Best Fish to Catch in Mexico

As the fishing is so diverse, the list of species you can catch is almost endless! Some of the world’s favorite fish are available across the country, no matter which waters you’re casting a line in. Here’s our pick of the best:

Top Freshwater Catches

While no freshwater fish made the pick of the bunch above, that doesn’t mean they don’t deserve more than just an honorable mention. Across Mexico’s streams and lakes, there’s a whole host of battle-worthy and delicious fish for you to take on. Here are a few of them:

• Bass. Everyone’s favorite freshwater fish, Largemouth Bass, is abundant in Mexico. The best spots to cast your line are the lakes in Sinaloa, such as El Salto or Lake Baccarac. Or, head over to the northwest, where Lakes Guerrero and El Cuchillo are your go-to spots. You can explore your chosen lake with a guide or fish from shore. The results will be great, either way.
• Trout. Fly fishing anglers will love the Trout fishing on offer in Mexico – especially as so few people know about it. Whether up in the Sierra Nevada’s mountain streams or cloud forest lakes across the country, there’s plenty of action to be had by going after a number of exotic Mexican Trout, such as the Piaxta and Acaponeta varieties.
• Catfish. You probably know that the Rio Grande holds good Catfish opportunities but these creatures inhabit plenty more diverse streams and lakes across the country. Lake Dominguez in Sinaloa is one of the best Catfish lakes in the world, while there’s even a Cafish native to the state of Chiapas! There’s everything from Cats weighing just a couple of pounds up to 50 pounders, so there’s something for everyone.
• Tilapia. If you’re looking for some meat on your Mexican freshwater fishing trip, then you’ll want to target Tilapia. Now thriving across the country, these delicious creatures are a joy to behold for more reasons than just their taste. They’re fun to target, grow to big sizes, and also provide a challenge to keep on your line, as they have very soft lips. And, in a lot of lakes – especially inland – they’re invasive. By going after them, you’ll be doing the environment a favor!

While these are the stars of the show, there’s a worthy supporting cast that deserves your attention, too. Carp are an often-overlooked fish to target in the US but, left to their own devices in the wilderness, they can grow to seriously impressive sizes. And there are also other interesting species, like Alligator Gar, on offer. All in all, you won’t be lacking for rivals when freshwater fishing in Mexico.

Top Inshore and Nearshore Catches

Things really start heating up when you head into the saltwater realm, however. With warm bays and productive reefs on both of Mexico’s coasts, there’s a world of prized fish to target just a short hop from shore.

• Bonefish. While these creatures may be small, they’re among the best pound-for-pound fighters out there. Fly anglers, in particular, enjoy going after these silvery speedsters in the flats, but spinning gear can also do the trick. Head to the clear inshore waters anywhere on the Yucatan peninsula and you can test your skills against these beauties.
• Roosterfish. Over to the Pacific, and the Sea of Cortez is where you want to be for some unique fishing opportunities. You can only target the dazzling Roosterfish from Baja California Sur down to Costa Rica, and you don’t want to miss out on the chance to do so. Picture-perfect and tough-fighting to boot, they’re a serious rival. Just make sure to practice catch and release, so these brutes can do battle once more.
• Tarpon. Speaking of tough fighters, few species in the world put up a battle as strong as Tarpon. And Mexico just happens to offer some of the best fishing grounds in the world for them. Get ready to “bow to the King” on an inshore trip all around the Yucatan Peninsula. Head south of Cancun to Ascension Bay for the biggest creatures, or north to Holbox for juvenile Tarpon. You can also target them in Baja California and Tabasco’s inshore waters.
• Snappers. Reef fishing almost everywhere in the world is synonymous with Snapper fishing, and Mexico is no different. Whether nearshore in Cabo San Lucas, Puerto Vallarta, Acapulco, or out in the Gulf of Mexico or Caribbean, there’s a Snapper with your name on it. Cubera Snappers are the most common opponent you’ll come up against, but there are 26 Snapper species in total here.
• Yellowtail Amberjack. If you’re fishing in Mexico’s Pacific waters, there’s a good chance you’ll test your skills against a Yellowtail or two. These dazzling creatures are quick and strong, and you can land them by trolling or bottom fishing. They’re abundant all around Baja California and the Sea of Cortez, and promise a tasty treat for you to enjoy after a solid angling workout.

We could have dedicated an entire article to both inshore and nearshore catches. But you probably understand why we decided to focus on these fish above. We have to mention some of their neighbors, however, with Permit, Jack Crevalle, and Snook on offer inshore, depending on where you are. Hit the reefs and Groupers, Kingfish, Barracuda, Amberjack, and much more could be in the cards. Pretty impressive, right?

