Large-Scale Operations Management Test of Use of the White Amur for Control of Problem Aquatic Plants. Report 2. First Year Poststocking Results. Volume VII. A Model for Evaluation of the Response of the Lake Conway, Florida, Ecosystem to Introduction of the White Amur.
Abstract
Simulation of a model summarizing relationships between major biotic and abiotic components in Lake Conway, Florida, indicated that the establishment of significant growths of submersed plants had enabled nutrients in sediments, previously removed from the mainstream of nutrient cycling, to be reintroduced into the water column where stimulation of phytoplankton production can occur. Internal recycling of phosphorus by submersed plants was estimated to represent nearly half of the annual phosphorus input to the lake. Apparently, nutrient loading from outside sources has declined over the last few years, and the simulation showed slowly declining submersed plant biomass and productivity after six years as nutrients were washed out. Phytoplankton biomass and productivity also began to decline after six years.
