Our Method

Biofloc Technology
— a living, working system.

BFT is a sustainable aquaculture method where beneficial microorganisms convert fish waste into live food — reducing cost, improving growth and protecting the environment.

Fish waste · Heterotrophic bacteria · Microbial floc · Supplementary feed protein — a closed nutrient loop

Zero Water Exchange

The same tank water circulates for months, drastically reducing groundwater consumption and effluent discharge.

Higher Biosecurity

An indoor controlled environment shields the fish from external pathogens and weather risks — no antibiotics needed.

Better Growth Performance

The microbial protein in the floc supplements commercial feed, improving FCR to 1:1.2 and reaching 300–350g harvest weight in 6 months.

HDPE Geomembrane Tanks

Durable, food-grade tanks (4–12 m diameter) with leak-proof liners — no soil contact, no contamination risk.

GIFT Tilapia Strain

Genetically Improved Farmed Tilapia developed over 10 generations — known for fast growth, high survival, good flesh quality and disease resistance.

Eco-Friendly Waste

Waste solids from tank cleaning are reused as organic crop fertiliser — closing the nutrient loop on the farm.
