摘 要: 本文结合光镜与扫描电镜技术,对杂色鲍培苗膜上的藻类进行了初步分析,结果表明:杂色鲍培苗膜上的藻种类多,有不同大小、不同形态的卵形藻、舟形藻、菱形藻、羽纹藻、直链藻、针杆藻、绿藻等类型。在附苗状况良好的薄膜上,卵形藻为优势种。而在附苗状况较差的薄膜上,舟形藻成群分布,较为大型的绿色藻类及直链藻分布较多。文中记述了主要的14个较为清晰的藻种,它们分别为扁圆卵形藻变种、盾卵形藻微尖变种、舟形藻未定种、小型舟形藻未定种、小型羽纹藻未定种、中型羽纹藻未定种、斜纹藻未定种、琴式菱形藻、直链藻未定种、针杆藻未定种、新月菱形藻、长菱形藻、细柱藻未定种和念珠直链藻。所记述的种类均附有相应的实物照片,并有相关的测量数据。

Abstract: In the paper, light and scanning electric microscopic techniques were used to analyse the algae on the breeding biofilms for juvenile Haliotis diversicolor. The results showed that there were many kinds of algae on the breeding biofilms, such as Cocconeis, Navicula, Nitzschia, Pinnularia, Melosira, Synetra and green algae in different size and shape. On the biofilm which juvenile abalone grew well, Cocconeis were the dominant species, while on the film which juvenile abalone grew badly, Navicula were the dominant species, and they often grew together, and there were more green algae and Melosira in larger size. Meanwhile, the main fourteen clear algae species were recorded and described in the paper. They were Cocconeis Placentula var., Cocconeis scutellum var., Navicula sp1., Navicula sp2., Pinnularia sp1., Pinnularia sp2., Pleurosigma sp., Nitzschia panduriformis, Melosira sp., Synedra sp., Nitzschia closterium, Nitzschia longissima, Leptocylindrus sp., and Melosira moniliformis. For all the recorded species, there were photos enclosed and the relative data were measured.
