A high-performance liquid chromatography (HPLC) analytical method for the determination of oxolinic acid and flumequine in Artemia nauplii is described. The samples were extracted and cleaned up by a solid-phase extraction (SPE) procedure using SPE C18 cartridges. Oxolinic acid and flumequine were determined by reversed-phase HPLC using a mobile phase of methanol-0.1 M phosphate buffer, pH 3 (4...

Little is known about the basic biology of deep-water coral species. In this study, we experimentally assessed the rates of ingestion of Artemia salina adults and nauplii by the 4 Mediterranean cold water coral species Dendrophyllia cornigera, Desmophyllum cristagalli, Madrepora oculata, and Lophelia pertusa. All species ingested A. salina in adult and nauplii forms. L. pertusa showed the highe...

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 ...

  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...

This study determined the effect of prey DHA on larval gilthead sea bream (GSB; Sparus aurata ) photoreceptor abundance, rhodopsin expression, and growth performance. It was carried out in a twenty-eight 400 l conical tank system that stocked with 100 viable GSB eggs/l/tank. allowed testing 4 levels rotifer DHA; 0.99 (Low; L), 1.9 (Intermediate low; I-L), 3.2 high; I-H) 12.1(High; H) mg DHA/g D...

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...

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...

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 ...

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, ...
