海洋噬菌蛭弧菌对对虾病原菌及其他细菌的寄生作用

用宿主双层琼脂平板法，测定海洋噬菌蛭弧菌对２５株对虾病原菌和大肠杆菌、枯草杆菌、绿脓杆菌及金黄色葡萄球菌的寄生作用，结果表明噬菌蛭弧菌菌株不同寄生的范围不同，但所有供试寄主细菌都能被某些蛭弧菌寄生，形成清晰的噬斑．用相差显微镜和电镜观察蛭弧菌的形态及噬菌过程     

海洋浮游植物自动分析和识别技术

浮游植物是海洋生态系统的初级生产者．对其种类的分类鉴定和定量分析是海洋科学研究和应用的基础性工作．传统的分析方法主要采用显微镜下的人工鉴定和定量计数．为了适应海洋科学和环境监测中的快速检测的需要，解决目前显微镜人工鉴定中存在的专业水平要求高、分类人员断层、耗时等问题，至今已有不少学者对各种浮游植物自动分析和识别方法进行了研究．包括基于藻细胞形态的与计算机技术相结合的图像法，基于藻类色素组成的吸光光度法、荧光分光光度法和高压液相色谱法．基于藻细胞大小、色素组成、DNA等的流式细胞仪法，基于细胞基因系列的分子探针法等．本文对这些方法的原理、发展动态、优缺点等进行了综述．认为基于藻细胞形态的浮游植物显微图像自动识别技术，由于其综合了现代仪器自动分析和传统显微分类方法的优点，是浮游植物自动识别的一种理想和实用的方法，将有很好的应用前景．     

The morphology of Anophrys arenicola sp. nov. (Ciliophora,Scuticociliatida)

The morphological characteristics of a new species of cilitated protozoan, Anophrys arenicola, are described. The structure of the infraciliature (arrangement, composition, number of kinetosomes and the oral and somatic fibril systems) are described in detail. In addition, a quantitative study of the variation of the principal morphological components has been made through the use of a new modification of the silver carbonate method.     

Some helminth parasites of marine fishes of South Africa: families Enenteridae,Opistholebetidae and Pleorchiidae (Digenea)

The following digeneans are described, recorded or figured from South African waters: Enenterum kyphosi and E. mannarense from Kyphosus vaigiensis; E. elsti, E. prudhoei, E. stinkvis sp. nov. and E. tongaatensis sp. nov. from Neoscorpis lithophilus; Pseudozakia hatampo from Pempheris oualensis; Opistholebes cotylophorus from Amblyrhynchotes honckenii; and Pleorchis sciaenae from Argyrosomus hololepidotus. The other taxa discussed are: family Enenteridae; genus Enenterum (including a key); and genus Opistholebes (syn: Pseudoheterolebes).     

A new genus and two new species of cirolanid isopod Crustacea from the northern Indian Ocean

A new genus of cirolanid isopod Atarbolana, and two new species, Atarbolana exoconta and Cirolana manorae, are described. Atarbolana is distinguished from related cirolanid genera by having a projecting clypeus, pleon with three free tergites, and cylindrical uropod exopod.

Cirolana manorae is most similar to Cirolana bovina Barnard, and new figures are given for that species.     

Dipteran infestation of loggerhead (Caretta caretta) and green (Chelonia mydas) sea turtle nests in northern Cyprus

This paper describes dipteran infestation of loggerhead (Caretta caretta) and green (Chelonia mydas) sea turtle nests in northern Cyprus in 1996 and 1997. Insect larvae were collected from infested nests, reared to adulthood and identified to species. A minimum of 13.4% (1996) and 17.4% (1997) of loggerhead turtle nests and 3.3% and 20.7% of green turtle nests were infested in 1996 and 1997, respectively. Eleven dipteran species were found infesting turtle nests with one species (Sarcotachina aegyptiaca) being dominant. Gross estimates, utilizing the speeds of development for three species of sarcophagid showed that infestation was taking place differentially between the two turtle species. Various aspects of the effect of dipteran infestation on marine turtle nests in northern Cyprus and recommendations for future investigations are discussed.     

Morphological studies on a new species of Orthodonella,with redescription of O. gutta (Cohn, 1866) Kahl, 1931 (Protozoa: Ciliophora: Synhymeniida) from coastal water off Qingdao,China

The morphology and infraciliature of two marine synhymeniid ciliates, Orthodonella apohamatus nov. spec. and Orthodonella gutta (Cohn, 1866 Cohn, F. 1866. Neue infusorien im seeaquarium. Zeitschrift für wissenschaftliche Zoologie, 16: 253–302.  [Google Scholar]) Kahl, 1931 Kahl, A. 1931. Urtiere oder Protozoa I: Wimpertiere oder Ciliata (Infusoria) 2. Holotricha außer den im 1. Teil behandelten Prostomata. Tierwelt Deutschlands, 21: 181–398.  [Google Scholar], collected from coastal water off Qingdao, China, were studied on living cells and using protargol silver impregnation. The diagnosis for O. apohamatus nov. spec.: marine Orthodonella with length×width about 60–160×20–35?µm in vivo; lanceolate body shape with conspicuous beak-like projection at anterior end; 42–60 (mean 53) somatic kineties, including 28–42 on ventral and 13–20 on dorsal side; synhymenium with about 54–62 dikinetids; pharyngeal basket composed of 8–13 rods; four contractile vacuoles, two in middle near left margin and two at posterior end of cell; one elongated macronucleus and one micronucleus. Based on a Qingdao population, an improved diagnosis for the poorly known species, O. gutta is suggested: marine Orthodonella in vivo about 140–200×60–100?µm; body widely ellipsoidal with contractile beak-like anterior end; 62–74 (mean 66) somatic kineties with ca 41–48 ventral and 20–26 dorsal; synhymenium consisting of 43–70 dikinetids; 11–14 pharyngeal rods; one to several contractile vacuoles distributed in caudal area of cell; numerous cortical granules tiny and colourless; one ovoid macronucleus.
