Importance of Aquaculture :
Serve as Source of Human Food :
Aquaculture supplies a quality source of
nutrition for an expanding population .Some medical authorities support the
benefits of fish & seafood in human diet.
Provides valuable non Food Products :
Some aquaculture crops provide valuable
products and by-products. Fine leather products are manufactured from eel skins &
alligator hides. Cultured pearls from oysters are used in making valuable jewelry.
Shells and skeleton parts may be incorporated into home & business decorations
.Educational programs may use frogs and other aquatic animals in the instructional
process. Lower quality, less –valuable shells may be used in paving roads or in
Contributes to Human Health Research :
By research, dietary supplements and other
ways. In research, certain animals are studied in an attempt to understand the human
body and how it functions, e.g. squid has been used in medical research since the early
1930s.Its nervous system has particular actions that are similar to certain functions of
the human nervous systems.
Creates Demand for Grain Crops:
The rations used to feed fish often require grain &
by-products of grain processing .Soybeans & corn are widely used in the feed. The
manufacturing of feed creates a demand for agricultural commodities, this should help
farmers who produce these ingredients of fish feed to find alternative markets for their
Creates Jobs & Economic Activity :
Jobs are created for thousands of individuals in
producing & marketing aqua crops.
International trade involves several aqua crops as well as captured fish and shellfish
.Currently, 80% of the shrimp and 65% of the fish consumed in U.S.
Revitalizes Rural Areas :
It has potential to revitalizes the rural areas .Many rural
areas have experienced a decline in agricultural profits. Some farmers have quit
farming traditional crops. A profitable aqua crop could stimulate the economy of an
Provides Recreation :
The sport fishing industry is increasingly using fee-lakes stocked
with cultured fish, particularly trout and catfish.
Improves Scenic Beauty:
Aquascaping is the term applied to using aquaculture to
add aesthetic beauty to an area .
Role of Animal Welfare :
Aquaculture producers are adopting certain
principles in their operations to insure animal welfare .Another concern of animal
welfarists has to do with the release of species in into environments where they are
not well adopted for growth. Placing trout in warm water streams is lethal, as they
are cold water fish. Other species thrive in warm water would not survive in cold
water. The welfare of pet fish in an aquarium is just as the welfare of fish on large
commercial fish farm.
Source of Nutrients :
Fish and some other types of seafood contain high levels
of Omega-3 fatty acids; thus, as a result, they have encouraged consumers to
include more fish in their diets.
The role of aqua crops in providing nutrients for both human and animal
consumption should increase, the by-products of processing many types of aqua
crops provide excellent sources of proteins for use in commercially prepared
