A Japanese science professor has announced that he has found a Japanese salmon fish species thought to be extinct 70 years ago, alive and thriving in a Lake near Mount Fiji.
The species known as the "black kokanee" was thought to have died back in 1940 when its native lake in northern Akita became acidic due to a hydroelectric project. But now the science professor along with his team of researchers have claimed to have found the salmon alive and well in Lake Saiko.
The professor posed along with the salmon for pictures to make his claim valid. The species is also called "kunimasu" in Japanese and can grow to a lenght on 1 foot. It is dark olive in colour and has black spots on its body.
An official at the Environment Ministry said that the claim of the existence of the fish will be further investigated before the fish is removed from the list of extinct species.

One such eel was caught upstream of the dam recently and it weighed about 10 kilograms.
Damming the rivers destroys fish ladders and tends to hinder eels and other freshwater species of fishes from going down the delta to lay eggs and multiply.
