Eriocheirsinensis, Portunus trituberculatus and Scylla paramamosain are important commercial culture crab species in China. Traditional factory breeding of crabs depends on Artemia nauplius. The rising price of Artemia cysts has led to the decline of the economic benefit of the crab breeding factory. Factory crab breeding has been gradually replaced by pond breeding in recent years. E. sinensis...

Male and female Artemia salina swim in tandem pairs before copulation and during this period the metachronal rhythms of the individuals are entrained. Artemia entrain to pulsatile water stimulation of the head at frequencies between 4 and 6 Hz. The antennules are mechano-sensitive. Antennular responsiveness to phasic input is very probably the actual mechanism by which interorganism co-ordinat...

A selection of isogenic yeast strains (with deletion for genes involved in cell-wall synthesis) was used to evaluate their nutritional and immunostimulatory characteristics for gnotobiotically-grown Artemia. In the first set of experiments the nutritional value of isogenic yeast strains (effected in mannoproteins, glucan, chitin and cell-wall bound protein synthesis) for gnotobiotically-grown A...

BACKGROUND As a response to harsh environments, the crustacean artemia produces diapause gastrula embryos (cysts), in which cell division and embryonic development are totally arrested. This dormant state can last for very long periods but be terminated by specific environmental stimuli. Thus, artemia is an ideal model organism in which to study cell cycle arrest and embryonic development. PR...

Endemic Artemia franciscana populations can be found throughout the American continent and also as an introduced specie in several country all over the world, such as in the Mediterranean region where Artemia franciscana was identified as an invasive specie replacing native Artemia parthenogenetica and Artemia salina. In the present study, the characterization of the new invasive Artemia franci...

The present study revealed the toxic effect of silver nanoparticles (AgNPs) in Artemia nauplii and evaluated the mortality rate, hatching percentage, and genotoxic effect in Artemia nauplii/cysts. The AgNPs were commercially purchased and characterized using field emission scanning electron microscope with energy dispersive X-ray spectroscopy. Nanoparticles were spherical in nature and with siz...

The effect of diet on larval growth, anionic trypsinogen gene expression (ssetryp1), and trypsin (EC 3.4.21.4) and chymotrypsin (EC 3.4.21.1) activities was assessed in Solea senegalensis. Changes in larval carbon stable isotope (δ(13)C) composition were used to estimate carbon assimilation. Diets were supplied for 20days to fish held in larval rearing tanks and consisted of live rotifers, Arte...

Chitosan (CS) was prepared from Artemia urmiana cyst shells using the same chemical process as described for the other crustacean species, with minor adjustments in the treatment conditions. The influence of modifications of the CS production process on the physiochemical and functional properties of the CS obtained was examined. The study results indicate that Artemia urmiana cyst shells are a...

To evaluate the effect of two bacterial strains isolated from Artemia cysts and yeast (Candida utilis) on the survival, growth and total biomass production of its larvae, challenge tests were performed with Candida utilis, Pseudomonas stutzeri and Pasteurella haemolityca. In addition, a pathogenic strain of Vibrio alginolyticus was tested for comparative purposes. Pseudomonas stutzeri and Candi...
