FISH PRODUCTION

What is Fish

Production?

 Fish Production refers to the

output of fish by humans both from capture fisheries and aquaculture.

What are

Fisheries ?

Fisheries-a place where fish are reared for

commercial purposes.A fishing ground or area

where fish are caught.The occupation or

industry of catching or rearing fish.

What is Aquacult

ure?

Aquaculture- also known as aqua farming, is the farming of aquatic

organisms such as fish, crustaceans, mollusks and

aquatic plants. Aquaculture involves cultivating freshwater and

saltwater populations under controlled conditions, and can be

contrasted with commercial fishing, which is the harvesting of

wild fish.

Where must the fishing be

done?

Fishing can be done both in

marine fisheries and inland fisheries.

Lets talk about

marine &inland

fisheries!!!!

Marine fisheries – India’s marine fisheries include 7500 of coast line and

the deep seas beyond it. Popular marine fish variety’s include pomfret, mackerel, tuna, sardines and bombay duck. Yields are increased by locating large schools of fish in the open sea using satellites and echo sounders.

some marine of high economic value are also farmed in sea water this includes finned fishes like mullets , bhekti, and pearl spots, shellfish such as prawns,

mussels and oyeasters as well as seaweeds, oysters are also cultivated for

the pearl they make.

Inland fisheries-fresh water resources include canals, ponds, reservoirs and

rivers. Brackish water resources. where seawater and freshwater mix

together, such as estuaries and lagoons are also important fish

reservoirs. while capture fishing is also done in such inland water bodies

, where the yield is not that high. Most fish production in from these resources is through aquaculture.

A problem for which

solutions are being sought

today

Problem with such composite fish culture is that many of this fish breed only during monsoon. Even if fish seed is collected from the wild , it can be mixed up with that of other species

as well. So a major problem in fish farming is the lack of availability of

good quality of seed. To overcome this problem, ways have now been worked out to breed these fish I ponds using

hormonal stimulation. This has ensured the supply of pure fish seed in desired

quantities.
