How do I complete the "A Fisher of Fish" mission in Red Dead Redemption 2?

The ''A Fisher of Fish'' mission in Red Dead Redemption 2 is a unique side quest that involves catching legendary fish across the game world. To start this mission, you must first meet Jeremy Gill, a fisherman who resides at Gill Landing, located northeast of Flat Iron Lake. He will provide you with a map and a list of 13 legendary fish to catch. This mission is available after completing Chapter 2 and unlocking fishing mechanics.\n\nBefore you begin, ensure you have the appropriate fishing gear. You will need a fishing rod, which is obtained during the ''A Fisher of Men'' mission with Jack Marston, and special lures. Jeremy Gill will give you the Special Lake Lure, but you will also need the Special River Lure and Special Swamp Lure. These can be purchased from the bait shop in Lagras, located in the Bayou Nwa region. Without these lures, you cannot catch legendary fish.\n\nEach legendary fish is found in a specific location, and the map provided by Jeremy Gill will guide you to these spots. For example, the Legendary Smallmouth Bass is found in O''Creagh''s Run, a lake in the Grizzlies East region. To catch it, equip the Special Lake Lure and cast your line into the water. Legendary fish are more challenging to catch than regular fish, so be prepared for a fight. Use the reeling mechanic by holding the right stick down to pull the fish closer and then quickly flicking it up to reel in the line.\n\nOne common challenge is locating the exact fishing spot for each legendary fish. The map markers are general, so you may need to explore the area to find the ideal spot. For instance, the Legendary Longnose Gar is found in the swampy waters of Lagras, but you may need to move around to find the exact spot where the fish bites. Patience is key, as legendary fish may take some time to appear.\n\nAnother challenge is managing your stamina during the fishing process. Reeling in a legendary fish can drain your stamina quickly, so make sure to use the reeling technique efficiently. If your stamina runs out, the fish may escape. To avoid this, pause occasionally to let your stamina recover before continuing to reel.\n\nOnce you catch all 13 legendary fish, return to Jeremy Gill at Gill Landing. He will reward you with a unique item and complete the mission. Keep in mind that some legendary fish are only available in specific weather conditions or times of day, so plan your fishing trips accordingly.\n\nPractical tips for this mission include saving your game before attempting to catch each fish. If you fail or lose the fish, you can reload your save and try again. Additionally, use Eagle Eye to spot fish in the water, as it highlights their locations. Finally, consider upgrading your fishing rod and lures to improve your chances of success.\n\nIn summary, the ''A Fisher of Fish'' mission requires preparation, patience, and skill. By following the map, using the correct lures, and mastering the fishing mechanics, you can successfully complete this challenging and rewarding quest.
