How solid waste put aquaculture systems at risk…RASTech

BFT is a problem in shrimp RAS.

Depending and managing one biological culture (the biofloc) is a risk as it can mean taking eye off the all important shrimp culture.

Hard to scale up – but great for where labour is cheaper.

BFT is bacterial brown water culture.

Green water culture is growing algae in pond.

Both are in pond or tank culture. No need to recirculate – so not even RAS really.

The RAS described talks about screen filtering but no mention about other technologies used in RAS – such as external biofilters (that are run with microbial films and flocs)…

All in all disappointed with article.
