In addition, these systems improve safety by reducing incentives for fishermen to go out ( or stay out ) when weather conditions are dangerous. Tradable quotas also eliminate government's motivation for curtailing the length of the fishing season. Prior to the establishment of quotas for Alaskan halibut, for example , the government had reduced the fishing season to just two days. Subsequent to the introduction of the system, the season grew to more than 200 days. That means a longer season of fresh fish consumers.
