dont know about fish, but here we have bush honeysuckle, it drives me nuts, although i don't think anyone else notices it.. its almost impossible to get rid of once its established!!!
recently fireants have jumped north to nashville, and are spreding from their origen point, southern shrubery that was planted around a new mall... there is no way that the planters did not notice the ants, but noone cares, so long as they are payed!
starlings are everywhere...
asian beatles are killing all the pines around here... and i really wish that i could go back in time and see the white summer that chestnut trees used to cause before the chestnut blight... in the eastern united states, these trees were sometimes as common as 1 out of every 4 trees! now there are only a handfull left!...
then there is kudzu... and a bunch more stuff!
and yea, amazonian snakes are invadeing the everglades, althogh they really just replace the role that the aligator playes, i dont think they will do much damage... but still, its another example on how things change!
the european starling was introduced when a shakespere club decided that they were going to bring all animals listed in shakespere to the new world, there was one passage that mentioned starlings, and they purpoisely brought a male and a female over, cherring as they made a nest in the corthouse eves... it makes me sick!!!
