Two types of Overfishing are mentioned in fishery industry management; one is the Biological Overfishing which is due to overfish catches of fish by human beings, the other is Economic Overfishing, which is due to the excessive investment of fishery equipment from fisherman. Both types of Overfishing could cause the serious damage of fisherman who depends on the fishery resources.

Yellow-throated marten\'s relationship is between Stone marten and Fisher marten.Fisher marten is the first species who was divided from Martes.The second one were Yellow-throated marten and Stone marten.Based on the analysis of the fossil note,Martes came from Central Europe,Fisher marten,Yellow-throated marten and Stone marten belonged to a branch which evolved to temperate zone.Boreal forest martens was another branch which evolved to cold environment.It is suggested that Yellow-throated marten and Fisher martenwere ascertained genus separately.4、By contrasting and analyzing 11 complete mitochondrial control region gene sequences of Mustelidae,the extended termination associated sequence domain、the central domain and the conserved sequence block domain were identified.A extended termination associated sequence(ETAS1) and eight conserved sequence(CSB-F、E、D、C、B、1、2、3) was indicated,and sequence mode was presented.Different kind of short repeat sequences were found between CSB1 and CSB2.With wolf as the outgroup,the phylogenetic evolution relationship of Mustelidae was analyzed using the neighbor-joining method.

而基于鼬亚科动物线粒体DNA12种重链编码蛋白基因序列及石貂和貂线粒体ND2和cyt b全序列,以狼、狗獾和水獭为外类群,应用NJ、MP和ML法构分别构建貂属和貂熊的系统进化树,结果表明:紫貂与日本貂亲缘关系较美洲貂近,石貂与真貂亚属亲缘关系较近,黄喉貂介于石貂和貂之间;貂是最早从貂属分化出的种类,其次是黄喉貂和石貂;结合化石记录分析,貂属起源于中欧地区,貂、黄喉貂和石貂属于一个向温带进化的分支,而真貂亚属为另外一个向寒冷环境进化的分支,建议将黄喉貂和貂分别定为单独的属。4、比对并分析11种鼬科动物线粒体DNA控制区序列,识别出延长终止序列区、中央区和保守序列区3个区域,指出了一个终止相关序列ETAS1及8个保守序列(CSB-F、E、D、C、B、1、2和3),并给出了序列通式,在CSB1和CSB2之间发现具有不同形式的短串联重复序列。

Furthermore, the structure of drift trammel net, set longline of baited hooks and jig and their fishing methods were described.(2)The fishing gears in Hejiang section were divided into drift trammel net, set longline and jig according to the fishery status in Hejiang section."Number of fishing boat day" was selected as the unit of fishing effort.

2根据合江江段的业现状,将该江段的具分为三层流刺网、饵钓、滚钩和其它偶见具四类,以"船·天"作为捕捞努力量的单位,用单位捕捞努力量获量乘以年捕捞努力量分别得到这四类具的年获量,并将这四类具的年获量相加估算出合江江段1999-2002年的获量分别为104563.464kg、65564.231kg、123684.966kg和107285.272kg。

There are reduced 31.89% and 27.45% in numbers and weight to compare with the same period of 2003. The numbers and CPUE of catches of sharptail ocean sunfish are highest in the first season of 2003 and 2004. Many bigger fishes had caught from May to July in different years. The relation between numbers of catches and mean of air temperature reveals that there are two peaks of catches in 18℃ and 28℃.

The results showed that there were many coastal and epibenthile species, dominate fishes and crabs with significant monthly variation in composition, in the by-catch of shrimp beam trawls in waters surrounding Naozhou Island had. The average ratio of by-catch to shrimp was found to be 6.83:1 in weight and 2.5:1 in value, indicating that relatively high percentage of by-catch and less by-catch discards were the main problems in shrimp trawls.

结果表明:硇洲岛周围水域虾拖网副获种类多,主要为沿岸性底栖种类,组成结构存在明显的月变化,其中蟹类和鱼类是影响副获组成结构和月变化的优势类群;副获海上抛弃率很低,兼捕现象严重是现阶段虾拖网的主要问题,副获与目标虾类的平均重量比为6.8:1,平均产值比为2.5:1。

After three years' spring fishing off, dominances of the main species decreased, CPUE of part reaches increased, and Margalef diverdity index, Pielou evenness index and Wilhm Modified Shannon-Wiener diversity index of the three reaches showed the rising tendency, which indicated the richness of species number and complication of community structure, and the positive ecological effects by the spring fishing off.

春禁后,获物主要种类优势度有所下降,部分江段单位捕捞努力量获量表现出一定上升趋势,3个江段Margalef指数、Pielou指数和Wilhm改进指数有一定升高,表明种类丰富度有所提高,群落结构趋于复杂,春季禁有一定效果。
