Keta salmon is the common market name for Oncorhynchus keta, more widely known as chum salmon. The name "keta" comes from the fish's species name, and its use is largely due to marketing efforts to rebrand the product and distance it from the less appealing historical name, "chum". While other salmon species, like sockeye or king, might steal the spotlight, keta is a powerhouse of accessible nutrition and culinary versatility that deserves a place in your kitchen.
Keta vs. Chum: Addressing the Name Change
Historically, chum salmon was sometimes called "dog salmon," a derogatory name that came from its historical use as food for sled dogs in Alaska. Another nickname, "silverbrite," reflects its appearance in the ocean. The use of the name keta is a modern effort to rebrand this affordable and widely available fish. It’s important to understand that when you buy keta, you are getting chum, and the flavor and texture will reflect this species' unique characteristics rather than those of a king or sockeye. The name "keta" itself is derived from the Russian language, which in turn borrowed it from the Evenki people of Siberia.
Where does the name "chum" come from?
The English name "chum" originates from the Chinook Jargon term tsəm, which means "spotted" or "marked," referring to the mottled appearance of spawning fish. Despite the negative connotations that developed around its colloquial name, keta or chum salmon has long been a staple in Indigenous communities, valued for its drying quality and for its roe.
Flavor Profile and Texture of Keta Salmon
Keta salmon is characterized by its mild, almost earthy, and less "fishy" flavor compared to other wild Pacific salmon. Its lower oil content gives it a firmer, leaner texture with medium-sized flakes. For those who prefer a subtler taste than the rich, robust flavor of sockeye or king, keta can be an excellent choice. Its lighter flavor also makes it a great canvas for a variety of marinades, rubs, and sauces. The flesh is paler in color, ranging from pale pink to orange, which is a visual indication of its lower fat content.

Health Benefits of Keta Salmon
Despite its lower fat content compared to king salmon, keta is still a highly nutritious fish. It is a lean source of high-quality protein and provides significant quantities of marine-derived omega-3 fatty acids, which are beneficial for brain and heart health. Keta also contains essential micronutrients such as Vitamin D, Vitamin B12, and selenium. Wild-caught salmon, including keta, generally have low mercury levels, making them a safe and healthy dietary choice.
Cooking with Keta Salmon
Because of its leaner, firmer texture, keta requires some adjustments in cooking to prevent it from drying out. Here are some cooking methods that work particularly well for this versatile fish:
- Grilling or Roasting: Its firm texture holds up well to high heat. Marinating the fish beforehand can help retain moisture and add flavor.
- Poaching: The gentle cooking method of poaching is ideal for keeping keta fillets moist and tender.
- Canning and Smoking: Due to its lower oil content and abundance, keta has long been a popular choice for preserving through smoking or canning.
- Fish Cakes and Burgers: Canned or flaked keta is an excellent base for making flavorful salmon cakes or burgers.
- Curries and Soups: The mild flavor of keta is complemented well by rich sauces and is perfect for adding to dishes like curries, chowders, or stir-fries.
The Prized Roe: Keta's True Delicacy
Beyond its flesh, keta salmon is highly valued for its large, juicy eggs, known as ikura in Japanese. Keta roe is considered some of the best for making this sushi treat, as the vibrant, golden-orange eggs have a delightful pop and a deep, savory flavor. Its value for roe is so significant that, historically, some fisheries targeted keta primarily for this product.
Sourcing and Sustainability

U.S. fisheries are sustainably managed and responsibly harvested, ensuring healthy population levels for the future.
