Abstract
The effect of dietary moisture and volume on specific dynamic action (SDA) was investigated in the southern catfish Silurus meridionalis Chen at 27.5°C by filling the formulated diet, water and cellulose in a section of grass carp intestine (0.25 g). The results showed that there were no significant differences in any SDA variables among fish fed diets with different moisture (p>0.05). Duration, energy expended on SDA and SDA coefficient for fish fed with the cellulose diet (1 g cellulose filled in 0.25 g intestine) were significantly higher than those of the control group (0.25 g intestine) (p< 0.05). Duration, energy expended on SDA and peak metabolic rate of fish fed with intestine diet (1 g intestine filled in 0.25 g intestine) was much higher than those of cellulose group. The results of this study suggest dietary moisture has little effect on SDA response and dietary cellulose induce extra mechanical SDA energy cost.
