7Production of Pacific White Shrimp Polycultured with Swimming Crab at Different Densities, and Nutrient Budget in the Enclosure System显示文摘This study was to evaluate the effect of stocking densities on the nitrogen and phosphorus budgets for a polyculture of the crab Portunus trituberculatus and the Pacific white shrimp Litopenaeus vannamei.The shrimps(initial weight,0.012 g)were cultured at a density of 45 shrimp m^(-2),and juvenile crabs(initial weight,0.024 g)were cultured at five densities of 0,3,6,9,and 12 crabs m^(-2).The treatments were grouped as C0S45,C3S45,C6S45,C9S45,and C12S45,respectively.Water quality parameters,growth of shrimp and crabs,and nitrogen and phosphorus budget were measured.The results indicated that the shrimp performances in polyculture treatments C3S45 and C6S45 were superior to those in the crab-free treatment(C0S45).The crab in treatments C3S45 and C6S45 exhibited a significantly higher final mean weight and carapace width/length than those in treatments C9S45 and C12S45.The final size and survival of crabs had a negative correlation with the increasing crab stocking density.The contents of total phos-phorus and total nitrogen and the comprehensive contamination index values were higher in the C9S45 and C12S45 treatments than in the other treatments.The conversion ratios of nitrogen for crab and shrimp growth in treatment C3S45 were significantly higher than those in the crab-free treatment.These findings indicate that polyculturing shrimp with crabs at suitable densities can improve productivity,profitability,nutrient utilization,and the environmental quality.From the 60-day treatments,the optimal culture densi-ties were 3-6 crabs m^(-2) and 45 shrimps m^(-2).ZHOU Yangen BAO Weiyang SU Yuepeng HUANG Ming WANG Xingqiang YAN Binlun MA Shen 2022Journal of Ocean University of China2022,21,1:0
8Growth,serum biochemical parameters,salinity tolerance and antioxidant enzyme activity of rainbow trout(Oncorhynchus mykiss)in response to dietary taurine levels显示文摘This study evaluated the effect of dietary taurine levels on growth,serum biochemical parameters,salinity adaptability,and antioxidant activity of rainbow trout(Oncorhynchus mykiss).Four diets were formulated with taurine supplements at 0,0.5,1,and 2%w/v(abbreviated as To,T05,Tt,and T2,respectively).Rainbow trouts(initial weight of 80.09±4.72 g)were stocked in tanks(180 L capacity),and were fed these diets for six weeks and subsequently underwent salinity acclimation.Physiological indicators were determined before salinity acclimation at 1,4,7,and 14 days afterwards.Results showed that there were no significant differences in growth performance(final mean weight ranged from 182.35 g to 198.48 g;percent weight gain was between 127.68%and 147.92%)of rainbow trout in freshwater stage,but dietary taurine supplement significantly increased serum-free taurine content.After entering seawater,the Na+-K+-ATPase activity of T2 group returned to its freshwater levels,and the serum cortisol content was significantly higher than To and To 5 groups.At the end of this experiment,the liver superoxide dismutase activity in the To and To 5 groups was significantly lower than in the Tj and T2 groups,and the liver catalase in the To group was the lowest whereas that in the T2 group was the highest.Muscle malondialdehyde content was the highest in the To group,and the lowest in the T2 group.Based on the results of this study,supplement of dietary taurine(0.5-2%)enhanced the salinity tolerance in rainbow trout,which increased with the higher taurine concentration.Ming Huang Xiaogang Yang Yangen Zhou Jian Ge DAllen Davis Yunwei Dong Qinfeng Gao Shuanglin Dong 2021Marine Life Science & Technology2021,3,4:0
9Iron-catalyzed cyanoalkylation of difluoroenol silyl ethers with cyclobutanone oxime esters显示文摘An iron-catalyzed coupling reaction of difluoroenol silyl ethers and cyclobutanone oxime esters is described. This protocol provides a convenient access to various previously unknown and potentially useful gem-difluoromethylenated ketonitriles inmoderate to good yields. The transformations of resulting products to other fluorinecontaining products is also documented.Xiaolei Zhu Yangen Huang Xiuhua Xu Fengling Qing 2022Chinese Chemical Letters2022,33,2:0
10Fatty Acid Composition and Digestive Enzyme Activities of Rainbow Trout in Response to Dietary Docosahexaenoic Acid(DHA)and Eicosapentaenoic Acid(EPA)During Salinity Acclimation显示文摘This physiological study aimed to evaluate the effects of dietary docosahexaenoic acid(DHA)and eicosapentaenoic acid(EPA)on the fatty acid composition and digestive enzyme activities of rainbow trout(Oncorhynchus mykiss)during salinity acclimation.Rainbow trout with an average initial weight of 90.61 g±9.25 g were fed diets with the quantities of DHA and EPA equaling to 0.54%,0.95%,1.40%and 1.79%(abbreviated as DE-0.54,DE-0.95,DE-1.40,and DE-1.79,respectively)for eight weeks,after which the gastric and intestinal fatty acids composition were analyzed.Subsequently,the fish underwent salinity acclimation.On days 1,4,7,and 14 after the freshwater was replaced by seawater and at the end of the 8-week period,gastric and intestinal digestive enzyme activities were determined.The results showed that the gastric and intestinal DHA and EPA contents of the fish were positively correlated to their dietary DHA and EPA levels.Low dietary DHA and EPA levels inhibited the protease activity of rainbow trout.Fish in the DE-0.54 group increased the lipase activity to enhance the utilization of lipids maybe due to the inadequate essential fatty acids for fish in this group.Hence,rainbow trout in the DE-0.54 group failed to maintain suitable activities of digestive enzymes after salinity acclimation.Therefore,a diet with minimum 0.95%DHA and EPA levels is necessary for rainbow trout during salinity acclimation.HUANG Ming ZHOU Yangen GE Jian AGUSTSSON Thorleifur LI Li GAO Qinfeng DONG Shuanglin 2020Journal of Ocean University of China2020,19,6:0
11Facile syntheses of 3-trifluoromethylthio substituted thioflavones and benzothiophenes via the radical cyclization显示文摘3-CF3 S substituted thioflavones and benzothiophenes were achieved via the reactions of AgSCF3 with methylthiolated alkynones and alkynylthioanisoles,respectively,promoted by persulfate.This protocol possesses good functional group tolerance and high yields.Mechanistic studies suggested that a classic two-step radical process was involved,which includes addition of CF3 S radical to triple bond and cyclization with SMe moiety.Lu Wang Huaiyu Wang Weidong Meng Xiu-Hua Xu Yangen Huang 2021Chinese Chemical Letters2021,32,1:0
