Explaining cases of long-term persistence of parthenogenesis has proven an arduous task for evolutionary biologists. Interpreting sexual-asexual interactions though has recently advanced owing to methodological design, increased taxon sampling and choice of model organisms. We inferred the phylogeny of Artemia, a halophilic branchiopod genus of sexual and parthenogenetic forms with cosmopolitan...

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...

the probiotic effects of two gram positive bacteria, bacillus subtilis and bacillus licheniformis, were examined on growth performance, body composition and survival rate of artemia urmiana. three diets containing 102 (t1), 104 (t2), 106 (t3) cfu of probiotics g feed-1 and a control diet (c) without probiotic were used through a completely randomized design (each with three replicates). the use...

bacillus spp. are gram-positive spore-forming bacteria used commercially as probiotics in the larviculture of fish. bacillus spp. can act positively on cultured organisms by enhancing their survival and growth, stimulating their digestive and immune systems, and improving water quality. in this present study, grass carp larvae were fed on artemia urmiana, artemia fransiscana and artemia parthen...

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 ...

Bacillus spp. are Gram-positive spore-forming bacteria used commercially as probiotics in the larviculture of fish. Bacillus spp. can act positively on cultured organisms by enhancing their survival and growth, stimulating their digestive and immune systems, and improving water quality. In this present study, grass carp larvae were fed on Artemia urmiana, Artemia fransiscana and Artemia parthen...

Abstract:  The surface morphology of resting eggs of Anostracan species from East Azerbaijan Province of Iran and that of Artemia urmiana was compared using Scanning Electron Microscopy (SEM). Anostracan fauna of East Azerbaijan temporary pools were determined as follows: Chirocephalus skorikowi (Chirocephalidae), Branchinecta orientalis (Branchinectidae), Streptocephalus torvicornis (St...

This study was performed to compare the efficiency of six microalgae namely Dunaliella tertiolecta, Tetraselmis suecica, Nannochloropsis oculata, Chaetoceros sp < em>., Chlorella sp. and Spirolina sp < em>. 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....
