Terrapin Island

Terrapin Island is a mostly deserted, turtle-shaped island in the First Sea, where very few NPCs fish around the shores. It is obtainable, has a bait crate but no crab cage, and lists three residents: an Angler, a Shipwright and Jack.

Eleven fish are documented across seven rarities, a spread that makes it a decent place to learn what each tier pays. The top is Sea Turtle, Mythical, at about C$1,465, then Manatee (Secret) at C$1,250, Olm (Legendary) at C$675, Golden Smallmouth Bass (Legendary) at C$625 and Chinook Salmon (Unusual) at about C$148.2. Note that the Secret fish here pays less than the Mythical one, so rarity labels do not always match price.

Two rods are sold on the island: the Magnet Rod at C$15,000 and the Wildflower Rod at C$40,000, both within reach of a player still building a budget.

My advice: this is a mid-tier stop that suits newer players. The bait crate and the cheap rods help you build up, and the top fish are worth enough to feel like progress without needing a late-game setup.
