Spencer Gulf King Prawns have been added into the Wild South Seafood line because one of the owners earliest childhood memories was going crabbing with their Grandma off the jetty at Franklin Harbour. It was this jetty that the Spencer Gulf prawn fleet use to pull up at. These days they are all running out of Boston Bay and Port Lincoln just down the coast and round the corner a bit.
The Spencer Gulf prawn fishery is one of the best managed fisheries in Australia. The Spencer Gulf prawn fishery is MSC certified, which is kind of equivalent to the heart foundation tick for sustainability. It is good if you have it, but we should not necessarily judge those that don't as ipso facto bad.
The Spencer Gulf Prawn people have also known for quite some time that the best way to treat seafood that otherwise has a particularly short shelf life and is susceptible to toxins, is to snap freeze it at the source. All Spencer Gulf Prawns are frozen at the source and have been for a long time. Good on you Spencer Gulf for keepin' it fresh best!
Simple, green (uncooked/raw) really fresh prawns that have not been 'defrosted for convenience' but rather are still frozen when Wild South Seafood have bought them so they can decide when is convenient.
