Ornamental freshwater fish are found in several parts of the world. And tapping the aquarium industry and education are proliferating. Among the many and varied sources of live food, Artemia in aquaculture is important. Because of this, high nutritional value, high digestibility Variation in size, easy production method and salinity tolerance in these animals varied. In this regard, the effects of n-3HUFA and vitamin C-enriched Artemia urmiana nauplii on growth, reproductive performance of swordtail (Xiphophorus helleri). Thus, treatment of fish fed with enriched live feed. Research during the live adult Artemia enriched with fish oil and 5/0 g ascorbic acid treatment in triplicate, Average initial weight of 9/32 and the final weight of 2448 gr with an average survival of larvae from 5/93%, the highest efficiency compared with other treatments. . Maximum number of offspring per generation, the fish fed with concentrate feed 116 infants were living with adult Artemia , Most of the initial weight of the infants were fed with adult Artemia treatment showed no significant difference . The highest sex ratio of offspring of fish fed with concentrate feed is live adult Artemia It is very important that these fish.
