Tuna

Basic Fishing area

Yellowfin tuna is a solid resource, but keep smaller stocks of it than of herring, because you will only use it in two recipes.

What it's for

Although great in a salad, tuna fish are surprisingly sleek, streamlined and efficient predators. Not only that, but they are the only species of fish that can maintain a body temperature higher than that of the surrounding water.

Yellowfin tuna is the second cheapest fish from the Fishing area with a base price of 27 000 dollars, right behind herring. It is caught the same way as the other basic fish, so only in fishing boats, the shop does not sell it. In the game it is described as a fast predator that keeps its body temperature higher than the surrounding water, but on the farm it serves purely as a resource for The Mermaid Bay kitchen. Its production recipes are exactly the same as herring's, they differ only in price and in where you process it next.

How to get it

The recipes for tuna are absolutely identical to herring's, so here too the best units per hour ratio comes from the Norfolk punt at the highest level, 161 units in just under 16 hours from a single corn. The Motorboat is only worth it for topping up smaller amounts when you do not have the punt free.

What to do with it

Tuna goes to The Mermaid Bay for Fried fish treats and Canned fish, and you can also send it to the Dockyard. Unlike herring it is not used by the Fish market, so it has a narrower use in just two main recipes.

Tip from a veteran player Because tuna has only two recipes in The Mermaid Bay, keep an eye on the consumption of both and do not catch more of it than the recipes actually use up, otherwise the surplus just sits in storage.

Most common mistake People often mix tuna up with herring because of the identical production times, so they catch only one kind and then miss the other in storage when they want to finish a recipe in The Mermaid Bay.
