Pollock fish belongs to the cod family, swimming in schools. A clear white stripe is visible on its sides, running parallel to its back, which is the main difference from other waterfowl brethren. There is also one small nuance by which you can determine the type of fish - this is a small protrusion forward.
Period of active migration
The period of active migration of this species begins in the spring, when the fish head north in a friendly school. And in the fall, they choose southern water spaces. In summer they can be seen not far from the Murmansk coast. When young, pollock fish eats exclusively like an aristocrat; its menu includes caviar and crayfish. But as he gets older, he announces a hunt for small fish. Its life span is 30 years.
Pleasant taste
Pollock fish has a characteristic flavor that is very popular in the culinary world among cooking experts. They have a saying: “If you haven’t tried pollock at least once, you don’t know the taste of real fish.” It is characterized by a unique, and at the same time more pronounced marine flavor, which distinguishes it from other species.
Habitats
Its habitat is: part of the Atlantic and sometimes pollock swims in coastal areas, and when it enters the open sea, it prefers a depth reaching 250 meters.
Beneficial features
Pollock fish, the beneficial properties of which are very familiar to gourmets, is valued for its unusually tasty and tender meat, very nutritious and even healing. Being a real storehouse of proteins and vitamins B12, sodium, potassium and selenium, this product is used as a preventative against liver diseases. Doctors also recommend adding this type of fish to the diet to treat the musculoskeletal system and thyroid gland due to its high content of phosphorus and iodine.
Fried pollock with potatoes
The owner of grayish meat with a spicy delicate taste is pollock fish. Recipes for preparing her fillet are in great demand both in restaurants and at home. Housewives who managed to buy this truly delicious sea creature scrupulously approach the preparation of the fish dish, anticipating its elusive aroma, as well as the exquisite combination of juiciness and fragility of the future delicacy.
Peel 6 potatoes, rinse and cut them into thin slices. Peel two onions and hold under cold water to prevent your eyes from watering. Cut them up. Heat a frying pan, pour in vegetable oil and place the prepared ingredients there. After lightly frying, pour in a glass of vegetable broth, a glass of cream, season with spices, and simmer the entire contents for about 30 minutes, remembering to stir occasionally.
Rinse under running water and dry with a napkin, then rub with salt and ground pepper. After 15 minutes, roll the fish in flour. Fry the fish flesh in a frying pan on both sides until golden brown, turning it occasionally.
Place the stewed potatoes on a plate, place a piece of pollock on the side and garnish with a sprig of dill on top. Bon appetit!
Modern stores and large shopping centers offer a huge selection of river and sea fish. In particular, you can often see pollock on the shelves. It is not as popular as other varieties of fish. And completely in vain. If you know some cooking secrets, “seafood” will turn out very tasty.
The benefits of sea fish
Therefore, if we examine this issue from a sanitary and hygienic point of view, sea fish is much safer than river fish. Eating this fish and its other, more famous “relatives” is an excellent way to enrich your daily diet with protein and other beneficial substances.
Habitat and appearance
The pollock lives in the North Sea. In particular, this fish is actively fished in Norway and the north of Great Britain. On the territory of the Russian Federation, this species lives in the Arctic Ocean, so it is also caught in Murmansk and other cities in the Arctic. Pollock has an elongated, slightly elongated body and shiny silver scales. It is a close “relative” of such valuable commercial marine fish as:
In its natural habitat, pollock feeds on plankton, water beetles, small crustaceans and shrimp and other living creatures inhabiting the North Sea. She also does not disdain small fish, which swim in schools in the water, swallowing them whole. This is a real predator, a thunderstorm of the seas. Reproduction occurs with the help of eggs. Fishing is carried out on professional fishing vessels.
In everyday life, many ignorant people mistakenly confuse pollock with saury. However, these are two completely different fish that have nothing in common with each other. Most likely, this confusion is due to the fact that saury appears on the shelves of domestic stores, markets and supermarkets much more often than its almost complete namesake.
Pollock is a fairly large fish, on average, the length of an adult is from seventy to ninety centimeters. The world's largest specimen, caught off the coast of Norway, was 120 cm long. Males are slightly larger than females. When the fish goes to spawn, the eggs scatter very far. The fish is distinguished by its fertility, so its fishing has recently become widespread. This is a real long-liver of the North Sea: it is known that individual individuals, under favorable conditions, lived for more than thirty years, and this is a real record for inhabitants of the deep sea.
