Hoki
The hoki, blue grenadier, blue hake, New Zealand whiptail, whiptail or whiptail hake, Macruronus novaezelandiae, is a merlucciidae hake of the genus Macruronus, found around southern Australia, and New Zealand, at depths of between 10 and 1,000 m. Its length is between 60 and 120 cm.
The blue grenadier is similar in appearance to the rattails, with large eyes and a very elongate tapering body ending in a pointed tail consisting of the fusing of the second dorsal fin and the anal fin. There is a short spinous first dorsal fin. This fish-eating carnivore has a large mouth containing sharp pointed teeth used to catch and eat lanternfish, its main prey, but crustaceans and squid are also taken.
Its body colour is pale blue-green above, silver on the sides and belly, and the fins are darker.
Hoki is commonly available in supermarkets and is often used in pre-packaged fish fillets where you might expect to find cod. The hoki fish is also one of three components in McDonalds' Filet O'Fish commercial product for Canadian restaurants. The other two fish components are cod and Alaskan pollock.
