Red Salmon – Definition, Characteristics, Behavior

Red salmon (Oncorhynchus nerka) or sockeye salmon is the second most abundant Pacific Ocean salmon. It has a significant bright, red-orange color. It also has an intense flavor. The red color is due to the consumption of krill. Red salmon turns into the deep red from their bright silver skin as they move upstream to spawn.

Pink Salmon – Definition, Characteristics, Behavior

Pink salmon (Oncorhynchus gorbusha) is the most abundant salmon in the Pacific Ocean. They have a light colored flesh and the flavor is also mild. They are sold either fresh, canned, smoked or frozen. Due to the presence of a distinctive hump in the back during spawning, the pink salmon is often called humpies or humpback salmon.

In general consideration, salmon is an oily fish rich in omega-3 fatty acids. This omega-3 comes from their diet, which includes small fish called herring, algae, and plankton. Some other types of salmon are chinook salmon/king salmon, coho salmon/silver salmon, salmo salar/Atlantic salmon, and chum salmon/silverbright salmon.

Similarities Between Red and Pink Salmon

• Red and pink salmon are two types of salmon fish that belong to the genus Oncorhynchus.
• They are anadromous fish that live in the ocean and enter freshwater to spawn.
• They live in the cold Pacific Ocean and the rivers draining to it. Both are caught in the wild.
• Both are good sources of calories, proteins, vitamin D, and omega-3 fatty acids including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Hence, consuming salmon is beneficial for heart attack, stroke as well as sudden cardiac death.
• Cooking and canning can reduce the coloration of both types of salmon.
• Harmful effects of industrial scale-fishing such as overfishing, habitat damage, pollution from salmon pens, and disease transfer from farmed salmons can affect the wild salmon population.
