Subnautica's Survival Mode requires you to maintain your health by eating food and drinking water. The best way to do this is by finding edible fish, which can be cooked and cured to your liking. There are 14 different varieties to choose from, and some are more nutritious than others.

They can be found in several different biomes, and it is important to know which ones to look out for when you are far away from your base. It only takes about 50 minutes for you to starve to death in Subnautica, so make sure to always have a supply of fish on hand to prevent this tragedy.
