Contrary to popular opinion, fishing isn’t just about throwing the bait into the water and waiting. It’s about meticulous planning, which includes finding out as much as you can about the species you’re targeting. So, here is a detailed mackerel vs. salmon comparison with everything you need to know about these two saltwater species for your next trip out into the open sea.

Here Are All the Main Characteristics You Should Be Aware of If You Want to Go Fishing

When it comes to saltwater fish, salmon, and mackerel are two of the most popular types out there, and they’re a treat for both experienced and amateur fishermen. They can sometimes be tricky to tell apart, so here is everything you need to know about salmon vs. mackerel appearance.

Salmon Has a Very Distinctive Appearance

As one of the most popular and sought-after types of fish, the glorious saltwater salmon is pretty distinctive and easy to spot. Their streamlined silhouette and body shape help them move quickly and seamlessly through the water. Salmon can vary a lot in size, from regular to very large, as much as five feet. Pink salmon is known as the smallest type, while the largest type is the spectacular king salmon. The largest one ever caught was 126 pounds heavy.

One of the most interesting features of salmon is their captivating coloration. When they return from the ocean to freshwater rivers and streams for spawning, their bodies undergo a remarkable transformation. Typically, they have a deep blue-green back that gradually fades into a silver or white underside, making them easy to spot.

However, during the spawning phase, their bodies take on vibrant shades of red, orange, and pink, particularly in the case of species like the iconic sockeye salmon. This vibrant display of colors not only makes them visually stunning and a real trophy for fishermen but also serves as a crucial adaptation for attracting mates and deterring predators.

Salmon possess a range of fins, each serving specific purposes. Their dorsal fin, situated on the back, provides stability during swimming, while their anal fin assists in maintaining balance. An interesting feature that makes it stand out is the adipose fin – a small, fleshy appendage located between the dorsal and caudal fins.

Salmon is known as one of the most beautiful fish – its reddish coloring is mesmerizing, and it has a smooth texture compared to other fish species. They have scales embedded in their skin, giving them extra protection but also better hydrodynamic efficiency, allowing them to move swiftly in the water.

Here’s How to Recognize Mackerel

The easiest way to recognize mackerel is by their unique body shape that allows them to be such fast swimmers. They’re typically quite small in size, usually no bigger than fourteen inches in length. Besides its silhouette, what truly makes mackerel stand out is the color of its scales.

They have a captivating iridescent blue-green back that fades into a shimmering silver belly, creating a contrast that glimmers beautifully when they dart through the water. This distinctive coloration not only serves as a form of camouflage but also adds to their allure when they are caught by anglers.

Mackerel possess a range of fins, each designed to facilitate their swift movements through the water. Their dorsal fin, located along their back, is notable for its triangular shape, which aids in stability during high-speed swimming. Another key feature is the lateral line, a sensory organ running along their sides, enabling them to detect vibrations and changes in water pressure, crucial for locating prey and avoiding predators.

While they do have small, barely discernible scales, mackerel’s skin has a smooth and sleek texture, which reduces water resistance, allowing them to glide effortlessly through the ocean’s currents.

Here’s a Comparison to Help You Tell Them Apart

While amateurs might mix these remarkable species up from time to time, they are actually very authentic on their own and can be easily recognizable. For starters, mackerel and salmon are fairly different in size, with mackerel typically being significantly smaller.

While both species have sleek scales and smooth skin, their colors are quite different – mackerel have a shimmering blue-green back transitioning into a silver belly, while salmon has a deep blue-green back that shifts to silver or white undersides or red, orange, and pink bodies, depending on the season. Take a look at this side-by-side comparison of the two types of fish.

If You Want to Catch These Remarkable Fish Species – You Have to Know Where to Look for

Arguably, the most important part of preparing for fishing is finding the right location. That doesn’t mean your fishing boat should be in the shade; that means you need to do your research and find out where you can find specific types of fish. You can’t expect to catch mackerel in a pond, so let’s explore their natural habitats.

Here’s Where to Look for Salmon

One of the reasons why fishermen love salmon so much is because it can be found almost anywhere. Salmon is an anadromous species, which means it lives both in saltwater and freshwater. It has a unique lifecycle that starts off in freshwater.

That’s where they spawn, reproduce, and grow. Once they’re fully grown, they swim away into saltwater until it’s time to reproduce, which is when they return to freshwater by swimming upstream to reach spawning grounds. So, depending on the season, you can fish for salmon in both saltwater and freshwater.

Mackerel’s Natural Habitat Is Saltwater

If you want to catch the sparkling mackerel, saltwater is where you should be. Unlike salmon, mackerel can exclusively be found in saltwater, primarily in temperate and tropical waters around the world.

