Abstract:The current exploitation of cephalopod resources in the globe are briefly described in this paper. The catch and main cephalopod species in eight important statistical fishery areas are also analyzed. The cephalopod catch in Northwestern Pacific have persistently taken first place and have been continuously increasing since 1990s. In 1995 its catch data accounted for 35. 3% in the total cephalopod catch. In this paper, the development of Chinese distant-water squid jigging fishery is simply introduced as well.After having 8 years developed, it has become a pillar industry in Chinese marine fisheries,and fishing grounds are widely distributed in Japan sea, Northwestern Pacific, New Zealand around waters and Argentine coastal waters. Finally some suggertions about developing squid jigging fishery of China are put forward in the future.

Abstract:The period of development of feeding organs is long in paddlefish, Polyodon spathula. Fish feed live food organisms by oral and teeth until 65. 5mm total length. In this stage, oral width and diameter developed quickly, and the size of food organisms is more than 0. 3mm. Gill rakers were not well developed until 65. 5mm of total length. The increasing rate of length and filtering-size of gill rakers is exponential in relation to the total length of fish. The diameter of food organisms which could be filted between gill rakers is more than 0. 1mm which is similar to that of another filt-feeding fish, big head carp (Aristichthysnobilis). The relationship between quantitative characters of feeding organs and change of feeding behaviour was discussed in this paper. Against the total length of paddlifish, the regression analysis of those quantitative characters was also made.

Abstract:采用性腺组织切片观察与繁殖行为观测相结合的方法，对温室养殖中华鳖的性泉发育进行研究。试验结果表明温室中养殖的中华鳖不仅生长速度加快，而且性发育也提早。中华鳖在温室条件下下饲养１０个月时，雌鳖的卵核完全移至动物极并贴近卵膜，雄鳖的精巢内已有大量的精子生成，切开输精管有大量乳白色的精液流出。雌鳖性成熟年龄为２１个月，雄鳖性成熟年龄为１０个月。

Abstract:溶氧量是衡量水产养殖水体水质的重要指标，以物理方法即采用高频电场处理主池养殖水，然后通过管道深层压入空气，改变传统的释放头对养殖池水曝气加氧，使养殖池水的平均溶氧量在不断被消耗情况下。

Abstract:利用开阔型港湾紫菜养殖埕地空闲季节，进行小型试验并指标大面积轮养菲律宾蛤仔，选择含沙星８０％－９０％的沙泥稳定底质，海水比重１．０１６－１．０２２，大潮干露２－４小时，流速８０－１００厘米／秒，饵料丰富的海区，１－２月份播种壳长２．０－２．２厘米的一龄大蛤苗，密度１０００个／米＾２。

Abstract:本文采用聚丙烯酰胺凝胶水平电泳和激光扫描法，研究了中华鳖ＬＤＨ、ＭＤＨ、ＥＳＴ、ＳＯＤ、ＩＤＨ、α－ＧＰＤＨ、Ｇ－６－ＰＨＤ同工酶在肌肉，肝脏，肾，心，脾，精巢，卵巢等组织器官中的表达，并对其遗传位点进行了分析。在研究的７种同工酶中，除ＭＤＨ在各组织中表型一致外，其他同工酶均有明显的组织特异性。

Abstract:Editorial management of academic periodical is more compact and complex as compared with general periodical- According to the character of editorial management of academic periodical, this paper abstracts a data process diagram about editorial management system of academic periodical by systematic analyses in a deep going way and using a method of software engineering. And concrete data store model is achieved with E-R diagram designing data store. Edited and debugged with relation data language of Visual FoxPro 5. 0. Such a sort of system has five functions of manuscript management, statistics, report forms outputting, inquiring and retrieving, system defense.
