This survey covers both direct and indirect environmental impacts. It is often difficult to distinguish clearly between these two types of impacts. The direct impacts may derive directly from certain properties of the aquaculture project itself. The indirect impacts may result from other types of activities in association with the project, e.g. processing. Indirect environmental impacts can also occur if the project alters socio-cultural conditions in the local community, e.g. through changes in the power structure.
