Abstract
Background:
Artemia is considered an indispensable live food for rearing many
fish and crustacean larvae and can be used in toxicity tests as a safe, practical, and economical
method. It is straightforward to create and manipulate; however, many cysts do not
hatch as expected.
Methods:
A new device was used to hatch Artemia salina. The device includes a tubularshaped
reservoir, lid with a central hole, heater with a thermostat, air compressor, three porous
stones, funnel-shaped bottom, light source, collection valve, switch, and electrical outlet,
which permits better control of temperature and aeration in a single apparatus. Different
patent devices were used for comparative analysis.
Results:
Hatched eggs of Artemia showed that the device was 97% efficient; in comparison,
commercial and other devices hatched approximately less than 80% of the cysts. Although
Artemia is an easy-to-handle animal, the device described here facilitates changes in
the growth parameters and produces more nauplii larvae.
Conclusion:
This paper presents a new device that is effective, compact, and successful for
hatching brine shrimp cysts, thereby improving Artemia production.
