Hemocyanin is a copper-containing protein with immune function against disease. In this study, a hemocyanin subunit named MnHc-1 was cloned from Macrobrachium nipponense. The full-length cDNA of MnHc-1 was 2,163 bp with a 2,028-bp open reading frame (ORF) encoding a polypeptide of 675 amino acids. The MnHc-1 mRNA was expressed in the hepatopancreas, gill, hemocytes, intestine, ovary, and stomac...
BACKGROUND The oriental river prawn (Macrobrachium nipponense) is the most prevalent aquaculture species in China. The sexual precocity in this species has received considerable attention in recent years because more and more individuals matured at a small size, which devalues the commercial production. In this study, we developed deep-coverage transcriptomic sequencing data for the ovaries of ...

Microcystins (MCs) are a major group of cyanotoxins with side effects in many organisms; thus, compounds in this group are recognized as potent stressors and health hazards in aquatic ecosystems. In order to assess the toxicity of MCs and detoxification mechanism of freshwater shrimp Macrobrachium nipponense, the full-length cDNAs of the glutathione S-transferase (gst) and catalase (cat) genes ...
The present study showed the effect of water currents (0.20 – 0.25 m\sec.) on movement behaviour Macrobrachium nipponense during 2 and 24 hour periods inclusive weight group five (g) . In first period, results indicated that one (0.10 0.49 g) aggregated towards or contrary by relative percentage 64.47 & 35.33 % , where as groups were distributed in following sequences : two three four 44 56...
We identified the cDNA sequence of cathepsin L (CatL) in Macrobrachium nipponense, designated as MnCatL, for the first time. The MnCatL cDNA, isolated from the ovary, was 1710 bp in length, containing a 31-bp 5'-untranslated region, a 650-bp 3'-untranslated region, and an open reading frame of 1029 bp, encoding a 342-amino acid polypeptide with a predicted molecular mass of 37.7 kDa. The polype...
The scavenger receptor class B, type I (SR-BI), is a member of the CD36 superfamily comprising transmembrane proteins involved in mammalian and fish lipid homeostasis regulation. We hypothesize that this receptor plays an important role in Macrobrachium nipponense lipid metabolism. However, little attention has been paid to SR-BI in commercial crustaceans. In the present study, we report a cDNA...
یک بررسی تغذیه ای در مدت 8 هفته بروی میگوهای جوان آب شیرین انجام شد.این آزمایش برای ارزیابی عملکرد جیرهای حاوی 0(کنترل) ، 5/0 ،1و5/1 گرم پروبیوتیک درهر کیلوگرم بود.240 عدد میگوی جوان آب شیرین با میانگین وزنی (گرم1/0±4/.) بطور کاملا تصادفی بین 12 آکواریوم 100 لیتری توزیع شدند. میگوها در حد اشباع روزانه دو بار(8و20) مورد تغذیه قرار گرفتند .شاخص های رشد در میگوهای آب شیرین از قبیل درصد افزایش وزن ...
به منظور بهبود شرایط رشد گونه های پرورشی، تعیین سطوح مناسب مواد مغذی انرژی زا، به ویژه میزان کربوهیدرات، ضروری است. با توجه به اینکه تاکنون مطالعات جامعی دربارة نیازهای غذایی با تأکید بر اثر کربوهیدرات در این گونه انجام نشده است، از این رو آزمایشی تغذیه ای به منظور بررسی اثر مقادیر مختلف کربوهیدرات در عوامل رشد و ترکیب شیمیایی بدن میگوی رودخانه ای شرق انجام شد. پنج سطح 15، 20، 25، 30 و 35 درصد ...
The gene female sterile homeotic (fsh) plays crucial roles in molecular function, including protein kinase activity and DNA binding, which are involved in biological processes such as terminal region determination and negative regulation of DNA-dependent transcription. Although fsh has been found in Drosophila melanogaster, little is known regarding its expression in crustaceans. In this study,...
