| 1 | Growth and Mortality of Small Yellow Croaker(Larimichthys polyactis) Inhabiting Haizhou Bay of China显示文摘Length frequency data of small yellow croaker(Larimichthys polyactis) were acquired from the survey vessel in May,July,September and December,2011 in Haizhou Bay of China.In this study,921 fish individuals were analyzed for the estimation of growth and mortality parameters.Between length and weight,the power coefficient b was 2.7321,2.9703,3.0418 and 2.7252 for the 4 surveying months,respectively.The estimated von Bertalanffy growth function parameters were 230mm(L ∞) and 0.26yr-1(K) as were calculated with ELEFAN method equipped in FiSAT computer package.With length-converted catch curve analysis,the total mortality rate(Z) and its 95% confidence interval were 2.16(1.69-2.64) yr-1,0.59(0.15-1.04) yr-1,1.16(0.80-1.52) yr-1 and 0.96(0.70-1.23) yr-1 for the 4 surveying months,respectively,with the pooled data the value was 1.15(0.81-1.48) yr-1.The natural mortality rate(M) was 0.516 yr-1 as was calculated with Pauly's equation(the annual average sea water temperature was 11℃).Therefore,fish mortality rate was 0.634 yr-1.The yield-per-recruit analysis indicated that when t c was 1,F max was 0.7 and F 0.1 was 0.55.Currently,the age at first capture is about 1 year and F current was 0.634.Therefore,F current was larger than F 0.1 and less than F max.This indicates that current fish mortality is at a dangerously high level.With Gulland method,the biological reference point for fishery(F opt) was estimated as 0.516 yr-1,lower than current fish mortality.Accordingly,reducing catch in the region was strongly recommended. | LIU Qun XU Binduo YE Zhenjiang REN Yiping | 2012 | Journal of Ocean University of China2012，11，4： | 17 |
| 2 | Spatial and Seasonal Patterns of Ichthyoplankton Assemblages in the Haizhou Bay and Its Adjacent Waters of China显示文摘Surveys were conducted in five voyages in Haizhou Bay and its adjacent coastal area from March to December 2011 during full moon spring tides. The ichthyoplankton assemblages and the environmental factors that affect their spatial and seasonal patterns were determined. Totally 35 and 12 fish egg and larvae taxa were identified, respectively. Over the past several decades, the egg and larval species composition has significantly changed in Haizhou Bay and its adjacent waters, most likely corresponding with the alteration of fishery resources, which are strongly affected by anthropogenic activities and climate change. The Bray-Curtis dissimilarity index identified four assemblages: near-shore bay assemblage, middle bay assemblage and two closely related assemblages(near-shore/middle bay assemblage and middle/edge of bay assemblage). The primary species of each assemblage principally reflected the spawning strategies of adult fish. The near-shore bay assemblage generally occurred in near-shore bay, with depths measuring <20 m, and the middle bay assemblage generally occurred in the middle of bay, with depths measuring 20 to 40 m. Spatial and seasonal variations in ichthyoplankton in each assemblage were determined by interactions between biological behavioral traits and oceanographic features, particularly the variation of local conditions within the constraint of a general reproductive strategy. The results of Spearman's rank correlation analysis indicated that both fish egg and larval abundance were positively correlated with depth, which is critical to the oceanographic features in Haizhou Bay. | LI Zengguang YE Zhenjiang WAN Rong | 2015 | Journal of Ocean University of China2015，14，6： | 10 |
| 3 | Analyses of egg size,otolith shape,and growth revealed two components of small yellow croaker in Haizhou Bay spawning stock显示文摘The geographical variations in life history characteristics of small yellow croaker Larimichthys polyactis, caused by experienced different environmental conditions, have been observed in China seas. Previous studies based on spatial distribution, migration route, and body morphometrics suggested a complex stock structure. In this study, to clarify the source of a spawning stock, we investigated the reproduction strategy and inter-structure of the Haizhou Bay (HZB) spawning stock in the middle Yellow Sea from both egg survey and adult otolith increment analysis. Egg and adult samples were collected from three surveys during spawning season in 2013. Distinct spatial and temporal variations were detected in egg distribution and size, and otolith shape analysis of adult fishes revealed two morphotypes with different increment growth using random forest cluster. The results indicate the existence of two components within the same spawning stock in HZB from different wintering grounds, and accordingly special protection should be required for this stock given the significance to maintain connectivity between adjacent subpopulations. | JIANG Yiqian ZHANG Chi YE Zhenjiang TIAN Yongjun | 2019 | Journal of Oceanology and Limnology2019，37，4： | 3 |
