was caught by a fisherman Andy Alder in Lincolnshire.
“It had a gob full of razor-sharp teeth. To be honest it looked terrifying.”
The fear from conservationists is that the fish could invade the waters killing off native species. It is considered the ultimate invasive species. This fish can survive even out of the water for up to four days.
The fish was believed to have been smuggled in for an aquarium and released illegally into the waters.
