Metabolic downregulation during diapause in embryos of Artemia franciscana
Encysted embryos of <i>Artemia franciscana</i> undergo a dramatic respiratory depression upon release from the adult female as they enter a state of hypometabolism termed diapause. The mechanisms by which such a respiratory depression is achieved remain unexplained. Evidence presented here shows …

Protection of Artemia from vibriosis by heat shock and heat shock proteins
… was explored, with gnotobiotic brine shrimp Artemia larvae as the model organism. The thesis contains several findings, featuring the interesting observation that a non-lethal heat shock at 37°C for 30 min followed by a 6 h recovery period and a combined hypothermic/hyperthermic shock with …

Biostabilization of Lipid Bilayers: Dealing with Water Stress in Embryos of Artemia franciscana
… water stress by protectants found in embryos of Artemia franciscana. Two LEA proteins were used: AfrLEA2 and AfrLEA3m. AfrLEA3m was experimentally demonstrated to reside in the matrix. Two detergents were used to differentially solubilize the outer and inner membranes of mitochondria isolated …

The Effect of Highly Unsaturated Fatty Acids (HUFA) on Lake Trout (Salve linus namaycush) Alevins Using Artemia nauplii Enriched with Commercial Emulsions and Dry Diets
… experiments were performed. Diets used in the Artemia Experiment included: diet 1, non-enriched Artemia; diet 2,SELCO-enriched Artemia; diet 3, Super SELCO-enriched Artemia; and diet 4, Bio Vita #0, all of which had significantly different fatty acid compositions. The Fish Oil Replacement …

THE FREQUENCY-DEPENDENCE OF THE NMR LONGITUDINAL RELAXATION RATE, T(1)(-1), OF WATER IN CYSTS OF THE BRINE SHRIMP (ARTEMIA)
… the relaxation rate T(,1)('-1) of water in the Artemia (brine shrimp) cyst is examined as a function of: (1) the proton NMR Larmor frequency for .01 (LESSTHEQ) (omega)/2(pi) (LESSTHEQ) 500 MHz, (2) different cyst hydration levels from 0.12 to 1.25 grams water/gram dry solid, (3) temperatures of …

Enrichment of rotifers (Branchionus plicatilis), Artemia nauplii and artificial dry feed with live yeast (Debaryomyces hansenii) for the growth of cultured dusky kob (Argyrosomus japonicus) larvae
… to larvae using live feeds, such as rotifers and Artemia, and formulated feeds. The dusky kob, Argryosomus japonicus, is emerging as a commercially viable marine aquaculture species in South Africa. However, commercial production of this species is being hindered by parasitic disease. Therefore, …

Practical diet formulation for common carp (Cyprinus carpio) and walking catfish (Clarias macrocephalus) larvae in Thailand
… of diets under conditions of local climate. Live Artemia nauplii, Moina, and practical diets formulated by the National Inland Fisheries Institute (NIFI),Thailand were used as reference diets for assessing the performance of fish fed the experimental diets. Dietary particles size was adjusted to …

Aluminium toxicity (with reference to Copper) in the aqueous environment and the mechanisms of its glutathione-mediated detoxification in the brine shrimp (Artemia franciscana)
… happened to two test species (the brine shrimp Artemiafranciscana and the bacterium Vibrio fischerii), and, in the case of Al, a field study entailing chemical and biological monitoring. In addition, studies were undertaken which showed that Al bioaccumulates in A. franciscana (which is farmed …

Isolation and characterisation of toxins from Fibrocapsa japonica (Raphidophyceae)
… japonica algal cells was first established by Artemia salina biotest. Fibrocapsins was screened step by step through Artemia salina biotest, bioluminescence inhibition biotest and erythrocyte lysis assay methods, isolated then in HPLC. The chemical natures of fibrocapsins 1, 2 and 3 were …

Quroum sensing disruption and the use of short-chain fatty acids and polyhydroxyalkanoates to control luminescent vibriosis
… Vibrio harveyi towards gnotobiotic brine shrimp (Artemia franciscana) nauplii. Subsequently, halogenated furanones were shown to disrupt quorum sensing in these bacteria by decreasing the DNA-binding activity of the quorum sensing master regulator protein LuxR. Interestingly, the addition of 20 mg …
