Fishing is one of many activities in Red Dead Redemption 2. One of the Trophies as well as one of Stranger Missions requires You to catch 14 legendary fishes and mail them to Jeremy Gill. Here we will try to help You catch them and complete the quest.
How to Catch Legendary Fish
First of all you will need to get three special baits from the Bait Shop in Bayou Nwa near Lagras Lake. Once you get there, purchase Special Lake Lure, Special River Lure and Special Swamp Lure from the shop, each costs $20. In fact, any special lure can be used anywhere to catch a legendary fish, but used the right lure will make it a lot easier. Bait is not needed, so do not select any bait to catch them.
Legendary fish will always struggle a lot and you reel may run out of line, so the best way to stop it and catch the fish is to pull your fishing rod up and reel in very slowly. But don't forget to let it rest for a second or two every now and then or your line may snap.
