How do I complete the "Fisher of Fish" side quest in RDR2?

The ''Fisher of Fish'' side quest in Red Dead Redemption 2 is a multi-part fishing challenge that requires you to catch 13 legendary fish across the game''s vast map. To start the quest, you must first meet Jeremy Gill, a fisherman who resides at Gill Landing, located northeast of Flat Iron Lake. You can find him after completing Chapter 2 and unlocking the fishing mechanics by helping Jack Marston catch a fish during the ''A Fisher of Men'' mission.\n\nOnce you meet Jeremy, he will give you a map marking the locations of all 13 legendary fish. Each fish is unique and can only be caught in specific bodies of water. To catch these fish, you will need the Special Lure, which can be purchased from the bait shop in Lagras, located in the Bayou Nwa region. The Special Lure is essential because legendary fish will not bite regular bait.\n\nBefore heading out, ensure you have the right equipment. You will need a fishing rod, which is unlocked during the ''A Fisher of Men'' mission, and the Special Lure. Additionally, stock up on health tonics and stamina tonics, as catching legendary fish can be physically demanding. Some fish are located in remote or dangerous areas, so prepare for potential encounters with wildlife or hostile NPCs.\n\nEach legendary fish has specific conditions for catching it. For example, the Legendary Smallmouth Bass can be found in O''Creagh''s Run, a lake in the Grizzlies East region. To catch it, cast your line into the deeper parts of the lake and use the Special Lake Lure. Pay attention to the fish''s behavior; legendary fish are more aggressive and will fight harder than regular fish. Use the reeling mechanics effectively by holding the right stick down to tire the fish and then reeling in when it stops struggling.\n\nOne common challenge is locating the exact spots where the fish spawn. Use the map provided by Jeremy Gill as a guide, but also look for visual cues in the environment, such as ripples or splashes in the water. If you''re having trouble, consider using Eagle Eye to highlight the fish''s location. Additionally, some fish are only available during specific weather conditions or times of day, so be patient and return if necessary.\n\nAfter catching all 13 legendary fish, return to Jeremy Gill at Gill Landing. He will reward you with a unique item and complete the quest. This quest is a great way to explore the game''s world and enjoy its immersive fishing mechanics. It also provides a sense of accomplishment and a deeper connection to the game''s environment.\n\nPractical tips for completing the ''Fisher of Fish'' quest include saving your game before attempting to catch each fish, as legendary fish can be tricky and may require multiple attempts. Also, consider upgrading your stamina and health cores to make the fishing process easier. Finally, take your time and enjoy the journey; the quest is designed to be a relaxing and rewarding experience.