| 4 | Identification of five Pampus species from the coast of China based on sagittal otolith morphology analysis显示文摘Sagittal otoliths morphology were compared to identify five Pampus species of the Chinese coast(Chinese pomfret Pampus chinensis, grey pomfret P. cinereus, southern lesser pomfret P. minor, plumage pomfret P.punctatissmus, and Pampus sp.). Otoliths demonstrated species-specific characteristics with noticeable differences in overall shape, margin and anterior region among species. With species divergence, otoliths get thinner following further developed rostrum and anti-rostrum. Interspecies variation in otolith could associate with experienced different temperature and water column. The discriminant analysis presented a high classification accuracy of 96.6%, which confirms the inter-specific distinction of otolith shape and enable the species identification. | ZHANG Chi FAN Yannan YE Zhenjiang LI Zengguang YU Hongliang | 2017 | Acta Oceanologica Sinica2017，36，2： | 3 |
| 5 | Use of Otolith Shape for the Identification of Trumpeter Sillago (Sillago maculata) and Silver Sillago(Sillago sihama)显示文摘Otolith shape is species-specific in fish.In this study,161 samples of Trumpeter sillago Sillago maculata and 164 of Silver sillago Sillago sihama were collected from Beibu Gulf in July 2009.The main objective of this study was to use morphological variables and Fourier harmonics to describe otolith characteristics and use discriminant analyses to separate the two species.Otoliths were measured by traditional one and two dimensional measures(otolith length,width,diameters,area,perimeter,rectangularity and circularity),as well as by Fourier analysis to capture the finer regions of the otolith.Analysis of covariance(ANCOVA) showed that there was significant correlation between morphological variables(diameter,perimeter,otolith length,otolith width,otolith area,density,harmonics 3,harmonics 4,harmonics 5,harmonics 13,harmonics 15,and harmonics 16) and body length.To minimize size effects on the morphological variables between species,only fish with a body length between 90 and 140 mm were included in the data analysis and the variables which had significant relation with body length were transformed using the residual.The result showed that the accuracy of discriminant analysis was 97.8% and 100% for Trumpeter sillago and Silver sillago,respectively.This high accuracy indicated that otolith shape was described accurately by morphological variables and Fourier harmonics,and discriminant analysis was an effective way to identify and separate the two species. | WANG Yingjun YE Zhenjiang LIU Qun | 2010 | Journal of Ocean University of China2010，9，3： | 2 |
| 6 | Spatial and temporal characteristics of trophic structure of the southern Huanghai Sea fish communities显示文摘The spatial and temporal characteristics of trophic structure of fish communities in the southern Huanghai Sea were examined based on the data sampled from bottom trawl surveys conducted during the autumn of 2000 and the spring of 2001.Hierarchical agglomerative cluster method and bootstrap randomization were used to identify significant trophic groups for each fish assemblage in the southern Huanghai Sea.A total of six major trophic groups were identified within this system,which classified predators based upon location in the water column or prey size(i.e.,benthic to pelagic predators or fish to small invertebrate prey predators).The similarity level used to identify significant trophic groups in each assemblage ranged from 24% to 34%.Although planktivores were the dominant trophic group in each assemblage(60%~79%),there were spatial and temporal variations in the trophic structure,which reflected the differences in the abundance and availability of dominant preys.Simplified food webs were constructed to evaluate the most important trophic relationships between the dominant prey taxa and the fishes in each assemblage within this system.Although there were some differences in the key prey species among different food webs,pelagic prey items(mainly euphausiids and copepods)represent the most important energetic link between primary producers and higher trophic level predators.The trophic level for most fishes was between 3 and 4,and the weighted mean trophic level for each assemblage ranged from 3.3 to 3.4.Compared with previous study in the mid-1980s,there was an obvious downward trend in the trophic level for most fish species,which resulted mainly from the fluctuation in key prey species in the Huanghai Sea.The decrease in the importance of Japanese anchovy seems to be offset by other abundant prey species such as Euphausia pacifica and copepods(mainly Calanus sinicus). | XUE Ying JIN Xianshi LIANG Zhenlin YE Zhenjiang | 2008 | Acta Oceanologica Sinica2008，27，4： | 2 |
| 7 | Android Apps:Static Analysis Based on Permission Classification显示文摘Android has a strict permission management mechanism. Any applications that try to run on the Android system need to obtain permission. In this paper, we propose an efficient method of detecting malicious applications in the Android system. First, hundreds of permissions are classified into different groups. The application programming interfaces (APIs) associated with permissions that can interact with the outside environment are called sink functions. The APIs associated with other permissions are called taint functions. e construct association tables for block variables and function variables of each application. Malicious applications can then be detected by using the static taint-propagation method to analyze these tables. | Zhenjiang Dong Hui Ye Yan Wu Shaoyin Cheng Fan Jiang | 2013 | ZTE Communications2013，11，1： | 2 |

