Introduction
These species, Pollock fish, Pollachius pollachius, and Pollachius virens, are known for their elongated bodies, deep green coloration, and pale lateral lines. They are carnivorous, lively, and usually found in schools, growing up to 1.1 meters long and weighing up to 16 kilograms.
Habitat
Pollock fish are quite the travelers! They are found on both sides of the North Atlantic Ocean. In the western Atlantic, their favorite hangout spots are between Cape Cod and the Strait of Canso. At the same time, in the eastern Atlantic, they love to chill around Iceland, the North Sea, and off the northern coast of Norway.
When they’re just little fish, they prefer to stay in the shallow coastal zone for the first two years of their life. This is like their nursery, where they can hide and play among the rocks and macroalgae. But as they grow up, they crave adventure and move out into deeper waters, swimming in large schools throughout the water column.

Respiration
Like other fish, Pollock breathes through their gills. This is how they extract oxygen from the water to survive. They take water through their mouths, then push it out through their gills. As the water passes over the gill tissues, oxygen is absorbed into the bloodstream, and carbon dioxide, a waste product, is expelled into the water.
Fertilisation
The female Pollock releases her eggs into the water, and the male fertilizes them outside the body. This process is known as external fertilization. The number of eggs a female produces can vary. Still, some females can make several million eggs in a single season! It takes about a week or two for the eggs to hatch and the larval young to emerge.
Once the little ones are hatched, they start their life in the shallow waters, just like their parents did, and the cycle continues. Some Pollock begin to reproduce by age 3 or 4 and are highly fertile.

Why Pollock fish is Cheap?
Pollock fish, known as coalfish, Alaskan Pollock, Boston bluefish, saith, or harbor pollock, is among the most affordable seafood options available. This is primarily due to its abundance and the efficient methods used to catch it. Pollock is a semipelagic schooling fish. It tends to gather in large groups, making it easier for fishermen to acquire in bulk.
Moreover, Pollock is a fast-growing species with a relatively short lifespan of about 12 years. Some Pollock begins to reproduce by age 3 or 4 and are highly fertile, so each generation replaces aging or harvested fish in just a few years. This rapid reproduction and growth rate contribute to its plentiful supply and affordability.
