Food is the second pillar of survival alongside water in Subnautica 2. Your hunger meter depletes over time, and if it hits zero you start taking steady health damage. Unlike water, you have a bit more time before starvation becomes critical, but ignoring hunger will eventually kill you. Managing food efficiently lets you focus on exploration rather than constant foraging.
Here is how the food system works:
- Raw fish: Caught by hand or with tools. Restores some food but can carry infection risk and provides less nutrition than cooked.
- Cooked fish: Process raw fish at a Fabricator. Cooked food restores more hunger and is safer to eat.
- Cured fish: Combine raw fish with salt at a Fabricator. Cured food lasts much longer without spoiling, making it ideal for expeditions.
- Food spoils: Raw and cooked food decays over time. Spoiled food provides little nutrition and can make you sick.
- Cured food does not spoil: This is why curing is the best method for long trips.
The key to food management is balancing immediate nutrition with long-term storage. Cooked fish is best for eating right away, while cured fish is best for stocking up before a deep expedition. Always keep a mix of both so you are never caught without a meal.
Note that some foods also restore a small amount of water, making them doubly valuable. Prioritize these dual-benefit foods when available.

Best Food Sources and Where to Find Them
Different fish species provide different food values. Knowing which fish to target saves time and keeps your hunger bar full with less effort. Here are the best food sources in Subnautica 2:
| Fish | Food Value | Where Found | Notes |
|---|---|---|---|
| Peepers | High | Shallow and mid-depth biomes | Best common food fish, also restores water |
| Bladderfish | Low-Medium | Shallow waters | Also used for water; dual purpose |
| Reginalds | Very High | Mid-depth biomes | Top-tier food value per fish |
| Holefish | Medium | Cave and crevice biomes | Found in tight spaces |
| Garryfish | Medium | Shallow grassy zones | Easy to catch early |
| Spadefish | Medium-High | Underwater island zones | Good mid-game option |
The Peepers are your bread and butter. They are common, easy to catch, provide solid food value, and also restore a bit of water -- making them the most efficient early-game food source. Hunt them in shallow and mid-depth waters.
The Reginald is the premium food fish. It provides the highest food value per catch, meaning you need fewer fish to stay full. Prioritize Reginalds once you can safely reach their mid-depth habitats.
Catch fish efficiently by swimming slowly toward them and grabbing them before they flee. A Seaglide helps you close distance quickly. Some fish are skittish and require patience, while others like the slow-moving Bladderfish are trivial to catch by hand.
Cooking Recipes and Food Storage Tips
Processing your catch at a Fabricator dramatically improves its value. Here is how to get the most from your food through cooking and curing:
Cooking at the Fabricator converts raw fish into cooked food, which restores significantly more hunger than raw and is safer to eat. Always cook your fish unless you are curing them for storage. Cooking is instant at a Fabricator, so process your catch as soon as you return to base.
Curing combines raw fish with Salt Deposits at the Fabricator to create cured food that does not spoil. Cured food is slightly less nutritious than freshly cooked food, but its infinite shelf life makes it the best choice for long expeditions. Here is when to use each method:
- Cook and eat now: When you are hungry and at base. Cooked food gives maximum nutrition.
- Cure and store: When preparing for a trip. Cured food lasts forever and is perfect for deep dives and long explorations.
- Keep salt on hand: Always collect Salt Deposits when you see them so you can cure fish on demand.
Food storage and efficiency tips:
- Build storage lockers for food: Keep cooked and cured fish organized in labeled lockers so you always know your supply.
- Check food before expeditions: Always leave base with a full hunger bar and at least 2-3 cured food items.
- Eat before you are starving: Top off hunger proactively rather than reacting to low levels.
- Discard spoiled food: Spoiled food provides almost no nutrition and can be harmful. Throw it away.
- In co-op, share the load: One player manages food supply for the group, curing and stocking a shared locker.
- Use indoor growbeds: Some plants are edible and renewable. A growbed with edible flora provides a steady food source without fishing.
With a combination of cooked food for immediate use, cured food for expeditions, and an indoor growbed for renewable backup, you will never struggle with hunger again. Food management becomes a solved problem, freeing you to focus on exploration and progression.
