From bioeconomic theory it is well known that the long-term fish catch supply is normally described by a backward-bending supply curve (the blue curve in the upper figure of this Demonstration). The shape of the supply curve reflects the bell-shaped growth curve of the stock biomass and the catch equation of the fishery; see the Gordon–Schaefer model shown by the green curve in the lower figure.
