and weighed a whopping 41 kilograms. London: Reports indicate that the arapaima, a giant species of fish that lurks in the Amazon river, may be threatened by overfishing. But the larger problem of aliens turning invasive is not restricted to Kerala’s waters alone. It was 7 September, barely a month after the floods of 2018 had wrecked large parts of Kerala.

Kumar, who documented how ornamental exotic South American suckermouth armoured catfishes (genus Pterygoplichthys) were invading the drain networks of Thiruvananthapuram city in a study in 2015, found that traders and aquarium hobbyists were releasing these fish into drains when they grew too large for their aquariums or tanks. The Arapaima is also known as the Pirarucu and originates from the Amazon Basin in South America.

Another new species spotted in Kerala's newly-calm waters is the Arapaima (pictured), a vicious predator of Brazilian origin known to survive out of water for a considerable amount of time. Physical removal of catfishes from these areas would also help counter the situation, he suggested; in Periyar, the NBFGR along with the Periyar Foundation has taken up a programme to remove African catfish from the lake by involving tribal fishermen, he said. In their communication in the journal Current Science in May this year, the team call for an urgent nationwide scheme to eradicate such alien fish species. And the team recorded only six arapaima and gar in total: a number that seems barely enough to ‘threaten’ river systems. But unless we know the numbers of these aliens in our river systems or their reproductive status, it would be impossible to make predictions, he added. This fish was featured in the first episode of Jungle Hooks made in 2002, where Jeremy Wade attempted to catch this fish on camera. Some species may need to be addressed specifically.
