Nowadays, biometrical characterizations of Artemia cysts are used as one of the most important factors in the study of Artemia populations and intraspecific particularity; meanwhile these characters can be used as economical indices. For example, typically high hatching efficiency is possible due to the small diameter of cysts (high number per gram); therefore small diameter of cysts show somew...

This is the first study on phylogenetic relationships in the genus Artemia Leach, 1819 using the pattern and sequence of secondary structures of internal transcribed spacer 1 (ITS1). Significant intraspecific variation in the secondary structure of ITS1 rRNA was found in Artemia tibetiana. In the phylogenetic tree based on joined primary and secondary structure sequences, Artemia urmiana and pa...

Abstract Brine shrimps ( Artemia ) have undergone geographic range and demographic expansions as a result of their interaction with humans since the beginning salt harvesting. This has favoured expansion some species but compromising survival others. Mediterranean native populations salina from coastal salterns lagoons are facing presence introduced invasive American monica (= A . franciscana )...

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...

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...

Contagious parthenogenesis-a process involving rare functional males produced by a parthenogenetic lineage which mate with coexisting sexual females resulting in fertile parthenogenetic offspring-is one of the most striking mechanisms responsible for the generation of new parthenogenetic lineages. Populations of the parthenogenetic diploid brine shrimp Artemia produce fully functional males in ...
