Discards, the parts of a fish which are not kept after cleaning them
Canada has also instituted a ban on discarding at sea in its Atlantic groundfish fishery that makes it illegal to return to the water any groundfish except those specifically authorised and those caught in cod traps.
Neoclassical economics also follows this lead — and that of Jevons, Menger, and Walras — from the 1870s and discards the LTV in favour of general equilibrium theory, which determines prices based on the interaction of preferences, technology and endowments through supply and demand.
The fishing sector in Argentina had been declining for years as a result of overexploitation and high discard rates; the important Argentine hake catch in particular had declined by around 70% since the mid-1990s.
