The effects of using n-3 LC-PUFA -enriched Artemia nauplii and newly hatched Artemia on survival and resistance to pH stress in larvae of angel fish (Peterophylum scalar) were examined In tow 20 days period. In the first step of the experiment the larvae with an average weight of 0.86 ±0.03mg were fed with tow diets (enriched Artemia nauplii and newly hatched Artemia) for 20 days. At the end of the first step of the experiment, the significantly (p<0.05) higher survival rate was observed in larvae fed with enriched Artemia (90.66%) than the larvae fed with newly hatched Artemia (83.66%). In the second step of the experiment the larvae with an average weight of 20. 03 ±3.73mg were fed only with commercial diet for 20 days. At the end of the second 20th days of the experiment, larvae exposed at pH stress (including 5.5, 6.5, 8.8 and 9.5) for 96 hours. The Result showed that the larvae were fed with n-3 LC-PUFA-enriched Artemia have a higher significant survival rate than other group in the period of the experiment and pH stress (p<0.05). Therefore, using of n-3 LC-PUFA-enriched Artemia recommended for increasing survival rate and the resistance to pH stress.
