Generally, a fishery is an entity engaged in raising or harvesting fish which is determined by some
authority to be a fishery. According to the 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.
A fishery may involve the capture of wild fish or raising fish through fish farming or
aquaculture. Directly or indirectly, the livelihood of over 500 million people in developing countries
depends on fisheries and aquaculture. Overfishing, including the taking of fish beyond sustainable
levels, is reducing fish stocks and employment in many world regions. If fisheries are poorly
managed, environmental impacts go unchecked. Unsustainable fishing practices put seafood resources
and fishing livelihoods at risk – the United Nations FAO estimates that 11 of the world's 15 major
fishing areas, and 69 percent of the world's major fish species, are in decline and in need of urgent
The term “fish”
In biology – the term fish is most strictly used to describe any animal with
a backbone that has gills throughout life and has limbs, if any, in the shape
of fins. Many types of aquatic animals commonly referred to as fish are not fish in
this strict sense; examples include shellfish, cuttlefish, starfish, crayfish and jellyfish.
In earlier times, even biologists did not make a distinction — sixteenth century
natural historians classified also seals, whales, amphibians, crocodiles,
even hippopotamuses, as well as a host of aquatic invertebrates, as fish.
True fish – The strict biological definition of a fish, above, is sometimes called a
true fish. True fish are also referred to as finfish or fin fish to distinguish them from
other aquatic life harvested in fisheries or aquaculture.
Fisheries are harvested for their value. They can be saltwater or freshwater, wild or farmed. Examples are
the salmon fishery of Alaska, the cod fishery off the Lofoten islands, the tuna fishery of the Eastern Pacific, or
the shrimp farm fisheries in China. Capture fisheries can be broadly classified as industrial scale, small-scale or
artisanal, and recreational.
Close to 90% of the world’s fishery catches come from oceans and seas, as opposed to inland waters. These marine
catches have remained relatively stable since the mid-nineties (between 80 and 86 million tons).
Most fisheries are wild fisheries, but farmed fisheries are increasing. Farming can occur in coastal areas, such as
with oyster farms, but more typically occur inland, in lakes, ponds, tanks and other enclosures.
There are species fisheries worldwide for finfish, mollusks, crustaceans and echinoderms, and by
extension, aquatic plants such as kelp. However, a very small number of species support the majority of the
world’s fisheries. Some of these species are herring, cod, anchovy, tuna, flounder, mullet, squid, shrimp,
salmon, crab, lobster, oyster and scallops. All except these last four provided a worldwide catch of well over
a million tons in 1999, with herring and sardines together providing a harvest of over 22 million metric tons in
1999. Many other species are harvested in smaller numbers.
Overfishing is the act whereby fish stocks are depleted to unacceptable levels, regardless of
water body size. Low biological growth rates and critically low biomass levels result from
overfishing. For example, overfishing of sharks has led to the upset of entire marine
The ability of a fishery to recover from overfishing depends on whether the ecosystem’s
conditions are suitable for the recovery. Dramatic changes in species composition can result in
an ecosystem shift, where other equilibrium energy flows involve species compositions
different from those that had been present before the depletion of the original fish stock. For
example, once trout have been overfished, carp might take over in a way that makes it
impossible for the trout to re-establish a breeding population.
