Environmental performance indicators are key to monitoring the sustainability of production processes. In the salmon industry, there is a growing concern about the excess of nutrients that have accumulated at the bottom of marine ecosystems and the negative externalities of those nutrients on the environment. In this paper, we measure environmental performance in the salmon industry in Chile by applying a set of data envelopment analysis (DEA) models. In these models, we incorporate pollutants as undesired outputs of the production process.

The global seafood system includes three interconnected sectors: commercial capture (or wild-caught) fisheries, recreational and subsistence fisheries, and aquaculture (or farmed seafood). The three sector-focused articles in this symposium review production externalities within and between sectors and between the seafood system and the broader natural environment. Building on the insights from these articles, we discuss seafood as part of an integrated food system and examine both seafood supply and demand.
