附着生物广泛分布在海洋、港湾、河口从及江河湖泊和水库中的船底、管道和水中一切设施的表面上。国内外对海洋附着生物的生态已做了不少的调查研究工作,对淡水附着生物生态研究的报导还不多。进行淡水或咸淡水的附着生态研究,对于比较研究海洋附着生物是很有意义的;我国有许多河港,所以更必须调查研究这些港湾的附着生物。 自1974年3月至1975年2月,在宁波白沙浮码头分表、底两层挂板。这里离海不远,水位和水质都受到涨落潮水的影响。退潮时基本上是余姚和奉化两河流来的淡水,几乎测不出含氯量有显著增加,常年全年大潮含氯量0.10—11.57g/Kg,小潮0.03—0.55g/Kg。水色混浊,呈土黄色,透明度经常在0.1米以下。
Attached organisms are widely distributed in the surface of the ocean, bays, estuaries, rivers and lakes and reservoirs in the bottom, pipes and all water facilities. At home and abroad, a lot of investigations and studies have been done on the ecology of the marine attached organisms, and there are not many reports on the biological ecology of freshwater attachments. Studying freshwater or brackish water attachment ecology is of great significance for comparative study of marine attachment organisms. There are many river ports in our country, so it is even more important to investigate the attachment organisms in these harbors. From March 1974 to February 1975, Ningbo Baisha Floating Terminal Sub-table, the bottom two pegboards. Not far from the sea here, the water level and water quality are affected by the tide. At low tide it is basically freshwater from Yuyao and Fenghua Rivers. Almost no measurable increase in the amount of chlorine is found. The annual tide contains 0.10-11.57g / Kg of chlorine and 0.03-0.55g / Kg of tide. Aqua cloudy, yellowish, often less than 0.1 m in transparency.
