Baja California Sur is a popular destination for marine wildlife tourism, and for good reason. This Mexican state is home to some of the most beautiful beaches, pristine waters, and diverse marine life in the world. Among the many species that can be found in the waters off Baja California Sur is the striped marlin, or Kajikia audax. Striped marlin are known for their beautiful blue and silver stripes along their sides, as well as their long, pointed bill. They are a highly sought-after game fish, attracting ecotourists and fishermen. These fish can be found near the surface and up to depths of 500 feet and are known to migrate long distances, traveling as far as 5,000 miles. Off-shore of Puerto San Carlos is one of the best places to find striped marlin in Baja California Sur. Adults can grow up to 14 feet long and weigh up to 450 pounds, although the average size is closer to 8-10 feet and 150-200 pounds. They are a fast-swimming species, capable of reaching speeds of up to 50 miles per hour. One of the most interesting aspects of striped marlin behavior is their hunting technique whereby they take turns at attacking the baitball. They are known for their spectacular aerial displays, leaping out of the water and flipping around to stun their prey before attacking. They typically feed on small fish, squid, and crustaceans. Striped marlin can be found in the waters off Baja California Sur year-round, but the best time to catch them is between October and February. During this time, the water temperature is ideal for these fish and they are more active and easier to catch.  In addition to sport fishing, there are also opportunities to observe striped marlin in their natural habitat. La Paz Divers offers snorkeling expeditions that allow visitors to see these fish up close and personal. Swimming with striped marlin is a unique and unforgettable experience, and it is also a great way to promote conservation and educate people about the importance of protecting these fish. The striped marlin are an important and fascinating species that play a vital role in the marine ecosystem of Baja California Sur. These fish are a must-see when visiting this beautiful region.

The “Mexican sardine run”, as we like to call it, is a natural phenomenon that occurs in the waters off Baja California Sur, Mexico. It is a spectacular display of marine life in action, as millions of sardines move in massive schools along the coast, pursued by predators such as dolphins, sea lions, whales, seabirds, and of course striped marlin.  This mass migration is triggered by changes in water temperature, currents, and food availability. It is a critical event for the survival of the sardine population, as well as for the many species that rely on them for food.

The Mexican sardine run is a unique and unforgettable experience for anyone who has the opportunity to witness it.  It is not only a spectacle for tourists and nature enthusiasts, but it also has significant ecological and economic implications. The sardine population is a vital food source for many marine species, including dolphins, sharks, whales, and sea lions. It also supports a commercial fishery, providing an important source of income and food for local communities.
