Simply get a few feet of outdoor carpet - the plastic, artificial turf they sell at the big hardware stores. The carpet works great - just like velcro, to hold the big fish in place as we fillet them.
We keep a few feet folded up in the boat for when we are camping...

A few dollars of carpet will last for years. The green is easy to see if you get a fleck on the meat, and makes the meat look perty...

This piece is 4 years old, and going strong.

Good as new, and ready to get used again!
