Catch & Release Tool

As fly fishers, we understand the importance of being good stewards for both the environment and the fish we love, but unfortunately our usual practice of landing a fish in a net and holding it while we remove the fly can be very harmful to the fish. As described in the catch and release study you can download below, fish evolved to live and function in water and, once removed, their gills collapse and their respiratory system shuts down, which is especially dangerous when the fish is stressed and exhausted after a fight. Furthermore, touching a fish, especially with dry hands or gloves, can remove the protective slime a fish needs to protect itself from bacteria. Clearly, the best practice is to touch the fish as little as possible and return it to the water as quickly as possible.

In a dedicated effort to do less harm, an HCFF member developed the Catch & Release Tool (CRT) in early 2020. Several members then tested the tool extensively during the year and discovered they could easily release fish without using a net or ever touching the fish except for an occasional photograph. High Country Fly Fishers then created 250 CRTs for distribution to local fly fishers.

Instructions for Use

If you are right-handed, once the fish is close, use your left hand to grab the leader about a fish-length above the fish. Hook the leader with the CRT in your right hand, slide the tool down to the fish’s mouth and connect the CRT hook to the bend of the fishhook. Once you have the two hooks connected, move the leader to the fish’s tail with your left hand. You should then be holding the fish vertically by the CRT. The weight of the fish is usually enough for the hook to release from the fish’s mouth and drop it safely into the water. If not, a little shake will do the trick. With a barbless hook, the release is even quicker.

Fabrication Hints

For the HCFF project, we set out to make 250 CRTs and one of our team had a wood shop with a wide variety of tools. We used a miter saw to cut the dowels and set up a fence on so we could cut four dowels at one time. Then we used a drill press with a jug to hold the dowels vertical and drill the holes. Finally, we used a belt sander to round the ends.
