| 1 | Preliminary Evaluation on Resources Enhancement of Artificial Reef in the East Corner of Zhelang Shanwei显示文摘In order to analyze the improvement of fish resource,the trawl net and gill net were used in the background survey and investigation in the artificial reef area and control area of the east of corner was discussed in Zhelang Shanwei in January 2003 and April 2010 respectively.Margalef species richness index,Shannon-Winener diversity index and Pileou uniformity index were chosen to analyze the multiformity of biological population and community structure.Resource density index of trawl net investigation and catch rate of gill net were chosen to estimate the variance of biomass.The results of the trawl net showed that the resources density of the artificial area increased by 3.078 times,and numbers of species increased by 1.875 times,squilla being the dominant group instead of the fish,and the first dominant species being squilla oratoria(Oratosquilla oratoria),which increased by 4.372 times before the artificial reef dropped.The results of the gill net showed that the catch rate of the artificial area increased by 12.043 times,numbers of species increased by 1.333 times,the dominant group was fish,it increased greatly,the first dominant species was golden small fish(Sardinella aurita),which increased by 13.035 times before the artificial reef dropped.Both the results of trawl net and gill net indicated that the effect of fish assemblage were evident,and the community structure had improved greatly.It showed a wonderful effect on conservation and assemblage of fishes resource.The artificial reefs developed a new resource enhancement system in the east corner of Zhelang Shanwei accomplished basically. | Lichen FANG Pimao CHEN Guobao CHEN Yong TANG Huarong YUAN Xue FENG | 2013 | Asian Agricultural Research2013，5，9： | 2 |
| 2 | Research Advances in Hydrodynamics of Artificial Reef显示文摘With further recession and deterioration of offshore fishery resources and increasing living demands,construction of marine ranching becomes a focal point to improve marine biological resources and environment,while artificial reef is one of the important parts for marine ranching construction. The artificial reef technology develops slowly in China compared with developed countries,such as the United States and Japan,and there are still many issues urgently to be solved.When an artificial reef is released in water,there are various kinds of forces,and its forces and flow field-effect are closely related to surrounding conditions and its own performance. Currently,there are no mature conclusions on research of hydrodynamics of artificial reef. According to review of hydrodynamics of artificial reefs,we hope to give a full understanding on hydrodynamics performance of artificial reefs,and provide reference and theoretical basis for further research on design and structure of artificial reef in China. | Fan Jiangtao Chen Pimao Feng Xue Chen Guobao | 2014 | Animal Husbandry and Feed Science2014，6，3： | 1 |

| 4 | Preliminary Study on Feeding Habits of Anthocidaris crassispina显示文摘Employing experimental-ecological methods,the feeding and vitality of adult Anthocidaris crassispina were investigated. The results showed that A. crassispina exhibited an obvious preference on five different seaweeds,with the preference order of Betaphycus gelatinum > Sargassum hemiphyllum > Gelidium amansii> Ulva lactuca > Codium fragile. The daily feed intake of A. crassispina differed among U. lactuca,S. hemiphyllum and B. gelatinum. The feeding was affected by water temperature,seaweed species and body weight. The optimal vitality and feed intake were observed under 23-27℃,which were inhibited under whether too higher or too lower temperature. Under the optimal temperature for feeding,the daily feed intake of adult A. crassispina assumed an exponentially-decreasing trend with increase of body weight. | Nie Yongkang Li Yong Zhou Zhigang Chen pimao Hong Jiezhang Huang Zeqiang Zhou Yanbo Qin Chuanxin Feng Xue Yuan Huarong | 2017 | Animal Husbandry and Feed Science2017，9，2： | 0 |
| 5 | Current Situation, Problems and Countermeasures of Marine Ranching Development in Guangdong Province, China显示文摘Combining the literature review and marine field investigation in the sea area,this article summarized the development and current situation of marine ranching at home and abroad.It analyzed the construction process of artificial fish reefs,proliferation and release,and national-level marine ranching demonstration areas,as well as the current development situation and existing problems of marine ranching-related industries in Guangdong Province.Guangdong has built 50 ecological artificial reef areas,3 large-scale artificial reef demonstration areas,1 local artificial reef area and 15 national marine ranching areas,with a total sea area of 1499.68 km^(2),and 2.004 million m^(3) of reefs.However,there are some problems in Guangdong