MEKONG GIANT SALMON CARP
(AAPTOSYAX GRYPUS)
POPULATION TREND
The species was once widespread in the mainstream Mekong River, but naturally rare and has beenmuch reduced in recent years. Its range has reduced and now larger individuals are very rarely found. It is rare in Lao PDR, and has likely disappeared fromThailand. Its population has reduced over the last decade by more than 90% as a result of overfishing and habitat degradation.
HABITAT
The species mainly inhabitsmainstreams, and frequently enter large tributaries. Breeds in summer, in clear water around rocky rapids in the Thai-Lao border. Breeds in faster flowingwater/rapids.
DISTRIBUTION
The Mekong Giant Salmon Carp has a wide range within the Mekong River, but is now present at very low densities in both adult and juvenileforms. Its population has been much reduced (by more than 90%) over the last decade (C. Vidthayanon, pers. comm.), as a result of overfishing and habitat degradation.The species is therefore assessed as Critically Endangered. This fish is also likely to be impacted in the future by development of mainstream dams, which willfurther limit its breeding success.
THREATS
Local overfishing (especially through drift gill nets), illegal fishing (explosives) impact its populations, andhydrographic change due to mainstream dams and climate change threaten its survival and recruitment. There are three further dams planned in the Thai part of the Mekong,within the species current distribution.
