fishing effort
1) the total fishing gear in use for a specified period of time, expressed as trap hauls for example; when two or more kinds of gear are used, they must be adjusted to some standard type before being added. Successful adjustment should make effort proportional to fishing mortality rate (F), twice the effort giving double the F
2) effective fishing effort, abbreviated as f or f (Ricker, 1975)
3) the amount of time and fishing power used to harvest fish. Fishing power includes gear size, boat size, electronic gear, and horsepower. May be expressed as days away from port, boat days, hours trawling, length of drift net, etc
4) a measure of resource use by anglers, e.g. number of angler hours, party hours, boat hours, trips on the water. Also called fishing pressure
