Re: More on Crawfish
Trees might grow better with an artificially lengthened photoperiod but that doesn't necessarily translate to animal life. I believe one of the first posters mentioned that crawfish were photo-sensitive and therefore only came out to feed at night. If you artificially light the shoreline would they fail/refuse to come out to feed? If so, they could starve or simply fail to reproduce. Option two would of course be that they travel to someplace with out lighting. Again just a theory for any bored grad student out there to play with.
And yes, I believe that the crawfish is in the same family as the lobster which I believe puts it in the same family as the cockroach, a bug.
