Presentation transcript:

Live food aquaculture training course Demonstration of Artemia decapsulation

Live food aquaculture training course Background Alveolar layer of the cyst are removed

Live food aquaculture training course Why decapsulated cysts? A complete contamination free and sterile product Separation problems after hatch are avoided

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

Live food aquaculture training course Hydration Dry cysts are hydrated in water with strong aeration

Live food aquaculture training course Addition of chlorine and caustic soda => increases pH above 10 Addition of chlorine and hypoclorite solution Temperature should be maintained within  C

Live food aquaculture training course Colour change 1.Dark brown 2.Grey 3.Orange The process is stopped immediately after orange colour appear Process lasts from 5-15 min

Live food aquaculture training course Checking of bouyancy Decapsulated cysts will sink Non-decapsulated cysts will float

Live food aquaculture training course 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 Transfer to hatching tank
