Aquaculture with Biofloc Technology.

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.
