Fisheries have license to fish in well-defined locations, type of fish to be caught and even methods of fishing to be used.
This is simply a fishing model that ensures that its' activities do not endanger the population in that fishing area. It ensures that the stock is healthy over an unlimited time period. It uses nondestructive methods to ensure that only the needed species and quantity are caught and also at rates that make fish easily re-populate. Sustainable fishing ensure that it the activities do not impact the ecosystem by removing their fish source, killing unwanted species, or destroying their habitats.
This, on the hand is any fishing practice that depletes the stock in the water, kills other species, destroys their physical environment and generally makes the entire fish species and others unhealthy. Examples of unsustainable fishing include pair trawling and bottom trawling.
