If you are looking for fish stars of cold northern seas, dark and winter, then Cod and Pollock are those fish. These two are the ones that don't often steal the limelight, but they are a real fishing lottery win for those who know what they are looking for. 

They belong to the Gadidae fish family, known for their elongated bodies, three dorsal fins, and one mustache on the lower jaw, but that doesn't mean they play life games by the same rules! The Cod is heavy, robust, and calm, while the Pollock is a more dynamic player, fast and ready to surprise at any moment.

Cod is the king of the depths, moving gracefully and calmly, while Pollock hides in the shadows of wrecks and rocks, waiting for the right moment to jump out and make a show. If you are an angler who is not bothered by the cold but rather inspired by it, let's dive deeper and discover what makes these fish such special catches!

Key Difference: Cod vs. Pollock

It is easy to confuse these two fish in the cold and turbulent waters of the northern seas. At first glance, they act similarly and hunt in similar habitats, but as is usually the case, they have significant differences. Cod plays the card of strength and stability, while Pollock plays the card of speed and advantage, but there are more than just those nuances. 

Size and Weight

Cod and Pollock are like playing on completely different fields in size and weight! Cod leads the way by weight; it dominates actual northern waters and can grow to an impressive 5 feet long and weigh over 88 pounds. As such, it presents durability and is a great challenge for anglers.

Pollock is smaller, but its weight is not to be underestimated. It reaches a length of 1.5 to 3 feet, a weight between 4 and 13 pounds, and the largest specimens can reach 33 pounds. However, the secret of his strength lies in his speed and explosive energy.

The differences in size and weight also shape their fighting styles. Cod enters the fight slowly and with authority, standing among the true giants of the sea, while Pollock counters with sudden moves and dynamic resistance, making for a fast, unpredictable adventure.

Coloration and Markings

Cod and Pollock are similar in color but differ in shades and intensity. Cod has a brownish-green or olive-grey back that blends with the seabed, adorned with mottled darker markings that make it nearly invisible among algae and rocks. Its lower body is lighter, almost white, helping it hide from predators below. The most distinctive feature is its long, prominent lateral line running the entire body length.

Pollock has a dark, almost blackish back that gradually turns into a golden-green shade along the sides. This camouflage gradient of colors, often interspersed with grey-silver tones, gives it a striking shine and makes it much easier to spot than Cod. Also, it has a lateral line, but it is less prominent. An unambiguous distinguishing feature is a dark, almost bronze spot behind the gills as a personal mark.

Lifespan

Cod is a real longevity champion of northern and icy waters. It is known for its long lifespan, which can reach 25 years in ideal conditions. Some specimens even live longer. That's plenty of time to grow to massive proportions and develop "legend" status. Cod go through different stages of development, and older specimens often represent the most significant challenge and trophy.

Pollock lives shorter, typically between 10 and 12 years, but makes up for it with an active, fast-paced lifestyle. Constantly moving and maturing quickly, it becomes a fierce predator in a short time. This dynamic nature translates to a fast, intense fight for anglers, while Cod, with years behind it, offers a slower but equally demanding challenge.

Habitat and Behaviour

The habitat and behavior of Cod and Pollock are entirely different, though they are seemingly similar fish. Cod prefers deeper, cooler water close by and moves slowly. On the other hand, Pollock is much more active and is often found in middle waters, where it swims quickly through water currents, following schools of smaller fish. Find out more details below.

Where to Find Cod and Pollock

Cold waters are the common characteristic of the habitat of Cod and Pollock. Both of these marine predators rule the cold waters of the North Atlantic. Cod lives in deeper, colder waters near the bottom of the sea, from the northeast coast of the United States across Canada to the cold seas around Iceland, Norway, and the British Isles. It likes rocky and sandy terrain and often stays in the place where it feeds on crabs, squid, and smaller fish.

Pollock prefers shallower waters and is often found closer to shore. It inhabits northern seas, especially along the Atlantic coast of Europe, from Norway to northern Spain, and in the Western Atlantic. More active in mid-water, it patrols coastlines, underwater reefs, fjords, and sea cliffs. Though their habitats differ, both fish thrive in cold, rugged environments, offering exciting challenges for adventurous anglers.

Seasonal Behavior

Cod and Pollock's behavior is intricately linked and changes according to seasonal changes, water temperature, and food availability. Although they are available throughout the year, their migration patterns and feeding habits vary. To better understand them, we provide an overview of their behavior throughout the seasons.

Spring

Spring is when both fish increase their activity; they move from their winter places to shallower waters. Cod heads for the seas around the rocky bottom and edges, looking for their favorite prey, crabs and smaller fish. Pollock, meanwhile, follows warmer currents, moving closer to the surface in search of abundant baitfish. Both species are aggressive and careless in the spring, making them relatively easier to catch.

Summer

Summer is the time when Pollock shines. It is very active, especially early in the morning and late at night, when the temperatures are more favorable. Cod live mostly in the middle layers of water, often near structures like underwater reefs. They stick to colder depths, often in the thermocline, where they can wait for prey invading their territory from an ambush.

