Re: E-M:/ Unwanted snakehead invades Arkansas - Potential Great Lakes problem

Enviro-Mich message from Larry Nooden <ldnum@umich.edu>

How about fresh water jellyfish from China (Science 317:1839, 2007)? These apparently came in with aquarium plants from the Yangtze River valley.

Regarding snakeheads, there have been several observations of in natural areas along the US east coast over the past several years. This is old stuff.

More information at the International Nonindigenous Species Database Network website:

Is anyone minding our environment or even our safety (that includes food and drugs)? Is anyone applying common sense?

A skeptic would have to say no, and the Katrina response, poisoned gluten food supplements, poisoned heparin, etc. could be offered as evidence, but that is getting off-topic. A skeptic might also conclude that the movement to eliminate government is aimed at these inconveniences for special interests.

I would guess that many knowledgeable government employees would like to help, but they are simply (deliberately?) understaffed and overriding by politicians. I believe this applies to MDEQ and the Army Corps.

Being an optimist, I hope some political reform/change is on its way.

Unwanted snakehead invades Arkansas

The northern snakehead, an aggressive fish native to Asia, has been found
in Lee County and could colonize the lower White River basin.

?This is some of the worst news we could get as fisheries biologists,?
said Mark Oliver, assistant chief of fisheries for the Arkansas Game and
Fish Commission. ?We can see looking in their stomachs that they?ll eat
everything that?s out there. They?re eating crayfish and bream, and
they?ll kill fish just because of the competition factor. From the White
River, they have access to much of the state.? Lee Holt, district
fisheries biologist for the AGFC in Brinkley, confirmed a breeding
population of northern snakeheads April 28 in a drainage ditch in Lee
County. Oliver said a farmer found the first one about a week ago on the
ground near a drainage ditch. Since then, he said AGFC personnel also
found adult snakeheads, including three that measured 20 inches, 17
inches and 14 inches long, respectively.

?Unfortunately, all these creeks are way out of their normal borders,?
Oliver said. ?Once they?re out in the streams, there?s no way to do
anything about them. The water?s too cool to rotenone them, and there?s
too many places for us to miss them.?
