So we learned more about the different types of carp, and how they are dangerous to fish in Ontario.
Then we took a look at some of the other invasive species of water critters in Canada.
Round Goby (this we have seen, caught and killed) zebra mussels (have brought these home to study), spiny water flea, rusty crayfish, sea lamprey (have seen pictures of), bloody red shrimp, Eurasian Ruffe
And the rest we looked them up.
The Spiny Water Flea - here's a link. They eat the food native species need to survive.
Rusty Crayfish - here's a link. These critters have aggressive eating habits.
Eurasian Ruffe - this one surprised me, I thought from the name it was some sort of small critter, but it's a fish. They compete with perch and reproduce rapidly. Here's a link.
It was eye-opening to the lad and I just how many invasive species there are in Ontario. Not just water critters, but plants and other living creatures as well.
