摘    要:2004年3月到2005年2月,在福建围头湾深水网箱养殖区开展污损生物周年挂网调查.共记录污损生物154种,隶属于12个生物门;全年网衣都有污损生物附着,冬季和春季优势种为细枝仙藻、中胚花筒螅和长颈麦杆虫,主要影响网箱内外水体交换,夏季和秋季优势种为网纹藤壶,容易导致网衣磨损,影响网箱安全;各月份附着生物量差异极大,平均附着生物量表层网片449.42 g/m2,最高峰出现在4月份,底层网片580.25 g/m2,最高峰出现在3月份.季度平均生物量表层网片3142.30 g/m2,底层网片6030.97 g/m2;春季表层网衣藻类特别多,中胚花筒螅、网纹藤壶和麦杆虫等数量远大于港湾内网衣或试板的污损生物量,呈现海区透明度大及抗动荡环境的特点,与港湾内网衣或试板有较大差别.

关 键 词:污损生物    深水网箱养殖    福建围头海域

Abstract:The Weitou Bay, with wide mouth open to the Taiwan Strait, is located in the middle of Fujian Province.From March 2004 to February 2005, the netting test panels, which were made of blacknetting of PA210D/26×3-60 fixed on rigid frame of 50 cm, were laid down in the open ocean cageaquaculture area of the Weitou Bay in order to examine the set tlement and stat us of fouling organisms.154 species were recorded with the dominants of Ceramium tennuissmun, Tubularia mesembry anthemum, Caprella equilibra in spring and Balanusreti culates in summer.The monthly average biomass of fouling organisms was 449.42 g/m2 in the depth of 1 m and 580.25 g/m2 in 4.5 m, and the highest amount appeared in April and March respectively.The seasonal average biomass was 3 142.30 g/m2 in the depth of 1 m and 6 030.97 g/m2 in 4.5m, and the highest amount occurred in spr ing and summer respectively.The fouling organisms in open ocean cagearea occurr ed throug hout the year but is much different from the inner bay, where the biomass of Ceramium tennuissmun, Tubularia mesembry anthemum, Caprella equilibra and Balanus were much smaller than that in the open ocean cage culture area.
Keywords:Weitou Bay of Fujian Province  fouling organisms  cage culture area
