摘要:
研究不同光照度对异养鞭毛虫Paraphysomonas sp.摄食及抑制铜绿微囊藻(Microcystis aeruginosa)的影响,探讨鞭毛虫在不同光照条件下的生长状况。共设6个光照度,分别是0、500、1 200、2 500、5 000、10 000 lx。结果表明,不同光照度对异养鞭毛虫种群生长率、微囊藻抑制率均有显著影响(P<0.05)。在光照度为0~10 000 lx时,鞭毛虫均能显著抑制微囊藻种群生长,抑制率达88%~94%,每个鞭毛虫摄食率高达32~49个/d。伴随着铜绿微囊藻数量的减少,不同光照度下的鞭毛虫种群数量均呈先增加后减少的趋势,鞭毛虫种群数量高达(18~35)×104个/mL,比初始浓度增加了3.6~7倍。光照度最高组(10 000 lx)的异养鞭毛虫数量增长缓慢且快速下降,在试验的第3、4 天,生长率出现负增长。因此,过高的光照度会抑制异养鞭毛虫数量的增长。异养鞭毛虫可生长的光照度范围为0~10 000 lx,最佳生长光照度为0~5 000 lx。
