Fishing in is something that players learn about almost immediately upon beginning the game, but the selection of fish available varies by location, including on Eternity Isle. Therefore, while there are plenty of species of fish to capture in the main valley, Eternity Isle specifically adds 15 new ones to the list.
There are three new biomes on Eternity Isle: Ancient's Landing, Glittering Dunes, and the Wild Tangle. Each area has seafood specific to its biome, meaning that these creatures cannot be caught elsewhere. Luckily, fishing on Eternity Isle works the same as it does on the mainland, so tracking them all down should be simple once you know where to look.
Ancient's Landing is the first biome players will encounter upon reaching Eternity Isle. There will be four new species to fish for in this biome, including the Octopus, Robot Fish, Sea Snail, and Shad. These are completely new as part of the expansion. However, some of the mainland fish can also be found here as well so don't be surprised if you hook one.
Specifically, Cod and Sole Fish from the mainland can be caught in Ancient's Landing. Additionally, though Ancient's Landing has four sub-regions, only two will contain all of these fish and those are The Docks and The Overlook.
