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 decapsulation of Artemia cysts, a process that removes the outer shell to improve hatching efficiency, reduce contamination risks and allow the direct use of decapsulated cysts as feed. The document describes the complete procedure, from cyst hydration and chemical decapsulation to monitoring, washing, chlorine neutralization and storage. It also highlights essential safety measures, including the handling of hazardous chemicals, temperature control and proper effluent management. 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.
