What are you fishing for here?Advice
Pick from the species named in Au Sable River's rules. Setups are checked against the gear rules in force today, and your picks are remembered on this device only. These are rule-aware suggestions, not a claim about what is biting; advice, not law, and the rules above govern.
You also need (Michigan)
- No trout stamp or species endorsement. Michigan does not sell a trout stamp or any species-specific add-on. Every Michigan fishing license is an all-species license covering all species allowed for harvest.
- Must carry license AND your purchase ID. You must have both the license and the ID you used to buy it on you while fishing, and show both if a conservation officer or any law enforcement officer asks.
