Where can I find all legendary fish to unlock the "Fisher of Fish" achievement?

To unlock the ''Fisher of Fish'' achievement in Red Dead Redemption 2, you must catch all 13 legendary fish scattered across the game world. This task requires patience, preparation, and knowledge of specific locations and mechanics. Legendary fish are unique, and each can only be caught once. You’ll need the Special Lake, River, and Swamp Lures, which can be purchased from the bait shop in Lagras, near the Kamassa River. These lures are essential, as regular bait won’t work on legendary fish.\n\nBefore starting, ensure you have the right equipment. You’ll need a fishing rod, which is unlocked during the mission ''A Fisher of Fish'' in Chapter 2. This mission introduces you to Jeremy Gill, the NPC who tracks your progress. After completing the mission, you’ll receive a map showing the general locations of the legendary fish. However, the map is vague, so you’ll need to explore specific spots to find them.\n\nEach legendary fish is tied to a specific body of water, and they only appear under certain conditions. For example, the Legendary Bluegill is found in Lake Don Julio, while the Legendary Smallmouth Bass is in O’Creagh’s Run. Weather and time of day can also affect their appearance, so if a fish isn’t biting, try returning at a different time or during different weather conditions. Save your game before attempting to catch a fish, as this allows you to reload if something goes wrong.\n\nWhen fishing for legendary fish, use the Special Lures and cast your line into the water. Legendary fish are much harder to catch than regular fish, so be prepared for a struggle. Reel in slowly and steadily, and avoid jerking the rod too hard, as this can cause the line to break. If the fish starts thrashing, release the tension slightly to avoid snapping the line. Once caught, you can either keep the fish or mail it to Jeremy Gill using the post office.\n\nSome legendary fish are harder to find due to their remote locations. For example, the Legendary Bullhead Catfish is in the far north of the map, near Willard’s Rest. This area is difficult to access, so make sure your horse is well-stocked with supplies. Similarly, the Legendary Perch is in Lake Isabella, a cold and mountainous region. Dress warmly and bring health tonics to survive the harsh environment.\n\nA common challenge is the Legendary Salmon, found in the Dakota River near Cumberland Falls. This fish is particularly elusive, and players often struggle to locate it. To increase your chances, stand on the rocks near the waterfall and cast your line into the deeper parts of the river. If the fish doesn’t bite after several attempts, try leaving the area and returning later.\n\nOnce you’ve caught all 13 legendary fish and mailed them to Jeremy Gill, he will invite you to meet him at his cabin. This final interaction completes the questline and unlocks the ''Fisher of Fish'' achievement. Remember to save your progress frequently, as losing a legendary fish can be frustrating and time-consuming to rectify.\n\nPractical tips for success include upgrading your fishing rod with better reels and lines, which can be purchased from general stores. Additionally, use Eagle Eye to spot fish in the water, as this ability highlights their locations. Finally, be patient and persistent, as some fish may take multiple attempts to catch. With the right preparation and strategy, you’ll soon add this achievement to your collection.