Just a few years ago, the species was not popular because fatty fish, such as salmon, were in fashion. However, in recent years, due to the active promotion of a healthy lifestyle and proper nutrition, “skinny” varieties have also taken their rightful place on the shelves. If you prepare pollock dishes correctly, no one will notice the lack of fat.
Useful properties of pollock
Pollfish has a high nutritional value and, when properly prepared, has a delicate flavor. The variety, despite the low amount of fat, contains a high concentration of useful substances such as:
- Proteins;
- Essential fatty amino acids;
- Folic acid;
- Vitamins D, E, A.
Also, pollock, like its other marine “relatives,” is very rich in phosphorus. Phosphorus improves brain activity, has a beneficial effect on memory and the state of the nervous system, and also helps strengthen bones, teeth, and nails. It is useful to eat this fish not only fresh, but also in canned form: canned food contains small bones that are easily digested, perfectly absorbed by the body and rich in calcium.
Folic acid makes this fish an indispensable product in the diet of pregnant women and couples who are just planning to conceive a child. Experts say that regular consumption of low-fat sea fish during pregnancy reduces the likelihood of serious developmental defects in the fetus, and also significantly improves the woman’s overall well-being.
In order to get the maximum benefit from the product, it is recommended to purchase chilled or frozen pollock. Whole fish is preferable to fillets, since fillets come in different quality, sometimes during freezing they become covered with a thick layer of ice and lose many of their beneficial properties. You should not buy cutlets and so-called “sticks”, because you cannot be one hundred percent sure of the quality of such semi-finished products.
It is quite possible that they contain only 10-20% pollack, and the rest is pollock or hake. Unscrupulous manufacturers often take advantage of the fact that all sea fish have approximately the same taste and conduct unauthorized “experiments” on customers, varying the composition of semi-finished products at will. However, the label on the packaging does not always correspond to the actual composition of the product.
Pollock is rich in valuable proteins and is practically equal in nutritional value to lean beef. This is an indispensable product for those who, for health reasons, do not eat meat or observe religious fasts. It should also be noted that the proteins contained in this variety are absorbed by the body more easily than beef or pork protein.
Dishes from pollock (as well as from hake, track, pollock) should be included in the mandatory diet of those who suffer from various diseases of the gastrointestinal tract: gastritis, pancreatitis, gastric and duodenal ulcers. Children can eat this fish starting from eight months, in the form of puree or cutlets, as well as in soup. But you need to remember that any fish products can be strong allergens or cause individual intolerance.
Secrets of cooking
Many housewives believe that pollock has a rather bland taste and is a little dry. For this reason, it is not in such demand in stores and supermarkets as pink salmon or salmon. Indeed, if you simply fry it in oil, like any river fish, it will be very dry and practically inedible. The best way to prepare this variety is to simmer over low heat in a deep bowl, adding a sauce made from flour and white wine. During the stewing process, sautéed onions and roots (carrots, parsley, finely chopped celery root) are also added. Here are some more ways to cook sea fish:
Canned pollock
Sometimes canned pollock ends up on supermarket shelves. The best of them are considered to be those prepared directly on the ship, immediately after catching the fish. As a rule, they are made in Murmansk or Norway. Here are the main types of such canned food:
The caviar of this fish has a delicate, slightly salty taste; it goes well with sandwiches made from black bread with butter. Pollock liver is rich in vitamin D and is almost as concentrated as cod liver. It can be added to salads or spread on sandwiches instead of butter. Fans of home canning can also independently preserve pollock fillets using an autoclave; the shelf life of such products is no more than two years (subject to all storage conditions).
This variety is practically never found in dried or dried form. When choosing canned food, you should carefully study their composition. The ideal option is a jar that says: “saithe, water, black pepper (or other spices)”, without preservatives or other food additives.
Fish selection criteria
When choosing pollock in a supermarket or market, you should first of all pay attention to its smell. It should be fresh, sea-based. A musty smell indicates that the product is no longer fresh, and you should refrain from purchasing it.
