Calvert cliffs acoustic finfish surveys, 1977. Final report

Technical Report ·
OSTI ID:6850610
Acoustic surveys were performed at the Calvert Cliffs nuclear power plant site in the Chesapeake Bay in 1977 to determine if plant operations have significantly affected the density and distribution of pelagic finfish in the Bay. Concurrent midwater trawling indicated that bay anchovy were the dominant pelagic fish species in the area. Spectral analysis of series of density estimates along transects revealed some of the distributional characteristics of fish. Large-scale spatial trends comparable to transect-length scales were the most frequently observed distribution pattern. No plant effects on distribution or density became evident. Using average biomass density, average annual impingement of bay anchovy amounted to 4% of the average standing stock in the Calvert Cliffs area of the Bay.
