| 1 | The Effect of Netting Solidity Ratio and Inclined Angle on the Hydrodynamic Characteristics of Knotless Polyethylene Netting显示文摘Knotless polyethylene(PE) netting has been widely used in aquaculture cages and fishing gears, especially in Japan. In this study, the hydrodynamic coefficient of six knotless PE netting panels with different solidity ratios were assessed in a flume tank under various attack angles of netting from 0?(parallel to flow) to 90?(perpendicular to flow) and current speeds from 40 cm s^(-1) to 130 cm s^(-1). It was found that the drag coefficient was related to Reynolds number, solidity ratio and attack angle of netting. The solidity ratio was positively related with drag coefficient for netting panel perpendicular to flow, whereas when setting the netting panel parallel to the flow the opposite result was obtained. For netting panels placed at an angle to the flow, the lift coefficient reached the maximum at an attack angle of 50? and then decreased as the attack angle further increased. The solidity ratio had a dual influence on drag coefficient of inclined netting panels. Compared to result in the literature, the normal drag coefficient of knotless PE netting measured in this study is larger than that of nylon netting or Dyneema netting. | TANG Hao HU Fuxiang XU Liuxiong DONG Shuchuang ZHOU Cheng WANG Xuefang | 2017 | Journal of Ocean University of China2017，16，5： | 4 |
| 2 | Comparison of nominal and standardized catch per unit effort data in quantifying habitat suitability of skipjack tuna in the equatorial Pacific Ocean显示文摘In the western and central Pacific Ocean,upper strata waters exhibit highly dynamic oceanographic features under ENSO variability.This has been proved to be responsible for the dynamic change of both abundance and zonal distribution of skipjack tuna(Katsuwonus pelamis).Although causality has been suggested by researchers using physical-biological interaction models,cumulative evidence needs to be obtained and the tenability of assertion needs to be tested from an ecological habitat perspective,based on fisheries data.For purse seine fishery,the use of catch per unit effort(CPUE)as an indication of the abundance is confusing because of technical improvements over the whole exploitation history and unbalanced individual fishing characteristic of vessels.It is particularly interesting to discriminate between habitat characteristics in comparative scenarios of CPUE application.This study identified habitat traits based on a series of oceanographic factors from a global ocean reanalysis model.A comparison was conducted between two habitat models based on unprocessed purse seine CPUE and standardized CPUE considering fishing characteristics.The results suggest that standardized CPUE could model the regular zonal shift of habitat compatible with the observed fishing efforts transfer,and achieved better prediction capacity than unprocessed CPUE.Furthermore,the habitat of skipjack tuna was also characterized and linked with surface and subsurface thermal environment,ocean current,dissolved oxygen,biotic environment,and ENSO variability.The monthly-averaged habitat suitable index,derived from the optimal habitat model prediction,showed a significant linear relationship with the southern oscillation index,which suggested that El Ni?o episodes eventually provide more preferable habitat for skipjack tuna under ENSO variability. | Cheng Zhou Yuanyuan Hu Jie Cao Liuxiong Xu Xuefang Wang Rong Wan Yu Xiao Jiangfeng Zhu Hao Tang | 2022 | Acta Oceanologica Sinica2022，41，3： | 3 |
| 3 | Investigation on the photo-induced de-oxygenation process of myoglobin in aqueous solution by use of fluorescence spectroscopy显示文摘A photo-induced de-oxygenation process of myoglobin (Mb) in aqueous solution was investigated by use of fluorescence spectroscopy. The spectra are characterized by the fluorescence intensity declining gradually after each scan,and the decay of fluorescence intensity being significant in each scan,which is assigned to the release of oxygen from the opening of the heme-pockets induced by illumination. More illumination will cause more release of oxygen; if the temperature of an Mb solution is increased when it is illuminated,the rate of de-oxygenation will be higher. It was found that ligand-oxygen in Fe-porphyrin could be removed from Mb by nitrogen. This indicates that the interac-tion between oxy-Mb and other different gases can be tested by the method of fluorescence spectros-copy. In addition,fluorescence spectroscopy can be employed to probe the energy transfer between Fe-porphyrin and tryptophan or tyrosine in Mb molecules. | MA JunYan ZHENG XueFang TANG Qian MA Jing GAO DaBin HU JiHan | 2008 | Science China Chemistry2008，51，5： | 2 |
