Mud fishes
are well known for their cannibalistic behaviours. This is mostly exhibited by Heterobranchus
species followed by heteroclarias and lastly clarias.
However, cannibalism can
be greatly reduced by frequent feeding and sorting. Cannibalism is more
pronounced when the fishes are very young.
It is suggested that be sorted at
least every week from fry, fingerlings and post fingerlings stages.
The shooter
(bigger ones) packed in the same tank should also be sorted weekly in the same
line with the smaller size batches. The tank could be partitioned with net
screens.
