effort restriction
a type of input control used as a management tool whereby the amount of fishing effort expended by fishers in a particular fishery is restricted by law or voluntary agreement among fishers who jointly exploited fishery resource. In practice, as fishing effort is a composite index of various elements, e.g. fishing craft, gear and ancillary equipment, fishing time, etc., it has proven to be difficult to effectively contain its growth in the medium and long term
