Notes on the distribution of invasive freshwater snail Pomacea Canaliculata (lamarck, 1822) and P. Insularum (D'orbigny, 1835) in Indonesia

Abstract

The freshwater snails Pomacea canaliculata and P. insularum have been reported as important invasive species causing damage to crops and predominantly wetland rice in Asia. These snails are known as "Golden Apple Snail" (GAS), an introduced species from Argentina. Pomacea canaliculata or known as "keong mas, keongmurbei" was introduced in Indonesia around 1983, and after more than 20 years, it now can be found very abundant at various habitats such as marshes, ponds, irrigations, lakes and rice fields in almost all places in Indonesia. Based on the collections of these snails deposited in the MZB (Museum Zoologicum Bogoriense, Research Center for Biology) and secondary data (references), the distribution of these two snails was studied. Pomacea canaliculata is widely distributed, while P. insularum is only found at Lake Semayang and Lake Balikpapan in Kalimantan. The distribution map is presented and will be useful as a basic information to manage these invasive snails.
