低盐度养殖池塘常见浮游微藻的种类组成、数量及优势种群变动

Common species composition, quantity variation and dominant species of planktonic microalgae in low salinity culture ponds

  • 摘要: 于2007年9月至2008年1月在广东珠海地区对低盐度养殖虾池水体的浮游微藻进行全程周期性调查分析。结果共检出常见浮游微藻5门31属49种,其中绿藻13属22种,蓝藻9属16种,硅藻6属8种,裸藻2属2种,隐藻1属1种。优势种有13种,主要是蓝藻,有铜绿微囊藻(Microcystis aeruginosa)、圆胞束球藻(Coelosphaerium naegelianum)、卷曲螺旋藻(Spirulina spirulinoides)、假鱼腥藻(Pseudoanabaena sp.)、绿色颤藻(Oscillatoria chlorine)、拟短形颤藻(Oscillatoria subbrevis)、粘连色球藻(Chroococcus cohaerens)、点状平裂藻(Merismopedia punctata)和针状蓝纤维藻(Dactylococcopsis aciculari)。其次是绿藻和硅藻,有蛋白核小球藻(Chlorella pyrenoidosa)、多粒衣藻(Chlamydomonas.multgranulis)、角毛藻(Chaetoceros sp.)和新月菱形藻(Nitzschia closterium)。低盐度虾池养殖周期浮游微藻细胞数量为0.1107~209.2107 indL-1,多样性指数平均为2.5~3.2。浮游藻类的种类数、数量及多样性指数总体表现为养殖前期低后期高的特征。

     

    Abstract: In order to understand the variation of planktonic microalgae in low salinity culture ponds of Litopenaeus vannamei, investigations on the planktonic microalgae species and quantity were conducted from September 2007 to January 2008. The results showed that a total of 49 species of microalgae was identified in the culture ponds, belonging to 7 phyla and 62 genera, respectively. They included 22 Chlorophyta spcies, 16 Cyanophyta species, 8 Bacillariophyta species, 2 Euglenophyta species, and 1 Cryptophyta species. Many of the 13 dominant species belonged to the Cyanophyta, including Microcystis aeruginosa, Coelosphaerium naegelianum, Oscillatoria chlorine, Pseudoanabaena sp., Spirulina spirulinoides, O. subbrevis, Chroococcus cohaerens, Merismopedia punctata and Dactylococcopsis aciculari. The other dominant species belonged to Chlorophyta and Bacillariophyta, including Chlorella pyrenoidosa, Chlamydomonas.multgranulis, Chaetoceros sp. and Nitzschia closterium. In low salinity culture ponds, the quantity of planktonic microalage ranged from 0.1107~209.2107 indL-1, and diversity index averages were at 2.5~3.2. The species numbers,quantity and diversity index were low in early culture period and high in post culture period.
