Abstract
The aim of the present study was to determine the suitability of starvation followed by the
realimentation for culture of rohu. Five different feeding schedules were tried by altering the period of
starvation and realimentation of an isonitrogenous and isoenergetic diet. The control group (TCS) was
fed @ 3% of body weight for 90 days trial period and other experimental groups also fed at 3% of BW,
were alternatively starved and fed adopting of cycles of 3 (T1S), 7 (T2S), 15 (T3S) or 25 (T4S) days
during 90 days trial period. Feed was offered to replicates of 10 fingerlings with three replicates per
experimental group, twice at morning and at afternoon. Results indicated that the deprived fish of T1S
and T2S groups showed compensatory growth with hyperphagia, better feed conversion ratio, specific
growth rate and protein efficiency ration. However, the retention of different nutrients was almost
similar among all treatment groups. Fish showed compensatory growth had still lower values of
haemoglobin, haematocrit value, total erythrocytic count, total plasma protein, plasma glucose and,
total plasma lipid and liver glycogen in comparison to control at the end of 90 days trial. These
findings suggested that a cyclic feeding schedule with starvation for 3 to 7 days followed by
realimentation for same period is promising for use in rohu culture as they result in saving of feed cost
without compromising the performance of fish.
