Japan Mud Pond Harvest 2010

Here's a of a Koi breeder grading his Koi that he grew over the summer in a mud pond somewhere around the Yamakoshi area in Niigata, Japan.

After harvesting the Koi, the breeder brought the Koi back to a greenhouse, where he grades each Koi individually in a Koi measuring tub. It looks like he is grading 3 year old Gosanke.
