5. Definition
According to IFOAM OI "Organic
aquaculture is a developing sector
involving farmers worldwide producing a
wide range of aquatic species – including
fish, seaweeds and bivalves – in line with
organic principles."

6. AIMS

7. CONVENTIONAL vs
ORGANIC
AQUACULTURE

8. Type of system
Conventional Organic
Practiced in open system Practiced in closed
system

9. GMOs(genetically modified organism)
conventional organic
GMOs are used to get
higher output regardless
of their impact.
No GMOs are used,
instead indigenous and if
required exotic species are
used.

10. Diseases Management
Conventional Organic
Use of chemicals to cleanse
the system and use of anti-
biotics to control diseases.
Use physical, mechanical
and biological means to
control diseases.
Self-cleaning Tank

11. Feeds
Conventional Organics
Prepared synthetically by
adding one or more feed
additive
Derived from organic
sources

12. Biosecurity
Conventional Organic
Less or no emphasis on
biosecurity
Emphasis on biosecurity

13. Nutrient & water recycle
Conventional Organic
No nutrient recycle &
water recycle is done.
Sludge generated is
incorporated into other systems
or converted to manure. Water
too is recycled.

14. How it is achieved??

15. PRINCIPLES
1. Absence of GMOs (genetically
modified organisms) in stocks and
feed prime material.

16. 2..Limitation of stocking density

17. 3.Origin of vegetal feed and fertilizer from
certified organic agriculture, no artificial
feed ingredients & Keep feed input
relatively constant

18. 4.Restriction on energy
consumption
Eating feed and using oxygen results in fish growth and
excretion of waste Products such as carbon dioxide ,
ammonia and faeces

19. 5. Ensure Good Aeration

20. 6. Remove Solids

21. Factors affecting fish development

22. Recirculation Aquaculture
System (RAS)

23. PARTS OF RAS SYSTEM
1. Grow out tank /rearing tank/culture
tank
2. Solid removal
3. Bio-filters/bio-filtration
4. Aeration/Oxygenator
5. Disinfection
6. Pump/re-circulator

26. 1. Culture Tanks
Circular tank , D-ended Raceway and raceway type

28. Particle size Removed by
Settable solids Settlers, settle out in
water within one hour
Medium sized solids Clarifier, mechanical
separator, swirl
separator
Suspended soilds These solids do not
settle, bead or sand
filter
Three kind of solid particles:-
2.Solid removal

31. 3.Biofiltration
• It is process of removing dissolved metabolic
waste products (ammonia and nitrite) from
the water.
• It requires the water to pass through filters
that have live bacteria living in them.
• The filters are usually filled with small media
with a large surface area where the bacteria
can grow.
• The effectiveness of this process is measured
in terms of surface area.

34. The oxidation that converts the nitrites
to nitrates follows following reaction:

35. 4. Oxygenation

37. 5.Disinfection

38. Non - water
submersible/dry
pump
Water
submersible/wet
pump
6.Pump/ re-circulator

39. Components of RAS
Rotating drum filter

40. Foam fractionator
Ozone diffuser UV light generator

41. FISH
SPECIES

42. CARPS

45. AIR BREATHING FISHES

48. CRUSTACEAN

49. COLDWATER FISHES

52. Feeds
Classification on the basis of density:-
• Floaters- that float on the surface of water
• Heavier-that drown into the pool
• Semi floats -that drowns slowly
Different formulations:-
 Pellets
 Capsule
 Hard feed
 Soft feeds

54. Different sources for feed stuff
• Plant based

55. • Animal based

56. • Insect based

57. Locusts as fish feed

58. • Fish based

59. Different ways of
integrating OA..

60. 1.AQUAPONICS

61. Aquaponics consists of two main parts :
Aquaculture part
For raising aquatic
animal
 Hydroponics part
For growing plants

62. How Aquaponics
Works??????

64. The three main live
components are :-
1.Plants
2.Fish
3. Bacteria
Live Components

65. PROFITABLE PLANTS FOR AQUAPONIC-
Okra
Tomato
Cantaloupe
Bell Pepper

67. University of Virgin Islands(USA)

TOTAL COST Rs39910
TOTAL RETURN 80850+ 8000= 88850
NET RETURN 88850-39910= RS.48940

71. Economic Analysis of Paddy cum fish
culture
No of fish per hectare 7500
Mortality rate 10%
Rate of fish Rs.3/fish
Total cost of fish 7500×3=22500
Pond preparation cost Rs 10000
Feed cost Rs 20000
Management charge Rs 5000/labour/month(2
labour required for 4 months)
Total cost 22500+10000+20000+40000=R
