Amoskeag Fishways - Sea Lamprey Appreciation Day

I attended the Sea Lamprey Appreciation Day at the Amoskeag Fishways in Manchester, NH. It offers the opportunity to handle this fascinating primitive fish. In the video you'll see children wearing gloves, these are being worn to protect the slime on the fish. I was able to feel the suction when I placed my fingers near the mouth parts.

Young lampreys are filter feeders and have no means of digesting blood

Impressive looking machine which I guess is used to capture a bucket of fish for stocking streams

Topological Sandbox was a big hit
