I live in Erieau on the north shore of Lake Erie . Every spring living on the lake shore I see hundreds and hundreds of cormorants flying by my house as well as in Rondeau bay , They have started to roost in trees across from our pier and are killing all the trees with there droppings . I have no proof but in the last few years perch are not being caught in numbers . I talk to the commercial fisherman and they say the perch are getting harder and harder to find . I feel that a hunting season would lower the birds numbers and save our fish species . I have heard stories that these birds are eating all the fish in the smaller lakes in our area .
