Artemia has been widely used in aquaculture as a suitable live food. The presence of highly unsaturated fatty acids is a key factor that determines the nutritional value and marketing of Artemia for shrimp, marine larvae, sturgeon and ornamental fish industries. To determine the variation in nutritional content in cysts, decapsulated cysts and nauplii of Artemia from three different biotopes of...

The lethal responses to cadmium of instar II nauplii from eight populations of Artemia belonging to the species Artemia franciscana, Artemia salina, Artemia persimilis, and Artemia parthenogenetica have been compared. Generalized linear models were used to fit mortality. The model indicates that there is a relationship between species, type of population, and mortality rate. The two populations...

Growth rate, soluble-protein content, oxygen consumption, ammonia excretion, and digestive-enzyme activity were studied in Litopenaeus setiferus early postlarvae under four feeding regimens that included combinations of freshly hatched Artemia nauplii, microparticulate commercial diet, and algae. Growth and of postlarvae fed a mixed diet were significantly higher. Artificial diet used alone cau...

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...

abstract this study was performed to compare the efficiency of 6 microalgae namely dunaliella tertiolecta, tetraselmis suecica, chlorella sp., (green algae), nannochloropsis oculata, spirolina sp.(blue-green algae) cheatocerus sp. (diatoma),  and isochrices sp. (haptophytae) on the growth, survival and reproduction efficacy in artemia urmiana in laboratory conditions. artemia cysts were harvest...

In the previously published mitochondrial genome sequence of Artemia urmiana (NC_021382 [JQ975176]), taxonomic status examined had not been determined, due to parthenogenetic populations coexisting with A. in Urmia Lake. Additionally, NC_021382 [JQ975176] has obtained pooled cysts (0.25 g consists 20,000–25,000 cysts), a single specimen. With regard Lake, and intra- inter-specific variations sa...

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...
