The brine shrimp Artemia is a micro-crustacean, well adapted to the harsh conditions that severely hypersaline environments impose on survival and reproduction. Adaptation to these conditions has taken place at different functional levels or domains, from the individual (molecular-cellular-physiological) to the population level. Such conditions are experienced by very few equivalent macro-plank...

in this study the optimal amount of enriching artemia franciscana with a synbiotic combination of pediococcus acidilactici and fructooligosaccharide (fos( was investigated. the experiment was conducted in a completely randomized design in ten treatments: multi-level probiotics p. acidilactici (1×109, 1×108 and 1× 107 cfu per l) and multi-level enriched prebiotic fos (1, 2 and 5) g per l of solu...

A 15-day study was conducted to evaluate the effects of Artemia metanauplii enriched with two commercial supplements (Easy DHA-Selco and S. presso) which contained high levels of n–3 long chain polyunsaturated fatty acids (n–3 LC-PUFA) on growth performance, stress resistance and fatty acid profile of Litopenaeus vannamei post larvae (PL). In this regard, PL were fed with three different types ...

This study was carried out in a completely randomized design 3×3×4 factorial arrangement in three periods of rearing in spring 1997. Density of 300 larvae was assigned for each oval tank with 0.1m2 surface area, 30cm deep, a volume of 20lit and 0.25 lit/min of water flow per minute at Shahid Rajaie fish breeding and culture center in Sari, north of Iran. The fries were divided into ...

Adenine phosphoribosyltransferase (APRTase) and hypoxanthine-guanine phosphoribosyltransferase (HGPRTase) have been purified from Artemia cysts and nauplii to apparent homogeneity, as determined by SDS-PAGE. The purification includes affinity chromatography on AMP-Sepharose, which binds both enzymes, and they are eluted at different 5-phospho-alpha-D-ribosyl diphosphate (PP-Rib-P) concentration...

This paper reports an effective and easy method to culture the ctenophore Bolinopsis mikado. Fifteen adult B. mikado individuals were maintained in a kreisel tank, fertilized eggs, which detected following days, all raised together same tank. From early development stage day 13, cydippid larvae only fed Artemia nauplii. The able easily catch nauplii excreted by mikado; therefore, they considere...

This article presents materials on the results of an experiment enrichment Artemia salina with unicellular alga Haematococcus pluvialis to increase its nutritional value. For fry marine fish, such as mullet and kalkana, freshwater clary catfish, carp trout, supply fatty acids energy value is still insufficient. Therefore, it necessary enrich brine shrimp additional nutrients The use a component...
