Stainless Steel Stringer

 

This is one handy stringer, comes with me on every trip .  I've made several for different people and they use it on the big ones they don't want to get away. 

Just push the rod through the gills, out the mouth and through the brass ring.  I usually leave the link finger-tight, so I can remove the cable from the rod to release the fish easier.

You can also use a wooden dowel for the rod.
