Aquaculture satisﬁes a growing global demand for ﬁsh but also consumes an increasing share of the world’s wild ﬁsh resources. This has led to a concern that increased aquaculture production poses a threat to the sustainability of capture ﬁsheries. We use a shrinkage estimator to estimate ﬁshmeal demand from coun-tries with different make-up of meat and farmed salmon production. Although we are not able to identify structural differences between these sectors, the empirical results show that ﬁshmeal demand is price inelastic. Technological change, however, is reducing ﬁshmeal usage in feeds, suggesting that strong demand pressure on pelagic ﬁsh resources targeted for ﬁshmeal is a temporary phenomenon.
