The fishes are mostly bred artificially, in ponds and paddy fields. Breeding aquarium fish and also catching them in their natural habitat is an important industry sector, which yielded US$367,000 from 2008 export sales only, mostly to Japan and Middle East. A substantial part of other Bogor production, 144 billion IDR in 2008, is exported. Examples are clothes and footwear (to US, EU, ASEAN, Canada, Australia, Russia), textiles (US, New Zealand), furniture (South Korea), car tires (ASEAN countries and South America), toys and souvenirs (Japan, Germany, Brazil), soft drinks (ASEAN countries and Middle East). Most of the local sells are carried out via the eight major shopping centers, nine supermarkets and seven major markets. Transport Bogor is a major transport center of Java.
