New Zealand stopped fishers racing by giving each a permanent slice of the catch

By the early 1980s New Zealand's inshore fisheries were, in a former Ministry of Fisheries deputy chief executive's words, "the wild west": too many boats chasing too few fish, with stocks on the verge of economic collapse. Because no fisher owned any fish until it was physically caught, every boat had an incentive to catch as much as possible as fast as possible, since anything left in the water would likely be taken by someone else first.

Regulators had already tried the standard toolkit — size limits, gear restrictions, closed seasons, area closures, even outright moratoriums on new entrants — but these input controls kept failing, since boats simply fished harder and more efficiently within whatever limits remained. By 1984, officials concluded that regulating how fishing happened couldn't fix a problem rooted in who owned the fish.

The Fisheries Amendment Act 1986 introduced the Quota Management System, allocating every existing fisher a permanent Individual Transferable Quota (ITQ): a fixed percentage share of the government's annual Total Allowable Catch for a given species in a given area, based on that fisher's prior catch history. Unlike a boat-by-boat catch limit, an ITQ was a tradable property right — fishers could catch their share whenever it was most economically sensible, or sell or lease it to someone else entirely.

Gave each fisher a permanent, tradable percentage share of the total catch, so catching your share no longer depended on beating anyone else to the water.

No one owned fish until caught, so every boat raced to catch as much as possible first.

Input controls only changed the terms of the race, not the incentive to race.

A permanent quota made catching speed irrelevant, so the race disappeared.

Tradability let quota flow to efficient fishers, raising asset value even as catches were cut.

When a shared pool is destroyed by a race to grab it, stop regulating the race and instead give each participant a permanent, tradable ownership share of the pool itself.

Because each fisher's share no longer depended on beating every other boat to the water, the incentive to overinvest in bigger boats and race for fish disappeared, replaced by a market in harvesting rights that rewarded efficiency and let capital flow toward whoever could fish a given quota most profitably. A Statistics New Zealand study later found that between 1996 and 2009 the asset value of the original 26 QMS species rose 18 percent even as their combined catch limits were cut 40 percent to let stocks rebuild.
