有害赤潮藻对浮游动物影响的研究进展

有害赤潮藻对浮游动物的影响在赤潮危害的研究中越来越受到关注，本文综述了有害赤潮藻对浮游动物的毒害作用，主要表现为影响浮游动物的存活和生长，降低母体的产卵力、卵的受精率或受精卵的孵化率以及减慢胚胎发育或造成畸形，影响幼体的正常发育，抑制浮游动物的摄食和改变其正常行为等；这些毒害作用主要是由赤潮藻产生的藻毒素或其它一些胞外渗出物通过降低浮游动物对食物的利用率、造成生理损伤、破坏细胞膜、降低亲体产生的配子质量、抑制有丝分裂和胚胎发育等造成的．某些赤潮藻营养成分单一如缺乏多不饱和脂肪酸，也会对浮游动物的生长繁殖产生影响．

Research advance in effects of harmful algal bloom species on zooplankton

The research on the effects of harmful algal bloom (HAB) algae on zooplankton has been drawn more and more attention. This paper summarized the adverse effects of HAB algae on zooplankton,which included reduced survival,inhibited growth,reduced fecundity of female, fertilization failure of eggs or hatching failure of zygote,inhibited embryo development,naupliar abnormal development or abnormality,inhibited grazing and changed behavior of zooplankton, etc. The main intoxication ways included decreased utilization of food,physiology impairment,damaged cell membrane,reduced gamete quality,and inhibited mitotic and embryo development by phycotoxins or exudations released by algae. Additionally, the lack of full nutrition,especially of polyunsaturated fatty acids in some algal species cells could also affect zooplankton growth and reproduction.
