  2. Background • Alveolar layer of the cyst are removed Live food aquaculture training course www.aquatrain.org

  3. Why decapsulated cysts? • A complete contamination free and sterile product • Separation problems after hatch are avoided Live food aquaculture training course www.aquatrain.org

  4. Preparation Addition of water and strong aeration Tank set-up with stainless steel filter and aeration system Live food aquaculture training course www.aquatrain.org

  5. Hydration Dry cysts are hydrated in water with strong aeration Live food aquaculture training course www.aquatrain.org

  6. Addition of chlorine and caustic soda => increases pH above 10 • Addition of chlorine and hypoclorite solution • Temperature should be maintained within 25-30C Live food aquaculture training course www.aquatrain.org

  7. Colour change Process lasts from 5-15 min • Dark brown • Grey • Orange The process is stopped immediately after orange colour appear Live food aquaculture training course www.aquatrain.org

  8. Checking of bouyancy • Decapsulated cysts will sink • Non-decapsulated cysts will float Live food aquaculture training course www.aquatrain.org

  9. Termination of process • Process is stopped by adding large amounts of water until the smell of chlorine has disappeared • Hypoclorite residue absorbed by the cysts is neutralized by • 0.1 % Sodium Thio-sulfate Live food aquaculture training course www.aquatrain.org
