The document discusses the role of microalgae as food in aquaculture, particularly for fish and crustaceans, and outlines challenges faced by hatcheries due to culture collapses. It proposes the development of an alternative microalgae feed paste that is economical, eco-friendly, and can be used to start new cultures, with field tests showing promising survival rates for fish. The algal paste is positioned as a cost-effective substitute for live microalgae and has garnered positive feedback from hatchery operators.
Juan Algae Paste
- 2. Role of Microalgae in Aquaculture • Primary producers in aquatic ecosystem • Natural food for early stages of fish larvae (i.e. milkfish, tilapia) and early stages of crustaceans (i.e. shrimp and mangrove crab)
- 3. CULTURE CRASH Difficulty & Challenges Faced by Hatcheries
- 4. •Sourcing out of green water from other hatcheries •Procurement of algal inoculum to start another culture •Procurement of imported commercially available microalgal paste as feed Immediate solutions in Hatcheries when culture collapses?
- 5. Our Proposed Solution ! Come up with an alternative microalgae feed form that : Ensure steady supply of microalgae as basic feed for zooplankton (i.e rotifer) and as direct feed for shrimp larvae. Can be used as an inoculum to start another batch culture
- 7. Why Algae Paste? Convenient to use Readily available, locally produced Economical Live microalgae All natural, no preservative added Eco-friendly

- 15. Current Status UPV Algal Paste Protocol already established utilizing the Algal concentrator (AlgaCon) which can harvest 2-3 kgs m-3 paste culture volume Algal paste is working, acceptable and performs similarly with the cultured live microalgae Algal paste can be an alternative feed to live culture AP can be used to start a new batch culture, which is particularly important when difficulty in culture is encountered
