Abstract
Clarias batrachus fingerlings were maintained under
laboratory conditions and fed on a 40% soybean
based protein diet on a circadian pattern selecting
six different time intervals, viz., 0800h, 1200h, 1600h,
2000h, 2400h and 0400h. The results indicated that
body weight gain (live weight gain and specific
growth rate) in C. batrachus on a time restricted meal
is optimal when the food is made available at midnight
viz., 2400h. Better accumulation of protein with
less excretion of ammonia in fish body was also
reported at this time of feeding. The study
concluded that the growth rates of fish fed during
night time (mid-night) had significantly low food
conversion ratios and food wastage. Therefore, it is
beneficial to feed C. batrachus at mid-night
