MARINE STUDIES OF SAN PEDRO, CALIFORNIA. PART 12. BIOENHANCEMENT STUDIES OF THE RECEIVING WATERS IN OUTER LOS ANGELES HARBOR. (REVIEW OF FIELD OBSERVATIONS, ASSIMILATION CAPACITY/OXYGEN BUDGET MODELLING BIOASSAY AND LABORATORY INVESTIGATIONS)
Field studies indicate that the present state of the harbor is healthy. Rich and diverse biotic elements are supported by the present environmental regime. Episodes of stress, which occurred in earlier years, as indicated by reduced levels of dissolved oxygen, have not been noted since the canneries have instituted improved waste management procedures. Bioenhancement is occurring in outer Los Angeles Harbor, due at least in part to the presence of natural waste effluents. Bioenhancement has been evaluated in terms of numbers of organisms and species diversity of plankton, benthic organisms, and standing crop of fish, as well as in biomass and a number of other factors. The regulation of waste loading and control of pollutants in the past six-year period has brought the harbor ecosystem from a depauperate biota to a moderately rich one in the immediate outfalls zone, with a very rich biota in the adjacent outer harbor area.
