This is the first report on the rearing of larvae under
captive conditions of the farm bred population of
C chitala in a recirculatory system. The study showed
differences in the growth, SGR and survival of C. chitala
fed on the same level of different diets in the
recirculatory system having similar environmental conditions.
However, many factors are related to the feeding
such as stocking density, production system, type and
size of rearing tanks, size of fish and quality and quantity
of food (Mgaya and Mercer, 1995). In the present study,
the food ration for both live and artificial diet was
reduced (10% of body weight per day during the first
week, 8% per day during second week and 5% per day
during the third and fourth weeks) in the progressive
weeks based on the intensity of feeding.
