摘要
研究了1983-1984年和1999-2000年桑沟湾的扇贝养殖区内、外甲藻密度的变化。结果表明:扇贝养殖区内甲藻细胞的绝对密度和相对密度均低于养殖区外;在扇贝存养生物量高且摄食活跃的8月,扇贝养殖区内浮游植物的主要优势种也由甲藻变为硅藻。这表明桑沟湾的扇贝养殖对于甲藻的密度有一定的控制作用。
The variations of dinoflagellate abundance inside and outside the Sanggou Bay scallop culture area during 1983 to 1984 and 1990 to 2000 are studied. It is shown from the study results that the abundance and relative abundance of dinoflagellate cells inside the scallop culture area are lower than those outside the scallop culture area, and the dominant phytoplankton species in the scallop culture area in August with active feeding and high cultured biomass of scallop culture in the Sanggou Bay has a definite control effect on the dinoflagellate abundance in the Sanggou Bay.
