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".
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.
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]

[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 ...
