Three aromatic sesquiterpene derivatives, (+)-(7R, 10S)-2-methoxy calamenene (1), (+)-(7R, 10S)-2,5-dimethoxy calamenene (2) and (+)-(7R, 10S)-2-methoxy-5-acetoxy calamenene (3) were isolated from the methanol extract of the Indian gorgonian Subergorgia reticulata. Compound 2 has not been previously described in the literature. Compound 3 has not been isolated previously from a natural source. ...

During the present study, we aimed at providing a first look at the elemental composition of the early stages of cephalopods as an approach to their elemental requirements in culture. Essential and non-essential elemental profiles of the European cuttlefish Sepia officinalis, the European squid Loligo vulgaris and the common octopus Octopus vulgaris laboratory hatchlings and wild juveniles were...

This study assessed the performance of a bioluminescent bacterial assay, the ToxScreen-II Test (Photobacterium leiognathi), in comparison to the brine shrimp (Artemia franciscana) nauplii lethality assay for the detection of toxicity associated with Aloe vera leaf gel extract and the organophosphate pesticide Mevinphos. In both bioassays, clear dose-response relationships were demonstrated for ...

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...

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± 2.03...
