GMP reductase in Artemia salina
Biochimica et Biophysica Acta (BBA) - Enzymology, 1974Abstract 1. 1. A GMP reductase (NADPH:GMP oxidoreductase (deaminating), EC 1.6.6.8) activity has been characterized, and partially purified, in Artemia salina extracts. The enzyme is specific for NADPH, has a k m of 0.01 mM for GMP, is maximally active at a pH value of approx. 8.5, requires thiol groups and is resistant to heating at

Adenosine deaminase isozymes in Artemia
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1984Three isozymes of adenosine deaminase, termed II, III and IV, have been detected in Artemia embryos. Their pI values, determined by chromatofocusing, were 4.9, 5.0 and 5.2, respectively. Upon development to larvae, a different isozyme (I) is induced, with a pI value of 4.2 as determined by isoelectric focusing.

Comparative Toxicokinetics of Cadmium in Artemia
Archives of Environmental Contamination and Toxicology, 2005The toxicokinetics of cadmium was determined for five populations belonging to four species of Artemia (A. salina, A. parthenogenetica, A. franciscana, and A. persimilis) using a bicompartmental model. The effects of sublethal cadmium concentration on the kinetic parameters in A. parthenogenetica were determined. The BCF values are inversely related to

Satellite DNA in the crustacean Artemia
Gene, 1986We have isolated a satellite fraction from the Artemia genome by both restriction endonuclease digestion and equilibrium density centrifugation in CsCl gradients containing ligand dye Hoechst 33258. Satellite DNA was arranged in long stretches (approx. 23 kb) of tandem repeats of a basic unit of 113 bp.

The crustacean Artemia franciscana is able to switch between two different reproductive ways controlled by environmental cues: adult females can produce embryos in their ovisac, coated with a thin cuticle shell layer, ready to hatch immediately or metabolically inactive eggs, namely cysts, which undergo diapause in a late gastrula stage.

Scanning electron microscopy provided much details to the external morphology of Artemia. The whole body of Artemia is covered by an extremely thin exoskeleton. In the larval stages the cuticle is 0.3 to 1.0 µm thin and probably has a similar appearance in all regions of the integument.

Developmental changes of Artemia ribonuclease
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1984Encysted gastrulae of Artemia contain a particulate ribonuclease functionally analogous to that present in larvae. This activity is 1/200 times lower than that found in developed larvae and remains constant during embryonic development. Concomitant with the hatching of the larvae, there is a burst in enzyme activity (25-30-fold) and a change in its ...

ENRICHMENT OF Artemia franciscana AND TOXICITY ANALYSIS OF CHLORPYRIFOS ON ENRICHED ARTEMIA
2021The present study highlights the importance of Artemia as a common fish feed worldwide The Artemia cyst were collected, decapsulated, incubated for harvesting, and washed and separated. The Artemia was fed with two different formulations of feed and the growth of Artemia were observed.

Introduction to Artemia Culture
2018Artemia, the brine shrimp, is an excellent live food for cultivable aquatic species. It is in great demand for use in shrimp hatcheries, fish hatcheries and ornamental fish culture farms. The genus Artemia (Leach 1819) is a cosmopolitan taxon that has typically adapted to live in the stressful environmental conditions of higher saline habitats, such as

Adaptation to Hypoxia in Artemia
1989The genus Artemia has diversified to inhabit ecological niches characterized by high salinity and high temperatures. Both of these abiotic environmental factors contribute to a third ecological characteristic of Artemia habitats, i.e. low oxygen content.
