Bigeye tuna(Thunnus obesus)is one of the most important fish species in Marshall Islands *** is a growing need to describe the spatial extent and suitability of bigeye tuna habitats. A common approach to that is to construct spatially explicit habitat models from fisheries-independent survey data.A survey on tuna fishing ground was carried out in Marshall Islands waters from Oct, 2006 to May,*** tuna’ s catch rates(inds per 1 000 hooks)in each fishing day were calculated. The depth at which each bigeye tuna was hooked was estimated using a stepwise regression analysis of theoretical hook depth and observed average hook depth measured using a temperature depth *** temperature,salinity,dissolved oxygen and thermocline,which are important environmental variables influencing bigeye tuna habitats,were measured in the *** regression was used to estimate the maximum extent and suitability of bigeye tuna habitats,*** potential or upper limits of the habitat,in Marshall Islands *** in bigeye tuna’ s catch rates according to changes in environmental variables was estimated using regression quantiles,BLOSSOM statistical software was used to estimate regression quantile parameters,and backward elimination method was used to select significant environmental variables affecting bigeye tuna *** integrated habitat index(IHI)varying from 0 to 1 was developed to describe suitability of bigeye tuna habitats in different *** maps of bigeye tuna were also built using ARCGIS *** IHI model was validated by comparing predicted relative abundances against independent catch rates data of the commercial fishing fleet of china’s mainland fished in Marshall Islands waters from 2006 to 2007. Modelling the upper bounds of relationships between bigeye tuna and its habitat enables the detection of the effects of limiting factors on bigeye tuna’ s responses,and therefore this work have subsequent benefits for bigeye tuna’ s

The central dogma of radiation biology is that the cytotoxic and mutagenic effects of radiation are principally the result of biological macromolecules(DNA,RNA, polysaccharides,proteins and lipids) damage caused during the course of irradiation. Previous studies on the radioresistance of the extremely radiation-resistant red-carotenoid-pigmented bacterium Deinococcus radiodurans have been focused on

针对目前东海区普遍使用的蟹笼(笼径60cm,笼高25cm,外罩网衣网目尺寸2a=32mm)对三疣梭子蟹幼蟹资源损害较严重的现状,选择设计了在其框架结构上开设横向幼蟹释放口的选择性蟹笼,于2009年11月在32°30’～33°00’N、124°00’～124°30’E海域进行了海上生产性试验。结果表明:释放口高度与可从其逃逸的三疣梭子蟹的最大甲高趋于一致,如以125g作为三疣梭子蟹的最小可捕体重标准,用甲高与体重的关系式可求得选择性释放口的高度为33mm;释放口的选择曲线可用分段函数表示且无50%选择甲高,这不同于拖网、捕虾衍拖网与帆式张网网囊及捕鳗笼的网目选择曲线,后者可以用'逻辑斯谛选择曲线'模拟,且存在50%选择体长;采用各甲高组的平均选择率表示尾数选择率,经过卡方(χ2)检验,其生产性试验值小于20%,同时释放效果明显;释放口对逃逸幼蟹的存活率几乎不产生任何影响。本研究成果可供管理部门在制定三疣梭子蟹的最小可捕标准时参考。

Effect of regional warming on the abundance of P seudeuphausia sinica Wang et Chen(Euphausiacea)off the Changjiang River(Yangtze River)Estuary

Acta Oceanologica Sinica 2011年第6期30卷 122-128页

Distribution and abundance of Pseudeuphausia sinica off the Changjiang River Estuary （30 ° 00′ – 32 ° 00′ N, 122 ° 00′ –123 ° 30 ′E）, the east china sea were studied in relation to environmental features associated with the regional warming. P. sinica is a subtropical species. Off the Changjiang River Estuary, its abundance reached maximum in summer. To examine spatial and temporal changes of P. sinica off the Changjiang River Estuary, the authors have combined all available sampling data in 1979, 1981, and 2000–2007. This database shows that a significant increase in abundances of P. sinica was observed in spring of 2000–2007 as compared with 1979, 1981. The abundance of P. sinica increased from 0.18–0.21 ind./m 3 in 1979 and 1981 to 0.68–4.00 ind./m 3 in 2000–2007. Accordingly, the sea temperature increased obviously from spring of 1979, 1981 to the 2000s. The authors further found a positive relationship between average surface temperature and average abundance of P. sinica. Regional warming, together with the release of predator induced stress due to a sharp decline in the abundance of its predator （e.g., fishes）, were thought to be responsible for the increase in abundance of P. sinica in water off the Changjiang River Estuary.

Study on spatial and temporal distribution of planktonic amphipoda in the east china sea

Acta Oceanologica Sinica 2004年第2期23卷 329-336页

作者： JIANGMei WANGYunlong YUANQi CHENYaqu eastchinaseafisheriesresearchinstitute ChineseAcademyofFisherySciencesShanghai200090China

Quantitative distribution of planktonic amphipoda in the east china sea is analyzed and the relation with environmental factors and mackerel and scad fishing grounds is studied. The result shows that the characteristic of biomass is great seasonal and interannual variety during the passing three decades. The distribution of planktonic amphipoda basically reflects the movement, decay and intensification of the different water systems in the survey area.

Distribution characteristics of zooplankton biomass in the east china sea

引用

Acta Oceanologica Sinica 2004年第2期23卷 337-346页

作者： XUZhaoli CHAOMin CHENYaqu eastchinaseafisheriesresearchinstitute ChineseAcademyofFisheriesSciencesShanghai200090China KeyandOpenLaboratoryofMarineandEstuarinefisheriesofMinistryofAgricultureofchina Shanghai200090China

On the basis of the data of oceanographic survey in the east china sea in four seasons during 1997-2000 (23°30'~33°00'N, 118°30'-128°E), the variation of total biomass and diet biomass of zooplankton and their spatial-temporal distribution and relationship with the fishing ground of Engraulis japonicus are approached and analyzed. The results show that the average biomass is 65.32 mg/m3 in four seasons, autumn (86.18 mg/m3) being greater than summer (69.18 mg/m3) greater than spring (55.67 mg/m3) greater than winter (50.33 mg/m3). The average value of diet zooplankton biomass is 40.9 mg/m3. The trends of horizontal distribution both in the total biomass and the diet biomass of zooplankton are similar. The high biomass region (250-500 mg/m3) is very limited, only accounting for 1% of the investigation area. seasonal variation of the biomass is very remarkable in the west and north parts of east china sea coastal waters ( 29°30'N,125°E). The horizontal distribution of diet zooplankton depends on the abundance distribution of crustacean. The distribution of diet zooplankton is related to the fishing ground of Engraulis japonicus and the high-density area of young fish and larval. In spring, the central fishing ground of Engraulis japonicus (>100 kg/h) and the high-density area of young fish and larval (>100 individuals per net) are located at the same place of high-density (100-250 mg/m3)area of diet zooplankton in the middle-southern part of east china sea or the edge of its waters.
