I don't fish but I dive and a question that was asked to me by a fisherman is why I'm not spearing Gobys when I'm diving. Is spearfishing gobys legal in Lake Michigan. This guy has a major obsession for killing all Gobys.
 
I dove the Fleetwing in Door county in October. The bottom was literally carpeted with Gobies. I think they are eating the zebra mussels. There are alot of empties(zebra's) and I observed the gobies sucking up the schells and spitting them out. If they are eating the zebras that would explain thier population explosion, the empty shells and the degrading viz we seemed to have this year. I think the gobies will be around for awhile, but like the zebra's they will outstrip thier food supply and nature will find an equalibrium.
As a diver, settle down on the lake bottom and remain as still as possible. After a few minutes the gobies will resume thier activities as if you aren't there. Some will gather around and watch the large bubble emitting object in thier midst. There will be a few who will stake out an area the size of a pie plate and defend it. Great fun to watch. I spent an hour more then once at the deep section of the Fleetwing just watching them interact with each other.
Getting back to the original question. There's not enough fish in a single gobies to make it worth the effeort to spear. At best, if you could net a few hundred and clean them like smelt, deep fry those little suckers in a beer batter, you might have something. With a little luck the salmon, bass, northern pike or perhaps muskies may decide that gobies taste good. That would trim thier numbers pretty fast. In the end, only Ma nature knows for sure.

Hay,
There are a lot of nice fish in Gilboa;

But I do not think you would make Mike to happy.

I figure the next time there is a GOBZILLA contest I could just dive down and spear me the biggest goby I see. The last contest here paid $500 for the biggest one. There was also cash paid out for the most pounds caught. They filled a big dumpster full of the little invaders.
The gobies do eat the zebra mussles and now the zebra mussles are disapearing.
The salmon are not bottom feeders, they won't eat gobies.

Zebras are disappearing? That's a new one on me. I would scrap mussels off of a wreck and watch the gobbies go after them, but thought there were more than enough to go around!
 
I was under the impression that Gobies were toxic from eating the zebra muscles. I'm sure the fishermen have some reason for not liking them. Question is one exotic spiecies eating another exotic species a good thing or a bad thing.

I've also noticed that the number of zebras seem to be falling, at least in Whitestar. Not sure why, I don't think I've seen any Gobies there. Might be they were buried in all the silt from the new divers.

Funny how most of us can pick out issues with a tropical reef, but we dont' know much about the fish in our own backyards. Mostly because we never see them.
