1/9/2024 0 Comments Rare freshwater fishMangut fish, biogeographically, is spread in Sumatra, Kalimantan and West Java. This fact inspired freshwater fish researchers from Universitas Airlangga Surabaya in collaboration with researchers from Brawijaya University Malang to find out more about the current condition of freshwater fish diversity, especially in Java. The results of these studies showed new facts that fish which were limited and only found in certain regions were also scattered in other regions. In this article the freshwater fish species that will specifically be discussed is Lobocheilos falcifer, in the local language called Mangut fish. This fish has similar physical characteristics with Tawes fish( Barbonymus gonionotus ) but it has several pore protrusions in the muzzle and the mouth is underneath. In general, the body of Mangut fish is silver. Since western Indonesia is divided into several islands due to the rising sea levels from the melting ice in poles, many freshwater fish species are isolated in an area and their distribution is limited. The existence of freshwater fish has long been used by the community as a source of protein. But some of them are less concerned about the condition of each species. As long as they are fish, people tend to take them without regard to their conservation status. For example, Javanese Belida fish ( Notopterus notopterus ) which has been protected by the Indonesian government for a long time since 1999 but the practice of catching it continues to this day. Therefore, studies should be conducted to save the existence of these species. It is natural because Indonesia is located in a tropical region located between Asia and Australia so Indonesia has a unique freshwater fish species that are not found in other regions. Indonesia’s freshwater biodiversity is one of the largest in the world.
