Abstract
从2007年5月~2008年4月,采用悬挂试网和直接从海区采集栉孔扇贝养殖笼样品两种方法,对桑沟湾贝藻养殖区的附着生物群落结构和季节演替规律进行了研究。结果显示,桑沟湾附着生物群落结构复杂,本实验鉴定的大型附着生物23种,玻璃海鞘、柄海鞘和紫贻贝是群落中的优势种。附着生物的生物量呈现明显的季节变化特征,试网上附着生物湿重与温度变化相关,生物量为0.003~1.21kg/m2,其中2月和8月分别具有最小和最大值。栉孔扇贝养殖笼的附着生物生物量9月为1.94kg/笼,之后随温度下降而减少,10月为0.99kg/笼,之后又有所上升,11月份为1.03kg/笼。生物量变化主要是由于优势种的演替引起的,随温度下降海鞘类逐渐消退,贻贝等成为优势种。
