In a remarkable turn of events, Caleta Olivia, traditionally known for its oil industry, has emerged as a new hotspot for whale watching due to the return of the sei whales to the San Jorge Gulf. Once nearly extinct, these majestic creatures, measuring up to 18 meters and weighing over 20 tons, are making a comeback, attracting attention and fostering the growth of 'blue tourism' in the region.
Historically, sei whales vanished from these waters nearly a century ago due to commercial hunting. However, they have returned in recent decades, lured by the abundant food provided by the Gulf's macroalgae forests. According to the International Union for Conservation of Nature (IUCN), sei whales are classified as endangered but are currently experiencing population growth, with an estimated 50,000 individuals worldwide.
Research from the Center for Marine Systems Studies (CESIMAR-CONICET) and the National University of Patagonia San Juan Bosco indicates that approximately 2,600 sei whales approach the San Jorge Gulf between January and June each year.
Local authorities are actively promoting the presence of these whales as part of their strategy to enhance the city's image and stimulate economic growth through sustainable tourism. Valeria Negro, the Deputy Secretary of Tourism in Caleta Olivia, emphasized the importance of showcasing the region's marine biodiversity and the potential for 'blue tourism'—a global trend that encourages positive community engagement and long-term marine resource preservation.
Efforts are underway to establish boat tours by the end of the year, allowing visitors to observe the whales while respecting their natural habitat. The sei whales typically visit from December to June, providing ample opportunities for close encounters.
Caleta Olivia's initiative does not compete with traditional whale watching in Puerto Madryn, as different species inhabit the regions at different times of the year. The Gulf of San Jorge has been designated a 'point of hope' due to its unexploited nature, offering a sanctuary for the sei whales.
By attracting sei whales for several months each year, Caleta Olivia is poised to develop 'blue tourism,' which focuses on respecting nature while exploring the mysteries of the sea. This initiative promises to create economic opportunities for local communities, including accommodations, transportation, and recreational activities.
