ESI provides biological aquatic inventory surveys of freshwater mussels, fish, and macro-invertebrates. We have experience in designing surveys in small and large systems for various clients' in-stream construction and dredging permit needs. ESI also provides services for federal and state agencies. Aquatic inventory services include species identification (including federal and state listed species), faunal distribution mapping, formal technical report preparation, and economically feasible mitigation to meet regulatory requirements.
