5. FEED AND FERTILIZER DEMAND IN FISH FARMING
100kg herbivorous sIuesµA
100kg filter feeder
50kg omnivorous

4,500 kg
Pig manure
150 kg
Grains
250kg fish
(net weight)
1,500 kg
Aquatic grass
1,000 kg
Vegetable

6. THE TYPE OF ARTIFICIAL FEEDS IN AQUACULTURE
Aquatic and terrestrial plants (elephant grass, duckweed)
Aquatic animals and terrestrial-based live feeds (snail, earth worm)
Plant processing by-products (rice bran,…)
Animal processing by-products (fish meal,…)
Industrial wastes (wine and beer manufacturing)
Formulated feeds (composed several materials )
Commercial feeds (pellet)

7. NUTRITIONAL VALUE
-Palatability
-Digestibility
-Nutritional composition
FEED CHOICE
-Cost
-Availability
The system is suitable for both large scale and small scale fish farming
-Energy saving
-Money saving
-Reduce cost
-Increase profit

8. THE MAIN SYSTEMS OF INTEGRATED FISH FARMING
The system of fish-crop integration (dyke-pond)
The system of fish-livestock/poultry integration
The system of fish-livestock/poultry-crop integration
The system of Multi-level utilization

The mean thickness is about cm/yr or m3/ha/yr
(earthen pond with 7,500kg/ha fish production)

13. THE EFFECT OF POND SILT ON FISH POND
As a kind of fertilizer for fishpond water
Consume dissolved oxygen in the fishpond, reduce pH and create toxicity material (e.g. NH3, H2S, CH4)
Hiding the pathogens and parasite of fish disease
Reducing the carry capacity of fishpond

14. THE EFFECT OF POND SILT ON CROP CULTIVATION
Increases the thickness of the cultivation land layer
Improves the soil’s particle structure, strengthens its ability to absorb N, P and K and improves the soil's capacity to hold water.
Slow-acting fertilizer, which is beneficial to later crops
Increase the yield of crop.
