Mr. Hammond needs to do some fact checking, too. Lake trout are in fact native to Lake Champlain though they seem to have been extirpated during the 1800’s (see Strategic Plan for Lake Champlain Fisheries, Great Lakes Fishery Commission, Miscellaneous Publication 2010-03). I’m pretty sure that 99% of McDonalds fish sandwiches originate as native Alaskan pollack in the Bearing Sea. Yes, common carp have been here for decades. Just think if all the common carp biomass were converted to perch or walleye or bass?
Finally, Mr. Hammond is confusing non-native vs. invasive. Non-native is just that – plants or animals not originally occurring in the ecosystem in question (i.e. brown trout in North America, rainbow trout east of the Rockies). Most non-natives cause few problems (rainbow trout are a good example, but it should be noted that brown trout continue to negatively impact native brook trout populations in some Adirondack streams). Only when a non-native “causes or is likely to cause economic or environmental harm or harm to human health” do we apply the term “invasive.”
