Instead of preserving decapsulated artemia eggs in strong salt solution brinethey can be kept directly in refined salt. This is used for storage only. Pour off the water produced and store the eggs in shade at normal room temperatures. 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. The eggs of artemia do however have a shell which is dark brown in colour.

They are then ready for hatching or storage in refined salt until required. This experiment introduced new chemical substances for use in the decapsulation process and investigated ways and means of improving and modifying the technique at different stages.

This electronic document has been scanned using optical character recognition OCR software. Stir for 5—8 minutes until the temperature stays steady; this shows that the reaction of the first step of decapsulation has been completed.


Thoroughly rinse until the odor of bleach is gone. The fact that the eggs can be preserved for a long time makes it convenient to hatch them whenever necessary.


Improvement in the decapsulation of Artemia cysts. You now have decapsulated brine shrimp eggs.

Artemia decapsualtion can be preserved in this manner for a long time. This involves the need for a large quantity of brine shrimp eggs.

The sole purpose of links to non-FAO sites is to indicate further information available on related topics. This may take minutes depending on the egg hatch-out, harvest year, etc and sodium hypochlorite solution…however it decapaulation more important to watch the coloration than the minutes. Then put them into a filter bag and wash them until they are completely clean. A modified technique has been developed whereby decapsulation is conducted by using calcium oxide and calcium hypochlorite as stimulating agents.

Additionally the deapsulation for the preservation of decapsulated artemia eggs has been improved by a more efficient method. The artemia is a very tiny animal which has no shell.

After the eggs have been decapsulated, transfer them into a filter bag. Comparison of the hatching efficiency of non-decapsulated artemia eggs, eggs decapsulated by sodium hypochlorite and those decapsulated by calcium hypochlorite bleaching powder.

Siphon all these eggs out and discard if the quantity of incompletely decapsulated eggs is large however, decapsulatipn can be stored in refined salt until the next decapsulation process. Monitoring the color is very important if decapsulating for live hatchings.

However, the eggs which are not completely bleached as well as some dirt will be floating on the surface. Nowadays, in the culturing of aquatic animals, artemia Aremia salinacommonly called brine shrimp, is widely used in feeding larval or young fish or crustacea. Hyperlinks to non-FAO Internet sites do not imply any official endorsement of or responsibility for the opinions, ideas, data or products presented at these locations, or guarantee the validity of the information provided.

Once the orange color is reached the reaction must be neutralized. Shrimp and fish hatcheries use their lower grade egg to produce a live or hatching decapsulated egg.

After cleaning transfer the eggs back into the plastic containers. Add the hydrated egg into sodium hypochlorite and aerate again from the bottom.

Artemoa hatcheries and brine shrimp harvesting companies use decapsulation to get a greater return from lower grade egg. This site uses cookies. The whole procedure, including both stage will now have taken 10—16 minutes.
