Have you noticed that many credible articles about the reason for decline of the Ozark Hellbender seem to be trying to divert our attention to reasons other than the introduction of trout. FWS is saying that their decline is due to increased siltation, water quality degradation, and increased impoundments. No mentioning of trout. Now the big reason is an infectious disease called "chytrid fungus" which is thought to be the reason for hellbenders missing appendages. The introduction of trout as the reason is rarely, if at all, mentioned in any article that I've read.
