Effect of methylparaben in Artemia franciscana
Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2017In this study, the toxicity of methylparaben (MeP) an emerging contaminant, was analysed in the sexual species Artemia franciscana, due to its presence in coastal areas and marine saltworks in the Mediterranean region. The acute toxicity (24h-LC50) of MeP in nauplii was tested and its chronic effect (9days) evaluated by measuring survival and growth ...

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.

Roux's Archives of Developmental Biology, 1996
We have studied the process of post-embryonic segmentation in the anostracan crustacean Artemia franciscana using a specific antibody raised against the engrailed protein of this organism. Three cephalic segments are specified during embryonic development, before larval hatching, whilst trunk (thoracic) segmentation begins after the first stage free ...

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.

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 ...

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
