硅藻对渔业的支撑作用与负面效应探讨

Discussion on Sustaining Function and Negative Effect of Diatom on Fishery

传统认为,硅藻在水域食物链"硅藻—桡足类—鱼类"中起着支配作用,但近来的研究结果对此认为提出了质疑。为了深入探明硅藻在其中的作用机理,从硅藻对渔业正反两方面的作用进行了综述分析。

It was traditionally thought that diatom played predominant role in the food chain ＂diatom-copepods-fish＂ of water area, but it was questioned by the recent research result. In order to further clarify the function of diatom in the food chain, summery and analysis from the two sides of positive and negative effect of diatom on fishery were conducted. Result showed that diatoms had admitted roles in fishery-providing orimary food oroduction, however, the negative effect also existed.
