人工养虾池生态系统结构特点及其控制对策

There is a very simple and weak structure of ecosystem eomposeingof producer and primary comsumer in shrimp culture pond. Where theorgsnic detritus input rate into sediments and eutrophication are allheigh. In this environment,phytoplancton always queatly bloom, sometimeblue or green algae are dominant, diversity index is lower and bacteriaor virus devolep greatly. For protecting the culture environment andproduction we consider it is important to control accumulating rate ofdetritus in sediments of culture pond by standing benthos feedingdetritus in it. taut to control accumulating rate ofdetritus in sediments of culture pond by standing benthos
