Pollock fish

Introduction to Pollock

Pollock or Pollack (Pollaccius virens) belongs to the cod family and is a marine fish found in temperate, subarctic waters around the world. It is often mistaken for or used as a substitute for other fish living in the Atlantic, Pacific and Arctic Oceans, such as cod.

Pollack is an economically significant commercial and recreational fish responsibly managed by the International Council for the Exploration of the Sea (ICES) to ensure future populations.

This fish is an essential component of many traditional dishes, such as fish chowder, and is commonly smoked and dried for use in salads and soups.

Physical Characteristics

Pollock is recognisable by its light brown to silver sheen hue with side-to-side lateral line and numerous shallow black spots along its sides. The species has a sloping back, an extended tail, large eyes, and fleshy lips. Its digestive organs give the fish a distinct ‘peanut-shaped’ profile in the water.

When fully grown, pollock can range from 8 to 24 inches (20 to 62 cm) in length and weigh one to seven pounds (0.4 to 3.2 kg).

Habitat and Feeding

Pollock generally inhabits water depths of 30-350m and temperatures of 6-10C. Geographically, it lies in the region of the Pacific Ocean, heavily influenced by oceanographic currents.

Pollock primarily feeds on small fish and marine invertebrates, such as crustaceans. The type of prey they consume can vary seasonally, so they must move around to remain in areas where their food source is abundant.

Fisheries and Uses Fishing for pollock has a long history and occurs in fresh and saltwater environments. These fisheries fall into recreational and commercial. Most North Pacific pollock fisheries are certified sustainable by the Marine Stewardship Council (MSC). The fish is available all year round, especially in winter, when stocks are higher.

Population and Conservation

The US Regional Fishery Management Councils are responsible for the sustainable management of pollock throughout its range. To demonstrate responsible leadership, the Marine Stewardship Council has certified the pollock fishery in Alaska, the northeast Arctic, and the Ross Sea fishery.

In 2010, the International Fisheries Commission approved fishing limits in the Atlantic pollock fishery. Fisheries have focused on improving the sustainability of the species and ensuring sustainable management. Methods of capture include trawling, gillnetting and purse seining, although currently, some areas prohibit trawling. Gear and fishing techniques improved, reducing the bycatch of other species. Discards of pollock are very low, typically less than 1% of the total catch.

Stock assessments take place each year to ensure that the health and population size of pollocks remain healthy. Maximum sustainable yield (MSY) is a critical component of management, ensuring that enough pollock are left each year to reproduce and maintain successful reproduction of the species in the long run.

Regulations have also been implemented to promote pollock fisheries’ sustainability, including catch limitations, gear restrictions, closed seasons, size limits, and bycatch limits. The use of sorting grids and turtle excluders has successfully reduced bycatch.

Conservation Status

Various conservation efforts are in place to better preserve the pollock population. These include the International Commission for the Conservation of Atlantic Tunas (ICCAT) and the World Wildlife Fund (WWF), limiting the number of fish caught in a fishery and advocating for sustainable fishing methods.

The Sustainable Fisheries Partnership and the Marine Stewardship Council identify Pollock as a sustainably-managed species. The latter’s certification program provides evidence that the Pollock fisheries are managed responsibly with minimal environmental impact.

Other conservation efforts dedicated to the pollock population include:

• Research into their life history and biology.
• Identifying potential problems within the fishery.
• Advocating for strict fishery management practices.

Additionally, the formation of Marine Protected Areas (MPAs) and selective fishing gear aim to reduce fishing pressure on the species and allow it to recover.

Pollock’s Diet

Pollock feeds mainly on fish, crustaceans, molluscs, and plankton. They adapt their diets to their developmental stage, migrate to areas with plentiful food sources, and adjust depths to find optimal temperatures for foraging. As they reach adulthood, they become more of an ambush predator, preying on smaller, slower fish.

Reproduction

Life Cycle of Pollock

The main stages of a pollock’s life cycle are egg, larvae, juvenile and adult. Spawning usually occurs between April and September, with peak spawning in the Northern Hemisphere occurring in May to June and July to October in the Southern Hemisphere.

Pollock spawns typically in shallow coastal waters. The eggs have adhesive properties and will stick to the substrate lying on them, making protection from predators difficult. The pollock larvae are planktonic and remain in the open ocean until they are large enough to settle on the bottom. An adult pollock can lay up to one million eggs per spawning season, which hatch in two to three weeks.

Temperature and seasonality are significant factors that affect the pollock’s life cycle. As the season changes, so does its movement; they will move to deeper waters or areas of low temperatures. Young pollock are tiny individuals, around 4 cm (1.5 in) long, and grow steadily over 5-6 years until they reach sexual maturity.

Classification

Pollock (scientific name: Pollachius) is a group of fish in the Gadiformes family. Several names exist in different languages, such as colin (French), Gadus virens (Latin), peling (Norwegian), lascia (Italian), Morue touladi (French) and Schellfisch (German). In some parts of Canada, it is called either Hammers or Bulldogs.

Etymology

The term pollock derives from the Scottish Gaelic poll, which means cobbled fish. It is an old term for a particular hook used to catch pollock. The scientific genus name for Pollock is Pollachius, derived from the Greek word pollux, which means sailor or navigator; said to be an appropriate name for the fish due to its navigable swimming pattern.

Significance

Pollock is a commercially significant fish, harvested for its meat and omega-3 oils, widely used in the food and pharmaceutical industries. Recreational fisheries offer excellent opportunities for pollock, with many fishing methods employed to target them. Pollock has been an instrumental part of the history of fishing communities in the northern Atlantic for centuries and continues to play a significant role in local economies.

Uses

Due to its mild-tasting, flaky flesh, pollock appears in various dishes, including seafood chowder, fish tacos, stews, and fish and chips. It is also a popular choice for batters, smoked fish and sandwiches. Pollock can be cooked in many ways, including pan-frying, baking, grilling, broiling, and frying. Its flesh and oil are also refined and used in cosmetics, food additives and pet food products.

Popularity and Availability

Pollock is one of the most consumed seafood items in the United States and is widely available in fresh, frozen and canned forms.