| 9 | Study on Laser Transformation Hardening of HT250 by High Speed Axis Flow CO_2 Laser显示文摘In this article, laser transformation hardening of HT250 material by high speed axis flow CO2 laser was investigated for first time in China. Appropriate laser hardening parameters, such as laser energy power P(W), laser scanning rate V(m/min),were optimized through a number of experiments. The effect of the mentioned parameters on the hardened zone, including its case depth, microhardness distributions etc., were analyzed. Through the factual experiments, it is proved that axial flow CO2 laser, which commonly outputs low mode laser beam, can also treat materials as long as the treating parameters used are rational. During the experiments, the surface qualities of some specimens treated by some parameters were found to be enhanced, which does not coincide with the former results. Furthermore in the article, the abnormal phenomenon observed in the experiments is discussed. According to the experimental results, the relationship between laser power density q and scanning rate V is shown in a curve and the corresponding formulation, which have been proved to be valuable for choosing the parameters of laser transformation hardening by axial flow CO2 lasers, was also given. | Yunxia YE, Yonghong FU and Yongkang ZHANGMechanical Engineering College, Jiangsu University, Zhenjiang 212013, China | 2003 | Journal of Materials Science & Technology2003，19，2： | 1 |
| 10 | Incorporating mesopelagic fish into the evaluation of conservation areas for marine living resources under climate change scenarios显示文摘Mesopelagic fish(meso-fish)are central species within the Southern Ocean(SO).However,their ecosystem role and adaptive capacity to climate change are rarely integrated into protected areas assessments.This is a pity given their importance as crucial prey and predators in food webs,coupled with the impacts of climate change.Here,we estimate the habitat distribution of nine meso-fish using an ensemble model approach(MAXENT,random forest,and boosted regression tree).Four climate model simulations were used to project their distribution under two representative concentration pathways(RCP4.5 and RCP8.5)for short-term(2006–2055)and long-term(2050–2099)periods.In addition,we assess the ecological representativeness of protected areas under climate change scenarios using meso-fish as indicator species.Our models show that all species shift poleward in the future.Lanternfishes(family Myctophidae)are predicted to migrate poleward more than other families(Paralepididae,Nototheniidae,Bathylagidae,and Gonostomatidae).In comparison,lanternfishes were projected to increase habitat area in the eastern SO but lose area in the western SO;the opposite was projected for species in other families.Important areas(IAs)of meso-fish are mainly distributed near the Antarctic Peninsula and East Antarctica.Negotiated protected area cover 23% of IAs at present and 38%of IAs in the future(RCP8.5,long-term future).Many IAs of meso-fish still need to be included in protected areas,such as the Prydz Bay and the seas around the Antarctic Peninsula.Our results provide a framework for evaluating protected areas incorporating climate change adaptation strategies for protected areas management. | Shuhao Liu Yang Liu Katharina Teschke Mark AHindell Rachel Downey Briannyn Woods Bin Kang Shuyang Ma Chi Zhang Jianchao Li Zhenjiang Ye Peng Sun Jianfeng He Yongjun Tian | 2024 | Marine Life Science & Technology2024，6，1： | 0 |
| 11 | Inter-Annual Variabilities of the Body Weights of Two Cephalopod Species in the Yellow Sea Under Different Environmental Conditions显示文摘As fish stocks have been overexploited and catches have decreased over the last few years,the cephalopod catch has increased globally to the point that they are now among the most important marine resources in the world.Climate change and hu-man activities greatly affect the growth and abundance of cephalopods.Understanding how the individual growth of key species varies and how they respond to environmental changes is essential for an effective fishery management.Loliolus beka and Amphioc-topus fangsiao are two dominant species in the cephalopod community of Yellow Sea(YS).Both of them are commercially impor-tant and have great ecological values.Herein,we compared the body weights(BW)of these two species from 2011 to 2018 based on an analysis of biological parameters(i.e.,mantle length and BW)from trawl surveys in the YS.Considerable temporal variations in the BW of the two species are apparent.Specifically,the BW of L.beka was the lowest in 2011 and the highest in 2017,and the well growth was noted in 2015-2018.The BW of A.fangsiao was the lowest in 2013 and the highest in 2016,while well growth was ob-served in 2015-2016.Mixed-effect models indicate that the BW of these species correlates significantly