Healthful Benefits of Collagen in North Pacific Rockfish



Consuming natural collagen available in food like North Pacific rockfish may support and improve joint health. 
One of the 60 different species of North Pacific rockfish 

Our joints are comprised of intramuscular connective tissue made of collagen, water, and proteoglycans, with other noncollagenous proteins and glycoproteins present in lesser amounts. For 1000’s of years, before supplements, humans and other animals produced collagen for their joints and obtained the building blocks of collagen production through the food they ate.  Today, we can still eat food that contains both collagen and essential building blocks for collagen production.  North Pacific rockfish may be an ideal food resource for those building blocks and a direct source for absorbable collagen. Consult your physician before adding collagen supplements to your diet or eating specific foods to increase collagen.


At Otolith, superior taste and nutrition are both essential characteristics of sustainable seafood.  We value our rockfish for its environmentally responsible hook and line catch methods and for its excellence in flavor and healthfulness.  Otolith recommends specific cooking techniques for rockfish that provide the necessary heat to render rockfish’s connective tissue into gelatin while preserving the suppleness of the mild and delicate white fish fillet.  

According to WebMD http://www.webmd.com/osteoarthritis/guide/nutritional-supplements-osteoarthritis#1 our joint and tendon cartilage is comprised of mostly collagen and water.  Oregon State University characterizes the collagen levels of North Pacific Rockfish as containing more collagen that many other species of North Pacific fish. http://ir.library.oregonstate.edu/xmlui/handle/1957/27427 Collagen in rockfish is primarily found in their intramuscular connective tissue, and may present a unique culinary challenge to anyone unfamiliar with this scrumptious fish.

Otolith’s recipes compliment the nature of our ingredients.  Otolith’s rockfish recipes often include a dredging of egg wash and rice flour before searing rockfish in hot oil to lock in the flavor and nutrition of the fillet.  Seared coated fillets of rockfish can then be added to other ingredients used to make a sauce and continue cooking for up to 15 minutes while the beneficial collagen becomes indiscernible from the flakey juicy fillet. While other cooking methods are great for different fish, they can also yield rockfish that is tough in texture or dry in flavor.  When cooking rockfish, one should consider it important to avoid drying out the white fish fillet while achieving the necessary heat and doneness to soften the intramuscular connective tissue therein.
