There seems to be a bit of a split in the sport fishing community, between those concerned with depleting stocks of native fish and preventing new introductions, and those that just want to fish and are happy to let the government continue to stock bodies of water with species like the northern pike (Esox lucius). In Maine, angler Bob Mallard recently published this piece in the Kennebec Journal, addressing the DIF&W's policy of managing illegally introduced fish species in major bodies of water. Bob also has a forum at the website for his store, Kennebec River Outfitters, where you can find a lot of posts from anglers with similar concerns. You can also read Bob's recent article in the Northwoods Sporting Journal. By the way, "Bucket Biology" refers to the illegal introduction of species into bodies of water by transporting them in a bucket.
