The Banggai Cardinalfish (Pterapogon kauderni) is a species of reef fish endemic to the Banggai Archipelago in Central Sulawesi, Indonesia, and has a very limited geographical range. The Banggai Archipelago consists of 123 islands with a total area of 22,042.56 km2 and 18,828.10 km2 of marine areas. The species is a popular marine aquarium fish that has been exploited for overseas markets since the mid-1990s. The overharvest of this species for the aquarium trade has led to concerns that it will become extinct. The species is listed by IUCN as endangered and is the first marine aquarium fish to have become an international CITES issue, because of concerns that over-collection is leading to its extinction. Some captive breeding of this species has occurred, but wild stocks are still threatened.
Since 2010, LINI has worked with local communities and local Government in Banggai to support the conservation of this species through education and awareness, and the protection of wild Banggai Cardinalfishpopulations and habitats in the Banggai Archipelago.
