The RUST Sardine is one of many types of fish that can be caught via the fishing system and can be consumed for health or used in composting. Facepunch added Fishing as an in-game activity during the Going Deep patch in August of 2021.
In addition to the fishing quest, new fish types are useful in farming when deposited into a Composter or can be gutted directly for raw resources (an excellent source of Low Grade Fuel). Some fish can be turned in directly at Fishing Villages for Scrap while others are better used when fishing to achieve a higher Bait Rating.
Sardines can be caught in all water types regardless of depth and require a bait level of 0.5 – 2.5 to catch.
