Just a pointer for now but the gist is that tradeable quotas improves fisheries in more ways than one:
Our study shows that by adding a key missing ingredient -- economic incentives -- to fisheries management, we can:
* protect the environment,
* increase profits,
* provide higher quality fish,
* create more full-time jobs, and
* save lives.This study documents how fisheries in the United States and British Columbia have performed against key environmental, economic and social goals since converting from conventional management to catch shares.