with the sea surface tem-perature(SST)and Southern Oscillation Index(SOI),suggesting the impact of the regional environment associated with strong ENSO events on BW.In a different response window,growth increases with increased SST and decreases with increased SOI.The consistent patterns of the BW of these cephalopods in response to environmental factors demonstrate they can be employed as indi-cator species for studying environmental change in the YS.Our results improve the understanding of the responses of cephalopods to environmental changes in the YS,as well as the mechanisms that drive their growth.Such information is critical for the effective management and sustainable development of cephalopod fisheries in this region. | GUO Jianzhong ZHANG Chi LI Jianchao TIAN Yongjun YE Zhenjiang LI Zhixin GAO Zihui | 2022 | Journal of Ocean University of China2022，21，2： | 0 |
| 12 | Stock Structure Analysis of the Japanese Spanish Mackerel Scomberomorus niphonius(Cuvier, 1832) Along the China Coast Based on Truss Network显示文摘The Japanese Spanish mackerel Scomberomorus niphonius(Cuvier,1832)is widely distributed in the subtropical and temperate waters of the northwestern Pacific Ocean,supporting one of the most important commercial fisheries in China.However,ignoring the potential population structure changes induced by fishing pressure and climate change may undermine the population stability under the current management strategy.In this study,the population structure of the Japanese Spanish mackerel was investigated based on a morphometric truss network system.A total of 534 individuals were randomly collected from commercial gill nets spanning eight major spawning grounds in the Bohai,Yellow,and East China Seas during the peak spawning seasons respectively.A total of 17 measurements(including eye diameter)were conducted in each specimen and subjected to principal component analysis(PCA)and discriminant function analysis(DFA).The results of PCA indicated that the first two factors cumulatively caused 78.38%of the total morphometric variation and observable differences,primarily fin the caudal and trunk areas.The results of DFA revealed that the eight spawning groups can be divided into three stocks,i.e.,southern,middle,and northern stocks,with 68.7%of total accuracy.In contrast to previous studies,the spawning groups of the Japanese Spanish mackerel demonstrated a tendency to disperse to northern regions.In conclusion,this study found that to maintain the stability of the population structure and the total production of Japanese Spanish mackerel S.niphonius(Cuvier,1832),a newly revised management method should be developed and implemented. | JIANG Yiqian ZHANG Chi YE Zhenjiang XU Binduo TIAN Yongjun WATANABE Yoshiro | 2020 | Journal of Ocean University of China2020，19，2： | 0 |

| 14 | Functional groups and seasonal diversity of crustacean zooplankton in adjacent waters of Haizhou Bay,South Yellow Sea显示文摘Zooplankton are important linkages in the food web and can respond nonlinearly to environmental changes.Marine organisms thrive from spring to summer.Thus,it is crucial to understand how ecological functions of zooplankton communities may shift under seasonal environmental changes during this period.Samples were collected from May to August(May,June-Ⅰ,June-Ⅱ,July-Ⅰ,July-Ⅱ,and August)in 2018 in Haizhou Bay,Jiangsu,East China for zooplankton and environmental variables.Crustaceans accounted for 75 out of 134 zooplankton taxa and 91.8%of total zooplankton abundance.The average abundance of crustacean varied between 2824.6±635.4 inds./m3 in July-Ⅱand 6502.7±1008.8 inds./m3 in June-Ⅱ.Multivariate analyses results showed that the dissimilarity of community increased gradually in the time series.Body length,feeding type,trophic group,and reproduction mode were used to investigate crustacean community functions.Trait-based functional groups contained species with similar ecological roles.Functional diversity fused the differences of species and trait.The proportion of large-sized species(2-5 mm)decreased with the increasing proportion of medium-sized species(1-2 mm).The proportion of current feeders increased with the drop in the proportion of mixed feeders.Parthenogenesis species increased with decreasing free spawners,and omnivores-carnivores increased with decreasing omnivoresherbivores.Generalized additive models suggested that temperature was the main driver of variations in crustacean zooplankton function.Seven identified functional groups varied with increasing temperature.Omnivorous-herbivorous copepods declined(90.0%-68.0%),whereas the parthenogenetic cladocerans increased(0-24.1%).The small egg-brooding ambush copepods fluctuated(6.5%-9.3%)with increasing water temperature.The other functional groups changed slightly.Functional diversity also varied according to temperature changes.The community structure and ecological function of crustacean zooplankton community showed gradual changes with increasing temperature from spring to summer. | Zeqi ZHENG Shunan FU Yixuan LI Ruping GE Hongju CHEN Zhenjiang YE Yunyun ZHUANG Guangxing LIU | 2023 | Journal of Oceanology and Limnology2023，41，3： | 0 |
