A Study on the Meat and Bone Meal or Poultry By-product Meal as Protein Substitutes of Fishmeal in Concentrated Diets for Paralichthys olivaceus

A study was conducted to evaluate the effects of meat and bone meal (MBM) and poultry by-product meal (PBM) as the replacement of fishmeal in the diets on the growth performance, survival and apparent digestibility coefficient (ADC) of Japanese flounder (Paralichthys olivaceus). The experimental diets included 0%, 20%, 40%, 60% and 80% MBM or PBM replacement of total  (本文共4页) 阅读全文>>

MiR-430 Can Affect the Mesoderm Formation and Metamorphosis of Paralichthys olivaceus by Targeting lefty Gene

MiR-430 is a non-coding small RNA that participates in early embryonic development by acting on the Nodal signaling pathway. Its functions in Paralichthys olivaceus(P. olivaceus), however, remain unclear. In this study, through biological information technology, we hypothesized lefty was the target gene of miR-430. Lefty is a divergent member of the transforming growth factor-β(TGF-β) superfamily, and is involved in ...  (本文共8页) 阅读全文>>

Carbon Budget of Bastard Halibut Paralichthys Olivaceus in Relation to Body Weight and Temperature

The effects of body weight and temperature on the carbon budget of the juvenile bastard halibut,Paralichthys olivaceus, were studied at temperature 13.5, 18, 21.5 and 24 ℃, respectively. The carbon intake, faecal and growth carbon were measured, and the carbon respiration was calculated using the ca...  (本文共7页) 阅读全文>>

牙鲆(Paralichthys olivaceus)CD59基因的原核表达与功能探究

本研究分析了CD59基因在牙鲆(Paralichthys olivaceus)感染鳗弧菌(Vibrio anguillarum)前后的表达模式。结果显示,感染前,CD59基因在检测的4种免疫器官中均不表达;感染后,该基因均有不同程度的表达,其中,肾脏的表达量最高。对牙鲆CD59基因进行原核表达,构建原核表达载体pET-32a-CD59,并将其转化入大肠杆菌(Escherichia coli)BL21,使用异丙基-β-D-硫代半乳糖苷(IPTG)诱导,获得约为29 kDa的重组蛋白pET-3...  (本文共8页) 阅读全文>>

The effects of temperature and substrate on ontogenetic behavior of bastard halibut, Paralichthys olivaceus (T. et S.)

The effects of temperature and substrate on ontogenetic patterns and settlement behavior of bastard halibut, Paralichthys olivaceus (T. et S.) were studied in a series of laboratory experiments. Analysis on stage-based data revealed that except for settlement, and compared to the substrate, the ambient temperature dominantly controlled the hatch success and subsequent development of the species. The oosperm optimum s...  (本文共7页) 阅读全文>>

Identification of candidate piRNAs in the gonads of Paralichthys olivaceus (Japanese flounder)

Piwi-interacting RNA(piR NA) plays an important role in the gonadal development and maintenance of Teleostei. In this study, pi RNA libraries derived from the adult gonads of Japanese flounder(Paralichthys olivaceus) were generated using next-generation sequencing technology. Using zebrafish piR NAs as a reference, 5 865 unique candidate...  (本文共6页) 阅读全文>>
