中文摘要:
      研究发现在PO4 P浓度较高且静滞的围隔水体中海洋原甲藻易大量发生形成水华;发生水华后围隔水呈棕红色,浮游植物生物量、叶绿素α、初级生产力、水呼吸、COD和POC等都显著升高,溶解氧和透明度随海洋原甲藻的昼夜垂直迁移表现出相应的昼夜变化;发生水华的围隔内中国对虾和台湾红尼罗罗非鱼尚能存活和生长,但体色暗红,海湾扇贝则全部死亡,表明海洋原甲藻水华对海产贝类的危害较鱼类和虾类更为严重。
英文摘要:
      Occurrence and ef fects of harmful bloom caused by a kind of redt ide algae , Prorocent rum micans , in seawater experimental enclosure were studied .When high conce ntra tion of re act ive phosphate was available and motion of water was weaken in enclosures , phytoplankton was easily dominated by P .micans , and then se rious h armful bloom of the species formed .The color of water in the enclosures with harmful bloom was br own re d at the beginning and turned to black br own at the post stage .Biomass of phytoplankton , chlorophyll α, gross primary production , respirat ion of water column , chemical oxygen demand , and part icle organic carbon were much higher in the enclosure wi th harmf ul bloom than those without bloom.Both dissolved oxyge n and Secchi depth usually varied dr ama tically with diel vert ical motion of P .micans .Ther e were no significant effects of P .micans bloom on survival and growth of Penaeus chinensis and a hybrid tilapia of Oreochromis mossambicus ×O .ni lot icus to be detected although the ir body color became br own red , but mortality r ate of bay scallops stocked in enclosures with serious harmful bloom was 100 %.Clearly P .micans bloom was more harmful to marine bivalves than to f inf ish and pr awn .
