This is generally the case for artisanal fisheries of highly valued species such as sole, cod, haddock, shrimps and lobsters. But for some fisheries, such as french industrial fisheries of hake , herring, anchovy, market demand can be low with respect to production. In this context, in order to preserve the economic fishing sector, landing prices are maintained by institutions such as government or producer organizations. When the minimum price is low, the major difference is that the restriction on b no longer holds since a production equilibrium always exists. In the large production region the standard analysis of section 2 applies with as if the price were simply .
Prices damp the oscillations, but the effect is lessened by the existence of a minimum price.
