Set-nets are common alongshore fishing gear used in Haizhou Bay, which rely on flow to catch fish. The catch per unit effort（CPUE） of set-net is affected by spatial-temporal and environmental factors but no research has been conducted on this subject. In this study, we used generalized additive models（GAMs） to explore the influence of spatial-temporal and environmental factors on CPUEs of species aggregated, small yellow croaker（Larimichthys polyactis）, and octopus（Octopus variabilis） based on logbooks investigations conducted at 4 stations in an alongshore area of Haizhou Bay from 2011 to 2012. The results showed that all CPUEs exhibited significant spatial-temporal differences at various scales. Aggregated CPUE was high when the sea surface temperature（SST） was 15-18℃ and 20-23℃, which was mainly determined by life history traits of the octopus and small yellow croaker（optimal SSTs 14-17℃ and 19-24℃, respectively）. Chlorophyll-a concentration had significant influences on the aggregated, small yellow croaker and octopus CPUEs at optimal ranges of 3.8-6.2 mg m-3, 4.2-4.8 mg m-3 and 4.5-5.5 mg m-3, respectively. Flow through the net had positive relationships with CPUEs. The approximate logarithmic trends in regression curves had a critical point of 2.5 Mm3 d-1, which was the dividing point that differentiated whether the major factor affecting CPUEs was the flow velocity or the fishery resource. Our results from this study will help guide fishery production and improve catch rate of set-net fishing in Haizhou Bay.

目的研究大鼠新生儿期母子隔离(NI)和新生儿期抚触刺激(NTS)对成年后社交行为,下丘脑室旁核(PVN)和视上核(SON)的催产素(OXT)、精氨酸后叶加压素(AVP)表达神经元数量的影响。方法将78只大鼠分到正常对照(SFR)组、母子隔离(NI)组、抚触刺激(NTS)组,于新生儿期进行相应干预,待大鼠成年后进行社会交往能力测试及神经元数量测定。结果大鼠新生儿期间的母子隔离对成年后的社交行为有不良影响,且这种行为改变在子代雌鼠的社会交往及同性社会交往时的缺陷更加明显。NI组雌鼠OXT免疫组化染色阳性神经元数量在PVN的大细胞区域显著下降,AVP免疫组化染色阳性神经元数量在PVN的大小细胞区域亦显著下降。新生儿期抚触刺激可部分逆转这些行为和分子上的变化。在雌鼠中PVN的OXT和AVP免疫组化染色阳性神经元数量与社交行为呈正相关(r^2=0.277,P=0.044;r^2=0.325,P=0.017)。结论新生儿期母子隔离和抚触刺激可能通过PVN的OXT/AVP系统,对雌鼠的社交行为产生长期影响。

Anaerobic fermentation can increase biomass energy use efficiency of crop straws and realize win-win of energy and *** paper explored the biogas generation performance of anaerobic digestion of cow dung liquid as nitrogen source in three different levels of stirring intensity at 30℃ constant temperature condition. Through p H value,biogas production,chemical oxygen demand( COD),methane content,volatile fatty acid( VFA),principal component analysis( PCA) and modified Gompertz model,effects of agitating intensity on anaerobic digestion performance of corn straw silage were evaluated. Results indicate that the COD removal rate of three agitating intensity levels is higher than 85%,and p H value is about 6.5; the cumulative biogas production after 20 days is 2h > 4h > 1h of agitating; in the49 th day,the biogas production is 1.9 Lat 30 min /2h,1.7 L at 30 min /4 h,and 1. 6 Lat 30 min / h; the maximum biogas production rate is 30 min /2h > 30 min /4h > 30 min / h; and the maximum methane production rate is 30 min /4h > 30 min /2h > 30 min / h; in the same energy consumption,the biogas production at 30 min /4h is higher than 1h. In conclusion,overall analysis of energy consumption and economic factors indicate that 30 min /4 h agitating intensity is more suitable for straw biogas fermentation project. This study is expected to provide theoretical foundation for biogas fermentation project.

作者： Yaoquan HAN Anyou HE Li HUANG Jun SHI Dapeng WANG Weijun WU Guangxi Key Laboratory of Aquatic Genetic Breeding and Healthy Aquaculture Guangxi Academy of Fishery Sciences Guangxi International Business Vocational College

Through analysis on water quality,planktonic organism,fish resources,and fish species diversity in Yantan water area,this paper evaluated current situation of quality of fishery ecological environment in Yantan water area. The survey recorded all 52365 fishes and 1410. 2kg catches obtained by fishermen in half a year,and more than 98% catches are small fishes. The Shannon-Weiner diversity index of Yantan water area is 0. 162,Wilhm improvement index is 1. 814,DG- Findex is 0. 083,and the index of fish species diversity is far lower than other water areas. The average quantity per unit of phytoplankton is 1. 0134 million ind. / L,and the average quantity per unit of organisms is 1. 1151 mg / L. The average quantity per unit of zooplankton is 459. 6 ind. / L,and the average quantity per unit of organisms is 0. 6422 mg / L. Evaluation results indicate that water quality and planktonic organism in Yantan water area are basically normal,but fish resources are increasingly exhausted,fish resource composition is not reasonable,and fish species diversity is extremely low. From the perspective of biomanipulation,it is required to restore fishery ecological environment of reservoir area through restoring normal composition of aquatic organisms.

Soil Erodibility of Slope Farmland in Guizhou Mountain Areas

Asian Agricultural Research 2014年第5期6卷 86-89页

作者： Jian LI Li CHENG Zhenggang CHEN Qing ZHU Guizhou Soil and Fertilizer Institute Meteorological Bureau of Guizhou Province

This paper studied soil erodibility of slope farmland in Guizhou mountain areas by the plot runoff method,analysis and test. Results show that the variation coefficient of erodibility K value calculated according to formula introduced by Sharply is low and relatively stable and accurate,so it is a suitable method for calculating erodibility K value of slope farmland in Guizhou mountain areas. K value of layer A slope farmland decreases with increase of years. The erodibility of entire soil layer is high,and the erosion resistance is weak. From the influence of different planting system and use types in 4 years,K values of different soil layers decrease,average reduction of A,B and C layers reaches 3. 17%- 11. 64%( 1. 26%- 12. 34% for layer A,1. 29%- 13. 80% for layer B,and 1. 26%- 10. 80% for layer C). Except engineering terraced treatment,the decline of K value of grassland,zoning crop rotation,economic fruit forest,grain and grass intercropping,plant hedge, and mixed forest treatment is higher than farmers' treatment,and the decline level is grassland > zoning crop rotation > economic fruit forest > grain and grass intercropping > plant hedge > and mixed forest treatment. Planting grass and trees is favorable for lowering erodibility of slope farmland and improving farmland quality. Interplanting of corns with other plants can increase plant coverage and species,so it is favorable for improving erodibility of slope farmland.
