Grizzly bears are omnivorous animals that feed on a wide variety of foods across North America. One of their favorite foods is salmon. During the annual salmon run, grizzly bears congregate along Alaskan rivers and streams to gorge themselves on these nutrient-rich fish.
Why Grizzly Bears Love Salmon
Salmon provide an abundant source of protein and fat for grizzly bears prior to hibernation in the winter months Here are some key reasons why grizzly bears eat salmon
-
High calorie count – A 4-pound salmon can provide a grizzly bear with up to 4,000 calories. They need to build up fat reserves to survive the winter when food is scarce.
-
Nutrient content – Salmon are rich in protein, omega-3 fatty acids, vitamins, and minerals This helps bears maintain their strength and health
-
Readily available – Salmon migrate in massive numbers along rivers and streams, providing easy access to grizzlies. During peak spawning season, bears can catch dozens of fish daily.
-
Taste – Grizzlies likely enjoy the rich, fatty taste of salmon compared to vegetation or other prey. The high fat content makes salmon a prize catch.
Grizzly Bear Salmon Feeding Habits
Grizzly bears employ various fishing techniques to catch salmon, including:
-
Waiting patiently at stream bends and waterfalls for salmon to swim near. They quickly snatch fish from the water with their sharp claws.
-
Slapping the water with their paws to stun fish before biting into them.
-
Scooping salmon up in their mouth as the fish jump upstream.
-
Catching leaping salmon directly in their jaws as they swim upstream to spawning grounds.
A grizzly bear can consume 10-20 salmon per day on average, and up to 40-50 fish during peak salmon runs. They focus on the most nutrient-dense parts of the fish: the brain, eggs, and skin. After gorging, bears typically move away from the streams to digest their meal and allow room for more fish to pass.
Best Places to See Grizzly Bears Catching Salmon
Some of the top spots to witness grizzly bears feasting on salmon include:
-
Katmai National Park, Alaska – Famous Brooks Falls is a top gathering spot for dozens of bears to catch salmon swimming upstream.
-
McNeil River State Game Sanctuary, Alaska – Up to 144 bears congregate along the river during July salmon runs.
-
Lake Clark National Park, Alaska – Bears fish for salmon along the shorelines of Chinitna Bay.
-
Glacier National Park, Montana – Grizzlies forage for spawning trout and salmon along streams and lakes.
Guided eco-tours offer once-in-a-lifetime opportunities to safely view bears fishing for salmon in these spectacular wilderness settings. Seeing a grizzly bear catching salmon with its immense strength and speed is an unforgettable wildlife encounter.
Threats Facing Grizzly Bears and Salmon
While salmon provide sustenance for grizzlies, both species face numerous threats in the wild:
-
Habitat loss from human development, logging, mining, and agriculture reduces bear and salmon populations.
-
Overfishing of salmon stocks depletes this vital food source for grizzlies.
-
Climate change is warming rivers, altering salmon migration patterns, and causing low stream flows. This makes it harder for bears to fish.
-
Poaching and hunting remain dangers, despite grizzly bears being listed as a threatened species since 1975.
Conservation efforts are underway to protect critical grizzly bear and salmon habitats. Responsible eco-tourism also helps highlight the ecological significance of their food chain relationship for sustaining Alaskan wilderness areas. Seeing bears catch salmon is a memorable reminder of the beauty and fragility of these ecosystems.
Diet Of Grizzly Bears
Grizzly bears are omnivorous although their digestive system is that of a carnivore. They consume a wide range of food items constituting both plants and animals. They prey on mammals such as bison, bighorn sheep, mule deer, white-tailed deer, caribou, elk, and sometimes black bears. They always choose calves or injured animals as opposed to a healthy adult. Grizzlies also feed on fish such as bass, trout, and salmon. It has also been observed that grizzly bears which have access to protein-rich diet, particularly in the coastal regions are typically larger compared to individual grizzlies found inland. They also scavenge for food and often consume carcasses left by other animals.

FAQ
What kind of fish do grizzly bears eat?
Grizzly bears eat a variety of fish, with salmon being a particularly important food source. They gather near rivers and streams to feed on spawning salmon, consuming large quantities when available.
Do bears actually eat salmon?
Salmon are a high calorie meal for a bear. A sockeye salmon contains about 4500 calories, but the fattiest parts of the fish contain the most calories proportionally. Bears know this and prefer to eat the skin, brain, and eggs—the fattiest parts of a salmon—when fish are in abundance.
Do grizzlies only eat the skin of salmon?
Occasionally, a bear eats the salmon meat, not just the skin and roe. Shown below, Lerch, the older bear missing a right ear, ate the bones, meat, and skin starting from the tail .