Fall

With the arrival of fall, the water temperature drops, and the Cod begin their migration towards deeper waters. There, they gather in larger schools and begin a period of aggressive feeding to prepare for the winter months. Pollock can still be found in the shallows, feeding on the last remnants of baitfish. This transition period is an excellent time for anglers, as both species remain opportunistic feeders and can be caught on various bait and techniques.

Winter

As winter sets in, Cod retreats to reasonably deep water, looking for slower currents and areas with enough cover. Over time, they become less active, relying on stored energy to sustain them through the colder months. Depending on the weather, Pollock wanders a bit more and goes into deeper water, but it can still be caught if strategically targeted.

Both fish feed less frequently, making winter fishing more challenging and requiring anglers to adopt slower, more deliberate techniques.

Best Time to Catch Cod and Pollock

Given that they live in mostly colder areas, the best time to catch them is when they are more active, spring and summer, and the beginning of fall if it is warmer. Theoretically, both fish are catchable throughout the year, but you will need more patience and powerful gear during late fall and winter.

The Cod then retreats to the depths and shows significantly less activity, while the Pollock can still be caught, if only with a well-designed strategy. If you want productive fishing, stick to late summer and early fall when temperatures increase.

Feeding Habits

Both fish are primarily opportunistic, but they take a different approach. With their robust bodies and formidable jaws, Cod are masters of ambush, relying on stealth and patience, while Pollock are the acrobats of the ocean. They actively hunt schools of smaller fish and use speed and impulsiveness to hunt down their meals.

Cod's Favorite Food

Cod likes to eat, and since it lives in cold waters, its hunger is very opportunistic. It mostly doesn't choose, and its menu includes smaller fish, crustaceans, and cephalopods. The basis of food is herring, mackerel, and sand eels. Crabs and shrimp are also important because they provide essential nutrients, while squid and other cephalopods become prominent in areas where they are abundant.

Its feeding habits change with the seasons. Cod eats most actively during spring and summer, taking advantage of plentiful food sources. In winter, its metabolism slows, and it relies more on stored energy, reducing its feeding activity.

Pollock's Favorite Food

Pollock is an active predator, feeding on smaller fish and invertebrates, playing a vital role in the marine ecosystem. Its diet includes herring, sand eels, capelin, and various crustaceans like shrimp and krill, which provide essential nutrients. Like Cod, Pollock also feeds on cephalopods such as squid whenever the opportunity arises.

Its diet shifts with the seasons. Pollock is most active in spring and summer, taking advantage of abundant baitfish. In the fall, it increases feeding to build energy reserves for the winter months.

Best Fishing Techniques for Cod and Pollock

Even for more experienced anglers, fishing in colder waters is often challenging. Applying the proper fishing techniques can distinguish between a frustrating day on the water and a good catch when reeling in Cod and Pollock. Here are our recommendations.

Best Techniques for Cod

Bottom fishing is the classic approach and the most commonly used technique. However, heavy lines are often used here to keep baits such as herring or squid close to the seabed, especially around rocky structures or wrecks. Another popular technique is jigging, which involves using metal jigs to imitate wounded prey or trolling with live or artificial bait.

Drift fishing is an excellent technique, as it allows for a natural presentation of the bait in areas with strong currents. Live bait, like small mackerel, can significantly improve your catch rate. Since Cod likes to scramble around structures and wrecks, using a fish finder is a good option.

Best Techniques for Pollock

Two trolling fishing rods are attached to a moving boat in inshore waters.

Jigging is primarily used to catch Pollock successfully. In this technique, fishermen drop metal jigs on the seabed and pull them out with fast, erratic movements, attracting Pollock. Trolling also works well for Pollock, especially with live bait fish at different depths and easy-to-locate schools of Pollock. Bottom fishing is another viable technique, especially in rocky or sandy habitats, where bait such as herring or sand eel is used.

Drift fishing, which involves letting your boat drift naturally with the current as you bait in, will be helpful, especially with strong tidal currents. Stick to live baits, as Pollock is attracted to the natural movement of live prey. The season is the same as for Cod. Watch out during the spring and summer when the prey is plentiful, so who knows, you might get lucky and catch both in one go.

Choosing the Right Gear for Cod and Pollock

Choosing the right equipment for these fish means finding a balance between strength and lightness, your style, their favorite food, their character, and the season when you hunt them. It is not easy, so we will give you some tips.

Best Gear for Cod

Codfish are not the fastest swimmers, but their size and strength can easily damage low-quality gear. Found in deep waters around wrecks and rocky bottoms, they require a strategic approach and reliable equipment. Let's break down the essential gear for landing them.

  • Medium to Heavy Rods: Choose a sturdy 7 to 8-foot rod that is strong enough and sensitive enough to handle the weight of cod effectively.
  • Conventional Reel: A solid conventional reel guarantees the strength, ease of handling, and durability required for Cod fishing.
  • Braided Line: 30 to 50 lb is sufficiently sensitive and durable in heavy waters.
  • Heavy Jigs: To lure Cod out of the shelter, use 6 to 16-ounce jigs or hooks rigged with fresh bait, such as herring or squid.

