Evaluation of growth and survival rate of Artemia parthenogenetica feed with micro algae (Isochrysisand Chlorella vulgaris)and bakery yeast(Saccharomyces cerevisiae)

International journal of the bioflux society 01/2011; 4:463-468.


This study was done to evaluate growth and survival rate of Maharloo lake artemia (Artemia
parthenogenetica) (Bowen & Sterling, 1978) which feed with two species of microalgae (Isochrysis galbana and Chlorella vulgaris) and bakery yeast (Saccharomyces cerevisiae) with different nutritious ingredients for 15 days. We evaluated them in 3rd, 7th, 11th and 15th days of cultivation period for 4 times. This experiment was done in completely randomized design with 4 treatments (3 treatments and 1 control) and each treatment has 3 replicates. Artemia parthenogenetica nauplii were feed with three different types of food that includes Isochrysis galbana microalgae (T1), Chlorella vulgaris (T2) and Saccharomyces cerevisiae yeast (T4). Control had feed with blend of these three matters. After 15 days the highest survival rate was observed in control (84.00) and the lowest one was related to the T4 (59.58) which feed with Saccharomyces cerevisiae yeast (p<0.05). The highest growth rate was observed in T4, T3, followed by T1 and T2 respectively. Achievement results showed significant differences between control and other treatments (p<0.05). This study proved that treatments which feed with blend of two micro algae's species and bakery yeast have higher survival ability than the other treatments.
