Foreign species of fish that have been damaging the Lake Biwa ecosystem in Japan will now be turned into petfood, according to The Mainichi Daily News .
In the past, the 400 to 500 tons of fish retrieved from the lake were only used in livestock feed, but due to the presence of vitamin E and taurine in the fish, it was suggested by food analysis company Hiyoshi to also use the species in petfood.
A company on Lake Biwa's Okishima Island started developing a fish-based product with Hiyoshi in February.
The petfood consists of black bass and bluegill fish and can be used as dog or cat food.