| 15 | Community structure of mesopelagic fauna and the length-weight relationships of three common fishes in the Cosmonaut Sea,Southern Ocean显示文摘This study used specimens of marine organisms caught by rectangular midwater trawl in the Cosmonaut Sea,Southern Ocean,in austral summer 2019/2020,to determine species composition and spatial distributions of mesopelagic fauna in this sea.The data were also used to calculate the length-weight relationships of three common fishes captured during the survey(Electrona antarctica,Bathylagus antarcticus,and Cyclothone microdon).A total of 385 individual organisms with a total weight of 15462.2 g and representing 17 species were collected across the 11 stations visited.The small-sized crown jellyfish Atolla wyvillei(order Coronatae)was the most-dominant species by number(96 individuals),and the zooplankton Cyllopus lucasii(Amphipoda)also showed high abundance(54 individuals).Among fishes,81 individuals of Notolepis coatsorum(Paralepididae)were caught,followed by 71 individuals of E.antarctica(Myctophidae),25 individuals of B.antarcticus(Bathylagidae),and 16 individuals of C.microdon(Gonostomatidae).Clustering analysis divided the mesopelagic community into“west”and“east”groups,and a greater number of individuals were collected in the western part of the sea.The length-weight relationships of the three common fishes revealed positive allometric growth for B.antarcticus(b=3.16),and negative allometric growth for E.antarctica and C.microdon(both b=2.53).Our descriptions of the mesopelagic-zone community structure and biological features of three common fishes provide basic information on the ecology of the Cosmonaut Sea,Southern Ocean,and will be useful for ecosystem-based fisheries management in this region. | WANG Yehui LIU Chunlin DUAN Mi ZHANG Chi YE Zhenjiang LIU Yang TIAN Yongjun HE Jianfeng | 2022 | Advances in Polar Science2022，33，2： | 0 |
| 16 | Age, growth, reproductive biology, color pattern, and ontogenetic divergence of two closely related rock?shes (Sebastes koreanus and S. nudus) off the coasts of the Shandong Peninsula, China显示文摘The live-bearing genus Sebastes is renowned for its outstanding species richness and color diversity,and its speciation has been a point of interest.This study investigated the age,growth,reproductive biology,color pattern and ontogenetic divergence of a pair of closely related rockfishes from the coasts of the Shandong Peninsula,namely,Sebastes koreanus(n=879)and S.nudus(n=257).Marginal increment analysis of sectioned otoliths showed that annulus formation occurred once a year between June and July in both species.The sex-pooled growth curves of S.nudus and 3 populations of S.koreanus differed significantly from each other.No apparent latitudinal cline in growth parameters was found in S.koreanus.For both species,the peak parturition periods were from April to May,and the peak copulation periods were from November to December.S.nudus has a highly variable and conspicuous color pattern while S.koreanus has a stable and dull color pattem.This difference,together with the overlapping distribution and the close relationship,make S.koreanus and S.nudus an ideal model to investigate the color-driven speciation of the Sebastes.We confirmed that S.nudus changes its body color with age and season and fully expresses the carotenoid-based nuptial coloration when the fish reaches first maturity.Moreover,our comparisons of morphological traits that are likely related to survival and quality of these fishes suggested that S.nudus may suffer higher predation risk and foraging difficulty beginning at age 3.In light of the ontogenetic development of the color pattern in S.nudus,we suggested that the full expression of nuptial coloration most likely triggers the strong selective pressure to enhance swimming performance,anti-predator defense and foraging capacity of S.nudus through predator-prey interactions.By understanding all these details,we further inferred a hypothesis that both color pattem and bathymetric segregation play key roles in facilitating the speciation of demersal rockfishes. | ZHUANG Longchuan ZHANG Chi LIU Qun YE Zhenjiang | 2020 | Journal of Oceanology and Limnology2020，38，1： | 0 |
| 17 | IMS and Converged Service Network显示文摘The current telecom target network architecture with IP Multimedia Subsystem (IMS) as the core lacks the actual verification of existing large-scale networks and faces the stiff competition from Internet technologies. In the process of promoting the commercial usage of IMS services, the Service Delivery Platform (SDP) is evolving into a more convergent and open Service Delivery Environment (SDE) and will become the mainstream of the next generation Telecom Service Network. ZTE's concept of the Converged Service Network (CSN) is to integrate various network service capabilities to realize the unification of data, service, capability and management and thus the fast provisioning of various Value-Added Services (VASs), which helps the carriers to maintain a leading position in the value chain, meeting the telecom carriers ' requirements for service network development. | Ye Yun, Dong Zhenjiang (ZTE Corporation, Shenzhen 518057, P.