When purchasing frozen fillets, it is not recommended to purchase products in opaque packaging. If there are no other options, the packaging needs to be shaken thoroughly. A characteristic noise when shaking indicates that there is a large amount of ice inside. This happens when fish is repeatedly frozen and thawed, as well as in cases where the manufacturer deliberately wants to increase the weight of the product due to ice.
If the fish is slippery, sticky, or unpleasant to the touch, this also indicates poor quality and possible staleness of the product. The scales of high-quality pollock should be shiny, not dull.
“Seafood” is an indispensable product in the diet of a modern person. In order for sea fish to be tasty, you need to prepare it correctly and choose quality products. Pollock is one of its most valuable varieties. It’s a shame that so far not all gourmets have been able to appreciate it. It should occupy an important place in the diet of those who care about their health, along with cod, hake and other inhabitants of the northern seas. It is very easy to prepare pollock, the main thing is to make it soft and aromatic, spices and a variety of sauces (both store-bought and home-made) will help with this.
Pollock is a prominent representative of the cod family. This is a marine creature that gathers in schools to migrate over long distances. Such movements are associated with the search for favorable conditions for spawning.
The appearance of the fish has characteristic features: the body is oblong, 3 fins are located on top of the back, 2 more are located near the anus. On the sides of the body, the lateral line in the form of a light stripe is clearly defined. In adults, the lower jaw is slightly pushed forward.
The upper part of the body is dark in color, and closer to the belly it turns into a silvery-white color. A distinctive feature of all codfish is a short, barely noticeable chin barbel. The size of pollock can reach over one meter, while its weight will be 18 – 20 kg.
The spawning period begins in January and lasts until June; the fish chooses places for spawning at a depth of up to 200 m. The most favorable places for pollock breeding are the southern regions. The optimal water temperature for spawning should not exceed 10 degrees. The bottom surface should have fairly soft soil.
On average, a mature individual is capable of bearing about 4 million eggs, but there are specimens that produce 5–8 million eggs. Pollock caviar belongs to the pelagic type, where small (1 mm in diameter) eggs float on the surface of the water and have a bright color. Eggs are low in protein.
2 weeks after spawning, the larvae hatch, their length is already 3.5 mm. Thanks to the sea current, the hatching larvae are carried over long distances of hundreds of kilometers, which explains their wide distribution. Thus, representatives of the cod family can be found near the Russian coasts.
The main food for the fry is the eggs of other fish species and small crustaceans. When the younger generation grows up a little, various small fish will appear in their diet.
When is the best time to catch pollock?
Pollock is especially attractive to fishermen because it can be hunted all year round. In winter, fishing from the shore is ineffective, given that the fish sink to depth, but their activity does not decrease at all. During the colder months it is advisable to fish from a boat.
The fishing season from the shore begins in March, the coveted trophy goes hunting for coastal invertebrates and fish. The highest activity of the predator is observed in August – September, and closer to November the bites noticeably worsen.
Pollock is quite dependent on the ebb and flow of the tides. To fish for such a predator, it is recommended to acquire a special tide table for the current year in a particular region; it can either be downloaded from an Internet resource or purchased at a fishing store.
According to the information about the time of the tide, you need to plan your hunting trip; it is advisable that fishing begins before 2 hours before the specified time. It is this time period that is the best time for catching pollock. After the tide has passed and it is time for the tide to go out, the intensity of the bite gradually decreases.
You can count on a qualitative and quantitative catch at early dawn and at night.
In summer, the predator is caught in the White, Okhotsk, and Baltic and Barents Seas. This is due to the return of the main schools of large individuals after spawning. It is recommended to choose promising places for fishing near the coastal zone, at the transitions of the rocky bottom to the sandy bottom.
The winter hunting season begins with the establishment of real ice and lasts until mid-winter. After which the fish go to spawn, only the fry remain.
What gear is needed on the side?
Large pollock is a fairly strong fish that offers powerful and persistent resistance when fished.
The key to a successful predator hunt is properly prepared gear:
- The rod must be of high quality, with a good safety margin and test load up to 300 g, tool length 240 cm.
- Multiplier reel model with a capacity of 400 m of cord. To simplify the fishing process, it is advisable to purchase a reel with a large gear ratio (6 – 7).
