BEHAVIOR AND RESPONSE OF JAPANESE CATFISH (Silurus asotus) IN CAPTIVITY PROVIDED WITH AN ARTIFICIAL MICROHABITAT MOSAIC
Abstract
Rearing of Japanese catfish (Silurus asotus) requires special considerations for designing of
facilities and management. Information on its biology in natural environment
provides ideas for developing suitable culture systems. For this species,
underwater artificial microhabitat structures are needed to perform its normal
behavior. The fish shows distinct preferences for some designs based on visual
cues and its decision to make use of these structures is guided by other cues
probably related to light and water flow. Microhabitat structures can make a
real difference to managing stress of captivity in this species. Absence of a
suitable structure causes ‘habitat bottleneck’ that develops aggressive
behavior. However, the intraspecific antagonistic behavior gives way to social tolerance among conspecifics.
Microhabitat metrics is important in addition to physical attributes of the
structure so as to allow social grouping in the fish under favorable
conditions.
