Artemia urmiana nauplii were enriched with three different concentrations (100, 200 and 300 ppm) of commercial emulsion, ICES/30/4 during two periods (12 and 24 h) to evaluate the enhancement of its Highly Unsaturated Fatty Acids (HUFAs). This source was selected because of its high concentration of the longest chain HUFA's in the n-3 and n-6 series. When 24-h-old Artemia nauplii were enriched ...

  This study was conducted to evaluate the efficacy of live food (Artemia urmiana) and commercial diet in rearing of Oncorhynchus mykiss larvae. Experiment started when larvae were 0.12g in weight. Triplicate groups of fish were offered one of four treatments: (1) a commercial starter food (2) live Artemia urmiana nauplii (for 3 days) (3) live Artemia urmiana nauplii (for 7 days) and (4) combin...

due to the importance of adult artemia in aquaculture, information regarding the digestive enzyme activities variation with inexpensive diets has great importance in artemia at different life stages. in this study, the effect of different inexpensive diets on digestive enzyme activities, including trypsin, amylse and lipase of artemia urmiana was investigated in different life stages. the exper...

Enrichment of live foods by essential nutrients such as highly unsaturated fatty acids is an important tool for improvement of larval fish quality. In this study, nutritional effects of Artemia urmiana enriched by fish and plant oils on growth, survival rate, body compositions and resistance against thermal, salinity and hypoxic stresses in rainbow trout, Oncorhynchus mykiss were examined. Six ...

background: artemia urmiana are small crustaceans that because of its non-selective filter feeder pattern potentially may absorb high level of heavy metals through their living environment. in this study, the effects of different levels of cadmium and copper on survival, catalase activity and metals bioconcentration rates in a. urmiana nauplii have been investigated. methods: the research was c...

The effect of salinity on cadmium uptake and elimination by brine shrimp Artemia urmiana which lives only in Urumieh Lake, Iran, was studied for the first time. Brine Shrimp were acclimated to different salinities and exposed to the metal in solution at differing salinities and composition. Experimental salinities ranged from 50 to 125 gL and the concentrations for cadmium added to the solution...

bacillus spp. are gram-positive spore-forming bacteria used commercially as probiotics in the larviculture of fish. bacillus spp. can act positively on cultured organisms by enhancing their survival and growth, stimulating their digestive and immune systems, and improving water quality. in this present study, grass carp larvae were fed on artemia urmiana, artemia fransiscana and artemia parthen...

This study was accomplished to investigate the effect of Artemia urmiana nauplii enriched with Pediococcus acidilactici as probiotic on growth performance and survival rate of great sturgeon, Huso huso.  Artemia nauplii were enriched with P. acidilactici at a final concentration of 1010 CFU mL-1 in three time dependent treatments as 3 h (T3), 6 h (T6), 9 h (T9), and one non-enriched Artemia as ...
