Biofloc Technology (BFT) in the Prawn Farming…lots of catch all culture type links.

BFT as a production system for intensification has been shown limiting.

BFT being defined as any shrimp culture that needs a sedimentation (Imhoff) cone to measure biofloc of system.

Above 5kg/cbm super-intensive shrimp culture systems are moving away from BFT to RAS ( forget all the hybrid hype).

Microbially managed systems use biofilters and other techniques but don’t use or measure biofloc (no need the Imhoff cone)his article confuses BFT culture with super-intensive, RAS and microbial management systems.

This article opinion confuses BFT culture with super-intensive, RAS and microbial management systems.

Prawn scale change…take note on a per cycle level..

What used to be called intensive shrimp farming (4MT/ha) is now considered semi-intensive.

Intensive farming is now anything up to 50MT/hectare or around 5kg/cbm. The biofloc range limitation.

Above 5kg one is now talking super-intensive – up to 15kg/cbm.

Above 15kg/cbm then one is into the realm of hyper-intensive…or even ridiculous-intensive (until it happens time after time)…

In Prawnmaster’s private Shrimp Lab in 2016…

Now implementation in vannamei.eu commercial shrimp RAS – a global first.
