effective fishing effort
fishing effort, e.g. hooks per day, adjusted or standardised, when necessary, so that each increase in the adjusted unit causes a proportional increase in instantaneous rate of fishing. Controls purported to limit effective effort imply that the fishing mortality rate is to be limited. Abbreviated as F/q, F/q, f or f
