Abstract
Corbicula fluminea (Müller, 1774) is an Asian freshwater clam that is widely distributed throughout the world through multiple introductions. Its invasion can cause environmental and economic damage. In Brazil, C. fluminea is recorded in all major hydrographic basins. Here, we report the first record of C. fluminea in the Chapada dos Veadeiros region of Goiás, Brazil. This new record extends the known distribution of this species to a conserved area in the Cerrado biome, towards areas of interest for conservation and integral protection units of the biodiversity.
Highlights
The Golden Clam, Corbicula fluminea (Müller, 1774) is a freshwater bivalve mollusk native to South and East Asia
We report a new record of Corbicula fluminea in the Tocantinzinho River
This new record represents the first of this invasive species from the Chapada dos Veadeiros region, in Colinas do Sul municipality, Goiás state. This region is within the Pouso Alto Environmental Protection Area near Chapada dos Veadeiros Nacional Park. This new record expands the distribution of C. fluminea by at least 200 km southeast of the first records of this species in the Basin of the Tocantinzinho River, which were mainly associated with the Serra da Mesa Reservoir (Thiengo et al 2005)
Summary
The Golden Clam, Corbicula fluminea (Müller, 1774) is a freshwater bivalve mollusk native to South and East Asia (southeastern Russia, Thailand, Philippines, China, Taiwan, Korea, and Japan). It is considered an alien invasive species (AIS) worldwide (Santos et al 2012). Haag et al (2020) found that C. fluminea can be a major factor in the decline of native populations of freshwater mussels worldwide. This is the most important AIS in the conservation perspective for riverine ecosystems due to its high invasive potential (Leal et al 2021). Not known for Brazil, the economic costs have probably been similar
