Northern Pike were placed in Davis Lake and Frenchman's Lake, California not too far from Reno (NV). They had devastated the trout fishing. It appears that poisoning has had only limited success in removing them. There are big worries that these pike will find their way down through the Sacramento River system and further damage the almost ruined Pacific salmon runs. I wish the upper Midwest mental cases who brought these eating machines would get good and drunk, fall overboard and breath in big gulps of water...then feed the crayfish!!
