Where can I find all legendary fish for 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, larger-than-normal fish that can only be caught once per playthrough. Each has a specific habitat, and you''ll need the right bait and equipment to succeed.\n\nFirst, you must unlock the Legendary Fish questline. This begins in Chapter 2 when you meet Jeremy Gill, a fisherman who sends you a letter inviting you to his cabin at Flat Iron Lake. His cabin is located on the southeastern shore, near the ''L'' in ''Flat Iron Lake'' on the map. After meeting him, he will provide you with a map showing the general locations of all 13 legendary fish. This map is essential for tracking your progress.\n\nTo catch legendary fish, you''ll need special lures. These can be purchased from the bait shop in Lagras, a small village in the Bayou Nwa region of Lemoyne. The shopkeeper sells three types of special lures: the Special Lake Lure, Special River Lure, and Special Swamp Lure. Each lure is designed for specific water types, so make sure to equip the correct one based on the fish''s habitat. For example, the Legendary Smallmouth Bass is found in O''Creagh''s Run, a lake, so you''ll need the Special Lake Lure.\n\nEach legendary fish has a unique spawn location. For instance, the Legendary Longnose Gar is found in Stillwater Creek, a swampy area in Lemoyne. The Legendary Muskie is located in Lake Isabella, a frozen lake in the Grizzlies West region. Use your map to pinpoint these locations, and look for ripples or splashes in the water to identify where the fish is active. Once you spot the fish, cast your line near it and wait for a bite.\n\nCatching legendary fish can be challenging due to their size and strength. When a fish bites, hold down the reel button (R2/RT) to hook it, then alternate between reeling in and lowering your rod to tire it out. Be patient and avoid reeling too quickly, as this can cause the line to break. If the fish starts thrashing, stop reeling and let it tire itself out before continuing. This process can take several minutes, so stay focused.\n\nAfter catching all 13 legendary fish, return to Jeremy Gill at his cabin. He will reward you with a unique item and the ''Fisher of Fish'' achievement. Keep in mind that some legendary fish are only accessible in specific chapters or after completing certain missions. For example, the Legendary Perch in Lake Owanjila is easier to access after completing the ''A Fisher of Fish'' mission in Chapter 6.\n\nPractical tips for success: Always save your game before attempting to catch a legendary fish, as they can be tricky to hook. Use Eagle Eye to spot fish more easily, and make sure your fishing rod is equipped with the correct lure. If you''re struggling to find a fish, try visiting its location during different times of day or in different weather conditions. Lastly, be prepared for long fishing sessions, as some legendary fish require significant effort to catch.\n\nBy following these steps and tips, you''ll be well on your way to unlocking the ''Fisher of Fish'' achievement and mastering the art of fishing in Red Dead Redemption 2.
