Abstract

The general objective of this study was to assess the relationship between ecological response and quantity and quality of waste input in Galveston Bay, Texas. Specific objectives were: 1) to collect phytoplankton, zooplankton, benthos and nekton at all sampling stations in Galveston Bay and analyze the samples for species diversity, 2) to measure the toxicity of input waters into Galveston Bay on phytoplankton and to determine the water quality necessary for survival and growth of phytoplankton, 3) to determine the relationship between nutrient concentrations and survival and growth of phytoplankton, 4) to study the relationship between river flow and ecological response in a simulated laboratory microecosystem model, 5) to relate ecological response in Trinity Bay to varying flow rate of the Trinity River via the simulated microecosystem approach, 6) to determine the relationship between species diversity (ecosystem response) and quantity and quality of input waste waters, 7) to relate toxicity, nutrient enrichment and flow rates to species diversity at various locations in Galveston Bay so as to provide judgement concerning the design criteria which must be met by any proposed waste management system, 8) to provide ecological cause and effect relationships for future modeling of waste input parameters.