- Braided fishing line with a breaking load of 40 kg is perfect for such purposes.
If fishing involves the use of a streamer, you must choose a class 14 fly rod.
Among the traditional gear for sea predators, there is a bottom fishing rod, a vertical trolling method, and a spinning rod.
The usual version of the sea donkey is used as a bottom fishing rod. For equipment, high-quality fishing thread and stainless steel hooks are suitable.
The high efficiency of vertical trolling has been proven by practice. For equipment, fishing thread with a cross-section of up to 0.4 mm is used. A spoon of either white or bright color is used as a catching bait. The optimal hook size is 25 – 30.
It is especially good to hunt for lures during high tide; the bait is actively moved in the horizontal direction with an amplitude of 1 m.
Sea spinning is used to fish from a floating craft at a depth of 100 - 200 m. This way you can fish a large area where pollock lives, in particular bottom elevations. Here the fisherman will need certain knowledge and experience.
An article by reading which you will learn everything about fish.
How to catch more fish?
I have been active fishing for quite some time and have found many ways to improve the bite. And here are the most effective:
- . Attracts fish in cold and warm water with the help of pheromones included in the composition and stimulates its appetite. It’s a pity that Rosprirodnadzor wants to impose a ban on its sale.
- More sensitive gear. Reviews and instructions for other types of gear can be found on the pages of my website.
- Lures using pheromones.
Fishing Features
Although pollock sticks to the bottom, it can take bait not only from the depths, but also on the surface. It is recommended to do the hooking confidently and quickly. To prevent the predator from getting off the hook, you must use high quality and durable gear.
When fishing, the predator tries to free itself from the hook by making circular movements, and such actions contribute to the breakage of the tackle. There is a high probability of spoiling the tackle in winter when the fishing thread rubs against the ice.
Pollock fish - reviews from fishermen
On the vastness of the Internet resources, in particular on fishing forums, you can find a sufficient amount of information about catching pollack, about its behavioral characteristics, and about catchable baits.
Based on numerous reviews from fans, we can conclude that pollock is truly an interesting and desirable trophy for every fisherman. As an object of fishing, the fish attracts with its disposition, caution and powerful resistance when playing.
The main thing, as experienced spinning anglers say, is to take it with you when hunting exceptionally durable tackle, otherwise you may be left not only without a catch, but also without your favorite fishing rod.
Now only mine bites!
I caught this pike using a bite activator. No more fishing without a catch and no more looking for excuses for your bad luck! It's time to change everything!!! The best bite activator of 2018! Made in Italy...
How long has it been since you had a really BIG CATCH?
When was the last time you caught dozens of HUGE pike/carp/bream?
We always want to get results from fishing - to catch not three perch, but ten kilogram pikes - what a catch! Each of us dreams of this, but not everyone can do it.
A good catch can be achieved (and we know this) thanks to good bait.
It can be prepared at home or bought in fishing stores. But stores are expensive, and to prepare bait at home, you need to spend a lot of time, and, to be fair, homemade bait does not always work well.
You know that disappointment when you buy bait or prepare it at home and only catch three or four bass?
So maybe it’s time to use a truly working product, the effectiveness of which has been proven both scientifically and in practice on the rivers and ponds of Russia?
It gives the same result that we cannot achieve on our own, especially since it is cheap, which distinguishes it from other means and there is no need to spend time on production - you order it, it’s delivered and you’re good to go!
Of course, it is better to try once than to hear a thousand times. Moreover, now is the season! This is a great bonus when ordering!

Long and strong migrations are characteristic of pollock. They move in their flocks from north to south, depending on the time of year. In frequent cases, the fish is found near the Murmansk coast.
The waters of the North Sea, Atlantic and Baltic are favorite places for fish of this species. Like all other cod fish, pollock lives at a depth of about 245 m. It prefers a bathymetric water thickness of 36 to 110 m. There are cases that it is located at the very bottom.

The end of March, the beginning of April is the right time for females to migrate to spawn. After deposition, the eggs drift freely along with the sea current. On average, after 14 days, small larvae emerge from it, 3 mm in size. Since they move freely with the current, they can be observed far from their spawning sites.
As already mentioned, growing fry eat fish eggs, plankton and crustaceans. Their location is the coastal zone of the seas.
