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...

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....

Although there is growing evidence that metals can be toxic to various aquatic species, there is still insufficient knowledge to integrate this information in environmental risk assessment procedures. In this study, we have investigated bioaccumulation and effects of nickel and vanadium on mortality and growth of Artemia urmiana and Artemia franciscana. The in 24 h of A. urmiana and A. franci...

Feeding farmed Artemia with yeast heat shock proteins is a novel way to protect them from stress conditions during the culture.  In this study, the effect of feeding with stressed new identified Saccharomyces cerevisiae strain YG3-1 yeasts (containing induced heat shock proteins) on the survival of Artemia in stress conditions, was evaluated. For this purpose, heat shock proteins 82 (Hsps 82) o...

BACKGROUND Prior research on the microorganisms associated with the brine shrimp, Artemia franciscana, has mainly been limited to culture-based identification techniques or feeding studies for aquaculture. Our objective was to identify bacteria and archaea associated with Artemia adults and encysted embryos to understand the role of microbes in the Artemia life cycle and, therefore, their impor...

The brine shrimp, Artemia, reproduces either oviparously, producing encysted embryos (diapause cysts), or ovoviviparously, producing free-swimming nauplii. Environmental factors, such as photoperiod, have been applied to control the reproduction mode of Artemia, but when the determination of a reproductive mode occurs remains unknown. We analysed the differential gene expression between oocytes...

ARTEMIA is commonly known as the brine shrimp. It is a crustacean. It lives high saline waters. It is widely distributed throughout the world; it is the most important live feed organism. ARTEMIA lives in high saline environment where its predators cannot survive. Hence ARTEMIA can be effectively cultured in saline water. Such water bodies are found in solar saltpans, which occur all along Indi...

The present study evaluates the feasibility of using Artemia franciscana in reducing the Ni concentration of synthetic wastewater by the process of bioaccumulation. Metallothionein protein plays a key role in the uptake of nickel by Artemia. Artemia (Brine shrimp) was exposed to an initial nickel concentration of 40 mg/L. Gradual decrease of nickel was observed from 40 mg/L to 5 mg/L with a rem...

The protein p26 is a small heat shock protein that functions as a molecular chaperone to protect embryos by preventing irreversible protein damage during embryonic development. A 542 bp fragment of the p26 gene was cloned and sequenced. The fragment encoded 174 amino acid residues and the amino acid sequence contained the alpha-crystallin domain. Phylogenetic analysis showed that eight Artemia ...
