Smallmouth bass and sunfish have been dying in the Shenandoah and the Potomac in Virginia for a few years, and despite lots of research, no one knows why. Washington Post reporter David Fahrenthold writes in this morning's paper that scientists are still perplexed about the death of thousands, maybe even millions, of fish. They've looked at the usual suspects -- poultry manure, algal blooms, infections -- but they're still dealing with a mystery. A nice story. And while we're on the subject of the Post, they gave us credit for breaking the story on the natural gas pipeline that would run under the Chesapeake Bay. Occasional blogger and Eastern Shore reporter Chris Guy gets the credit for that one, which he turned around very quickly.
