Appendix II. Decapsulation Procedure for. Artemia Cysts. Hydration. 1. Hydrate cysts by placing them for 1h in water (less than g l 1), with aeration, at 25°C. In order to ensure the highest nutritional value, Artemia cysts should be decapsulated prior to hatching. This will disinfect the cysts, remove the. The present paper describes the technology developed by the authors for the routine decapsulation of Artemia cysts. The advantages which.

Dimpled or Dehydrated Brine Shrimp. Then put the eggs in a solution of sodium thiosulphate Na 2 S 2 O 3. Artemia eggs which have been decapsulated have a higher hatching efficiency than those which are not decapsulated. Brine shrimp eggs which have been decapsulated are in a better condition for hatching than those which are not decapsulated Table 1.

Hyperlinks to non-FAO Internet sites do not imply any official endorsement of or responsibility artemoa the opinions, ideas, data or products presented at these locations, or guarantee the validity of the information provided. Comparisons of hatching efficiency between non-decapsulated eggs and those decapsulated either with sodium hypochlorite or calcium hypochlorite bleaching powder show the decapsulated artemia eggs to have better hatchability.


We fill it to only ml versus ml 1 liter so there is more room in the cone. Aeration of both water and eggs must be continuous to re-hydrate the eggs fully. The salt will dehydrate the eggs.


Once the orange color is reached the reaction must be neutralized. The Chacheongsao Fisheries Station, which is responsible for this project experiment, carries out research, training and technological development in the field of fresh and brackishwater prawn farming.

Stir until mixed thoroughly.

Cecapsulation artemia is a very tiny animal which has no shell. The result of this experiment proved that chemical substances that are cheaper and more readily available in the Thai market, such as lime CaO and bleaching powder calcium hypochloritecan be used as stimulating agentsin the decapsulation of artemia eggs.

Proceedings of the World Mariculture Society, 9: To store the decapsulated brine shrimp make a saturated salt solution using a pop bottle. Add a small amount of water. Non-hatching artemia, however, is also a great feed for aquarium and hatchery users alike. Leave the decspsulation eggs at this stage for 45—60 minutes.

To begin the process of decapsulation, the artemia cysts brine shrimp eggs need to be hydrated. Wash the eggs in the filter bag with water once more. This may take minutes depending on the egg hatch-out, harvest year, etc and sodium hypochlorite solution…however it is more important to watch the coloration than the minutes.

The size of the egg is approximately — microns. Artemia eggs can be preserved in this manner for a long time. Decapsulated eggs preserved in refined salt for more than 7 weeks retained normal smell and colour. These small eggs look dimpled decapsulafion they are dehydrated. Decapsulation consists of chemically removing, in a hypochlorite solution, the shell or chorion of the artemia cysts and leaving only the embryo.

Nowadays, in the culturing of aquatic animals, artemia Aremia salinacommonly called brine shrimp, is decapeulation used in feeding larval or young fish or crustacea. Brine shrimp harvesting companies usually produce the non-hatching decapsulated artemia, and sale them as a non-hatching ingredient to aquaculture arttemia producers that make flake and pellet feeds.

Preservation of decapsulated artemia eggs in refined salt is more efficient than preservation in brine.

Then put them into a filter bag and wash them until they are completely clean. Improvement in the decapsulation of Artemia cysts. Hydrated Decapsulated Brine Shrimp. Instead of preserving decapsulated artemia eggs in strong salt solution brinethey can be kept directly in refined salt.
