Ecosystem Indicators of Water Quality Part I. Plankton Biomass, Primary Production and Nutrient Demeveral lines of evidence point to the conclusion that primary production in SWNB is under light rather than nutrient control and that phytoplankton there have limited capacity to process additional nutrients produced as aquaculture in the region expands. The ratio of bacterial abundance to phytoplan

Ecosystem Indicators of Water Quality Part II. Oxygen Production and Oxygen Demand, may be better indicators of the seasonal regulation of oxygen dynamics by the ecosystem. Low DO is the cumulative effect of sustained oxygen demand; a seasonal change in P/R from greater to less than 1 is an early warning of this demand. The application of both indices (P/R and DO) in tandem can be

Much of the coast is exposed to high-energy conditions often with an effectivefetch exceeding 700 km. Inner basins of some bays and fjords are protected from the waves associatedwith such exposure and may naturally experien

Organic Enrichment from Marine Finfish Aquaculture and Effects on Sediment Biogeochemical Processes plants and fauna due to progressive oxygen depletion. In warm temperate waters, such as the Mediterranean and tropical latitudes, many farms are located in more advective areas with coarse-grained carbonate-rich sediments. Effects of organic enrichment in these areas are less well described, but st
