Planktonic ostracods are small crustaceans abundant in marine ecosystem worldwide as appreciable part of marine zooplankton. Family Halocyprididae is a large group of halocyprid ostracods, and the tribe Conchoeciini has contained 21 genera previously. We described a further genus with a species Polyconchoecia commixtus gen. et sp. nov. from the middle of South China Sea in this study. The new species can be distinguished from related genera and species in having a unique combination of these characteristics： a lateral gland placed over right asymmetric gland and open near posterior margin; dense edge glands placed along ventral margin of carapace in line; shape of frontal organ; e-seta of first antenna is bare; endopod of second antenna has one small oval hump with central concave on mid-ventral margin, instead of processus mamillaris, exopod 1 has a small disto-dorsal spine, exopod 1 and 2 are fused, exopod 3 and 4 are bare; endopod 1 of mandible has one long ventral seta, endopod 2 has one ventral seta; maxillary endopod 1 has two basal setae; endopod 1 of fifth limb has only one ventral seta; endopod 1 of sixth limb and endopod 2 have no ventral seta. The definite distinctions in locations of major glands are the key characteristics of the new genus.

A prevailing,controversial hypothesis is that fishing pressure has played a greater role than climatic and environmental drivers,in changing fish species succession and biomass fluctuation in the South China Sea(SCS).Based on otter trawl survey data from 1959 to 2010 in the outer Beibu Gulf(OBG),northern SCS,large seasonal and interannual variation is reported for fish species composition,the proportional abundances of dominant taxa,and fish *** additive models are developed to quantify relationships between fish biomass and the external factors of fishing pressure and climate *** pressure proved to be the main driver of sharp declines in demersal fish stocks,with high-value species being replaced by low-value ones over *** decreases in fish biomass during the years of 1993 and 1998 correspond to El Nino events,with climate change possibly the main driver of proportional representation of pelagic species in fisheries trawl *** need to differentiate impacts of fishing and environmental drivers on fish species with different life history strategies is stressed to better understand fish community dynamics.

Length-frequency data of eight commercial fish species in the Beibu Gulf （Golf of Tonkin）, northern South China Sea, were collected during 2006-2007. Length-weight relationships and growth and mortality parameters were analyzed using FiSAT II software. Five species had isometric growth, two species had negative allometric growth, and one species had positive allometric growth. Overall, the exploitation rates of the eight species were lower in 2006 2007 than in 1997-1999： for four species （Saurida tumbil, Saurida undosquamis, Argyrosomus macrocephalus, and Nemipterus virgatus） it was lower in 2006-2007 than in 1997 1999, for two species （Parargyrops edita and Trichiurus haumela） it remained the same, and for the other two species （Trachurus japonicus and Decapterus maruadsi） it was higher in 2006~007 than in 1997-1999. The exploitation rates might have declined because of the decline in fishing intensity caused by high crude oil prices. The optimum exploitation rate, estimated using Beverton-Holt dynamic pool models, indicated that although fishes in the Beibu Gulf could sustain high exploitation rates, the under-size fishes at first capture resulted in low yields. To increase the yield per recruitment, it is more effective to increase the size at first capture than to control fishing effort.

根据1964～1965年及1997～1999年在南海北部采集的深水金线鱼生物学资料,对该鱼种群体结构、资源密度分布及其季节变化、生长和死亡参数及摄食习性进行了研究.结果表明,深水金线鱼的渔获样品体长范围为4.2～21.5cm,体重范围为2.9～241g,分别以9.6～14.0cm和27～59g占优势.资源密度以春季最高、夏季最低,分别为***-2和***-2.分布的区域性变化明显,在水深60～150m之间,深水金线鱼的渔获量随水深的增加而增大.深水金线鱼的食物以长尾类、鱼类和头足类为主.应用FiSATⅡ软件的ELEFANⅠ技术拟合的von Bertalanffy生长方程参数分别为L∞=22.39cm、k=0.44a-1及t0=-0.63a;用Pauly经验公式计算的自然死亡系数为M=0.94;以长度变换渔获曲线法估算的总死亡系数为Z=2.65.运用Beverton-Holt模型分析的结果表明,该群体的最适捕捞死亡系数为F=2.9,最适开捕年龄和体长分别为1.1a和12.0cm.目前该群体已处捕捞过度状态,以捕捞幼鱼问题较为突出.建议南海北部深水金线鱼的最小可捕规格为体长12.0cm.

2004年3月(春季)、5月(夏季)、9月(秋季)和12月(冬季)4个航次对大亚湾海域浮游动物进行了调查。共计鉴定浮游动物128个种类,浮游幼体14个类群。浮游动物出现的种类数依次是:夏季(90种),秋季(81种),冬季(71种),春季(47种)。浮游动物的丰度以夏季最高,平均1013.38 ind.m-3;其次是秋季,平均913.30 ind.m-3;春季最低,平均162.37 ind.m-3。浮游动物生物量的季节变化:秋季(773.89 mg.m-3),夏季(472.82 mg.m-3),冬季(286.44 mg.m-3),春季(164.11 mg.m-3),生物量高低与种类组成关系密切,秋季优势类群为水母类和毛颚类等大型浮游动物,所以生物量较高。4个季节的Shannon-Wiener多样性指数H′值、物种均匀度指数J值和物种丰富度指数D值的变化趋势十分相似:春季的3项指数值均最低,冬季最高,夏、秋季节相差不大。此外,分析结果表明:毛颚类作为优势种且4个季节均有出现,是对大亚湾海域水体较20a前水温上升的响应;浮游动物近岸生物量高于湾中部;从丰度的平面分布看,大亚湾海域浮游动物栖息环境已经不同程度受到大型建设工程和人类活动的影响。
