Building on the work of the IUCN/SSC Conservation Breeding Specialist Group Conservation and Management Planning workshop in 2000, 100 species of freshwater fish endemic to Madagascar were assessed and mapped. Alarmingly 54% of these species were found to be threatened and a further 4% are already Extinct. This is the highest level of threat recorded for any other similar taxonomic grouping within the IUCN Red List. The report was completed in September 2004 and has been submitted to Conservation International to feed into their ongoing conservation programme in Madagascar.
