Recently, there has been a growing concern that increased aquaculture production
poses an environmental threat to the species targeted in so-called reduction fisheries,
the main source for fishmeal. The argument is that increased aquaculture production
leads to higher feed demand, and then presumably to higher fishing effort in these
fisheries. In this paper we address whether aquaculture production threatens
sustainability of such fisheries. First, we ask under which management regimes can
increased demand pose a threat to the species in question? Second, we investigate what
is the market for fishmeal; is fishmeal a unique product or is it part of the larger market
for protein meals which includes Soyameal? This is an important issue since the market
structure for fishmeal is a key factor in determining whether increased aquaculture
production can affect fishmeal prices, and thereby increase fishing pressure in
reduction fisheries.
