This photo was taken in a tank trout farm located in Cundinamarca Department, Colombia.
The rainbow trout, Oncorhynchus mykiss was introduced into Colombia in 1939 for the purpose of the stocking in natural water bodies and support sport fishing. Afterwards, the local preference to trout encouraged the establishment of trout farming at different levels.
Colombia’s trout farming is distributed among several of the country’s departments. However, because of temperature requirement, it is based in areas 1,900- 3,200 m above sea level with annual temperatures of 10- 17° C. Cundinamarca is one of the main Colombian departments where the culture of trout is being practiced.
The eyed ova of rainbow trout used in fish farms are mainly are imported from the United States; in 2005, estimated eyed egg imports reached 28 million.
Typically, the production cycle lasts 10-12 months, during which high quality feed is used ending by production which could range from 20-50 kg/m3. However, in some advanced operations, much higher production of larger average size fish has been attained during reduced growing season. Commercial trout operations can export their products to the U.S. and Germany.
