Pollock or pollack [1] (pronounced / ˈ p ɒ l ə k /) is the common name used for either of the two species of North Atlantic marine fish in the genus Pollachius. Pollachius pollachius is referred to as "pollock" in North America, Ireland and the United Kingdom, while Pollachius virens is usually known as saithe or coley in Great Britain and Ireland (derived from the older name coalfish).

In Loch Lomond, this fish exhibits a pattern of daily migration to feeding sites and of seasonal migration to breeding grounds. Before the breeding season, the mature males begin to congregate in deep water near the spawning beds; these are shallow areas of gravel and pebbles washed by waves.

Human-induced factors including increased greenhouse gas emissions - increases in atmospheric CO 2 and other long-lived greenhouse gases like methane, nitrous oxide and halocarbons - and changes to land cover - which refers to the replacement of darker forests with paler croplands and grasslands - have led to this rapid increase in temperature, which has taken place over the past 50 years.
Resident fish of this area include reef fish like rabbitfish and parrotfish, pelagic fishes such as sardines, anchovies, mackerel, and sailfish, and higher trophic predators such as sharks. [29] Fisheries have a strong presence in this area and depend strongly on the changing oceanic conditions, largely dependent on the Kuroshio Current.
The Southern Ocean has supported fish habitats for 400 million years; however, modern notothenioids likely appeared sometime after the Eocene epoch. [3] This period marked the cooling of the Southern Ocean, resulting in the stable, frigid conditions that have persisted to the present day. [3]
The sand goby (Pomatoschistus minutus), also known as a polewig [2] or pollybait, [2] is a species of ray-finned fish native to marine and brackish European waters from the Baltic Sea through the Mediterranean Sea and into the Black Sea where it occurs in sandy or muddy areas of inshore waters at depths of from 4 to 200 metres (13 to 656 ft).