Top Offshore Catches

But if you’re looking for a real bucket-list fishing adventure, you’ll want to head offshore. Whether out in the heart of the Pacific or up in the Gulf or Caribbean, there’s an enviable list of fish to target. Get ready for the battle of a lifetime when you come into contact with the following:

• Mahi Mahi. Known as “Dorado” in Spanish, these beautiful creatures are also fun to target, and taste delicious. They’re an all-round catch, and you can find them in the Pacific and Atlantic. Try trolling to get their attention before they rush away with your line. They’ll tire after a while, but you’ll still have to work hard to land one aboard.
• Sailfish. Just like Mahi Mahi, Sailfish are possible on both sides of the country, with the waters off Baja California Sur proving to be particularly fruitful when the season hits. Awe-inspiring with their size and stunning sail (hence their name), they’ll also thrash about in an attempt to break free from your hold. You’d better be prepared for a lengthy battle to reel one in, but the memories you’ll make are sure to last a lifetime.
• Tuna. If there’s one fish that needs no introduction, it’s Tuna. Beloved all around the world for their quality meat, they’re also a key staple of Mexico’s rich cuisine. Four kinds of Tuna are prominent in Mexico’s waters – Skipjack, Blackfin, Yellowfin, and Bluefin – and they all make for a tasty treat. But don’t discount their game qualities! These fish are cold-blooded, meaning they can dive deep with your line, making you work for every inch of it.
• Marlin. Only one species can top Tuna for being on every deep sea angler’s bucket list. We’re talking about Marlin, of course. Famous for their acrobatic leaps out of the water, they’re among the toughest fish in the world to land. And, in Mexico, they grow to over 1,000 pounds! Blue, Black, and White Marlin are available depending on where you are, with Blue Marlin in Cabo San Lucas being the largest. Good luck if you encounter one, that’s all we can say!

That list should already have got your pulses racing. If not, there are many more monster fish offshore from both Mexico’s coasts for you to battle. Wahoo swim in the same waters as Mahi Mahi, while the further out you go, Swordfish are also possible. One thing’s for sure, you’re in for a thrilling adventure when offshore fishing in Mexico.

When to Go Fishing in Mexico

Mexico is big. We don’t need to tell you that. And with an ocean on either side, it’s pretty tricky to come up with a definitive guide to fishing seasons for the whole country. Hone in closer with our guides to fishing seasons in Cancun and Cabo for an idea of what you can catch and when at either end of the country. Or, have a look below at what’s biting across the whole of Mexico.

With good weather year-round, there’s always something biting – as you can see above. But, each species has its own peak season. For the best chance at a mixed bag, come from spring through fall. However, spring and fall also offer the best freshwater fishing. And, if you’re looking for some winter sun, you can pair your vacation with a fishing trip to make all your dreams come true.

How to Go Fishing in Mexico

No matter where you decide to go for your Mexico fishing adventure, there’ll be a range of techniques to try out. The locals will have their own tried and true methods, and you’re welcome to go about casting a line in whatever way you usually do, too. However, here are some popular methods of landing fish in Mexico to get you started…

• Fly fishing. From the mountain streams to the backcountry waters of Cozumel, all the way out to the deep waters of the Pacific and Gulf of Mexico, fly fishing is an exhilarating experience. The usual rules apply when it comes to gear. 6–8 wt rods will do the trick on the flats and inland, while you’ll need at least a 14 wt stick if going for the pelagics offshore. As anything from Trout to Bonefish, Tarpon, Tuna, and Billfish is in the cards, depending on where you go, diversity is the name of the game when it comes to your flies.
• Spearfishing. Wanting to get the pulses racing that little bit more? Spearfishing in Mexico is sure to deliver. From the dazzling reefs to the open bluewaters, there are plenty of opportunities for you to come face-to-gill with some of Mexico’s most prized fish. Just beware that spearing here can be done only by free diving, so there’ll be no tanks allowed. But don’t worry, there are plenty of guides ready to take you to land fish like Grouper, Snapper, Permit, Mahi Mahi, and even Tuna!
• Deep sea fishing. There are few better places in the world than Mexico to experience deep sea fishing. With two oceans at your disposal, there’s an almost endless list of pelagic fish to target. And, what’s better, Mexico really makes the most of it. All the resort towns, such as Cabo San Lucas and Cancun, boast excellent deep sea angling options, where you can go after Mahi Mahi, Sailfish Tuna, Marlin, and much more. Trust us when we say you’ll be back for more.

Mexico Fishing Trips

You should have already got the memo that fishing in Mexico is diverse. That means that there’s a whole range of trips on offer. You can escape from the hustle and bustle of everyday life with a trek to some mountain streams for some freshwater shore fishing. If you’d like more action, you can head out to the deep ocean waters for multiple nights. And with everything in between catered for, you know there’s something for you.

We suggest that beginners and families try inshore or reef fishing trips that last up to 6 hours, with 8+ hour trips reserved for more advanced anglers. But, with such rich deep sea fishing grounds close to shore, you could even try your hand at a Marlin on a half-day excursion, especially in Baja California Sur.

Mexico Fishing Regulations

In Mexico, persons of all ages (including children) who are on a fishing boat need a sportfishing license, even if they’re not fishing. This goes for freshwater and saltwater fishing. Licenses aren’t difficult to obtain and can be purchased online. The most efficient way (and most convenient if you speak English) is to get it from the BCS government website.

Despite this, many charter captains will offer to purchase licenses for those on board. And, in even better news, fishing from shore or a pier doesn’t require a license at all! Just beware that you’ll need to be at least 250 meters (800 feet) from any swimmers when casting your line.

You should also be aware of bag limits. Every angler can bring up to 10 fish back to shore from saltwater adventures. However, there can only be a maximum of five of each species. One Billfish counts as five fish, and you may only take one back to shore. Freshwater fishing regulations stand at half those of saltwater, so five fish per angler is the limit.
