Alaska pollock are deep-oceanic, bottom-dwelling, non-migratory fish living at a depth range of 30-500 m. Its body is streamlined, olive-green to brown on the back. Its sides are silvery with yellow to brown speckles. The ventral surface is pale and smooth. Its dorsal fins are widely separated. The silvery lateral line is quite straight and continuous to about the back end of the first dorsal-fin base.

Alaska pollock is distinguished from other members of the cod family, such as the Atlantic cod by its:

  1. lower jaw projects beyond the upper jaw,

  2. the tail is forked, and

  3. the straight lateral line.


Alaska pollock are found throughout the North Pacific Ocean but are most common in the Bering Sea. It is a fast-growing fish that typically reaches 1 to 3 feet long at maturity and weighs between 2 and 5 pounds. They spawn between late February and early May.

Its life span is about 12 years, but a typical catch is anywhere between 5 and 7 years.


Alaska pollock is a benthic (demersal) fish that prefers to live close to an ocean bed in areas of rocky substrates. They do not make long-distance mass migrations.

Their diet changes at different life stages: juveniles feed on invertebrate eggs and small planktonic crustaceans, while adults feed mainly on copepods, krill, and other fishes, mainly juvenile pollock.

Pollock predates on a variety of bottom-dwelling creatures. Juveniles feed on invertebrate eggs and small planktonic crustaceans, while adults feed mainly on crustaceans, sea stars, and small fish like herring and juvenile pollock.

Health benefits of Alaska pollock

  1. Alaska pollock is a moderate source of essential fatty acids, protein, minerals, and fat-soluble vitamins like vitamin A, E, and D.

  2. It is non-oily, deep water fish, and therefore, low in calories and saturated fats; 100 g holds just 92 calories in comparison to 91 calories in halibut and 82 calories in cod.

  3. It composes lean, flaky white meat that composes a good amino-acids profile. 100g fish provides 19.4 g/100 g (34% of RDI). Protein composition is complete in the sense that all essential amino acids are in a healthy proportion.

  4. Science-backed studies suggest that eating seafood can help decrease the risk of heart attack, stroke, obesity, and hypertension. Seafood is low in saturated fat and higher in “heart-healthy” polyunsaturated fat, including omega-3 fatty acids.

  5. Being a deep-water fish, cod contains little vitamin A in its flesh. Nonetheless, its liver carries ample amounts of omega-3s such as ALA, DHA, and DPA to help keep hair, mucosa, and skin healthy.

  6. Research studies suggest that omega 3's, particularly DHA, play an important role in the development of the nervous system, especially in infants and children.

  7. According to Cornell University and the New York Sea Grant Extension Program. 2012- The fatty acids play a crucial role in decreasing blood pressure and heart rate and help improve cardiovascular function. For example, research has shown that omega-3 fatty acids decrease the risk of arrhythmias (abnormal heartbeats) that can lead to sudden death.

  8. In adults, several large trials have evaluated the effect of fish or fish oils on heart disease. In the "GISSI Prevention Trial, heart attack survivors who took a 1-gram capsule of omega-3 fats every day for three years were less likely to have a repeat heart attack, stroke, or die of sudden death than those who took a placebo".

  9. Alaska pollock fillet composes B-complex vitamins such as niacin, and pyridoxine (B-6). It is also a good source of vitamin E, vitamin B12 , thiamin, and riboflavin.

  10. Its flesh contains just 0.031 ppm of mercury in its flesh. US FDA categorizes Alaska pollock in the "best choice" section considering mercury levels in its flesh. The recommended consumption is 2-3 servings (8-12 ounces) per week for Alaska (walleye) pollock.

  11. Further, it is a natural source of rich minerals including iodine, calcium, zinc, potassium, phosphorus, and magnesium. Iodine is an important trace element in human nutrition and is essential for thyroid hormone synthesis.

  12. Alaska pollock roe is a rich source of protein and minerals than its white meat. Its roe is also an excellent source of vitamins A, E, and D.