marine ranching,including imperfect management mechanism,inconsistence in development concept and understanding,unclear rights and responsibilities in using sea area,lack of construction technology standards and specifications,low scientific and technological level and limited industrial development.In view of these problems,this article came up with countermeasures,including insisting on ecology-prioritized development,and strengthening the coordination of multiple departments;creating a management mode conducive to market-oriented operation;breaking through the issue of sea area ownership;establishing a technical standard system for marine ranch construction in Guangdong;strengthening the research on the basis of high-quality construction and key common technologies of Guangdong marine ranching;establishing industrialization modes of Guangdong marine ranching according to local conditions.Understanding the development status of marine ranching in Guangdong and exploring the development strategies of marine ranching industry by referring to the relevant experience at home and abroad can provide references for the effective management,efficient and sustainable development of marine ranching in Guangdong and the integration of three industries in the development of marine ranching in Guangdong. | Huarong YUAN Pimao CHEN | 2022 | Asian Agricultural Research2022，14，11： | 0 |
| 6 | Seasonal Variations in Fishery Resources in Shenzhen Sea Area显示文摘Seasonal variations and causes for these were elaborated for fishery resources in Shenzhen sea area,to provide scientific basis for sustainable utilization and management of fishery resources in typical fisheries of South China Sea coasts. Based on the data of fishery resources collected through trawl surveys in Egong Bay fisheries area,Shenzhen,from August( autumn) and December( winter) of 2012 to March(spring) and May(summer) of 2013,seasonal variation of nekton species composition,stock density,dominant species composition,size spectra and biodiversity were studied. Results showed that there were 113 species of nekton in Shenzhen sea area,which belonged to 78 genus,50 families,14 orders and 3 classes. The number of species was the largest in summer(61 species) and smallest in autumn(53 species). In spring and winter,there was 56 species. The stock density and individual density of nekton were the minimum in summer(5950. 20 kg/km2 and 356. 45 ind/km2,respectively),whereas the percentage of fish stock density and individual density were the highest in summer(51. 99%and 42. 19%). The seasonal variations of size spectra indicated that fishing intensity was the highest in autumn,and was the lowest in summer. Additionally,biodiversity index presented significant seasonal variations,including Shannon-Wiener diversity index( H '),Margalef richness index( D') and Pielou evenness index( J'),with the same trend as summer > spring > autumn > winter. In conclusion,there are clear seasonal variations in the nekton species,biomass and structure in Egong Bay fisheries area in Shenzhen. Due to the difference in fishing intensity in different seasons( low intensity in summer and high intensity in autumn),community structure and function in summer are more stable than that in autumn and winter. Particularly,with the increase in the fishing intensity in autumn,k selection species will be replaced by r selection species. | Jiangmei MAO Huarong YUAN Jing YU Pimao CHEN Qiwei HU | 2017 | Asian Agricultural Research2017，9，9： | 0 |
| 7 | Evaluation on Fishery Resources in Daxingshan Artificial Reef Area of Huidong County显示文摘In order to evaluate placement of artificial reefs in Huidong County and observe biological aggregating effect of fishery resources,background investigation and follow-up investigation were carried out for trawl fishing and gill-net fishing in Daxingshan artificial reef area.The biological resource density index(D),Margalef species richness index(R),Shannon-Winener diversity index(H'),and Pileou evenness index(J')were used to study diversity of water biological population and resource density.Trawl fishing investigation indicated that after placement of reefs,there was significant increase in quantity of species of nekton,total resource density,species richness index,and diversity index in reef area,which were 1.321,2.07,1.012 and 1.084 times the value before placement of reefs respectively.Gill-net fishing investigation indicated that after placement of reefs,the quantity of species of nekton,total resource density,species richness index,and diversity index in reef area were 2.571,7.976,2.399 and 2.667 times the value before placement of reefs respectively.After reef placement,fishes and crabs become dominant population.It showed that after reef placement,attraction effect of fishes is significant,community structure is obviously optimized,and water environment in reef area is significantly improved.Thus,it proved that the multiplication system through artificial reefs has been basically established in Daxingshan reef area of Huidong County. | Xue FENG Pimao CHEN Huiquan LI Jiezhang HONG | 2013 | Asian Agricultural Research2013，5，12： | 0 |
