the chemical used is meta bisulphate and is a preservative used to stop the heads going black as quik for the shop presentation, if u know the supplier like i do i get boxes of prawns that havnt been treated with meta, just have to eat them quicker which doesnt seem to be a problem

You would be shocked to see how prawns are grown and harvested in places like Thailand for instance.
They dig out a lagoon from the mangroves and use it until it becomes too diseased and polluted then move on down the coast a ways and make another.
To feed the prawns first they shanghai a crew and use them as slaves, a ship goes out to sea and drags the bottom collecting all manner of sea creatures and when they have enough they dump the load inside the lagoon to feed the prawns.
Raising tilapia is even worse, chicken pens directly above the fish tanks, fish eat the chicken 5hit then you eat the fish.

I wish you hadn't told me about thialand,those sweet little vanami's are my favourite prawns

Or do backyard marron - I started today.
But a 12mth wait for good size..... that's IF they thrive.......

Marron are difficult to get to work well. Ensure there are a lot of hiding spots for them, chuck in a heap of shadecloth and PVC pipe. Also make it difficult for them to climb out.

Worth the effort if you can tick all the boxes though

I never buy any sea food that is stamped imported from Thailand, China, Vietnam.................... Same for fruits and vegies. But maybe I am naive to believe the labels?
