DeGasperis Fri, 27 Nov 2009 13:15:40 +0000 http://greatlakesecho.org/?p=9968#comment-2938 Like I said before "big fish eat little fish" 4" Walleye and Perch feed on 1" Alewife! I read a study from our OMNR. back in the late 80's they found in Lake Simcoe Perch were feeding on Walleye fry in prime walleye spawning areas. Not that I am a big fan of Alewife but they are in the mix and not much can be done about it. Like I said before “big fish eat little fish”

4″ Walleye and Perch feed on 1″ Alewife!

Dan Thomas says there's bias for native fish, there's supposed to be! If you really want to restore the biological health of the lakes both the Alewives and Salmon gotta go!

In Ontario years ago it was stressed by our OMNR. not to transport smelt or use them as bait in other body's of water, along with any other specie's these days.

DeGasperis Thu, 10 Sep 2009 12:50:38 +0000 http://greatlakesecho.org/?p=9968#comment-1543 This is the first time I ever heard that Smelt were stocked into the Great lakes, can anyone else say they know this or is there a way of finding out the details behind it. I always read that Smelt were introduced by way of ship ballest water. From what I see the Lake Trout eat smelt as much as they can. With warmer average water temp's, pollution, Zebra mussels, Gobey, these all effect the reproduction of Lake Trout and Ciscoe. Even if some Lake Trout made it to adult spawning age the commercial fishermen would keep the stocks low and don't forget the cormorants.

By the mid 1950's they destroyed the blue pike, lake trout, ciscoe, whitefish and other coldwater fish stocks. They did this by consuming all the fry and fingerlings in the colder lake waters. There was no survival of these species at that time.In the mid 1960's the Canadians started trawling for their commercial fishery of the smelt and then the sport fishery started up.

It's the other species that have really declined. The alewives have even begun to decline the perch population and the smelt are no longer around. I think it's time to introduce some cohos, kings or stripers because our lake is only good for bass now. Lake trout fishing is phenomenal on lake champlain.

I empathize with your situation. There are no easy answers, and they are all interconnected. I think until we first address the major habitat degradations and encroachments, we will forever be chasing our "tails." New species naturally move into new habitats, expanding their ranges. The fact that humans have assisted in this migration as opposed to a duck, for example, leaves us with the social consequences with which to contend, such as your local economy now dependent on an exotic fishery. Do we rid all the East of the rainbow trout and all the U.S. of the brown trout? I think we know how the majority might respond to that question. Your situation seems to be much the same.

The folks I’ve talked to haven’t blamed alewives so much for the lake trout collapse. That was the sea lamprey and overfishing, though there’s a debate over which one hurt most.

Instead, they say alewives are an obstacle to bringing lake trout back.
