{Tidal Potomac Fly Rodders} Re: Snakeheads may be wreaking ecological harm, after all

Yeah, the headline isn't really supported by what is said in the article.  I'm not absolving snakeheads of anything just yet, but the discussion in the article brought up two things that could have negatively impacted fish populations at Blackwater even if it was snakehead free: 

1.) At some point (article doesn't say when), a dam was installed to block saltwater intrusion. Then they blame the decline in yellow and white perch on snakeheads, but it seems like loss of ability to freely migrate would have a pretty big impact.

2.) The biologists for MDNR admit that low oxygen levels the previous year probably killed a lot of fish of many species. So they're saying "Here's a major, obvious cause of fish mortality that wasn't snakeheads, but we're going to go ahead and blame them anyway."

I don't think enough time has passed to definitively say that snakeheads aren't having negative impacts, but the article failed to bring any sound evidence to make me think snakeheads are "wreaking havoc".

I'll let Andrew chime in as we were discussing this piece a few days ago after he shared it with me, but my initial thought was that it's odd to recognize how we all may have jumped to conclusions too early and then turn around to fan the flames of early conclusions without looking at all environmental variable again...

Additionally, they should probably look at the other factors that they brushed over instead of just focusing on the snakehead...

Some disagreement about the impact of snakeheads between experts from MD and VA.
