中国海首次发现的海洋污染研究实验动物——毛轮沙蚕

我们在进行黄海毯形帚虫Phoronis ijimai Oka生态研究时,在青岛的阴岛潮间带,发现了属于环节动物门Annelida、多毛纲Polychaeta、矶沙蚕科Eunicidae、豆维沙蚕亚科Dorvilleinae的毛轮沙蚕Ophryotrocha puerilis Claparde et Metschnikov,这在中国海是首次记录。 一、毛轮沙蚕在海洋污染研究中的重要意义 海洋污染调查研究的实践证明,沿岸地区很容易受到污染物的影响,由于自然环境的复杂,进行污染研究必须判明是自然现象,还是由于污染造成。尤其是评价污染对沿岸底栖生物的影响,问题更为复杂,因为在海洋这样开阔的混合水域内,对生物的影响可能是很多物质混合作用的结果。为此,只有通过长期的实验工作、生物属种的正确鉴定和广泛

TEST ANIMAL (OPHRYOTROCHA PUERILIS CLAPAREDE ET METSCHNIKOV) FOR THE STUDY OF MARINE POLLUTION IN THE CHINA SEA

In working on the polychaetous annelids from the China Sea, an interesting species-Ophryotrocha puerilis Claparede et Metschikov was found in the Yellow Sea.Ophryotrocha puerilis is a common test animal for the study of marine pollution. This species is for the first time from Chinese waters used for this purpose.Ophryotrocha puerilia is produced in abundance in the littoral zone of Tsingtao. Judging from its geographical distribution, it can be considered as a temperate and tropical waters cosmopolites.Ophryotrocha puerilia stays on muddy stone when tide is low and water relatively quiet; usually in Phoronis ijimai Oka community.Bioassay studies customarily use polychaetes of the genus Ophryotrocha as test animal. Ophryotrocha puerilia is much preferred, of which the reproductive capacity is one of the most important parameters.Based upon what the view point of marine ecosystem is, this paper tries to emphasize the importance of meiobenthos for the study of marine pollution.
