The effect of invasive species on the Great Lakes is the focus of a House Transportation and Infrastructure subcommittee hearing tomorrow, Wednesday (March 7), at 2 p.m. in 2167 Rayburn, Washington, DC. A subcommittee briefing paper from the 109th Congress noted that a new invasive species is discovered every eight months in the lakes.

The White House fiscal 2008 budget includes $35 million for the Great Lakes Legacy Act that funds U.S. EPA partnerships with local agencies and $8 million for an invasive species barrier on the Chicago Sanitary and Ship Canal. The Great Lakes boasts 18 percent of the world's fresh water supply and 95 percent of the U.S. fresh water supply. The system is the source of drinking water for millions, supplies process and cooling water for industrial uses, and is used to generate hydroelectric power.

Sen. Carl Levin (D-MI.) introduced two bills last week aimed at reducing the invasive species threat -- the "National Aquatic Invasive Species Act" and the "Asian Carp Prevention and Control Act."

The National Aquatic Invasive Species Act would reauthorize and strengthen the National Invasive Species Act of 1996 to protect U.S. waters by preventing new introductions of aquatic invasive species. The legislation would regulate ballast discharge from commercial vessels, prevent invasive species introductions from other pathways, support state management plans and screen live aquatic organisms entering the United States.

The Asian Carp Prevention and Control Act would list three species of Asian carp -- the bighead, black and silver carp -- as harmful wildlife under the Lacey Act. The move would prevent the intentional introduction of these species into the Great Lakes by prohibiting the interstate transportation or importation of live Asian carp without a permit. The Lacey Act makes illegal the trade certain fish and wildlife.

According to Levin's office, estimates of the annual economic damage caused nationwide by invasive species range as high as $137 billion. Because the Great Lakes fisheries are valued at $4 billion annually, preventing invasions into the Great Lakes from ballast water, hulls or the system of canals connecting the Great Lakes to the Mississippi River and Atlantic Ocean is critical. Once an exotic species establishes itself, it is almost impossible to eradicate and usually difficult to prevent from moving throughout the nation.

Asian carp have yet to enter the lakes, but scientists have spotted the invasive species within 25 miles of the entrance to Lake Michigan. The fish, which can weigh up to 60 pounds, migrate up the Mississippi River to the canal, where the fence emits an electric pulse to repel them. While Asian carp do not eat other native fish, the species eats up to 40 percent of its body weight in plankton each day, out-competing other species for food and habitat.

Good stuff, thanks for the update Lucky Dog :D

I hope they do the right thing and make sure them bigheads don't make it into Lake Mich. I have a bad feeling it's going to happen at some point though. It seems as if people are too ignorant to act before there is a problem and only when you have a major catastrophe do the reactionary response's begin.

The best way to fix a problem.....................prevent it from ever happening :wink:

believe it or not, i just found out that bass were stocked in Korea several years ago as a sport fish and now they are over taking the native species. they are now considered an invasive specie. it's illegal to release a bass in Korea. LOL!

that'd be so hilarious if a world record bass was caught in Korea! LOL! :shock:

I just decided that the March WCF tourney will be held on Wonju lake, Korea. If you can't make it you will be automatically disqualified.

Biggest difference Augy is the appetitite's. If they are having a problem with the bass taking over that means they can't be getting very big so they're getting a bunch of 1/2lb-1-1/2lbers. We have the same problem here in teh states, Bass over-population results in an undersized population.

You comparing grapes to watermelons.......................

The Big Head Carp has an appetite rivaled by few(I know you old enuff so think of what the old WWF guy Andre the Giant used to eat compared to 3rd grade child). I remember reading he would have something like 6 eggs, 6 pancakes, 1/2 gallon of milk, plate full of sausage and bacon. And that was just his breakfast.

They initially cause 2 problems with their presence.
Diet & location.

Diet:
First they are filter feeders and eat zooplankton, same stuff that the baby/mini fish need to survive. Factor in these fish can be 20,30, 40 pounds or more... Plus that same food is required by many other critters living in the water ecosystem.

So a 30 pound fish is eating the same food as a fish <1 inch long is a huge problem. Plus the numbers are staggering, millions are estimated in the Illinois river. One Big guy eats maybe 500-1,000 x more food per day. Thats like having 100 older brothers/Andre the Giants eating breakfast before you...

Location:
Just the size and number of these fish is staggering. They share the same spots with the bass & walleye, thus pushing the smaller fish out. The "native" (don't go there, thats another thread) fish are forced to find other habitat, farther away or secondary/tertiary for food.

Its a stress on the current fish populations for food and habitat.

Get into Lake Michigan?
Thats an unfathomable problem we can't adjust to...

I keep saying...
Start using zoo plantkton on your down riggers.
Because carp will be #1 and not salmon..

But, I have heard many "users" of the fish that the meat of the asian carp is different vs. regular carp because of their feeding process and that its actually very good smoked. I tried bowfishing this past spring, and plan to do it again this summer.

I also plan to bring one home and try the meat myself..
