Aquaculture with Biofloc Technology
What is aquaculture? Also known as aquafarming, it involves the farming of aquatic organisms
like
fish,
mollusks,
crustaceans,
and
algae
under
controlled conditions as against commercial fishing, which is more harvest of wild fish.
One of the most widely consumed foods and a staple food in many
parts
of
the
world,
aquaculture
is
gaining
popularity
recently. The global fish production has risen to 177.8 million metric tons in 2019 from 148.1 million metric tons in 2010.

BFT in Aquaculture: An environmentally safe method, the BFT uses HDPE (highdensity polyethylene) geomembrane liners, enhances water quality
