Building commercially successful aquaponics systems in India
Transcript of Building commercially successful aquaponics systems in India
Now aquaponics is set to bridge the nutrition divide. Constructing the infrastructure Step A Step B Framework for commercial aquaponics Erect the tank, free from any pre-use contaminants, to breed the fish
Commercial sizes: 1000/4000 litres, about one m water depth, 1.2 m high. For hobbyists even 20 litres is OK
Fill with fresh water, free of chlorine, chemicals, or antibiotics
Instal auto feeding system (optional)
Cover tank to protect from dust; allow some light
Where feasible bury the tank in the ground and maintain 25-30 deg C Erect rafts, towers, gravel beds, channels for planting the veggies/greens
Protect from cold Step D Location
Plants Purpose Landscaping
Sell fish and veggies
Social cause projects A clean container
Air blowing system
Water circulation system
Water filtering system
Fish feed Aquaponics essentials International Congress on Urban Green Spaces Green Cities, Green Minds Step C Arrange seedlings and fingerlings Pot the seedlings and release the fingerlings Keep circulating the water
Maintain oxygen levels
Maintain pH between 7 and 7.5
Feed the fish 2-4% of body weight/day
Use floating or sinking fish feeds as per species
Avoid shocks to fish such as high ammonia spikes or low oxygen levels
Keep fish tank clean, remove solid waste periodically
Monitor fish growth
Keep fish wt below 30 kgs per 1000 litres Step E Typical commercials Fish tank cost: Rs 5-10 per litre
Water pump: Rs. 1,500 50W, 220 VAC
Air pump: Rs. 1,000/- 220 VAC
Grow beds: < Rs. 5 per litre
Fish production: 50 kgs/1000 litres tank/year
Greens: 300 kgs/1000 litres tank/year
Fish feed cost: Rs. 20-30/Kg.
