bucket biologist
n.— «The balance of nature in every lake is so fine that an ignorant bucket biologist has the potential to plunder and vandalize a fishery.…Bucket biologists are hard at work all over the country. Walleyes are being dumped into Montana lakes. Rainbow trout are destroying native brook trout fisheries in the East.…Bucket biologists are ignorant, selfish people. If professional biologists make mistakes—a case in point is the introduction of stripers at Lake McConaughy—how can the bomb-like buckets of amateurs not explode?» —“‘Bucket Biologists’ Stir Up Problems” by Larry Porter Omaha World-Herald (Nebraska) Oct. 23, 1994.
