Wed, 07 Dec 2011 00:34:40 +0000 http://greatlakesecho.org/?p=17803#comment-21756 Humans polluted the lakes with too many nutrients, known as eutrophication. This caused an overgrowth of phytoplankton. Zooplankton eat phytoplankton and they too exploded. Small fish eat the zooplankton, and they too exploded. To combat this ecological imbalance, an apex predator population had to be reestablished. But the native trout and salmon couldn't cope with the pollution, so we introduced pacific salmon, a non-native species. Of course they did wonderfully. If any of you have any science or ecological understanding, non-natives can also become invasive. Technically all of your sacred sport fish, your pacific salmon, are non-native invasives. It seems that all you care about is fishing, a silly sport. Yea, its a multi-million dollar industry but its hanging on by a thread. We created an artificial ecosystem that is not sustainable. Soon there will be no fish for any of you to catch. Oh and I hope you haven't been eating them, they are loaded with mercury among other things.

We also noticed a decrease in striped bass sizes and numbers. Could this pattern and condition be also applied to the Great Lakes situation? Should we be patient and adjust or is it imperative to intervene? Is it legal to use an under water light to attract zooplankton, then alwives, then preditors. Then catch the alwives and use them for bait while the light is still lit?

Alewives eat the same thing Asian carp do, (including native larval fish) for 4 months of salmon fishing (good or bad)we sacrifice 12 months of good fishing for native fish as alewives hog the zooplankton and eat the laval fish. Protecting the alewives makes lake michigan safe for all invasives and the asian carp. Perch and walleye also eat alewives and salmon are not required to control them. They just inmply only a salmon can. Salmon cannot feed where baby asian carp will be, so thier useless. I see full boat launches in Saginaw bay catch limits of walleyes i see empty boat launches in west michigan. Trying to control nature never works. The asian carp just came out of Door no. 3 and we will all pay dearly for it, all because of the alewife protection plan!

Gobies are shallow water bottom dwellers. Both salmon and alewives are pelagic species living generally in the middle of the water column over deep water. Gobies have become the prey of walleye, bass, pike and to a certain extent some trout species. Gobies will not replace alewife as salmon prey. Gobies are shallow water bottom dwellers.

Alewives are invasive to many lakes, but native to Long Island. Why would people introduce a Pacific salmon (possibly viewed as another invasive, the Atlantic salmon has shown a decrease)to control an invasive. I can't wait to see what is stocked to control big headed carp!!! It is simple… Alewives are invasive to many lakes, but native to Long Island.
