Forsaken Shores

Forsaken Shores has a pirate flavor that shows up in its fish names: Corsair Grouper, Galleon Goliath, Buccaneer Barracuda, Cutlass Fish, Scurvy Sailfish and Cursed Eel are all tied to it. Residents include a Shipwright, Cort, a Beach Keeper and Jack Marrow, and both a crab cage and a bait crate are available.

The wiki documents 13 fish here: 2 each of Limited, Mythical, Uncommon, Common and Unusual, plus one each of Secret, Rare and Legendary. The spread is even enough that a session will feel varied without one rarity dominating.

The headline is the Pirate Captain's Goldfish, a Secret averaging C$22,570. Following it are Golden Seahorse (Mythical, C$2,537.50), Captain's Goldfish (Mythical, C$1,632), Ancient Serpent Skull (Limited, C$900) and Shipwreck Barracuda (Legendary, C$680). That gap between first and second is large, which tells you that one Secret catch is worth far more than a whole session of ordinary fish.

On the shopping side you will find Scurvy Rod (C$50,000) and the Great Rod Of Oscar, listed at 2,500,000$.

This is a good stop if you are aiming for a single big payout and want facilities close at hand. If you only want steady income, a shallower pool with more consistent averages might suit you better.
