differnet fish forming systems commonly used in the world for rearing of aquatic organisms from fry, fingerling stage to adults at morketable size in selected aquatic ecosystem(pond, reservoir, tank, raceways, pens, cages, integration with other synergetic crops) site for cultivable desired aquatic fish species.
Fish 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 for food. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species used in fish farming are carp, salmon, tilapia and catfish.
There is an increasing demand for fish and fish protein, which has resulted in widespread overfishing in wild fisheries. Fish farming offers fish marketers another source. However, farming carnivorous fish, such as salmon, does not always reduce pressure on wild fisheries, since carnivorous farmed fish are usually fed fishmeal and fish oil extracted from wild forage fish. The global returns for fish farming recorded by the FAO in 2008 totalled 33.8 million tonnes worth about $US 60 billion.
Specific types of fish farms[edit source | editbeta]
Within intensive and extensive aquaculture methods, there are numerous specific types of fish farms; each has benefits and applications unique to its design.
Cage system[edit source | editbeta]
Giant gourami is often raised in cages in central Thailand
Fish cages are placed in lakes, bayous, ponds, rivers or oceans to contain and protect fish until they can be harvested. The method is also called "off-shore cultivation[7] " when the cages are placed in the sea. They can be constructed of a wide variety of components. Fish are stocked in cages, artificially fed, and harvested when they reach market size. A few advantages of fish farming with cages are that many types of waters can be used (rivers, lakes, filled quarries, etc.), many types of fish can be raised, and fish farming can co-exist with sport fishing and other water uses. Cage farming of fishes in open seas is also gaining popularity. Concerns of disease, poaching, poor water quality, etc., lead some to believe that in general, pond systems are easier to manage and simpler to start. Also, past occurrences of cage-failures leading to escapes, have raised concern regarding the culture of non-native fish species in open-water cages. Even though the cage-industry has made numerous technological advances in cage construction in recent years, the concern for escapes remains valid.
Main article: Copper alloys in aquaculture
Recently, copper alloys have become important netting materials in aquaculture. Copper alloys are antimicrobial, that is, they destroy bacteria, viruses, fungi, algae, and other microbes. In the marine environment, the antimicrobial/algaecidal properties of copper alloys prevent biofouling, which can briefly be described as the undesirable accumulation, adhesion, and growth of microorganisms, plants, algae, tube worms, barnacles, mollusks, and other organisms.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

2. EXTENSIVE FISH FARMING
SYSTEM
• systems use low stocking densities (e.g., 5 000-10
000 shrimp post larvae (PL)/ha/crop) and no
supplemental feeding, although fertilization may be
done to stimulate the growth and production of
natural food in the water
3. SEMI-INTENSIVE FISH FARMING
SYSTEM
• Semi-intensive farming systems account for about
70% of fish and crustacean aquaculture production
in the tropics, employing semi-intensive feeding
methods ranging from the use of low-cost pond
fertilization tech- niques to high-cost complete diet
feeding strategies.
4. • INTENSIVE FISH FARMING
SYSTEM
• An intensive fish farming system is the well-
managed form of fish farming, in which all attempts
are made to achieve maximum production of fish
from a minimum quantity of water. This system
involves small ponds/tanks/raceways with very high
stocking density (10-50 fish/m3 of water). Fish are
fed wholly formulated feed.
5. INTEGRATED AQUACULTURE
SYSTEM
• Integrated fish farming combines fish, swine,
poultry, and vegetable production. Chicken coops
and pens for pigs and ducks can be constructed on
the dikes or above the ponds. Fresh animal manure
thus enters the pond directly, hastening the growth
of natural food organisms for the fish being
cultured in the pond.
6. KINDS OF BEING CULTURED AS
MEANS OF LIVELIHOOD
• Milkfish and Nile tilapia are the major fishes now
produced but groupers, sea bass, rabbit fish, red
snappers, carps, and catfishes are grown by some
farmers.
7. WAYS TO PREVENT POSSIBLE
HAZARDS BROUGHT ABOUT BY
CULTURING FISH
• USe of proper site pre evaluatiocondition
procedure.
• Good construction practices
• Lower stacking rate and commercial feeding
rate
• Proper management Technique
• Maintaining good water quality conditionsa
• Keeping the culture facility clean and Well
organized
• Adoption of sustainable Culture techniques
8. MILK FISH
• Milkfish is the national fish
of Philippines and it is
known locally as "bangus"
Milkfish is a delectable fish
which grows fast and can
tolerate a wide range of
salinity.
9. TILAPIA
Tilapia is a
good fish for
Culture, it can
be breed in
ponds, cages,
or fish pens. If
