Vanhaecke, P.; De Vrieze, L.; Tackaert, W.; Sorgeloos, P. (1990). The use of decapsulated cysts of the brine shrimp Artemia as direct food for carp Cyprinus carpio L. larvae. J. World Aquacult. Soc. 21(4): 257-262
Decapsulated Artemia cysts have been evaluated as a direct food source for larvae of the carp Cyprinus carpio L. All decapsulated cyst diets gave excellent survival of carp larvae during the first two weeks of culturing. Unlike traditionally brine-stored decapsulated cysts, dried Artemia embryos provided growth results comparable to those obtained with freshly hatched Artemia nauplii. Furthermore, except for Artemia embryos that lost their hatchability after long-term storage in air, several other inactivation treatments, simulating improper harvesting and processing of cysts, did not produce a significant decrease in the nutritional quality of the decapsulated cysts.
Using decapsulated cysts as a direct food source for carp larvae, instead of nauplii, the quantity of cysts needed can be reduced by about 25% to 35% after one and two weeks of culturing, respectively. Moreover, the use of decapsulated cysts advances the possible commercialization of poor hatching and less expensive cyst products for culture of carp larvae.
