December 20, 2010 : Giant Barb
The giant barb or Siamese giant carp, Catlocarpio siamensis (Thai: กระโห้ or กะมัน), is the largest species of carp in the world. These migratory fish are found only in the Mae Klong, Mekong and Chao Phraya river basins. This fish is a desirable food fish, which may have caused a serious decline in its numbers.
They are usually seen in the big pools along the edges of large rivers, but will seasonally enter smaller canals, floodplains and flooded forests. Young barbs are usually found in smaller tributaries and swamps, but can acclimatize to living in ponds, canals and swamps. The fish generally live in pairs.
These are migratory fish, swimming to favorable areas for feeding and breeding in different parts of the year.
These slow-moving fish subsist on algae, phytoplankton and fruits of inundated terrestrial plants, rarely (if ever) feeding on active animals. In the lower Mekong basin, young giant barbs have been reported as occurring primarily in October.
