Other types of cum fish farming

a.  Horticulture-fish farming:

• In one hectare of pond area, about 0.3 hectares of land are available, which can be used to cultivate banana, papaya, or citrus plants with low root systems.
• Fruit and vegetable leaves can be used as fish feed, pond water can be used for irrigation, and pond bottom soil can be used as a good fertilizer for the plantation.

b. Livestock-fish farming:

• Main stoked fishes include common carp, Chinese and indigenous major carp, and Nile tilapia.

c. Pig-fish farming:

• Here, supplementary fertilization and feeding are not required for fish.
• About 30% of the undigested feed is excreted in feces by pigs which serves as direct food for fishes.
• About 40-50 pigs are sufficient for fertilizing a one-hectare water area under fish culture.

d. Duck-fish farming:

• The droppings of the ducks act as a substitute for fish feed and pond fertilizers which accounts for 60% of the total input cost in fish culture.
• The ducks also eat fish enemies like aquatic insects, tadpoles, mollusks, aquatic weeds, etc. which don’t form food for fish.
• About 500-800 ducks are sufficient to fertilize one-hectare pond area.
• It is advisable to release fish fingerlings of more than 10 cm in size.
• The reported number of fingerlings in fish ponds varies from 7000-1000 per hectare.
• Silver carp, big head carp, or Catla along with common carp are ideal for duck-fish farming.

e. Poultry-fish farming:

• Fish provides fish meals, a protein-rich poultry feed, and poultry provides droppings which act as fertilizers for fish ponds.
• Approximately, 1200-1500 poultry birds are enough to serve the fertilizer needs of one hectare of fish culture pond.
• In general, 7000-10,000 fish are stocked in one-hectare pond.

f. Dairy-fish farming:

• 5-7 dairy cattle/buffalo rearing near a one-hectare fish pond is sufficient to fertilize it and also can give good remuneration prices.
• The cattle dung would be utilized for the fertilization of fish ponds and in return, the humus from these ponds would give a good fertilizer for growing fodder on the dikes.
