This is a tough one. In my opinion, I don't feel some people really care about the impact this is having on our native species when it comes to the fish,or it seems like they couldn't stop it, so they are trying to make it sound "not so bad". Gobies out spawn our native fish immensely. That seems to be a serious issue when looking at all the problems facing us anglers today, and future generations. When spawning they become very territorial and voracious. They have been witnessed destroying salmon, bass, and trout eggs in minutes, and sometimes by the tens of thousands. Unless our fish increase spawning habits, I don't see them competing as well as we hope.
This is just my personal opinion.
I've watched the animals adapt to these creatures over the last 6 years in Lake Ontario alone. The birds dive bomb them like mad now, the fish have started to eat them, animals like mink and weasel help out a lot, especially mink, with their impulsive, kill it if it moves behaviour around the rocks and shore lines. But the gobies numbers are still hitting amounts of up to 100 per square meter of Lake. I wouldn't doubt that the number is more in some locations, just from what I've seen in places like the credit River and certain harbours and rivers on the north side of the lake.
They've spent millions on research and prevention over the years all over North America. (from what I've read any way ).
But the gobies are still here. The article left out the problem with parasites and botulism I believe. That will probably be something to think about while everythings eating them.
I'm not saying I'm right. But I sure hope we have something left for our children to experience through their life. I hope whoever is doing this research and promoting it, wants the same thing.
