contributing to the agricultural exports and engaging
about fourteen million people in different activities.
• With diverse resources ranging from deep seas to
lakes in the mountains and more than 10% of the
global biodiversity in terms of fish and shellfish
species, the country has shown continuous and
sustained increments in fish production since
independence.

aquaculture as an important and highly productive agricultural
activity. Aquaculture refers to all forms of active culturing of
aquatic animals and plants, occurring in marine and fresh waters.
• Many Species of freshwater and marine organisms are being
cultivated as highly productive and nutritious crops for
consumption by humans.
• It is the rapid expansion of intensive, commercial aquaculture, It
Came in a decade after the Green Revolution (1970s; chemical-
based agriculture)
• Increase global food production and reduce widespread hunger.

18. Marine Cultivable
Biological resources• Crab resources
• In India, Scylla serrata and Scylla tranquebarica are
highly valued crabs and viable technologies have
been developed for fattening.
• Crab Fattening is practiced by few farmers in Kerala,
Karnataka and Tamil Nadu. Crab fattening involves
holding of large-sized crabs that have recently molted
(also known as “water crabs”) for 10-30 days until
they become hard.
18
19. Marine Cultivable Biological
resources• Shrimps
• A shrimp farm is an aquaculture business for the cultivation
of marine shrimp or prawns for human consumption.
• They play important roles in the foodchain and are important
food sources for larger animals from fish to whales. The
muscular tails of shrimp can be delicious to eat, and they are
widely caught and farmed for human consumption.
• Out of the total aquaculture production, brackishwater shrimp
production contributes about 5%. About 1, 50,000 ha are
under shrimp farming which is about 15% of the total
potential brackishwater area available in the country.

21. Marine Cultivable
Biological resources
• Seaweed resources
• Luxuriant growth of several species of green, brown
and red algae occur along the southeast coast of Tamil
Nadu, from Mandapam to Kanyakumari and Gulf of
Mannar islands, Gujarat coast, Lakshadweep, and
Andaman and Nicobar islands.
• Fairly rich seaweed beds are present in the surrounding
area of Mumbai, Ratnagiri, Karwar, Goa, Varkala,
Vizhinjam, and Visakhapatnam and in coastal lakes like
Chilka and Pulicat.
21
22. Marine Cultivable
Biological resources
• Seaweeds also occur in the estuaries and backwaters
of different maritime states.
• Seaweeds are useful for Manufacturing of Agar gel &
medicinal Purposes.
22
23. Site Selection Criteria for
Marine Aquaculture
• Availability of land in a continuous, suitably shaped plot of optimum
size with all facilities.
• The site should have assured & adequate water supply.
• Soil and water of the site must be suitable for fish culture.
• The site should be free from floods.
• The site should have good transport facilities and approach roads.
• The site should have electrical and telephone connections.
• The fish seed should be available easily and in plenty in that area.
• Marketing facilities should be available near the site.
• The site should be away from populated & polluted areas.
• The site should be connected to a drainage system.
• The fishermen or labour should be available near the site.

27. Financial Facilities in Marine
Aquaculture• National Fisheries Development Board (NFDB)
launches the shrimp & prawn insurance policy.
• In the Insurance Policy the following conditions are
passed,
Pollution from external source only
Poisoning
Malicious acts of third parties
Earthquake
Explosion / Implosion
Storm, tempest, cyclone, typhoon, Hurricane,
Tornado, flood, Inundation, volcanic eruption and or other
convulsions of nature.
Air Craft and other aerial devices or articles dropped there
from.
Impact, with any road vehicle.
Terrorism.
27
28. Financial Facilities in
Marine Aquaculture
• Credit facilities gives by the public sector institutions &
private sector institutions.
• Most of the credit flows are also from the private non-
institutional sector. i.e. merchants provide finance for
fishing & cultural operations in marine aquaculture.
• Marketing agents, professional money lenders advance
credit against securities of gold & agricultural
properties.
• Problems like multiple pond ownership, non
reorganization of land based activity, absence of long-
term leasing policy & non-assurance of seed supplies at
the appropriate time constrained access to credit. 28
29. Role of FAO
• Fish Technologists & Processors in developing
countries, to introduce appropriate technologies for
reducing fish spoilage.
• Fish processors in the fundamentals of quality, use of
ice, hygiene, etc.
• Improves handling practices on fish landing sites &
fish preservation methods.
• Improves fish consumption from low-value resources.
29
31. Future Prospects in Marine
Aquaculture
• Increasing demand: The increasing demand for fish
will require more production, and the supply from
capture fisheries is static.
• Emergence of the sector: Aquaculture has become
recognized as a growth sector of economic importance in
many countries and has attracted the attention of the
private and public sectors.
• Culture-based fisheries: Stocking of reservoirs and
enhancement/rehabilitation of fisheries will gain
importance with time, particularly as cost/benefit
problems are resolved.
31
32. Future Prospects in Marine
Aquaculture
• Growing awareness of sustainability needs:
• There is a rapidly growing awareness of the need
to ensure the sustainability of the sector in the
long term.
• Public debate involving all stakeholders, national
and international efforts to arrive at practical
guidelines for sustainable practices.
• Technical efforts to improve the sustainability of
some aquaculture systems, are positive responses
to challenges and will yield constructive results in
the medium and long term.
32
33. Future Prospects in Marine
Aquaculture
• Potential brackish water aquaculture area is widespread along
maritime states of India on both the east and west coasts.
• This area has increased consistently from 1991 till 1996 the year of
white spot viral disease outbreak, After that sustainability and
environmental issues have got the prime emphasis.
• As a result area covered by shrimp farms in the Coastal Regulatory
Zone (CRZ) along the entire coastline has remained almost the same
due to ban imposed by the Supreme Court of India in December, 1996
for construction
• The ban permitted shrimp farming only for new farms following
traditional cultural practices under monitoring and supervision of
Aquaculture Authority of India.The major problems faced by this
sector are availability of quality seed and cost-effective feed. In India
large scale brackishwater farming is limited to shrimp.
33
34. Development Prospects
• Marine Fish production from near shore waters has
reached almost a plateau &, at best, only marginal
increase is predicted from this zone.
• Objectives for future fisheries development include
enhancing fish production & productivity, generating
employment, improving socio-economic conditions of
fishers.
• Increasing marine products for export, & increasing per
capita availability of fish of about 11kg/yr.
• Developing policy & legal framework with required
safeguards for introduction of exotic varieties would
receive attention.
34
35. Future Needs
• India’s future fisheries development plans are aimed
at making substantial contributions to double food
production.
• The per capita availability & consumption of fish is to
be increased to a level of 11 kg/year.
• A number of schemes have been initiated by Central
Government for welfare of the fishing community.
• Improvements in database management &
development of linkages in all subsectors a
35
37. Conclusion
• India has bright scope in Marine Aquaculture sectors
scope lies in trade of various seeds throughout globe,
developing efforts in policies pertaining to seeds in India.
Increasing the Marketing and distribution system high
crop production growth.
• In Today’s era of developments in Marine Aquaculture
has proved to be a boon for Indian aqua culturist because
it increases the productivity. But still there is need for
expansion of aquaculture in India because it is restricted
to a few states only, so there is great scope for the other
fisheries based industries to enter into this sector.
• India has to develop approaches for the production of
Marine Aquaculture.
