Artemia franciscana C. Drewes (updated, 2002) http://www.zool.iastate.edu/~c_drewes/ http://www.zool.iastate.edu/~c_drewes/Artemph.jpg Taxonomy Phylum: Arthropoda Subphylum): Crustacea Class: Branchiopoda (includes fairy shrimp, brine shrimp, daphnia, clam shrimp, tadpole shrimp) Order: Anostraca (brine shrimp and fairy shrimp) Genus and species: Artemia franciscana (= the North American versio...
The use of juvenile Artemia as feed in aquaculture and in the pet shop industry has been getting more attention during the last decade. In this study, the use of selected bacterial strains to improve the nutritional value of dry food for Artemia juveniles and to obtain control of the associated microbial community was examined. Nine bacterial strains were selected based on their positive effect...
The lethal responses to cadmium of instar II nauplii from eight populations of Artemia belonging to the species Artemia franciscana, Artemia salina, Artemia persimilis, and Artemia parthenogenetica have been compared. Generalized linear models were used to fit mortality. The model indicates that there is a relationship between species, type of population, and mortality rate. The two populations...
هدف از انجام این پروژه بررسی کمی وکیفی پساب کارخانه کاوه سودا جهت پرورش آرتمیا به منظور استفاده بهینه از پساب کارخانه است. کارخانه کاوه سودای مراغه که در موقعیت جغرافیایی طول شرقی و عرض شمالی واقع شده است، و سدیم کربنات سبک و سنگین تولید می کند. پساب این کارخانه که حدود 5/2 میلیون متر مکعب در سال بوده و در استخرهای خاکی ذخیره می گردد، شور بوده و از نظر خواص فیزیکی و شیمیایی با آب دریاچه ارومی...
The genetic variability at enzyme loci in different triploid and tetraploid parthenogenetic weevil populations has been elucidated by starch gel electrophoresis. The overall genotype of individual weevils belonging to different populations has been determined for over 25 loci. The results are compared with those obtained for diploid bisexual races of either the same or closely related species. ...
BACKGROUND Prior research on the microorganisms associated with the brine shrimp, Artemia franciscana, has mainly been limited to culture-based identification techniques or feeding studies for aquaculture. Our objective was to identify bacteria and archaea associated with Artemia adults and encysted embryos to understand the role of microbes in the Artemia life cycle and, therefore, their impor...
Parthenogenetic lineages that arise in a hermaphroditic, sexual population will inherit the male function from their sexual progenitors. Natural selection then acts to reduce male allocation of the parthenogens, freeing resources presumably for the female function. Depending on age and the available genetic variation, one therefore expects to find reduced male allocation in naturally occurring ...
Induced pluripotent stem cells (iPSCs), generated from somatic cells by overexpression of transcription factors Oct4, Sox2, Klf4 and c-Myc have the same characteristics as pluripotent embryonic stem cells (ESCs). iPSCs reprogrammed from differentiated cells undergo epigenetic modification during reprogramming, and ultimately acquire a similar epigenetic state to that of ESCs. In this study, the...
The brine shrimp, Artemia, reproduces either oviparously, producing encysted embryos (diapause cysts), or ovoviviparously, producing free-swimming nauplii. Environmental factors, such as photoperiod, have been applied to control the reproduction mode of Artemia, but when the determination of a reproductive mode occurs remains unknown. We analysed the differential gene expression between oocytes...
ARTEMIA is commonly known as the brine shrimp. It is a crustacean. It lives high saline waters. It is widely distributed throughout the world; it is the most important live feed organism. ARTEMIA lives in high saline environment where its predators cannot survive. Hence ARTEMIA can be effectively cultured in saline water. Such water bodies are found in solar saltpans, which occur all along Indi...
