Artemia sp. biomass production using three different microalgae (Pinnularia sp., Porphyridium sp., and Dunaliella sp.) with yeast supply

Abstract

Artemia plays an important role for fish and crustacean fed. The artemia culture system was made in 160 L culture medium at 60 gL-1 salinity. Three experimental diets were made: a) 6 L Pinnularia sp; b) 6 L Porphyridium sp.; and c) 6 L Dunaliella sp. Growth curves were obtained from each experiment. A Life Table was made from each one to obtain the reproductive potential. The highest density value was found in the Dunaliella sp. diet with 85928±233 org 160 L-1, Ro value with 42.25. The lowest density value was obtained with Porphyridium sp. diet con cero value until 39 culture days. Their Ro value was 8.62. The Tc values were similar to the Dunaliella sp. and Pinnularia sp. diet in comparison with the Porphyridium sp. diet. This experiment shows that is necessary to make mixed diets between Pinnularia and Dunaliella to obtain better results of organism densities. The Porphyridium sp. diet cannot be used as the only diet source for Artemia. We suggest that is necessary for Porphyridium sp. diet supply with brown or green microalgae from 21 culture days to complement the nutritional value of the food diet to obtain the biggest rates of survival.
