青岛旅游商品开发的回顾与前瞻

青岛旅游商品开发拥有辉煌历史，曾经领导全国消费潮流。但从旅游经济产业结构来看，青岛旅游商品开发存在如下问题：缺乏品牌和特色商品，小规模开发与经营，品种和质量有待加强，流通渠道不畅，购物环境不理想和商品的旅游后影响力不强等。提出相应开发对策；政府宏观指导，名企参与开发，丰富品种和特色，完善购物环境，使物流渠道畅通，将市场分类分层，利用节庆造势，周边联合连动和形成购物胜地。     

光合细菌在对虾育苗生产中的应用

１９９５年４月２４日～５月８日，在文登高岛盐场育苗场５０ｍ３水体育苗池，进行了用几株光合细菌（ＲｈｏｄｏｐｓｅｕｄｏｍｏｎａｓＳ．Ｐ．）混合菌液作为中国对虾（Ｐｅｎａｅｕｓｃｈｉｎｅｎｓｉｓ）苗期水质净化剂及辅助饵料，取得了明显效果。育苗池水透明度提高约２０ｃｍ，幼体挂脏率下降５０％，变态提早１ｄ左右，且多产仔虾百万尾

Molecular identification of bloom-forming species Phaeocystis globosa (Pryninesiophyta) and its dispersal based on rDNA ITS sequence analysis

The colony-forming Phaeocystis species are causative agents of dense bloom occurrences in coastal waters worldwide. It is difficult to separate them because of the different morphologies associated with their colonial stages. In this study we applied molecular approaches to analyze the genetic variation of Phaeocystis globosa and Phaeocystis pouchetii from several geographic regions, and to assist in tracing the dispersal of bloom-forming Phaeocystis species in coastal waters of China. The sequences of the internal transcribed spacers (ITS1 and ITS2) of rDNA and the 5.8S ribosomal RNA gene of Phaeocystis strains were determined. Sequence comparison shows that P.globosa was the most divergent to P. pouchetii, exhibiting sequence divergence higher than 0.08. However, lower genetic divergences existed between strains of P.globosa. The sequence comparison of the Phaeocystis rDNA ITS clearly shows that the species isolated from the southeast coast of China is identified as P.globosa rather than P. cf. pouchetii or other species. Furthermore, the significance of rDNA variation in distinct global populations of P.globosa suggested it might have had sufficient time to accumulate detectable mutations at the rDNA locus, supporting the hypothesis of ancient dispersal of P.globosa to many areas, meaning that P.globosa blooms in the coastal waters of China are endemic rather than a newly introduced species or a foreign source. Finally, based on the high divergent region of rDNA ITS, a pair of species-specific primers for P.globosa were designed, they could be useful to detect the presence of this species in mixed plankton assemblages or flagellate stages that are recognized with diffculties by means of conventional microscopy.     

东山湾贝类养殖容量的估算

以初级生产力为基础，应用营养动态模式和沿岸海域能流分析模型，估算东山湾贝类年生产量分别为269331t和295767t，平均282549t。扣除潮间带、潮下带和吊养区浮筏、随着基及延绳上附着的非养殖滤食性附着动物自然现存量35760t，贝类可养殖量为246789t。应用统计分析和逻辑斯谛种群增长模型估计贝类可养面积为11839hm^2，其中缢蛏635hm^2，石蛎1160hm^2,吊蛎1525hm^2，翡翠贻贝633hm^2，菲律宾蛤仔1154hm^2，扇贝698hm^2，江瑶248hm^2，泥蚶601hm^2，巴非蛤4151hm^2，凸壳肌蛤1034hm^2。1998年实际养殖面积和养殖产量分别为10581hm^2和220564t。尚有1258hm^2,26225t的扩大开发潜力。文中还讨论了合理布局和优化养殖结构问题。     

褐牙鲆(♀)、夏鲆(♂)及其杂交子一代线粒体16S rDNA序列遗传特性的初步研究

以线粒体16S rRNA基因部分片段为代表研究雌褐牙鲆Paralichthys olivaceus、雄夏鲆P. dentatus及其杂交子一代间线粒体DNA的遗传特性。母本与父本序列差异较大,属种间差异,在590个位点中有28个变异位点,而且全部为简约信息位点。使用同一对引物扩增亲本与杂交子代,在杂交子代中未检测到父本的线粒体DNA类型,11个处于两种生长阶段的杂交样本仅检测到一种单倍型,而且与母本的一个单倍型为同一种,表明褐牙鲆与夏鲆杂交线粒体DNA遵循母系遗传规律。

Long baroclinic Rossby waves with periods of about 500d near 20°N in the northwest Pacific Ocean

On the basis of maps of sea level anomalies data set from October 1992 to January 2004, pronounced low frequency variations with periods of about 500 d are detected in the area near 20°N from 160°W to 130°E. A linear two-layer model is employed to explain the mechanism. It is found that the first-mode long baroclinic Rossby waves at 20°N in the northwest Pacific propagate westward in the form of free waves at a speed of about 10.3 cm/s. This confirms that the observed low frequency variabilities appear as baroclinic Rossby waves. It further shows that these low frequency variabilities around 20°N in the northwest Pacific can potentially be predicted with a lead up to 900 d.
