Biofloc Tanks


Species suitable for Biofloc Culture
Major cultivable fish species in BFT
A basic factor in designing a biofloc system is the species to be cultured. Biofloc system works best with species that are able to derive some nutritional benefits from the direct consumption of floc. Biofloc system is most suitable for species that can tolerate high solids concentration in water and are generally tolerant of poor water quality. Some of the species that are suitable for BFT are:
Air breathing fish like Singhi (Heteropneustes fossilis), Magur (Clarias batrachus), Pabda (Ompok pabda), Anabas/Koi (Anabas testudineus), Pangasius (Pangasianodan hypophthalmus)
Non air-breathing fishes like Common Carp (Cyprinus carpio), Rohu (Labeo rohita), Tilapia (Oreochromis niloticus), Milkfish (Chanos chanos)
Shellfishes like Vannamei (Litopenaeus vannamei) and Tiger Shrimp (Penaeus monodon)


Use of land and water
Limited or zero water exchange system
Higher productivity (It enhances survival rate, growth performance, better feed conversion in the culture systems of fish).
Higher biosecurity.
Reduces water pollution and mitigate the risk of introduction and spread of pathogens
It reduces utilization of protein rich feed and cost of standard feed.
It reduces the pressure on capture fisheries i.e., use of cheaper food fish and trash fish for fish feed formulation.
