The core concept of TAPAS is to provide tools to investigate carrying capacity categories of freshwater and marine aquaculture in terms of recent regulation, policies, and indicators of sustainability while remaining focused on the most relevant problems of the aquaculture industry. The sustainability of aquaculture has to be ensured by applying a holistic view in developments as well as in the management of existing facilities. This method is described in the aspects of the ecosystem approach to aquaculture (EAA) saying that aquaculture activities should always be within the carrying capacity of the ecosystem. Carrying capacity in aquaculture production can be defined as the level of resource use both by humans or animals that can be sustained over the long term by the natural regenerative power of the environment.
