Regular, rodlike, macromolecular structures in Artemia salina

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1979
Artemia salina of different origins and in different developmental stages contains regular, rodlike, macromolecular structures. The particles were visualized by electron microscopy after negative staining. They can be purified from the postmitochondrial supernatant by sucrose gradient centrifugation in the presence of EDTA.

Accumulation of cadmium by Artemia salina

Marine Biology, 1979
The relative importance of accumulation of cadmium by Artemia salina (L.) directly from solution and from ingested food has been studied at 3 cadmium concentrations (0.1, 1 and 10 ppm) under controlled experimental conditions. At each cadmium concentration, A.

Carotenoid metabolism in Artemia salina L.

Comparative Biochemistry and Physiology, 1969
Abstract 1. 1. The carotenoid metabolism in Artemia salina has been studied with the feeding of algae Chaetoceras gracilis and pure carotenoids. 2. 2. Artemia salina was unable to metabolize β-carotene to astaxanthin beyond canthaxanthin. 3. 3.

The genetics of Artemia salina: VII. Reproductive isolation

Journal of Heredity, 1976
Fifteen of 20 gonochoristic Artemia populations are crossfertile with diploid San Francisco shrimps, producing fertile F1 and viable F2 progeny. Partial sex linkage of white eye was observed and frequency of crossing over between the white and sex loci did not exceed the range of values observed in San Francisco shrimps.

Acute toxicity of organic solvents on Artemia salina

Bulletin of Environmental Contamination and Toxicology, 1994
Organic solvents can make their way into the environment as industrial wastes and components of pesticide formulation. In laboratory bioassays, the use of organic formulations. In laboratory bioassays, the use of organic solvents is often unavoidable, since many pesticides and organic pollutants have low water solubility and must be dissolved in ...

Ontogenetical studies on extracellular hemoglobins of Artemia salina

Developmental Biology, 1978
Abstract Ontogeny of the three extracellular hemoglobins of zygogenetic races of Artemia salina was studied. Hb-II was the first hemoglobin to appear in the swimming nauplius at about 2 hr posthatching, followed by Hb-III at about 8 hr posthatching. Hb-I was detectable by benzidine-H2O2 staining of cellulose acetate electrophoregrams only after the ...

Neurosecretory cells inArtemia salina L.

Experientia, 1965
Mit der Gomori-Technik wurden beiArtemia drei Typen neurosektretorischer Zellen nachgewiesen. Im Gehirn sind grosse, ovale Zellen mit vakuolisiertem Cytoplasma vorhanden, von denen einige grosse Axone besitzen. Der 2. Typus ist kleiner und weist keine zum Augenstiel fuhrenden Fortsatze auf. Der 3.

The carotenoids of the brine shrimp, Artemia salina

Comparative Biochemistry and Physiology, 1965
Abstract 1. 1. The carotenoid pigments of the Branchiopod crustacean, Artemia salina were studied. They consisted exclusively of the keto-carotenoids, canthaxanthin and echinenone, in a ratio of 19:1. 2. 2. These findings were discussed with relation to the carotenoid pigments in the other sub-classes of crustacea.

Toxicity of Fusarium metabolites to brine shrimps (Artemia salina)

Mycotoxin Research, 1987
Extracts of the followingFusaria cultures, isolated from cereals were examined for toxicity to Artemia salina:F. avenaceum (6 isolates),F. crookwellense (7),F. graminearum (11),F. nivale (5) andF. Sporotrichioides (2). The same cultures, growing on wheat grain, were assayed also mycotoxins presence using TLC method.

ARTEMIA SALINA BIOLOGIYASINING O'ZIGA XOSLIGI

Maqola quyi qisqichbaqasimonlar Artemia salina biologiyasini tavsiflashga bag‘ishlangan. Artemiya qisqichbaqalari baliqlarga ozuqa sifatida ishlatiladi. Yirik baliqlar voyaga yetgan qisqichbaqalarni sevib yeydi, naupliy esa yosh baliqlarni boqish uchun zarur.
