  • Description:
    Carrying capacity models for aquaculture have increased in complexity over the last decades, partly because aquaculture growth, sustainability, and licensing are themselves extremely complex. Moreover, there is an asymmetric pattern toall these components, when considered from an international perspective, because of very different regulation and governance of the aquaculture sector in Asia, Europe, and America. Two case studies were used, from Long Island Sound in the United States, and Belfast Lough, in Europe, to examine the interactions between cultivated shellfish and other autochthonous benthic filter-feeders. The objective is to illustrate how such interactions can be incorporated in system-scale ecological models and analyzed from the perspective of ecological carrying capacity. Two different models are described, one based on equations that relate the filtration rate of the hard clam Mercenaria mercenaria to physiological and population factors and one based on a habitat-specific analysis of multiple species of benthic filter-feeders. Both types of models have relative advantages and challenges, and both wereintegrated in ecosystem modeling frameworks with substantial numbers of state variables representing physical and bio-