This setup will provide technical stability and enough skill to provide precision, control, and an exciting fishing experience.

Best Gear for Pollock

Pollock compensates for the lack of elegance with the briskness of character and acrobatic fights, which makes them actual exhibitions of the icy seas. A fan of shallow and deep waters, Pollock often schools around structures and follows strong currents, and according to such a habitat and pattern, our equipment recommendations are as follows.

  • Medium Rods: A 6 to 7-foot medium-action rod balances sensitivity and strength and allows you to feel every bite.
  • Spinning Reel: A high-quality spinning reel is essential for versatility and control. It allows for quick retrieves and smooth handling when reeling these lively fish.
  • Braided Line: 15 to 30lb braided line has enough sensitivity and strength to ensure you can detect bites and withstand the energetic pulls of these fish.
  • Metal Jigs or Soft Plastics: 1 to 3-ounce metal jigs or soft plastic lures are the best choice because Pollocks are especially sensitive to erratic presentations.

This gear choice should make you feel safe and secure in your performance. Of course, you can always add or change it according to your style and experience.

Flavor Insights and Cooking Techniques for Cod and Pollock

Lovers of fish meat and fish specialties will be satisfied here. Both fish are delicious; you won't regret having them on your dining table.

Cod: Taste and Popular Cooking Method

Cod is a famous culinary delicacy, and one of the main reasons it is caught is its culinary power. It has a mild, fluffy white flesh, making it a favorite among seafood lovers and chefs; its delicate flavor profile allows it to absorb various spices and marinades, making it incredibly versatile in the kitchen. 

The primary preparation method is baking because this method preserves the fish's natural moisture and, at the same time, enables aromatic infusions. It is enough to marinate the meat in olive oil, garlic, lemon juice, and herbs before baking at a moderate temperature until they fall apart with a fork.

Cod is also often battered and deep-fried to create a crispy exterior. This method is prevalent in dishes such as fish and chips, where Cod is paired with crispy fries and tartar sauce. It is useful even for barbecue gatherings. The versatile nature of Cod in cooking makes it a prominent part of many kitchens worldwide and accessible to everyone.

Pollock: Taste and Popular Cooking Method

With a slightly richer taste than Cod, a mild flavor, and a firm, flaky texture, Pollock is suitable for various culinary applications. It often shines in numerous recipes while complementing several ingredients and spices. Pollock is chiefly baked. When seasoned with a mixture of herbs, lemon, and olive oil, Pollock filets can be perfectly grilled and go well with roasted vegetables or grains.

Frying is another favorite technique, especially when preparing dishes like tacos, where the crispness of the batter or breading provides a wonderful contrast to the moist fish. Grilled Pollock is also a fantastic option, with the fish pre-marinated in soy sauce, ginger, and garlic. It is also used in fish sandwiches and soups, and its adaptability in the kitchen and unique taste solidify Pollock's position as a favorite seafood choice for many.

Selecting the Right Fish

Cod or Pollock, or both, whichever fish you prefer, is undoubtedly because of a particular benefit: a beginner's hunt, a tasty meal, or an exciting catch. Find out below what Cod and Pollock bring to beginners and what to experienced anglers.

Beginners Level

Throughout history, overfishing has had a particular impact on the reduction of the Cod population. This has led to stricter regulations regarding the catch limits and closed seasons, and each region has its own rules. 

Pollock is not endangered like Cod, but it is monitored and often subject to regulations to prevent overfishing, especially in commercial fisheries. Fishing quotas and limits are often implemented to protect species and maintain healthy populations.

For all these efforts to be meaningful, anglers and commercial fishermen must be informed of local regulations, obey bans, and follow catch limits. This will ensure that the balance of the abundance of these fish is not disturbed, nor will it disturb the complex ecosystem in which these fish are networked.

Current Conservation Efforts for Cod and Pollock

Current Cod and Pollock conservation efforts focus on supporting sustainable fishing practices and rebuilding stocks, mainly Cod. Many countries have introduced strict catch, size, and no-take zones to help rebuild Cod stocks. The International Council for the Exploration of the Sea (ICES) aims to monitor and regulate fishing pressure, as does the New England Fisheries Management Council in the US, which implements similar measures.

Pollock is managed through sustainable quotas and bycatch reduction techniques, including catch limits, reducing impact on the seabed, and protecting habitat areas. These efforts are crucial to ensuring the long-term health and stability of both fish populations.

How to Contribute to Conservation Efforts 

Anglers can contribute relatively simply and significantly to conservation by responsible fishing. It may seem like a small step, but it means a lot globally. Adhering to local regulations, catch limits, and size limits and having permits helps prevent overfishing, while practicing catch-and-release with proper techniques significantly reduces damage to fish populations.

You can always get involved in local organizations that care for fishing, promote more responsible fishing, and report abuse. This is the only way, in addition to the regulations, it is possible to maintain the abundance of both fish.
