The effect of Artemia Urmiana nauplii enriched with Viramin C on percentage of survival in postlarvae Penaeus Semisulcatus
The use of live food in larval aquaculture has got proportion the normal regiment. Using enrichment technique , the amount of some essential nutrients, vitamins etc, can increase in live food which is important in improving the quality consumer larvae, Ascorbic acid (AA) is an essential nutrient in live aqua feeds. During the hatching process cyst under name ascorbic acid 2-sulfate (AAS) stable form is converted to ascorbic acid (AA) , a more unstable form . Because of lack synthesis amount enough of vitamin C for the .shrimp _that required supportion by food rationing, with directly available in the artemia nauplious for the shrimp larvae. With using enrichment technique for the improvement of status vitamin C in artemia nauplious order to perform this technique, we use ascorbyl Palmitate (AP) which is fat-solutoin and is converted to ascorbic acid (AA) in consumer body larvae. In this study the effects of Artemia urmiana nauplii enriched with vitamin C including four treatments under name, witness of nauplii, enriched nauplii with 0%(for control emulsion ICSE) , 10% and 20% AP in the feeding Green Tiger shrimp (Penaeus semisulcafus) postlarvea at PLI to PLI 4 stage were assessed with comparison of survival rate in postlarvea period,we will conclude the best enrichment percentage that the role of artemia nauplious in survival and increasing resistance against with effective and stressful condition. Results with using ANOVA &Duncan test by SPSS software were analyzed. Postlarvae fed with witness and 0% enriched nauplii has not its effect to increase survival rate in post larvae whereas this result were reverse in 10% and 20% enriched nauplious . The highest percentage of survival is belonging to postlarvae fed with nauplious enriched with 20% in days during 5-7. This indicated that with increasing enrichment percentage in nauplious the survival rate of post larvae is increase too.
