Advantages & Disadvantages of Biofloc Farming
Farmers involved in fish and shrimp production are inclining more
towards biofloc farming technology so that production can be
increased sustainably. But if not used properly researchers warn that the
method could be unsuitable.
The level of suspended solids in culture water needs to be maintained so
that there is no danger of diseases for shrimp and fish. There is a knowledge
gap in this technology which makes production management difficult. The idea to
use this technology rightly is that fish production and microbial proliferation
should occur in separate compartments.
Advantages and disadvantages
Pros
The flocs are protein-rich and helps to provide fish and shrimp with the
right amount of vitamins and phosphorous. Allowing the microbial flocs to
reproduce can improve water quality and can actually immobilize toxic nitrogen.
Farmers told that there is greater productivity using the system if they
compare it to conventional aquaculture techniques. This process can decrease
mortality rates, helps to increase larval growth and improve growth rates.
Using biofloc technology helps in improved water and land use rates. Since
the system relies on almost or near zero water exchange, the overall
environmental impact of production is low.
The cons
This technology requires a startup period and produce aren’t always
consistent between seasons. Since producers need to constantly mix and
ventilate culture water, energy costs could be higher.
Monitoring fish health is important as bioflocs may lead to increase in
the levels of suspended solids in the water.
What is biofloc best suited for?
Different shrimp species can thrive really well in biofloc culture.
Multiple researches have shown that shrimp as it is bottom-dwelling
species is best suited to biofloc production. Since the bacterial load that is
present in the water is changing at a constant rate, fish must be relatively
resistant to some environmental challenges. So it is said that the sensitive
species will not thrive with biofloc farming.
So here are the pros and cons for you to judge but since this process
effectively increases production and is reduce water pollution levels so this
method of farming can be used by the farmers.
