This technical guidance factsheet was developed as part of a series of practical on-farm hatchery management guides based on the FAO Artemia Manual. It provides a concise, user-friendly reference for hatchery operators on the cold storage of Artemia nauplii to maintain their nutritional quality for short-term use. The factsheet outlines key requirements for successful storage, including nauplius stage selection, stocking density, temperature control, aeration and oxygen management, and maximum storage duration. It also highlights critical monitoring points to help maintain nauplii quality and viability while ensuring a reliable supply of live feed for hatchery operations. Presented in a highly visual format, the guide transforms the detailed information contained in the FAO Artemia Manual into a practical tool that supports the safe and effective production of high-quality Artemia for aquaculture hatcheries.
