Salinity and water temperature optimization for HUFA enrichment of Artemia urmiana nauplii with emulsion ICES
چکیده
Enrichment of live food with HUFA, specially EPA and DHA for marine fish's larviculture is necessary for increasing survival and growth rates.
During this research, Artemia urmiana nauplii were enriched with ICES???????????????? for ????????h. The variables used in this experiment were different salinities of ????????, ???????? and ????????ppt. and temperatures of ????????, ???????? and ????????°C in three replications. The fatty acid contents of Artemia
samples from each experiment were measured with GC. Statistic design used was completely randomized design with Dunkan's Test. Results showed rather high increase of fatty acids of EPA and DHA, this increase was from ???????????? in control to ???????????????? percent for EPA at ????????°C and salinity of ????????ppt. (P<????????????????????????) and for DHA from ???? to ???????????? percent at ????????°C and ????????ppt. salinity. The best condition for DHA:EPA ratio is ????????ppt and ????????°C (P<????????????????).
