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.

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 enrichment of Artemia nauplii to enhance their nutritional value before feeding to fish and shrimp larvae. The factsheet outlines the key steps involved in nauplii enrichment, including tank preparation, enrichment product preparation and application, harvesting of enriched nauplii, and storage options. It also highlights critical operational parameters, such as nauplii density, dissolved oxygen, temperature and pH, to support effective enrichment and the production of high-quality 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.

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 harvesting of Artemia nauplii and their effective separation from unhatched cysts and empty shells. The factsheet describes key procedures for harvest preparation, nauplii collection using concentrator-rinser or sieve-based methods, and subsequent handling options, including direct feeding, short-term storage or enrichment. It also highlights critical operational considerations to maximize nauplii quality and purity while minimizing the risk of larval mortality associated with the presence of cyst shells. 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.

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 hatching of Artemia cysts to obtain high-quality instar I nauplii. The factsheet summarizes the key operational parameters affecting hatching success, including cyst density, aeration, salinity, temperature, pH, illumination and incubation duration. It also highlights the materials required, recommended operating ranges and critical monitoring points to help ensure optimal hatching performance and consistent nauplii production under hatchery conditions. 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.

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.
