根据1997～2000年东海海域23°30′～33°00′N，118°30′～128°00′E的4个季节海洋调查资料，运用定量、定性方法，探讨了东海浮游翼足类总丰度的平面分布、季节变化及变化的动力学机制。

Tilapia is the dominant species in most lakes of South China, and its food includes phytoplankton in open water habitats and periphyton in substrate-surface habitats.

罗非鱼是我国南方很多水体的优势种，食物包括敞水生境的浮游植物和基质表层生境的附着藻类等。

Our field research was the first time to compare the biomass and production of phytoplankton and periphyton before and after the removal of oyster-culture pens at a scale of whole lagoon.

本研究是第一篇藉由大尺度牡蛎养殖移除的野外实验，比较有、无牡蛎养殖对於浮游藻类及附生藻类生物量及生产力的差异。

Also it influenced the growth of algae and the living of shrimps at level of 0.033 mg/L, but no significant toxic effects on other zooplankton such as Daphnia magma, ostracods, rotifers and so on was detected.

结果表明，莠去津浓度为0.023 mg/L时对藻类生长会产生影响；浓度为0.033 mg/L时对藻类生长和河虾生存均会产生影响，但对其他浮游动物，如大型溞、介虫、轮虫等未产生显著的毒性效应。
