A commercial fisherman typically does the following:
To plot the ship's course, commercial fishermen use compasses, charts, and electronic navigational equipment, including global positioning systems (GPS). They also use radar and sonar to avoid obstacles above and below the water and to find fish. Some commercial fishermen work in deep water on large fishing boats that are equipped for long stays at sea. Some process the fish they catch on board and prepare them for sale.
Other commercial fishermen work in shallow water on small boats that often have a crew of only one or two members. They might put nets across the mouths of rivers or inlets, or pots and traps for fish or shellfish, such as lobsters and crabs, or use dredges to gather other shellfish, such as oysters and scallops. A small portion of commercial fishing requires diving with diving suits or scuba gear. These divers use spears to catch fish and nets to gather shellfish, sea urchins, abalone, and sponges. Some fishermen harvest marine vegetation rather than fish. They use rakes and hoes to gather Irish moss and kelp. Although most fishermen work in commercial fishing, some in this occupation use their expertise in sport or recreational fishing.
The commercial fisherman plans and oversees the fishing operation, fish to be sought, location of the best fishing grounds, method of capture, duration of the trip, and sale of the catch. They direct the fishing operation and record daily activities in the ship’s log. Increasingly, they use the internet to bypass processors and sell fish directly to consumers, grocery stores, and restaurants.
Fishing operations are conducted under various environmental conditions, depending on the region, body of water, and kinds of fish sought. Storms, fog, and wind may hamper fishing vessels or cause them to suspend fishing operations and return to port. Sometimes the work environment can be unpleasant or dangerous.
