An Evaluation of Relationships Between Submerged Aquatic Vegetation and Fish Community Structure in the St. Johns River. Final Report

Submerged aquatic vegetation (SAV) such as tapegrass (Vallisneria americana) maybe the most important biological component of the lower St. Johns River that isphysically tied to surface water quality. An understanding of water quality and otherfactors limiting the distribution and abundance of SAV, and how SAV in turn affectsother biota, is fundamental to developing sound management practices for therestoration and protection of natural systems associated with the basin’s surface water.Surprisingly little is known about the importance of SAV to fishes and other aquaticorganisms in the estuarine portion of the St. Johns River. The present study wascarried out to address this gap in our understanding of the St. Johns River estuary andto provide background information for future studies.
