The hemoglobin molecule of the commercially important brine shrimp Artemia sp. has been used extensively as a model for the study of molecular evolution. It consists of nine globin domains joined by short linker sequences, and these domains are believed to have originated through a series of duplications from an original globin gene. In addition, in Artemia, two different polymers of hemoglobin...

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, ...

effects of using n-3 hufa-enriched artemia and non-enriched artemia as the starter food for growth and survival of rainbow trout larvae compared to commercial concentrated food were investigated in this study. the larvae with average weight of 92.9 mg were fed for 20 days with four food treatments included of commercial concentrated food, newly hatched artemia, enriched artemia, and mixture of ...

The experiment was conducted to investigate the effects of artemia enriched with lipid emulsions containing highly unsaturated fatty acids on growth and survival of juvenile freshwater crayfish Astacus leptodactylus. Juvenile crayfish were fed artemia enriched with commercial emulsions (red pepper and olio ω3) and un-enriched artemia (control). The highest eicosapentaenoic acid (EPA) level was ...

brine shrimp artemia, is a small crustacean which is found naturally in salt lakes and lagoons. sofar several bisexual and parthenogenetic artemia populations have been reported which have different phenotypic and genotypic characters. the biological properties of some populations has not been studied yet. regarding that the populations of turkey have not been characterized so far, in present s...

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...

Effects of Artemia urmiana enriched with ICES30/4 as a commercial emulsion of highly unsaturated fatty acid (HUFA) on growth, survival, salinity tolerance and fatty acid composition of the Persian sturgeon larvae were evaluated. Artemia enriched for two different time periods (12 and 24 hours) and non-enriched artemia were fed to A. persicus larvae (average initial wet weight 46.80± 2.03mg) dur...

abstract: chitosan is a natural antimicrobial which is derived from non-toxic animal resources. this study investigated and compared the antimicrobial characteristics of chitosan which was extracted from shell of artemia cyst in the lake of urmia with the same commercial chitosan feature to that of crab shell from a.p.t firm in vietnam. the experiment was carried by means of two fulded method t...

The brine shrimp Artemia is a micro-crustacean, well adapted to the harsh conditions that severely hypersaline environments impose on survival and reproduction. Adaptation to these conditions has taken place at different functional levels or domains, from the individual (molecular-cellular-physiological) to the population level. Such conditions are experienced by very few equivalent macro-plank...