| 4 | Vegetation and Soil Characteristics of Different Desertification Grasslands in Northwest Sichuan显示文摘[Objective]The paper was to study vegetation and soil characteristics of different desertification grasslands in northwest Sichuan. [Method]By taking different desertification grasslands as the research object,the characteristic factors of vegetation community,biomass,soil moisture content,volume weight and porosity were analyzed through scientific investigation,sampling and formula calculation to reveal the changes in vegetation and soil characteristics of different desertification grasslands in Northwest Sichuan. [Result]Community succession presented the pattern of ' hygrophyte-mesophyte-xerophyte' with the aggravation of grassland desertification. The height and coverage of community decreased,species richness was declined by 88%,and composition of dominant species also changed greatly. The diversity index of light-desertification grassland was the highest among tested grasslands. Total biomass was decreased by 90. 4%,and the underground biomass decreased far more than aboveground biomass. In desertification progress,both soil moisture content and water holding capacity decreased,while volume weight showed upward trend and porosity showed downward trend; soil characteristics had large variation in early stage of desertification,so restoration treatment of desertification grassland should be carried out in the early stage of desertification. [Conclusion]The study provided a theoretical basis for researches on causes and management programs of desertification grassland,having an important meaning for ecological restoration of regional grassland and maintenance of ecological security. | Wan Ting Tu Weiguo Xi Huan Li Yudong Tang Xuefang Yang Yichuan | 2014 | Animal Husbandry and Feed Science2014，6，2： | 1 |
| 5 | Degradability evaluation for natural material fibre used on fish aggregation devices(FADs)in tuna purse seine fishery显示文摘Purse seiners deploy large amounts of drifting fish aggregation devices(FADs)in all tropical oceans to catch tunas.These FADs are constructed with porous synthetic fibre netting,which are responsible for incidental mortality of sea turtles and sharks through entanglement,and can engage in ghost fishing if they are lost and abandoned.The use of natural or biodegradable materials to build FADs can effectively mitigate marine pollution and bycatch issues,and as such they are currently promoted by fisheries management organizations.This study evaluated the degradability of ropes made of common natural fibres;cotton rope(3-strand,96-thread,twisted,S-lay),jute rope(3-strand,13-thread,twisted,Z-lay)and sisal rope(3-strand,8-thread,twisted,Z-lay).Degradability was evaluated by measuring the breaking strength(cN/dtex)and retention ratio of rupture elongation.Results showed that jute rope and sisal rope experienced rapid reduction of strength which over the first month soaking in the sea fell by 66.8%and 46.9%,respectively.Cotton rope exhibited the most inert degradation behavior,with breaking strength maintained at half of the initial value at 10 months.The retention ratio of rupture elongation for jute ropes and sisal ropes fluctuated considerably in the following months after deployment,compared to the relatively stable change for cotton rope.Results suggested that among these congeners,cotton rope would be most preferable component for Bio-FADs with a 10-month minimum durability that matches the required lifetime of FAD fishing strategies. | Yucheng Wang Cheng Zhou Liuxiong Xu Rong Wan Jiangao Shi Xuefang Wang Hao Tang Lumin Wang Wenwen Yu Kai Wang | 2021 | Aquaculture and Fisheries2021，6，4： | 1 |

| 8 | Diversity and independent evolutionary profiling of rodent-borne viruses in Hainan,a tropical island of China显示文摘The risk of emerging infectious diseases(EID)is increasing globally.More than 60%of EIDs worldwide are caused by animal-borne pathogens.This study aimed to characterize the virome,analyze the phylogenetic evolution,and determine the diversity of rodent-borne viruses in Hainan Province,China.We collected 682 anal and throat samples from rodents,combined them into 28 pools according to their species and location,and processed them for next-generation sequencing and bioinformatics analysis.The diverse viral contigs closely related to mammals were assigned to 22 viral families.Molecular clues of the important rodent-borne viruses were further identified by polymerase chain reaction for phylogenetic analysis and annotation of genetic characteristics such as arenavirus,coronavirus,astrovirus,pestivirus,parvovirus,and papillomavirus.We identified pestivirus and bocavirus in Leopoldoms edwardsi from Huangjinjiaoling,and bocavirus in Rattus andamanensis from the national nature reserves of Bangxi with low amino acid identity to known pathogens are proposed as the novel species,and their rodent hosts have not been previously reported to carry these viruses.These results expand our knowledge of viral classification and host range and suggest that there are highly diverse,undiscovered viruses that have evolved independently in their unique wildlife hosts in inaccessible areas. | Youyou Li Chuanning Tang Yun Zhang Zihan Li Gaoyu Wang Ruoyan Peng Yi Huang Xiaoyuan Hu Henan Xin Boxuan Feng Xuefang Cao Yongpeng He Tonglei Guo Yijun He Haoxiang Su Xiuji Cui Lina Niu Zhiqiang Wu Jian Yang Fan Yang Gang Lu Lei Gao Qi Jin Meifang Xiao Feifei Yin Jiang Du | 2023 | Virologica Sinica2023，38，5： | 0 |