| 8 | Effect Evaluation of Summer Fishing Moratorium (SFM)in Daya Bay Based on Remote Sensing and Survey Data显示文摘[Objective] The paper was to quantitatively evaluate the maintenance effect of summer fishing moratorium(SFM) in Daya Bay. [Method]Based on satellite remote sensing and trawl surveys, the changes in sea surface temperature(SST), chlorophyll a(Chl-a) concentration, catch per unit effort(CPUE), biodiversity, species composition, body length and weight of total catch in Daya Bay before SFM(May 2015) and after SFM(August 2015) were comparatively analyzed. [Result] The CPUE of total catch mainly distributed from 0-10 kg/h before SFM to 0-40 kg/h after SFM. The average body length and weight of catches increased, indicating that the growth rate of catches was accelerated. The indices of Shannon-Wiener diversity index(H′) and Pielou evenness index(J′) increased by 0.36 and 0.14, respectively, indicating that the community structure was improved. The biomass spectra of fishery resources community suggested that the slopes of normalized biomass spectra after SFM was greater than -1, and the biomass of fishery resources increased with the increase of individual body weight after SFM. SFM reduced offshore fishing intensity,recovered and conserved the fishery resources in Daya Bay. [Conclusion] In order to improve the SFM system and promote the sustainable development of coastal fishery resources, it is suggested to prolong the time of SFM appropriately, reduce the number of coastal fishing boats, and strength-en the conservation of fish resources. | yu jing hu qiwei chen pimao mang qi | 2018 | Animal Husbandry and Feed Science2018，10，4： | 0 |
| 9 | Ecosystem Health Assessment of the Egong Bay Fisheries Area in Shenzhen Based on Index of Biological Integrity of Fish显示文摘[Objective] The ecosystem health of the Egong Bay fisheries area in Shenzhen was assessed,based on the index of biological integrity of fish( F-IBI),for the reference of ecological restoration in typical fisheries area in the coast of South China Sea. [Method]Based on four seasons survey from August( summer) and November( autumn) in 2012 to February( winter) and May( spring) in 2013,six indicators including total species number of fish,percentage of Sciaenidae species,percentage of Sparidae species,percentage of planktivorous species,percentage of benthic-feeding species and percentage of benthic-feeding and piscivorous species,were used in computing F-IBI of Egong Bay. The suitability of F-IBI was tested by principal component analysis( PCA) and Pearson correlation analysis. [Result]Total species number of fish,percentage of Sciaenidae species,percentage of Sparidae species,percentage of planktivorous species and percentage of benthic-feeding species were major assessment indicators for Egong Bay fisheries area. F-IBI of Egong Bay fisheries area was correlated with water temperature,salinity,chemical oxygen demand( COD) and petroleum,and was negative correlation to p H,dissolved oxygen( DO),dissolved inorganic nitrogen( DIN),reactive phosphate( PO_4^(3-)-P),and suspended matters. There were significant correction between the F-IBI with the salinity,COD,and suspended matters.[Conclusion]F-IBI system,based on total species number of fish,percentage of Sciaenidae species,percentage of Sparidae species,percentage of planktivorous species,percentage of benthic-feeding species and percentage of benthic-feeding and piscivorous species was feasible in Egong Bay fisheries area. | Yu Jing Chen Pimao | 2017 | Meteorological and Environmental Research2017，8，6： | 0 |
| 10 | Density,Storage and Distribution of Carbon in Mangrove Ecosystem in Guangdong's Coastal Areas显示文摘Using the mangrove plants and sediment of the typical mangrove areas in Guangdong's coastal areas,P. R. China as the research object,the density,storage and spatial distribution of carbon are studied. The study method is the combination of the wild field analysis and laboratory testing method. The results show that the carbon density of the sediment will gradually decrease because of the increased depth,and has nothing to do with the difference of the area and tree species. The average carbon density of 50 cm sediment is 0. 007 g C / g. The carbon density is obviously different in different components of different mangrove species in different regions. The total carbon storage in different regions is in the following order: Zhuhai > Gaoqiao > Shenzhen > Shuidong Bay > Guanghai Bay > Raoping > Daya Bay > Chenghai. The carbon density and carbon storage are obviously higher in mangrove covered area than blank area. It shows that mangroves have very strong carbon sink function. | Na LI Pimao CHEN Chuanxin QIN | 2015 | Asian Agricultural Research2015，7，2： | 0 |
