沙埕港污损生物的生态研究

Ecological studies on fouling organisms at Shacheng Harbour

1990年3月至1991年2月，在闽浙交界处的沙埕港进行周年污损生物挂板试验，共记录生物70种。其中，海藻13种，动物57种。以泥藤壶、网纹藤壶、僧帽牡蛎、中胚花筒螅、太平洋侧花海葵、香港网筛苔虫和多种端足类为优势种，全年有生物附着，夏、秋、春、冬季的优势种有显著不同，优势种突出，附着量特别大，夏季底层板（6～8月）的湿重生物量达28．03kg／m2，为目前全国沿岸港湾生物量之冠。

From March, 1990 to February, 1991,an annual panel test on fouling organisms was carried out in Shacheng Harbour,between Fujian and Zhejiang Province. Seventy species were recorded, 13 algae and 57 animals. The dominant species were Balanus uliginosus, Balanus reticulatus, Crassostrea cucullata, Tubularia mesembryanthemum, Anthopleura sp. Cosciniopsis hongkongeasis and several amphipods. Bioattachment occurred throughout the year, but with distinct difference of dominant species among summer,autumn,spring and winter. The dominant species were conspicuous and the biomass was particularly large. The wet weight on summer (June^August) bottom layer panel reached 28. 03 kg/m2,being the greatest of the biomass of fouling organisms in all the coastal harbours of the country that have been tested.
