Invasive Species Threaten Brazil's Bay of All Saints
Invasive Species Threaten Bay of All Saints Ecosystem in Bahia, Brazil The Bay of All Saints, Brazil's largest and the world's second-largest bay, faces a growing threat from invasive exotic species. A recent study by researchers identified 36 such species, disrupting the delicate balance of the marine ecosystem. Four species are of particular concern: Sun coral, soft coral, siri-bidu crab, and lionfish. "These invasive species are not part of the region's biodiversity and threaten the environmental equilibrium," explains a researcher involved in the study. The Sun coral, originating from the Indo-Pacific Ocean, releases chemicals and crushes native corals. The soft coral, from the Caribbean, forms thick mats that dominate the reef. The siri-bidu crab is known for destroying mangroves and competes with native species for food. The lionfish, a voracious predator with venomous spines, poses a danger to humans. A task force of researchers from the Federal University of Bahia (UFBA), the Bahia Environment Secretariat (SEMA), and the Promar NGO is actively monitoring the situation and implementing projects to control the spread of these invasive species. The long-term impacts are still being assessed, but the immediate effects on local ecosystems and artisanal fishing are evident. The Bay of All Saints is a vital ecosystem supporting a significant population. The ongoing efforts to control these invasive species are crucial to preserving its biodiversity and the livelihoods of those who depend on it.
