ABSTRACT
The herbivorous fish Ctenopharyngodon idella, commonly called the white amur or Chinese grass carp, appears to be the most promising organism available for biological control of many submersed aquatic plant problems. Study drafts a statement regarding the possible impact of white amur fish on the natural aquatic ecosystem. There are several components that most lake ecosystems have in common. The detailed composition and operation of the components, plus the effect of external physical forces acting on them, distinguish lakes from one another. Therefore, the model that is used to initiate an effort is usually general and is then refined according to specific characteristics of each ecosystem. When white amur was used alone as a management strategy, it achieved a higher standing stock than under conditions of management by herbicide and white amur combined because more food was available for the white amur to eat. As with the native fish component, more work is needed to refine the biomass number.
