In our streams in pa the fish commission targets the muddy bottom creeks and trys to kill the spawn before the population gets out of wack.
They get bigger than you guys think I saw one last fall that was hanging off a steelhead that was at least 18'' if not more it was sick because the fish was maybe 28''. I think it would be horrible swimming upstream trying to spawn and have that thing hanging off my side.
Um...did you even read the rest of the thread?
There are more than one species of lamprey...
Not even all feed on fish in fact...
