9.2.2 Fishing effort
9.2.2 Fishing effort
Fishing effort is the product of the amount of gear in use times and the duration of the fishing activity. e.g. trawling hours, pot or trap days, diving hours, hook hours, etc. Clearly each type of gear (trawl, seine, trap, etc.) catches fishes differently. Even within a given gear type, there can be enormous variability. For example, there may be hundreds of different types of traps or nets in use in a particular area. Further more, not all fishermen are equally skilled. Skills change continuously, and improvements in gear are constantly being introduced.
For example, if 15 boats, each fish fir 10 days, the fishing effort is 150 days.
