Grenadier is a bottom dwelling, deepwater species caught mainly by trawl along the continental slope off the coasts of Tasmania and Victoria. It is soft and difficult to handle raw and has a short shelf life, so is often sold frozen. It is used for surimi (seafood extender) and in a wide range of products such as fish burgers. Much of the fish in the McDonald's Fillet-O-Fish Burger sold in Australia (and all of it in New Zealand) is Blue Grenadier. Australia also imports Blue Grenadier from New Zealand, usually as frozen fillets marketed as 'Hoki'. Also known as Blue Hake and Whiptail.
