To get the sea fishing rod in Persona 4 Golden, first catch the River Guardian. Complete Quest 60 at Samegawa Flood Plain. Then, trade a Ladybug at Tatsuhime Shrine for a fishing hook. Finally, give the fishing hook to the Old Man at the riverbank to receive the Deep-Sea Rod for fishing at Shichiri Beach.
Next, you must acquire the Sea Fishing Rod itself. Head to the shopping district during the summer months. In the district, find the shop that sells fishing gear. Purchase the Sea Fishing Rod for 8,000 yen. Being equipped with this rod enhances your fishing experience. It allows you to catch larger fish in the ocean compared to basic rods.
Equipped with the Sea Fishing Rod, players can now explore various fishing locations. They can try for rare fish and larger catches that contribute to their fishing achievements. These experiences open avenues for crafting and completing quests later on. Understanding fishing will enrich your overall gameplay and lead to valuable rewards.
