Silvergray Rockfish



Silvergray Rockfish

Silvergrays can reach ages of 82 years or more, with both males and females reaching maturity between nine and 16 years of age. Peak periods for mating last from December to February, with normal larval release occurring from about April to August. Mostly found at depths of between 330 and 980 feet (100 and 300 m), in Alaska, juveniles and sub-adults have been found in depths as shallow as 55 feet (17 m). As they mature, however, adults form loose groups with other rockfish and can usuall be found within a few feet off the seafloor. Solitary individuals may sometimes be found resting on the bottom. Silvergrays only grow as long as 29 inches (73 cm), with a maximum published weight of just over 11 lbs (5 kg).

TASTING NOTES

  • Colour: Glistening bright white with a pinkish sheen. 
  • Texture: Very lean fillets with medium to firm texture and medium-sized flakes.
  • Flavour: Very mild, slightly sweet flavour.
  • Perfect serve: Given their mild flavour, Silvergrays lend themselves to a wide range of recipes – especially those with slightly richer ingredients. An excellent recipe to try is Silvergray Parmesan: fillets are lightly dusted with flour, dipped in egg, then coated with a breadcrumb and Parmesan cheese mixture. Oven-fry these fillets in a shallow pan with a couple of tablespoons of melted butter until the fish flakes easily when tested with a fork.
HOW TO CHOOSE A QUALITY SILVERGRAY ROCKFISH
Species Range

Silvergrays are perhaps the most humble rockfish in the Pacific. They are relatively slim compared to other species, have shorter spines on their back (their Latin name, brevispinis, means “short spine”) and are a dull silver-gray colour, for which they are named. Their only outstanding feature is a protruding lower jaw.

Besides their silvery or tan sides, Silvergrays are green to dark silvery gray on their backs and white to creamy colour on their bellies. The underside of their head and fins show some pinkish colouring. They range from the western Gulf of Alaska to central Baja California. Like most rockfish, their delicate fillets are lean, moist and tender with a mild sweet flavour. 

Fishing Methods

{'fisheries': [<License: Californian Groundfish by Bottom Trawl>], 'gear': <Gear: Bottom Trawl>}

Bottom Trawl

This fishery uses a large cone-shaped net that is dragged along the seafloor to catch fish. As the net is towed at low speed, hydrodynamic forces push two "otter boards" outwards opening the mouth of the net and capturing fish in its path.
