Integration of ecosystem-based models into an existing interactive
web-based tool for improved aquaculture decision-making
Proper site selection is critical to the development and expansion of marine aquaculture. Major considerations for
site selection include: potential for competing uses, environmental interactions, and animal productivity. Two
types of existing site selection tools, mapping and modeling, have proven useful independently, and in some recent
studies have proven useful when used together. GIS-based mapping tools have become important in the
decision-making process. These tools provide access to marine and coastal datasets allowing farmers and extension
agents to gather information on availability of cultivation sites. They are also used by resource managers to
assess potential use conflicts (e.g. existence of commercial fishing, mooring areas, fixed fishing gear) and possible
environmental interactions (e.g. presence of seagrasses, contaminants, threatened or endangered species).
Models have been used separately to predict animal growth, farm productivity, and farm-related effects on the
surrounding water and sediment quality.
