The comparison of growth, survival rate and behavior Oscar fish (Astronauts ocellatus) fries fed by Artemia urmiana, earthworm beef heart supplemented diets
چکیده: با توجه به تنوع اکولوژیک ایستگاههای مختلف نمونه برداری دریاچه ارومیه و تفاوتهایی که در صفات بیومتریک سیست و همچنین در برخی صفات ژنتیکی آرتمیای آن مشاهده شده است گمان می رود این دریاچه حاوی جمعیتهای متفاوتی از artemia urmiana باشد. دراین تحقیق سیست آرتمیا از 5 ایستگاه از دریاچه ارومیه صید گردید. مرحله هچ و پرورش ناپلی¬های فوق تا مرحله بلوغ در یک دوره 20 روزه به منظور بررسی رشد و بقاء با ...
due to the importance of adult artemia in aquaculture, information regarding the digestive enzyme activities variation with inexpensive diets has great importance in artemia at different life stages. in this study, the effect of different inexpensive diets on digestive enzyme activities, including trypsin, amylse and lipase of artemia urmiana was investigated in different life stages. the exper...
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± 2.03mg) dur...
In a biogeographical context, the term Macaronesia broadly embraces the North Atlantic archipelagos of the Azores, Madeira, Selvagens, the Canary Islands, and Cape Verde. The peculiar arid climatic conditions in some of these places have led to the development of marine salt exploitations, which can be counted among the hypersaline habitats of the brine shrimp Artemia (Branchiopoda, Anostraca)....

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 میکند. پساب این کارخانه که حدود 5/2 میلیون متر مکعب در سال بوده و در استخرهای خاکی ذخیره میگردد، شور بوده و از نظر خواص فیزیکی و شیمیایی با آب دریاچه ارومی...
This study was conducted to evaluate the efficacy of live food (Artemia urmiana) and commercial diet in rearing of Oncorhynchus mykiss larvae. Experiment started when larvae were 0.12g in weight. Triplicate groups of fish were offered one of four treatments: (1) a commercial starter food (2) live Artemia urmiana nauplii (for 3 days) (3) live Artemia urmiana nauplii (for 7 days) and (4) combin...
Nowadays, nanoparticles (NPs) have the great potential application in different industries. Among all NPs, titanium dioxide NPs is the biggest ecotoxicological and ecophysiology concerns due to the increase of anthropogenic input into the aquatic ecosystems. In this study, the effects of titanium dioxide NPs enriched yeast on the growth, survival; digestive enzymes activity and lipid metabolism...
BACKGROUND Artemia (brine shrimp) is used as feed for fish fry and shrimp in aquaculture. Two employees in a Norwegian aquaculture research farm reported having chest symptoms when working in an Artemia hatch room. AIMS To determine the presence and prevalence of Artemia sensitization at the farm and the extent of any Artemia-related respiratory and hand skin symptoms and to identify the alle...
