When we say that Cape Cod is a lucrative fishing ground, we aren’t exaggerating. In fact, we might be selling it short! This place bathes in the bay, sound, and ocean waters. It’s surrounded by Cape Cod Bay to the north, the Atlantic Ocean to the east, Nantucket and Vineyard Sound to the south, and Buzzards Bay to the west.

The Atlantic Ocean is home to some of the most sought-after game fish in the world. Luckily for you, Cape Cod has clear access to it. This means that you can cast your line year-round and end up with a bragworthy story every time. But, who are the formidable opponents who call these waters home? Let’s see what Cape Cod’s offshore fishery has to offer. 

Cod

What better way to kick off the “Top Catches” section than with a true celebrity? The beloved deepwater treasure of Massachusetts is without a doubt Atlantic Cod. Their importance is so steeped in the history of the state that one of Massachusetts’s nicknames is the “Codfish State.” Even Cape Cod stands for “a great store of Codfish.” But, what makes them so cherished here?

The immediate answer would be their table fare qualities. If you’re looking for a mouth-watering delicacy, Cod are your go-to dish. Their milky flavor is what every seafood gourmet is looking for. Then again, a finger-licking taste isn’t the only trait Cod are famous for. The locals will testify about their fighting abilities, too. Tasty and feisty, Cod guarantee a fun day out in the open.

While Cape Cod’s fishing season runs mostly from May through November, Cod angling is a year-round activity. You’ll be also pleased to hear that these bottom dwellers are omnivorous and they’ll bite just about anything you throw at them. 

Haddock and Pollock

Cod’s relatives Haddock and Pollock deserve VIP spots as well. Similar to their famous cousin, these guys navigate the bottom areas in search of food. You can usually find them in depths up to 500 feet! Lure them with juicy seaworms and clams, and you’ll feel a bite before you know it. Once you have them hooked, enjoy reeling these delicious treats in!

While closely related to Cod, Haddock and Pollock are slightly different. Cod are larger and more embellished than their somewhat smaller and paler kin. Haddock are further distinguished from Cod and Pollock by an eye-catching black lateral line. Additionally, while you can target Cod throughout the entire year, Haddock and Pollock fishing is more seasonal and thrives in May and October.

Tuna

Once you warm up with the Cod family, you’re then ready for a serious backbreaking battle. And, who better than Tuna to make you break a sweat? Deep sea fishing in Cape Cod is blessed with Bluefin and Yellowfin Tuna. Clashing with these titans will put every single muscle in your body to the test. But that’s exactly what you’ve been looking for, isn’t it?

Bluefin and Yellowfin Tuna are migratory species and the best time to go after them from Cape Cod is during summer and fall. Both species are considered to be prestigious game fish, but Bluefin Tuna are the ones that rule Massachusetts’s waters. As the biggest and most thrilling sea creatures around here, they’re the absolute royals of deep sea fishing in Cape Cod.

Sharks

If you’re yearning for the ultimate adrenaline rush, then a Shark trip is your ideal bluewater fishing adventure. You can cross paths with Porbeagle and Thresher Sharks, but Shortfin Mako and Blue Sharks are the fierce predators who dominate these waters. Both are extremely exciting game fish and thus very popular among recreational anglers.

Mako Sharks are aggressive and ferocious rivals that we know you’ll want at the end of your line. However, they’re also exceptionally intelligent and unpredictable, and even seasoned anglers find them challenging. So, make sure you’re in experienced company when hunting them down. Outwit and overpower Sharks and you’ll feel truly glorious.

… And More!

By now you’re thinking that Cape Cod has something for everyone. And you’re absolutely right. Cod, Pollock, Haddock, Tunas, and Sharks are a versatile group of deep sea locals. Yet, the list of residents doesn’t end there. It expands to include an even more diverse game fish circle. False Albacore, also known as Little Tunny, Atlantic Mackerel, Halibut, and Marlin are happy to join the already notable crew.

We praise Cape Cod’s waters for a reason. Not only can you go after Tunas and Sharks, but you can also test your skill against the world’s prominent game fish like Marlin. The truth is that you can wet your line anywhere from Georges Bank to Stellwagen Bank and come out victorious. 

There’s no shortage of fish trophies, especially during summer. If you aren’t sure what method will guarantee success, our next section comes to the rescue.

How to Go Deep Sea Fishing in Cape Cod

Deep sea fishing isn’t as tough as it’s puzzling in terms of not knowing where to look for your prize and how to go after it. Once you figure out the hotspots and fishing techniques, there’s no limit to what you can catch. We’ll gladly share our expertise with you, but the greatest way to experience Cape Cod to its fullest is by hiring a local guide.

Cape Cod fishing charters live and breathe these waters. There’s no one better than Cape Cod captains to show you around. They’ll take you where the fish are biting and help you fight those beasts on your own terms. So, hit them up for the time of your life! Meanwhile, we’ll do our best to outline the most productive methods to do so. Later on, we’ll recommend some prime fishing spots as well.

Trolling

Trolling is the queen of deep sea fishing techniques. It’s by far the most effective method and you’ll also want to combine it with other strategies to maximize your chances of success. Spice up your angling approach with trolling and you’ll rarely end up empty-handed. Another good news is that trolling is fairly easy, so it’s suitable for both professionals and novices alike.

The main idea behind trolling is to lure your predator by imitating its prey. Now, depending on whether you’re pursuing Sharks or Pollock you’ll use different bait, of course. But the bottom line is that it has to look real, or otherwise your target won’t buy it. 

Another crucial aspect of making it look real is speed. Marlin aren’t picky, and both high and low-speed trolling will make them chase you, whereas Tuna prefer fast-moving lures. Then again, you can always consult with your captain to see what works best at that very moment.

Bottom Fishing

While trolling is an insanely prolific approach for most pelagic fish, some deep sea creatures are bottom dwellers and would rather have their food dropped to them. This is when bottom fishing enters the scene. Species like Halibut and Haddock love gravel and you can always find them in the deeper waters. So, if you’re looking to score them, bottom fishing is your go-to method.

Bottom fishing is a smart way of luring the fish from their depths. Once you locate them with fishfinder equipment, the fun can start. To ensure your line sinks properly, you have to attach a weight to it. This will allow your line to extend downwards and reach your bottom predator. Hook it and it’s reeling time!

Chumming

If you’re after Tunas and Sharks, chumming is your friend. This method has been around for ages and it works like a charm with these large deep sea monsters. Chumming is essentially an attention-grabber. It’s the practice of throwing ground bait in the water with the single goal of attracting your target. Tempting chum lures out your giants and announces reel-screaming action.

Along with chumming, you can also try chunking. Both techniques proved time and again to be fruitful with Tuna. You can use both on the same outing or combine them with other fishing approaches to increase the likelihood of landing a prize catch. After all, that’s exactly what deep sea fishing is all about – possibilities! You can mix and match until you hit the jackpot.
