Captive breeding
Since the Siamese fighting fish ("Betta splendens") was first successfully bred in France in 1893, captive spawning and brooding techniques used in aquaculture have slowly improved. Captive breeding for aquaria is concentrated in southern Florida, Singapore, Hong Kong and Bangkok, with smaller industries in Hawaii and Sri Lanka. Captive breeding of marine organisms has been in development since the mid-1990s. Breeding for freshwater species is more advanced than for saltwater species. Currently, only a few captive-bred marine species are in the trade, including clownfish, damselfish, and dwarf angelfish.
