Trawling is an industrial method of fishing that involves pulling a fishing net, that is heavily weighted to keep it on the seafloor, through the water behind one or more boats. The net used for trawling is called a trawl. This principle requires netting bags which are towed through water to catch different species of fishes or sometimes targeted species. Trawls are often called towed gear or dragged gear.
A fishing trawler is a commercial fishing vessel designed to operate fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously.
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger.
Bottom trawling is trawling along the seafloor. It is also referred to as "dragging". The scientific community divides bottom trawling into benthic trawling and demersal trawling. Benthic trawling is towing a net at the very bottom of the ocean and demersal trawling is towing a net just above the benthic zone. Bottom trawling can be contrasted with midwater trawling, where a net is towed higher in the water column. Midwater trawling catches pelagic fish such as anchovies and mackerel, whereas bottom trawling targets both bottom-living fish (groundfish) and semi-pelagic species such as cod, squid, shrimp, and rockfish.
A Z-drive is a type of marine propulsion unit. Specifically, it is an azimuth thruster. The pod can rotate 360 degrees allowing for rapid changes in thrust direction and thus vessel direction. This eliminates the need for a conventional rudder.
The skipjack is a traditional fishing boat used on the Chesapeake Bay for oyster dredging. It is a sailboat which succeeded the bugeye as the chief oystering boat on the bay, and it remains in service due to laws restricting the use of powerboats in the Maryland state oyster fishery.
A fishing vessel is a boat or ship used to catch fish and other valuable nektonic aquatic animals in the sea, lake or river. Humans have used different kinds of surface vessels in commercial, artisanal and recreational fishing.
The bugeye is a type of sailboat developed in the Chesapeake Bay for oyster dredging. The predecessor of the skipjack, it was superseded by the latter as oyster harvests dropped.
Fishing techniques are methods for catching fish. The term may also be applied to methods for catching other aquatic animals such as molluscs and edible marine invertebrates.
The Chesapeake Bay Maritime Museum is located in St. Michaels, Maryland, United States and is home to a collection of Chesapeake Bay artifacts, exhibitions, and vessels. This 18-acre (73,000 m2) interactive museum was founded in 1965 on Navy Point, once a site of seafood packing houses, docks, and work boats. Today, the museum houses the world's largest collection of Chesapeake Bay boats and provides interactive exhibits in and around the 35 buildings which dot the campus. The museum also offers year-round educational seminars and workshops.

As with other countries, the 200 nautical miles (370 km) exclusive economic zone (EEZ) off the coast of the United States gives its fishing industry special fishing rights. It covers 11.4 million square kilometres, which is the second largest zone in the world, exceeding the land area of the United States.
The Stanley Norman is a Chesapeake Bay skipjack, built in 1902 by Otis Lloyd, Salisbury, Maryland. She is 48 feet 3 inches (14.71 m) in length overall with length on deck (LOD) OF 47.5 feet (14.5 m) two-sail bateau, or "V"-bottomed deadrise type of centerboard sloop. She has a beam of 16 feet (4.9 m), a depth of 4 feet (1.2 m) at the stern with the centerboard up, and a registered tonnage of 7 tons.
The Vantuna was a marine research vessel that operated in the Southern California Bight, from 1969 until 2007. It served as a tool for coastal research and was a unique platform for Occidental College students to gain first-hand experience conducting marine research operations. Scores of students who have worked on the Vantuna have gone on to have careers in marine science.

Ocean dredging was an oceanography technique introduced in the nineteenth century and developed by naturalist Edward Forbes. This form of dredging removes substrate and fauna specifically from the marine environment. Ocean dredging techniques were used on the HMS Challenger expeditions as a way to sample marine sediment and organisms.
An oyster buy-boat, also known as deck boat, is an approximately 40–90 foot long wooden boat with a large open deck which serviced oyster tongers and dredgers. Similar in function to sardine carriers, buy boats circulated among the harvesters collecting their catches, then delivered their loads to a wholesaler or oyster processing house. This spared the fishermen the task and its downtime, allowing them to catch more oysters. Buy-boats also bought seed oysters, or spat, for planting in oyster beds.
The Tilghman Watermen's Museum records the maritime traditions of the people of Tilghman Island and the unique way of life of the watermen who lived on the island. It is located on Tilghman Island, Talbot County, Maryland, United States.
