In a freshwater canal surrounded by mangroves in southern Guatemala, hundreds of baby tropical gars—torpedo-shaped fish with an alligator-like snout known as the "fossil fish"—are being released into the wild. These fry were raised in tanks at the Marine Conservation Center of Guatemala City's La Aurora Zoo and then transported by boat to their natural habitat. This marks the first time the species has been raised in captivity, a significant step in efforts to protect it from threats such as illegal fishing, pollution, and extreme weather events worsened by the El Niño weather pattern. The tropical gar (Atractosteus tropicus) is considered prehistoric by scientists because it has remained largely unchanged in its physical form for 100 million years. It is a smaller relative of the alligator gar, one of the largest freshwater fish in North America. Adults can grow up to 1.2 meters (4 feet) in length and weigh about 10 kilograms (22 pounds). This fish plays "a very important role" in Guatemala's freshwater ecosystem, according to Jennifer Hernandez, deputy head of conservation at La Aurora Zoo. As a carnivorous species, it helps maintain "balance" in rivers by controlling populations of smaller aquatic animals. The tropical gar is currently designated as "vulnerable" in Guatemala, highlighting the need for conservation efforts. "It is a species that, in years to come, could reach a much more critical state," warned biologist Gaitan, emphasizing the urgency of protecting the fish's habitat and ensuring its survival. Conservationists are hopeful that the release of these young fish will contribute to stabilizing their population and preserving their role in the ecosystem. This initiative by La Aurora Zoo reflects a broader effort to address the challenges faced by native species in Guatemala. By raising and releasing tropical gars, the zoo aims to support the long-term survival of the species and raise awareness about the importance of protecting freshwater environments. The success of this project could serve as a model for similar conservation efforts in the region.
