The sea lamprey is a primitive, eel-like fish native to the northern Atlantic Ocean and the Baltic, western Mediterranean and Adriatic seas. They invaded the Great Lakes in the early 20th century through shipping canals. The sea lamprey uses its sucker mouth, sharp teeth and rasping tongue to attach itself to the body of a fish and suck the fish's blood. Fish that survive the attack are left with a large open wound that can become infected and often leads to death. The jumping ability of adult sea lampreys is limited, so barriers function to block adult access to spawning habitat and, therefore, reduce the amount of habitat that sea lampreys can infest. I'm linking to Lesley's Signs, Signs.
I had forgotten about these lovely creatures, thanks for the reminder.
ReplyDeleteI had never heard of this fish, a rather nasty one when I read how he treats his fellow fishes.
ReplyDeleteThat sign you don't see everyday.
ReplyDeleteHoly Jumping Eels! :-)
ReplyDeleteI had no idea. Thanks for this. Most interesting. Those sea lampreys remind me of some bankers and Wall Street brokers I've heard about.
ReplyDeleteSounds like a rather scary creature. I love Lowell's analogy.
ReplyDeleteNever knew about the sea lamprey. Thats good info.
ReplyDeleteThey are nasty creatures, Andy!
ReplyDeleteIs that good or bad?
ReplyDeleteHmmmm The description reminds me of certain people running for office....
ReplyDeleteSounds like a clever solution to the problem, I hope it works.
ReplyDeleteGood to take steps to thwart them.
ReplyDeleteI've never heard of these! The fewer the better!
ReplyDeleteOoh. Looks scary.
ReplyDeleteThat sounds like a totally evil creature. Yuk! Hope the barriers are working.
ReplyDeleteI've never seen one, but would like to. In the proper place, of course.
ReplyDeleteNever heard of that one before. I can understand why they need to be controlled.
ReplyDeleteIt is difficult to get rid of these invasive creatures. I am assuming that these structures are going to work.
ReplyDeletewe are losing the ones we so want to live and reproduce, and getting the ones that do more harm than good. Looks like the powers that be are on the right track. I certainly would hate to be bitten by one. UGH!
ReplyDeleteI appreciate the efforts.
ReplyDeleteFrankly My Dear
EW!!!
ReplyDeleteWow never heard of that. I am a Canadian. Where has my head been. Takes you Andy to explain it all.
ReplyDeleteYikes! I'm glad they are trying to control that blood sucker!
ReplyDeleteI wouldn't think that a simple fence would be sufficient to keep these pests out, but, if it works, I am happy.
