In the most recent issue of the journal Science that I have is a 5-page article on efforts to find and conserve big freshwater fish species, bigger than 6 feet long and two hundred pounds. Two of these species are North American, the alligator gar and lake sturgeon. Most of these species are in trouble, such as the Mekong catfish, because of overharvesting and habitat degradation.

I have a .pdf of the story and I'm willing to send it to people if you contact me at: fundulus at hotmail dot com. And no, I don't have any of these fishes to give anyone....

Wow, those Mekong catfish become huge! Are the Wels catfish in trouble also (in asia)?

I think that the Wels are less numerous than before, purely due to habitat degradation. Major European rivers like the Rhine and Danube have been horribly polluted for a long time which isn't good for any fish...

factnfiction101 asked about wels catfish in Asia. In China, the wels catfish (Silurus glanis) is rare, but not because of people but because it isn't naturally distributed there. However, in central asia, wels catfish are not as rare. On the IUCN red list the wels catfish is considered "lower risk/least concern".

In Siberia, China, Korea, and Japan there is a closely related species, the Amur Catfish (Parasilurus asotus). It is fairly common.

I always thought that the blue catfish was the largest North American purely freshwater fish. (Admittedly, the evidence is anecdotal.)

No, the alligator gar is still the longest, certainly, and probably the heaviest. I heard over the weekend that fisheries managers in Illinois are resisting the reintroduction of alligator gar to parts of the original range in southern Illinois for fear of its voracious appetite. These are people with a puny plan, to quote my friend The Humongous.

Hmm. Road Warrior was on just the other night, and Alligator gar appetite fear is silly. I hope you set them straight.

Out of curiosity, what are they frightened of?

I didn't speak directly to IL managers, just to someone who has been on the edge of the decision process and isn't in a position directly to naysay them. The fisheries people are purely and simply scared of alligator gar eating all of the bass, sunfish and whatnot. It's stupid but they seem to be programmed to respond that way since it's serving their perceived role. It would be an interesting local agitation in favor of alligator gar reintroduction that would require some education. I don't think the issue has been introduced in a public fashion, more like staff biologists talking back and forth.

Hmmm...something new to work on in my spare time...
Honestly was was not even aware of this being discussed...For that matter it seems us 'tens' of Gar fishing fanatics have not even heard of this...Well well.. more stuff to begin fussing about other than getting the gator on the sport fish list in Texas :P

Neat article! I didn't have a chance to peruse the latest issue yet. Thanks for the heads up :)
