Fish Farming and Aquaculture
farming is the principal form of aquaculture, while
other methods may fall under mariculture. Fish farming involves
raising fish commercially in tanks or enclosures, usually
A facility that releases juvenile fish into the wild for recreational
fishing or to supplement a species' natural numbers.
The most important fish species raised by fish farms are,
in order, salmon, carp, tilapia, catfish and cod.
Increasing demands on wild fisheries by commercial
fishing has caused widespread overfishing. Fish farming offers
an alternative solution to the increasing market demand for
fish and fish protein.
Aquaculture is the farming
of freshwater and saltwater organisms such as finfish, crustaceans
and aquatic plants. Also known as aquafarming, aquaculture
involves cultivating aquatic populations under controlled
conditions, and can be contrasted with commercial fishing,
which is the harvesting of wild fish.Commercial aquaculture
supplies one half of the fish and shellfish that is directly
consumed by humans.
Major categories of fish farms
There are two kinds of aquaculture:
aquaculture based on local photosynthetical production
aquaculture, in which the fish are fed with external
food supply. The management of these two kinds of aquaculture
systems are completely different.
Specific types of fish farms
Within intensive and extensive aquaculture methods there
are numerous specific types of fish farms, each has benefits
and applications unique to its design.

Expanding Sustainable Aquaculture
According to the U.N. Food and Agriculture
Organization, aquaculture provided 43% of the total food supply
of fish in 2004. Analysis suggests that by 2020, almost half
of all fish and other aquatic products in consumer markets
worldwide will be farmed.
Many coastal fisheries are thought to be
at or near their productive capacity. But aquaculture production
overall has been increasing by 6.6% a year, and is expected
to continue growing.
This dynamic growth can be tapped in ways
that reduce poverty while increasing global food supply. Whether
that happens, however, depends critically on where and how
aquaculture is implemented.
WorldFish Center is at the forefront of the
development of sustainable aquaculture technologies. The methods,
particularly well adapted for use by small-scale producers
in developing countries, are making it possible for a growing
number of the world’s poorest people to better feed
and support themselves.
Under the right conditions, this kind of
aquaculture improves human well-being in a number of ways
that support the Millennium Development Goals (MDGs). Direct
benefits include greater food security, improved nutrition,
supplemental income, and livelihood options. The approach
can bring significant indirect benefits as well, by contributing
to economic growth, easing pressure on increasingly scarce
stocks of fish in the wild, improving health and empowering
