Abstract

It has long been generally accepted that substitution between wild and farmed fish exists when they are of the same species. While this is true for some species and markets, the relation does not hold for all of them. In fact, using cointegration methodology, this paper proves that farmed and wild gilthead sea bream, sea bass and turbot (90% of Spanish marine fish production) are not substitutives in the Spanish seafood market. Those results have implications for policy makers, fishers and fish farmers, stemming from ecological, economical and social sustainability.
