1. Clinical Overview & Background

Biofloc Technology (BFT) — Complete Guide is a fundamental operational phase in successful aquaculture pond management.

Adhering to scientifically validated standard operating procedures ensures maximum survival rates, optimal Feed Conversion Ratios (FCR), and protects farm investments against bio-risks.

4. Step-by-Step Action Protocol

01

Carbon:Nitrogen ratio maintained at 15:1 by adding molasses/tapioca

02

Aeration is continuous and intense — minimum 30 HP/ha

03

No or minimal water exchange — only top-up for evaporation

04

Floc volume: 15–25 mL/L (measured by Imhoff cone); >50 mL/L is dangerous

05

Stocking density: 200–400 PL/m² for Vannamei

06

Saves 80–90% water compared to conventional systems

07

Initial investment higher but operational costs lower in long run

08

pH must be managed — add lime when pH drops below 7.5

5. Water Parameters & Dosage Benchmarks

Parameter / ItemRecommended ValueOperational Importance
Recommended Soil pH6.5 – 7.5Optimal soil microbial activity
Agricultural Lime (CaCO₃)200 kg / acreNeutralizes soil acidity
Plowing Depth15 – 20 cmExposes toxic black bottom sludge to oxygen

7. Frequently Asked Questions

Q: Why is this protocol necessary for high-density farming?

High stocking densities (> 50 PL/m²) create high biological oxygen demand and waste. Standard protocols maintain environmental stability.

Q: How often should this management process be repeated?

This should be executed prior to every stocking cycle during dry pond preparation.
