Biofloc is one type of fish farming method and earn more money as compared other business. In that for farming you can grow different types of fish varieties. Biofloc is a profitable method of fish farming worldwide. principle of this technique is that recycle nutrient. This system helps up to 4 to 5 lac rupees in year with only one acre area of farming.
Based on some interviews with farmer regarding biofloc farming we get some positive reply from all of them.
They gives idea how to start biofloc farming and Everything You Need ,with minimum cost and earn more profit.
However you start farming you can follow below steps.
How to start biofloc farming we discuss step by step
Tank or pond setup in farm
you plan to start farming you need to set tank or pond.
It’s best to start with lined ponds, concrete ponds or Indore ponds.
Indoor ponds
Provide better experience in most tropical countries, having big advantages, less affected by heavy rainfall, alkalinity and PH value of water.
In that system, fish won’t grow sufficiently.
Because of Absence of Sunlight and natural air.
will cause effect on farming.
Outdoor ponds
open space Tank it provide better experience.
Outdoor pond system never easily affected by heavy rainfall in monsoon condition.
Alkalinity, and PH value of water.
After That cover ponds is best option for farmer.
Types of tank
TCLPVC is biofloc fish farming tank easy available in market.
Approximate 5 to 7 year tank life.
It’s available at market 5000 litreTo 10000 litre insize.
Available sizes 4 metre ,10000 litre liner tank which having a better life.
Supplier provide installation and maintenance of tank.
Approximate cost of 10,000 to 12,000 for per tank.
Aeration system set up
After completing the installation of pond or tank, next do the work on aeration system set up.
In Biofolic fish farming system required oxygen level and to keep soil from settling.
Water without movement will rapidly lose oxygen level.
It causes anaerobic zone in pond.
Anaerobic zone release large amount of methane and ammonia in to water.
To prevent this situation you need to set up pedal wheel aerators in pond, and tank raceway system much more important.
Therefore In biofolic system required 6 to 7 mg of oxygen per litre at every hours.
Above all steps are used to biofolic farming is very important.
However you start farming you can follow above steps.
fish selection
Biofloc fish farming technique is most reliable and profitable method of farming, this technique provides you the best utilization of land and water resources in farm.
Whenever you start cultivate fish like catla,rohu,common carp, silver carp, mrigal, and much more varieties depends on your local market.
It required 6 to 7 month duration required to cultivation for fish farming.
catla and rohu are evergreen and most preferred by consumers in market.
If you select silver carp it gives twice the yield of catla and roha,
But silver corp having poor shelf life.
Carbon source balancing
Whenever start the farming cycle you need to prevent Ammonia peak level.
Therefore This type of situation generally originate from the availability nitrogen in feeds.
Controlling Ammonia peak at later stage of production is very important. Because of This stage may be repeated in biofloc fish farming.
However you are able to control the ammonia peak this is one of the hardest step successful implementing biofolic fish farming principal.
Biofloc growth
If you want to monitor the growth of biofloc can be done by using a cone shaped Baker.
You can collect water sample at it depth of 20 cm to 25 cm.
Preferly it can be done by late morning.
Biofloc growth very important because, farming estimated earning totally depends on the weight of fish and market situation.
Availability of natural light, fresh air, proper aeration system, climatic condition all of the above things are suitable, and readily available of carbon source your biofloc number should be start to multiply quickly.
Control water parameter and monitoring
In parameter section we generally observed amount of air high respiration rate increased by significantly due to installation of aeration system in biofloc.
Requirement of respiration rate near about 6 milligram per litre per hour.
Sometimes heterotrophic bacteria start producing ammonia due to low oxygen level in the environment.
Generally lack of oxygen these types of situation causes any power failure and failure of aeration system.
You need to to fix the some alternate sources of power backup.
This types situation generally create in rural areas where at farming operation Run.
Solar system, diesel generator, and also paddle wheel aerator available at market with solar panel.
Whenever you monitoring the water parameter especially check dissolved oxygen and Ammonia level.
Harvesting and cleaning
The most important step is harvesting and cleaning.
Cleaning process is very important in biofloc system.
It increases the growth rate of survival and improve operating profitability.
Don’t forget and underestimate,the proper cleaning and preparation of pond setup raceway.
Research has also indicated that the over time,heavy metals can built of the cultural water.
Which can accumulate in your stock making it unsuitable for human consumption.
All farmer we are highly recommended to cleanup pond or tank before starting your next profitable batch.
That’s why the clean is very important in every process at every moment when you are doing biofloc production in worldwide.
Keep in mind well cleaning and housekeeping it will increase your profit.
