Below is a list of fly fishing manners borrowed from flyanglersonline.com and I believe written by Deanna Birkholm. Are there more that should be added to the list? Are there some ethics that could be added regarding the fish themselves? Such as targeting smolt or fishing when water conditions are not favorable to the fish i.e. warm temps, low water conditions etc. 1. A section of water belongs to the first person fishing it. It is inconsiderate to crowd an angler who was there first. 2. A slow moving or stationary angler has the right to remain where he/she is. If you are moving, leave the water and quietly walk around the angler in position in the water. 3. If an angler is resting the water, (Allowing the water to calm down after some form of disturbance. Generally, after a fish has been caught, the act of the fight scares the rest of the fish and makes them hesitant to hit on a fly, so you Rest the Water until it is fishable again.) or planning his/her next move, it is his/her water. Don't jump in without permission. 4. A person working upstream has the right of way over someone fishing downstream. 5. Always yield to an angler with a fish on the line. 6. Do not enter the water directly in front of someone already in the water. 7. Always recognize property rights. Leave all gates as you found them. 8. Do not litter. If you brought it in, take it out. Leave the area cleaner than you found it. 9. Try not to make tracks whenever possible. 10. Wade only when necessary. The aquatic food chain is fragile. 11. Obey all state and local fishing laws and rules.
