Can anyone tell me what this has to do with freshwater aquatic plants? Don't get me wrong, I'm not a proponent of killing any animal, but I barely have time to read all my e-mails now. The APD pleasantly remains on-topic most of the time (at least in the two years I've been lurking). There, I'm done (climbing off soapbox).
