Asian carp. Not good news.

The men contacted biologists from the Quebec Ministry of Forests, Wildlife and Parks.  They came quickly he said, and were greatly surprised, adding it was if they didn’t want to see it, but were glad it was caught.The biologists were not happy because it turned out to be an Asian grass carp, an invasive species which grows and reproduces rapidly and is a voracious eater.  It’s the first Asian carp found in the St Lawrence.
Grass carp is one of four species of Asian carp, which have been wreaking havoc in American waters and pose serious threats to native species.
The grass carp species eats vegetation and can destroy the habitats of native fish where they lay eggs and where young fish can hide from larger predators.
