Breakthrough of Arowana (Scleropages formosus Schlegel & Mèler, 1844)Breeding

Research Project “Arowana (Scleropages formosus Schlegel & Mèler, 1844)Breeding” undertaken by Yangtze River Fisheries Research Institute (YRFRI) achieved breakthroughs after years of endeavors. The first brood of arowana fries was got (Picture 3) in the laboratory on Nov. 1 2007. A total of 10 arowana fries survive in the aquarium (Picture 1).

Arowanas(Scleropages formosus Schlegel & Mèler, 1844) are freshwater bony fish, sometimes known as “dragon arowanas” or “bony tongues”. The species include cross-back golden arowana, red arowana, green arowana, etc. The bred cross-back golden arowana successfully this time is one of the most expensive species (Picture 2), and its juvenile price could reaches 300 USD.

Arowanas native in Malaysia, Indonesia and Sumatra Island has become ornament fish since the mid of last century. Arowanas has elongate bodies with heavy, armor-like scales, shining skin and mosaic pattern of canals. Due to its unusual appearance and characteristics, the arowana is highly sought out and one of the most rare ornament fishes. However, as a result of overexploitation of resources, it is listed as the endangered species. The successful breeding means that wild F2 offspring propagation has gained momentous progress and it is expected to release the pressures of endangered wild species.
