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".
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]
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.
This definition is widely accepted. [2] Maintaining a biological, social and economic system considers the health of the human ecosystem as well as the marine ecosystem. A fishery which rotates among multiple species can deplete individual stocks and still be sustainable so long as the ecosystem retains its intrinsic integrity. [8]
Wild fisheries are sometimes called capture fisheries. The aquatic life they support is not artificially controlled in any meaningful way and needs to be "captured" or fished. Wild fisheries exist primarily in the oceans, and particularly around coasts and continental shelves, but also exist in lakes and rivers.
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 ...
A fishery is an area with an associated fish or aquatic population which is harvested for its commercial value. Fisheries can be wild or farmed. Most of the world's wild fisheries are in the ocean. This article is an overview of ocean fisheries.
Also called rough fish. See also coarse fish. Trawling – is fishing with a large bag-like net, called a trawl, which is drawn along behind a boat called a trawler. The net can be dragged along the sea bottom in order to target demersal fish, or pulled through clear water in order to target pelagic fish.
