Because aggregate capture fisheries output growth is static,
demand increases should raise the price fish harvested from them.
However, Tveterå se tal.(2012,p7) report that although this has
happened to alimited degree since 2000, ‘ substitution will
dampen price pressure as the demand spills over to farmed fish’.
As a result, significant divergence in capture fisheries and farmed
fish prices is unlikely. This effect is pronounced for salmon (Knapp
et al.,2007) and shrimp (Marks, 2012), but also occurs among
capture fisheries and aquaculture products for which the degree of
substitution is less perfect.
