Prawnfresh Plus will become a game changer for the domestic Gulf Shrimp industry. It dramatically reduces black spot, improves the appearance and extends retail shelf life for fresh, shell on shrimp up to seven days when the shrimp is properly refrigerated. After five days on ice in a refrigerated display case, the shrimp were still shiny, clear and looked like they had just come out of the sea.

I have been using Prawnfresh for over 3 years now, since the change our Prawns have looked a lot brighter and we have seen a 7% increase in yield. Prawnfresh more than pays for itself, its user friendly and doesn't do any damage to our dipping tank. All in all its a very good product to use. Our Prawn Processor Fraserburgh Seafood have also changed to Prawnfresh.
