Gregoire Posted May 23, 2017 Report Share Posted May 23, 2017 I went down to the lake Ontario waterfront yesterday, and while I was dragging a large rubber lure hooked in to a few 3 spined stickle backs, and was wondering if they are invasive to Lake Ontario and if I should be contacting the MNR?

John Bacon Posted May 23, 2017 Report Share Posted May 23, 2017 I think they are native to Lake Ontario. They are definitely known to be in the Lake. http://www.ontariofishes.ca/fish_detail.php?FID=120 Link to comment Share on other sites More sharing options...
Gregoire Posted May 23, 2017 Author Report Share Posted May 23, 2017 I have done a bit more reading. It seems like you are correct. It just struck me as odd, as I had only seen this type of minnow in salt water before yesterday. You learn something new every day. It looked like the cormorants were gorging on them.

dave524 Posted May 23, 2017 Report Share Posted May 23, 2017 Most of the Sticklebacks I've seen, we caught in minnow traps in Haliburton in streams and beaver ponds, usually pretty cool water streams some of which had Specs in them. Not sure if they were the same species though. Link to comment Share on other sites More sharing options...

Not sure if they were the same species though. Different species. The ones you saw would be Brook Stickleback (which usually have 5 spines). There are also Ninespine Sticklebacks, and Fourspine Sticklebacks (which are invasive but only found around Thunder Bay) Link to comment Share on other sites More sharing options...
