Excretion rates of ammonia-N, nitrite-N, nitrate-N, and dissolved organic nitrogen (DON) for juvenile Litopenaeus vannamei (3.85+/-0.83 g) were quantified in response to nine different combinations of temperature (24, 28, and 32 degrees C) and salinity (10, 25, and 40 ppt) under laboratory conditions. Results indicated that L. vannamei is ammonotelic, with ammonia-N accounting for 61.9-84.3% of...
White shrimp, Litopenaeus vannamei, which had been injected with chitin at 4, 6 and 8 microg g(-1) or chitosan at 2, 4 and 6 microg g(-1), were challenged with pathogen Vibrio alginolyticus at 2 x 10(6) colony-forming units (cfu) shrimp(-1) and then placed in seawater of 34 per thousand. The survival of shrimp that received chitin or chitosan at either dose was significantly higher than that of...
BACKGROUND Pacific white shrimp (Litopenaeus vannamei), the major species of farmed shrimps in the world, has been attracting extensive studies, which require more and more genome background knowledge. The now available transcriptome data of L. vannamei are insufficient for research requirements, and have not been adequately assembled and annotated. METHODOLOGY/PRINCIPAL FINDINGS This is the ...
The oxidative effects of hydroxyl radicals derived from a FeCl3/ascorbic acid/H2O2 system on the stability muscle proteins in peeled shrimp (Litopenaeus vannamei) were investigated.
bacterial diseases have been reported to be the major limiting factor in shrimp production. the use of natural products such as antimicrobials has been reported as a solution to the problem. the crude extract of a red seaweed laurencia snyderiae obtained from the persian gulf was evaluated for shrimp growth performance and to determine in vivo efficacy of this seaweed in the prevention of shrim...

تاثیر پربیوتیک اینولین بر شاخص های رشد، مورفولوژی روده و پروفیل اسیدهای چرب میگوی وانامی (Litopenaeus vannamei) با وزن متوسط 03/0±21/3 گرم به مدت 5 هفته مورد بررسی قرار گرفت. آزمایش با 3 تکرار درون مخازن پلی اتیلنی مدور با ظرفیت 300 لیتر و با تراکم ذخیره سازی 25 عدد میگو در مرکز آبزی پروری شیلات (استان بوشهر، دلوار) انجام گرفت. اینولین در 2 سطح (صفر و 2 درصد) به جیره...
Methods Serum allergen-specific IgE of 105 subjects were quantified using ImmunoCAP and ImmunoCAP ISAC biochips. The subjects were classified based on a convincing clinical history and food challenge testing (FC) (dose=70g) to Penaeus monodon and Litopenaeus vannamei. Group1A: Either SA with FC positive to either shrimp (n =22) or SA admitted to emergency departments for severe reactions but no...
