  abstract: The dissertation describes the development and use of three mathematical models that simulate fisheries and aquaculture ecosystem production, with an emphasis on application of these models in lesser-studied areas of the world. The first model is a general marine fisheries ecosystem model representing the biomass dynamics of phytoplankton, zooplankton, benthos, and both pelagic and demersal fishes. The objective is to provide a quantitative synthesis of available information concerning the trophic dynamics of marine fisheries. The general model could be parameterized under a wide range of environmental conditions representing both subtropical and higher latitude marine fisheries. The fishery submodel represents dynamics of three trophic levels of both pelagic and demersal fishes and also estimates sustainable harvest. The second model is a general extensive aquaculture model representing the biomass dynamics of phytoplankton, zooplankton, benthos, and both planktonic and benthic fishes in response to different levels of chemical fertilization. The objective is to provide a quantitative synthesis of available information concerning the trophic dynamics of aquaculture systems that will be useful in establishing research priorities and management plans, particularly under extensive, as opposed to intensive, culture situations. The model has been parameterized and evaluated based on field data from the subtropics and Egypt. The third model is a live food production model for an extensive aquaculture system representing the biomass dynamics of phytoplankton and zooplankton eggs, nauplii, juveniles, and adults. The objective is to quantify the interrelationships among light, temperature, and level of fertilization affecting production of nauplii (live food) for fish fry. Simulation results are summarized in terms of the capability of pond ecosystems to produce live food under various environmental conditions.
