Introduction
Sightings of humpback whales off the coast of Rio de Janeiro are surging as these marine giants recover from the decline caused by commercial whaling. This increase has fueled the demand for whale-watching excursions, allowing nature enthusiasts to spot these majestic animals during their annual migration.
The Recovery of Humpback Whales
According to Enrico Marcovaldi, co-founder of the Humpback Whale Project, the population of these whales has jumped from around 2,000 to approximately 35,000 in about 40 years, a number close to what existed before commercial whaling. This means they are being spotted more frequently in Rio's iconic Guanabara Bay.
“It’s wonderful. It shows that the whales are making a recovery, are healthy and thriving, and hopefully they’ll continue to do so,” said Marcovaldi.
The Protection of Whales
In 1982, the International Whaling Commission decided that there should be a pause in commercial whaling on all whale species and populations from the 1985/1986 season onward. This measure was crucial for the recovery of humpback whales.
Whale-Watching Tourism
Louise Raulais, who runs the Rio Ocean Club with her partner Theo Andrade, is among those who see tourism opportunities in the whales’ resurgence. This year, the company began offering sailboat trips for between five and 10 people to observe the whales.
Raulais said they always have a biologist onboard to share information, which can stimulate a desire to protect the whales and the ocean.
“These animals are so iconic and charismatic that they have the power to transform people, to change the way they see the world,” said Raulais.
Conclusion
Humpback whales are known for roaming long distances across major oceans in predictable patterns, typically following migration routes learned from their mothers. They feed on krill and small crustaceans, playing a crucial role in the marine ecosystem.
