Shrimp RAS – exclusion or containment systems…..

In an ideal world bio-security means living in a bubble. That is fine and is the premise of the SPF term.

Current RAS shrimp grow out technologies however rely on exclusion biosecurity measures. Not completely living in a bubble at all.

Even in current RAS water effluents are allowed if abide to regulatory standards in location. Air effluent, as systems are run on positive air pressure (air/oxygen bubbled into water), are not controlled.

So now lets take a look from an external perspective NIMBY viewpoint…..positive pressure means that there seems to be some air escaping….and standards for water to waste means some discharge allowed. Hang on though…not really biosecure at all – maybe for protecting the crop but not for the environment where the facility is placed. Especially if growing exotics.

Containment RAS systems are such that there are no wastes at all. No water and no air. Nothing to the external environment except for the harvested protein……and even then that needs to be bio-securely delivered and cooked prior to eating.

Containment RAS therefore is a barrier to entry and exits technology whereas exclusion RAS technology (the current state of play) is just a barrier to entries.

Is containment RAS a possibility in shrimp growout?

What benefits are there? Better biosecurity for the environment? Diseases become secondary to growth? Other shrimp apart from vannamei become of interest?

Natural Shrimp USA with viral disease using US vannamei….

Blows a hole through the US SPF program….

Of interest is mode of entry of virus or is it omni-present just never expressed to detectable levels…..

….would have thought once ‘erradicated’ in system then exclusion and biosecurity works.

Gonna be interesting…
