Effort Limit

An effort limit is an input control that caps fishing effort rather than catch, set as days at sea, vessel-days, gear units, or engine power. It restricts how much fishing can happen instead of how much fish can be landed, the defining feature of input management against output quotas. A total allowable effort is the fishery-wide version of this cap. Effort limits suit data-poor or mixed fisheries where weighing every species is impractical, but they leak: operators offset day caps with bigger engines, more gear, or faster gear, a process called effort creep that erodes the cap’s bite.
