Top 10 Best Food Sources in Subnautica 2 Ranked by Nutrition

How Food Works in Subnautica 2

Hunger and water are the two survival stats you must manage in Subnautica 2. Different foods restore different amounts of each, and some foods also have side effects like reducing water or spoiling over time. The best food sources maximize hunger restoration, provide water alongside it, and can be farmed for a permanent supply. This list ranks the 10 best by overall nutritional value.

Ranks 10 to 8

10. Cooked Boomerang

Basic early-game food from the safe shallows. Restores a small amount of hunger and a tiny bit of water. Easy to catch but low value; replace it as soon as possible.

9. Cooked Peeper

Better than Boomerang with moderate hunger and small water restoration. Peepers are everywhere and easy to farm, making them a reliable staple in the early game.

8. Cured Peeper

Cured Peepers restore the same hunger as cooked but never spoil, making them the best travel food early on. The trade-off is reduced water, so pair them with a water source.

Ranks 7 to 5

7. Cooked Spadefish

Found in the grassy plateaus. Solid hunger and moderate water restoration. A good mid-game fish that is easy to catch in bulk.

6. Cooked Holefish

Cave-dwelling fish with higher hunger value than most common species. Worth seeking out for the nutrition boost on longer dives.

5. Bulbo Tree Sample

A farmable plant that restores both hunger and water when eaten raw. Bulbo trees can be grown in exterior growbeds and harvested repeatedly, giving a self-sustaining food and water supply without cooking.

Ranks 4 to 2

4. Marblemelon

The classic farmable food. Each Marblemelon restores a good chunk of hunger and water, and you can grow them in interior plant pots or growbeds. Slice a Marblemelon into seeds to replant, creating an infinite food loop. This is the most popular base food source.

3. Cooked Reginald

The single best cooked fish for hunger restoration. Reginalds are large, meaty fish that you can farm in alien containment for an endless supply. High hunger, decent water, and renewable.

2. Cured Reginald

Cured Reginalds combine the highest hunger value with zero spoilage, making them the ultimate travel and expedition food. Stockpile them in your Cyclops and Prawn Suit for deep-sea runs. The only downside is reduced water, so carry Large Filtered Water alongside them.

1. Marblemelon Farm - The Best Overall Food System

1. Marblemelon Farm

The Marblemelon farm is the best food source in Subnautica 2 because it is self-sustaining, restores both hunger and water, requires no fuel or fishing, and fits in a small growbed. Plant four Marblemelons, eat three, and slice the fourth for seeds to replant. You will never run out of food or water again. Combined with Cured Reginalds for travel, this system covers all your survival needs.
