Commercial fishing

Commercial fishing is an agricultural industry involved with the harvesting of a wide range of forms of edible marine life, including true fish, but also crustaceans such as shellfish, invertebrates such as squid and octopus, and seaweed. It is done in both fresh and salt water. It may be extended to include aquaculture, or "fish farming".

Since the resources involved can be regional or worldwide, there is a significant interest in Ffisheries monitoring surveillance and control to ensure sustained yields.
