Overview of and topical guide to fisheries
The following outline is provided as an overview of and topical guide to fisheries:
Fishery – entity engaged in raising or harvesting fish which is determined by some authority to be a fishery.[1] According to the UN Food and Agriculture Organization (FAO), a fishery is typically defined in terms of the "people involved, species or type of fish, area of water or seabed, method of fishing, class of boats, purpose of the activities or a combination of the foregoing features". The definition often includes a combination of fish and fishers in a region, the latter fishing for similar species with similar gear types.[2]
Fisheries science
Fisheries science – Fisheries science is the academic discipline of managing and understanding fisheries.
- Population dynamics of fisheries –
- Shifting baseline – the way significant changes to a system are measured against previous reference points, which themselves may represent significant changes from the original state of the system.
- Fish stock – Fish stocks are subpopulations of a particular species of fish, for which intrinsic parameters are the only significant factors in determining population dynamics, while extrinsic factors are considered to be insignificant.
- Fish mortality – Fish mortality is a term widely used in fisheries science that denotes the loss of fish from a stock through death.
- Condition index – The condition index in fish is a way to measure the overall health of a fish by comparing its weight with the typical weight of other fish of the same kind and of the same length.
- Stock assessment – Stock assessments provide fisheries managers with the information that is used in the regulation of a fish stock.
- Fish measurement – Fish measurement is the measuring of the length of individual fish and of various parts of their anatomy.
- Fish counter – Automatic fish counters are automatic devices for measuring the number of fish passing along a particular river in a particular period of time.
- Data storage tag – A data storage tag, also sometimes known as an archival tag, is a data logger that uses sensors to record data at predetermined intervals.
- Catch per unit effort – In fisheries and conservation biology, the catch per unit effort is an indirect measure of the abundance of a target species.

Wild fisheries science
Wild fishery – a fishery is an area with an associated fish or aquatic population which is harvested for its commercial value. Fisheries can be marine or freshwater. They can also be wild or farmed.

- Eel ladder – An eel ladder is type of fish ladder designed to help eels swim past barriers, such as dams and weirs or even natural barriers, to reach upriver feeding grounds.
- Fish ladder – A fish ladder, also known as a fishway, fish pass or fish steps, is a structure on or around artificial barriers to facilitate diadromous fishes' natural migration.
- Fish screen – A fish screen is designed to prevent fish from swimming or being drawn into an aqueduct, cooling water intake, dam or other diversion on a river, lake or waterway where water is taken for human use.
- Migration – Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres.
- Salmon run – The salmon run is the time when salmon, which have migrated from the ocean, swim to the upper reaches of rivers where they spawn on gravel beds.
- Sardine run – The sardine run of southern Africa occurs from May through July when billions of sardines – or more specifically the Southern African pilchard Sardinops sagax – spawn in the cool waters of the Agulhas Bank and move northward along the east coast of South Africa.
- Shoaling and schooling – In biology, any group of fish that stay together for social reasons are shoaling, and if the group is swimming in the same direction in a coordinated manner, they are schooling .
- Marine habitats – The sedimentologist Francis Shepard classified coasts as primary or secondary.
- Marine snow – In the deep ocean, marine snow is a continuous shower of mostly organic detritus falling from the upper layers of the water column.
- Water column – A water column is a conceptual column of water from surface to bottom sediments.
- Upwelling – Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-depleted surface water.[9]
- Humboldt current – The Humboldt Current, also known as the Peru Current, is a cold, low-salinity ocean current that flows north-westward along the west coast of South America from the southern tip of Chile to northern Peru.
