Threats to the Ecology of the Biotope: The habitat of Channa limbata which is the pilot location for this biotope design is the Mount Pancar area which has the status of a Nature Tourism Park. Namely a conservation area that is also used for recreational purposes. The activities of tourists, trade and passing vehicles are feared to have a negative effect on the stability of the Channa limbata habitat.
