Fisheries science is the academic discipline of managing and understanding fisheries. [1] It is a multidisciplinary science, which draws on the disciplines of limnology, oceanography, freshwater biology, marine biology, meteorology, conservation, ecology, population dynamics, economics, statistics, decision analysis, management, and many others in an attempt to provide an integrated picture of ...
According to the FAO, "...a fishery is an activity leading to harvesting of fish.It may involve capture of wild fish or raising of fish through aquaculture." It 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".
Fisheries management – Fisheries management draws on fisheries science in order to find ways to protect fishery resources so sustainable exploitation is possible. sustainability; conservation – Marine conservation, also known as marine resources conservation, is the protection and preservation of ecosystems in oceans and seas.
An example in fisheries is the length of fish in a fishery, which might show two or more modes or peaks reflecting fish of different ages or species. Biodiversity – is the variation of life forms within an area. In the context of fisheries the number and variety of organisms found within a fishery.
Managing fisheries is about managing people and businesses, and not about managing fish. Fisheries are managed by regulating the actions of people. [22] If fisheries management is to be successful, then associated human factors, such as the reactions of anglers and harvesters, are of key importance, and need to be understood. [23] [24]
Virtual population analysis (VPA) is a cohort modeling technique commonly used in fisheries science for reconstructing historical fish numbers at age using information on death of individuals each year. This death is usually partitioned into catch by fisheries and natural mortality. VPA is virtual in the sense that the population size is not ...

In fisheries science and ecology, stock assessment is an important tool in fisheries management. In particular, to ensure continued, healthy, fish stocks, measurements of the Spawning Stock Biomass (the stock population capable of reproducing) allows sensible conservation strategies to be developed and maintained through the application of ...
