Nauplii of the brine shrimp Artemia sp. are optimal starter food for many fish and crustaceans species. For this reason, technologies their production being improved, including activation cysts. The effect different concentrations hydrogen peroxide on hatching process a as activator was studied. Its concentration has been determined; it amounts to 0.2-0.4 ml/l. reasons various impacts cysts for...

Although there is growing evidence that metals can be toxic to various aquatic species, there is still insufficient knowledge to integrate this information in environmental risk assessment procedures. In this study, we have investigated bioaccumulation and effects of nickel and vanadium on mortality and growth of Artemia urmiana and Artemia franciscana. The in 24 h of A. urmiana and A. franci...

This study was performed to compare the efficiency of six microalgae namely Dunaliella tertiolecta, Tetraselmis suecica, Nannochloropsis oculata, Chaetoceros sp., Chlorella sp. and Spirolina sp. on the growth, survival rate and reproduction efficacy in Artemia urmiana in laboratory conditions. Artemia cysts were harvested from Urmia Lake and hatched according to the standard method. Live microa...

Internal and external feeding on zooplankton may provide scleractinian corals with important nutrients. However, the latter process has never been properly quantified. To quantify the dynamics of zooplankton capture, digestion and release for a scleractinian coral, we performed detailed video analyses of Galaxea fascicularis feeding on Artemia nauplii. A highly dynamic process of prey capture, ...

The oxidative stability and the particle size of several types of liposomes were assessed in order to characterize their behaviour when submitted to the aggressive conditions of the Artemia enrichments. Results show that all liposomes tested in this study were much more oxidatively stable than a commercial product based on fish oil emulsion. Whereas the initial thiobarbituric acid reactive subs...

artemia plays a major role in aquaculture as one of the most important live foods used in larval rearing. the aim of this study was to determine the optimum level of feeding in artemia urmiana with baker's yeast (saccharomyces cerevisiae). triplicate groups were fed with different levels of s. cerevisiae yeast 0.625 (control), 1.25 (t1), 2.50 (t2), 5.0 (t3) (mg yeast per 1000 nauplii) for ...
