Integration of an Individual-Based Fish Bioenergetics Model into a Spatially Explicit Water Quality Model (CE-QUAL-ICM)

摘要

This technical note presents the results of incorporating a fish bioenergetics module into CE-QUAL-ICM, a spatially explicit eutrophication model. In addition to fish consumption of algae, zooplankton, and detritus, fish biomass accumulation and recycling to the water column are explicitly accounted for. Schools of fish are tracked individually, allowing for spatial resolution of their effects on phytoplankton and nutrient loading. These developments allow for investigations of the impact of planktivorous fish on water quality through consumption of algae and nutrient export via mass sequestering during growth. The formulation details of the new model system are outlined in this technical note.
