摘要
1986～1987年对粤东大亚湾的网箱养殖场和马氏珠母贝养殖场网箱和珠贝壳上的污损生物进行研究。共记录 124种生物。优势种是粘附山海绵、总合草苔虫、独角裂孔苔虫、华美盘管虫、放射牡蛎、网纹藤壶、皱瘤海鞘和冠瘤海鞘等。全年都有生物污损。最严重的季节是3月至6月。网箱污损生物的月湿重为8.3—545.0g/m^2;季湿重 150.0—6250.5g/m^2。最大的月覆盖面积为73.4％;季覆盖面积94.9％。网笼受生物污损上半年比下半年严重,最高记录为 4506.2g/m^2。上半年珠贝壳上的污损生物多达50种,最大湿重为 16.5g/1个珠母贝。
Biofouling organisms attached on mariculture cages were studied inDaya Bay, Guangdong province in 1986 to 1987. 124 species of organisms wererecorded. The dominant species were Mycale adhaereris, Bugula neritina, Schizopo-rella unicornis, Hydroides elegans, Ostrea radix, Balanus reticulatus, Styela plicataand S. canopus. These organisms grew throughout the year, and the most flourishperiod was from March to June. The wet weights attached organisms on mariculturecages were 8.3-545. 0g/m^2 monthly and 150.0-6250.5g/m^2 seasonally. The great-est cover areas were 73.4% monthly and 94.9% seasonally. The biofouling onpearlshell cages was more flourish in summer than in winter. The greatest record-ed wet weight was 4506.2g/m^2 on pearlshell cages. In summer, the number of bio-fouling species on pearlshell reached as many as 50 species, when the wet weightreached as high as 16.5 of each pearlshell.
