Koi Sock Nets
http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=12291
Custom designed to protect the long delicate fins of Butterfly Koi and ornamental Goldfish during selective catch and release. Simply grip the tapered end to close, gently dip and scoop to capture, then open your hand to safely pass your koi though the other end when done. One-way passage prevents damage to fins, scales, or slime coat. Silky-soft netting and padded frame ensures abrasion-free capture, while the wide wooden handle gives you precise control. For quick transfers, breathable
Fine Mesh net lets water drain out. The
Ultra-fine Mesh net has a much tighter weave and will not pass water quickly to keep koi suspended for longer observation, dosing, and transport. 12" Handle x 12" Net x 40" Depth.
