The live food fish trade is a global system
that links fishing communities with markets, across the continents.
of the fish are captured on coral reefs in the deep sea or
fresh water lakes such as L. Victoria in East Africa..
Most shrimps are sold frozen and are marketed
in different categories; the main factors for categorization
are presentation, grading, colour, and uniformity.
A fish market is a marketplace used for marketing
fish products. It can be dedicated to wholesale trade between
fishermen and fish merchants, or to the sale of seafood to
individual consumers, or to both. Retail fish markets, a type
of wet market, often sell street food as well.

Commercial fishing is the activity of capturing
fish and other seafood for commercial profit, mostly from
wild fisheries. It provides a large quantity of food to many
countries around the world, but those who practice it as an
industry must often pursue fish far into the ocean under adverse
conditions. Large scale commercial fishing is also known as
Commercial fishermen harvest a wide variety
of animals, ranging from tuna, cod and salmon to shrimp, krill,
lobster, clams, squid and crab, in various fisheries for these
Commercial fishing methods have become very
efficient using large nets and factory ships. Many new restrictions
are often integrated with varieties of fishing allocation
schemes (such as individual fishing quotas), and international
treaties that have sought to limit the fishing effort and,
sometimes, capture efficiency.
Fishing methods vary according to the region,
the species being fished for, and the technology available
to the fishermen. A commercial fishing enterprise may vary
from one man with a small boat with hand-casting nets or a
few pot traps, to a huge fleet of trawlers processing tons
of fish every day.
Commercial fishing gears today are surrounding
nets (e.g. purse seine), seine nets (e.g. beach seine), trawls
(e.g. bottom trawl), dredges, hooks and lines (e.g. long line
and handline), lift nets, gillnets, entangling nets and traps.
There are large and important fisheries worldwide
for various species of fish, mollusks and crustaceans. 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 tonnes
in 1999, with herring and sardines together providing a catch
of over 22 million metric tons in 1999. Many other species
as well are fished in smaller numbers.
A 2009 paper in Science estimates, for the
first time, the total world fish biomass as somewhere between
0.8 and 2.0 billion tonnes.
During 2000-2006, commercial fishing was
one of the most dangerous occupations in the United States,
with an average annual fatality rate of 115 deaths per 100,000
fishermen. The U.S. Coast Guard has primary jurisdiction over
the safety of the U.S. commercial fishing fleet, enforcing
regulations of the U.S. Commercial Fishing Industry Vessel
Safety Act of 1988 (CFIVSA). CFIVSA regulations focus primarily
on saving lives after the loss of a vessel and not on preventing
vessels from capsizing or sinking, falls overboard, or injuries
on deck. CFIVSA regulations require that commercial fishing
vessels carry various equipment (e.g., life rafts, radio beacons,
and immersion suits) depending on the size of the vessel and
the area in which it operates.
