Effects of feeding frequency on the growth performance of juvenile starry flounder Platichthys stellatus were investigated.
One thousand fifty fishes were distributed into 15 of 500-L flow-through tanks. Triplicate groups of were
fed experimental diet with five feeding frequency (one meal every two days, one meal a day, two meals a day, three
meals a day and four meals a day) for 9 weeks. Weight gain and specific growth rate (SGR) of fish fed two meals a
day were higher than those of fish fed one meal 2 days and one meal a day, but not different from those of fish fed
three meals a day and four meals a day. Feed consumption of fish fed two meals a day was not different from that of
fish fed three meals a day and four meals a day. Feed efficiency (FE) and protein efficiency ratio (PER) of fish fed
two meals a day were higher than those of fish fed all other diets, except for three meals a day. These results suggest
that the optimal feeding frequency is two meals a day for the optimum growth performance of juvenile starry flounder
under the experimental conditions.
