Alaskan Pollock fish is the Gadus chalcogrammus fish.
The Alaska pollock or walleye pollock is a marine fish species of the cod genus Gadus and family Gadidae.
It is a semi-pelagic schooling fish widely distributed in the North Pacific, with largest concentrations found in the eastern Bering Sea.
Pollock swim in HUGE schools - think the size of a house - and they pack into those schools very tightly.
That means you can catch enormous quantities, and the catch is pretty “clean” - meaning it's almost entirely pollock (not other fish) in your net.
Those factors make them efficient to catch.
As far as the nutritional value of pollock, like salmon, tuna and cod, it is a good source of lean protein and low in saturated fat.
All of these fish are also a good source of vitamin B12, phosphorous, and selenium.
Salmon is the highest in omega 3 fat, which is one of the best reasons for eating fish.
Alaskan Pollock have a mild, delicate taste with white flesh, large flakes, a slightly coarse texture and a low oil content.
They have a similar but somewhat milder flavor as haddock or cod.
Cod is better than Alaska Pollock due to its higher percentage of protein, minerals and lower cholesterol.
Cod contains a higher number of thiamin, iron, niacin, folate, potassium, phosphorus, calcium and zinc.
Cod is slightly sweeter and its flesh holds together better when cooked than Alaska Pollock.
According to average measurements of commercial seafood measured by the FDA, Pollock came in at an average of 0.031 PPM (parts per million) of mercury (source: FDA).
This is considered a low mercury level.