They can be found in both coastal and offshore waters, often near the surface, where they can easily access their prey. These saltwater fish are known for their pelagic nature, which means they prefer the open ocean rather than coastal or bottom environments. Mackerel can also be found near structures like piers, jetties, and buoys, where they seek shelter and food, which is the ideal location for fishermen.

In Order to Catch Fish, You Need to Learn Their Feeding Habits

If you want to succeed in your hunt for salmon and mackerel, it’s vital to learn more about their feeding habits. You could be in the right spot and spend hours waiting for something to bite, but if you have the wrong kind of bait – it’s all for nothing.

Salmon Has Very Interesting Feeding Habits

As mentioned, salmon has a unique lifecycle that implies switching from saltwater to freshwater, so you can only imagine their feeding habits are very interesting and vary from season to season and their surroundings. Here are some universal baits that will improve your chances of catching salmon:

  • Live bait – Grown salmon is attracted to larger prey, which is why small fish like squid, herring, sardines, or anchovies are great baits,
  • Artificial lures (spoons, spinners, plugs),
  • Flies – Particularly effective in freshwater,
  • Salmon eggs – For freshwater season,
  • Jigs.

Mackerel’s Diet Also Varies Depending on Season

Mackerel have a diverse diet that typically includes smaller fish, squid, crustaceans, and zooplankton. Their diet can vary depending on their size and the availability of prey in their habitat. They are swift swimmers and excellent hunters.

During the summer months, mackerel feed more actively near the surface in warmer waters, while in the winter, they may move to deeper, cooler waters where they can find prey like squid. An interesting fact is that they can be nocturnal and feed during nighttime. Here are the top baits for mackerel fishing:

  • Live bait – Mackerel love to hunt smaller fish, so use bait like anchovies, sardines, or small herring to attract them,
  • Feathered jigs,
  • Flies,
  • Spinners,
  • Scented baits.

Make Sure You Have Proper Fishing Gear and Techniques

While knowing everything about a species in theory is definitely helpful, you also need to have the physical act of fishing down to a science. Different species require different equipment and techniques, so here’s everything you need to know about the best ways to catch salmon and mackerel.

Here’s All the Equipment You Need to Catch Salmon

The equipment needed to catch salmon varies depending on the surroundings and the season. In general, there is no special gear required to catch this magnificent fish. Besides your fishing rod, hook, bait, and fishing reel, you may want to add in weights, sinkers, or swivels, just in case.

Practice These Techniques If You Want to Hook Salmon

Salmon isn’t very difficult to catch, and there are many techniques that work wonders. Baitcasting is the most common technique, but fly fishing, trolling, and drift fishing are also frequently used.

Mackerel Fishing Is Easier with a Few Accessories

Most fishermen love targeting mackerel, as it’s always a guaranteed catch. While you would do just fine with your regular equipment, it can be a bit easier if you bring a few extra items, such as a landing net or a gaff. Another thing that could save you a lot of time is a fish finder – mackerels have the habit of swimming in schools, and a fish finder can help you locate them more easily.

What Fishing Techniques Could You Use for Catching Mackerel?

As mentioned before, your technique varies depending on your location. Mackerels often swim around piers or close to the shore, so casting is the best technique in those situations. Trolling is more suitable for fishing in deeper water, so if you go on a boat in the middle of the ocean – get ready for trolling. Other common techniques include jigging, live bait fishing, chumming, and the bait-and-wait method.

Culinary Uses and Flavor Profiles

Mackerel and salmon are two of the most popular fish used for cooking all over the world. They are not only delicious, but they’re incredibly healthy and filled with Omega-3 fatty acids. Both types are served in restaurants all over the world every day, and they’re definitely people pleasers. They are both very universal when it comes to cooking, but when there’s a choice between canned mackerel vs. canned salmon, we recommend mackerels.

Culinary Appeal of Mackerel

Mackerel is an incredibly popular choice in cooking. It’s a rich, savory, oily fish with a distinct strong flavor, and it’s incredibly versatile – it can be grilled, smoked, poached, broiled, and so on. The most popular way of preparing it is by grilling it after it’s been sitting in some kind of a marinade. If you like rich flavors and succulent meat, you will love mackerel. Our recommendation is to marinade it in some olive oil, lemon, parsley, and garlic and then fry it on both sides in a skillet. Bonus tip: garlic, Greek yogurt, and tahini dip would be a heavenly addition.

Salmon Is Always a Good Option

These days, you can’t seem to open a menu without at least one salmon dish popping up. It’s one of the most widely consumed fish, and with good reason. It is the ultimate fish for cooking – it’s delicious, healthy for you, and can be prepared in a million and one ways. It’s most commonly consumed as sushi, but don’t underestimate the power of a good baked salmon. However, our top choice is a poke bowl – just put some raw salmon, edamame, rice, green onion, cucumbers, and any other ingredients you like into a bowl with soy sauce and wasabi mayo.
