Interest in the effect of fish farming practices on §the marine environment has arisen as there is §concern that the wastes that fish farms produce may §be contributing to eutrophication in coastal areas §and harmful algal blooms. The focus of this book is §an examination of phytoplankton distribution and §abundance in relation to tuna fish farms in Boston §Bay and near-shore Spencer Gulf. This is the first §study in South Australia to define the short-term §biomass fluctuations of chlorophyll and in vivo §fluorescence, identify phytoplankton species §distribution and abundance, including two §potentially toxic dinoflagellates, and describe §patch distribution relative to tuna fish farms in §Boston Bay and the near-shore waters of Spencer §Gulf. An ecological interpretation of phytoplankton §distribution and abundance is determined. Pico- and §nanophytoplankton were often the most abundant §organisms. Diatoms and gymnoids were most common. §Season and currents predominantly influenced the §distribution of phytoplankton in Boston Bay and §Spencer Gulf. Individual species may be influenced §by inputs from the fish farms.
