I had to do some KHV testing on some of our new arrivals over the weekend. This is part of the setup. We knock out the koi and lay them up here while we draw the blood.
The koi are labeled and photographed to keep track of their blood samples. This koi is about to get knocked out.

The finished product ready to be filled minus the puppy.
