that silvers a jumper anyway look at the drop scales down both sides even when vid starts, and how they both talk about it in the vid, thats not the first time its hit the floor im willing to bet... any koi shop should have massive bags in stock... thats where i get mine from... you can either use a a large net handle, strong wire or a modified coat hanger to hold the bag open and allow you to move it and coerce the fish in... basically take a large bag, drop it thru the circle of wire then roll the ends around the wire so its open like a net, you can use clips to secure it until the fish is inside! then i suggest with a aro of that size you will want to place the bag in another bag and then into a poly box with a lid on the darken it...
