Larval Fish Feeding Responses to Variable Suspended Sediment and Planktonic Prey Concentrations

Abstract

The purpose of this document is to understand fish feeding responses under conditions that simulate turbidity plumes and variations in prey availability enhances the ability to predict ecological impacts from dredging projects. For example, in the context of nearshore placement of mixed sediments, concerns have been raised that winnowing of fine sediments from deposited dredged material may elevate turbidity and have a detrimental impact on early life history stages of fishes. The feeding responses of larval fishes to varying concentrations of suspended sediments and planktonic prey are reported herein.
