7. SPECIES DOMINANCE IN AQUACULTURE
Only a few species dominate global aquaculture
27 species/groups contribute 90% of finfish aquaculture
Major molluscs in aquaculture
Crassostrea sp. (Cupped oysters)
Ruditapes philippinarum (Japanese
carpet shell)
Pectinidae (Scallops)

14. INTENSIVE AQUACULTURE POLLUTES?
Intensive aquaculture
• consumes many inputs
• discharges many waste materials
Effluents discharged to the surrounding environment
Spread of diseases in the wild
Eutrophication
High BOD, COD
TAN, TN & TP
Increased sedimentation (TSS)
Increased salinization
Emission of GHGs?

15. INTENSIVE AQUACULTURE POLLUTES?
Intensive aquaculture
• consumes many inputs
• discharges many waste materials

16. ECOSYSTEM-BASED INTENSIVE FARMING SYSTEMS EMERGING
• RAS
• ZERO EFFLUENT SYSTEMS (IPRS)
• PLANT INTEGRATED FARMING SYSTEMS
• AQUAPONICS
• INTEGRATED MULTITROPHIC SYSTEMS
• BIOFLOC-BASED ZERO WATER EXCHANGE
• BIOMIMICRY SYSTEMS
• REDUCING PRODUCTION COST
• EFFICIENT WASTE RECYCLING

17. RAS Systems
These systems are based on
high technology, and
require high experience in
operating, and
understanding the meaning
of water quality and its
various measurements.

23. PLANT INTEGRATED FARMING SYSTEMS
Wheat in the winter
Rice with fish

24. PLANT INTEGRATED FARMING SYSTEMS

25. BIVALVES FOR WATER TREATMENT

26. Biofloc System
Bioflocs provide two critical services—treating wastes from feeding and providing nutrition from floc consumption.

27. BIOMIMICRY – MIMICKING NATURE

28. Antibiotics VS Probiotics
