ENERGY BUDGETS OF HALIOTIS DIVERSCICOLOR AQUATILIS FED BY GRACILARIACEAE LICHENIODES AND FORMULA FEED

The energy budgets of Haliotis diverscicolor aquatilis fed by Gracilariaceae licheniodes and formula feed were studied in this paper. There was no significantly different diurnal oxygen consumption rate of H. diversicolor aquatilis between the two groups (P0.05). The absorption efficiency of the two feeds groups was not significantly different (P0.05), while the feed coefficient,protein efficiency ratio,gross growth efficiency were significantly different (P0.05). Although the excretion energy of the formula feed group was significantly higher than that of G. licheniodes group (P0.05), the metabolic energy and mucus energy of the formula feed were significantly lower than those of G. licheniodes group (P0.05). The feces energy and the shell growth energy of the two groups were not significantly different (P0.05). The shell growth energy was so low that it can be neglected. So the somatic part growth energy of the formula feed was significantly higher than that of G. licheniodes group (P0.05). The energy equations of H. diverscicolor aquatilis fed by G. licheniodes (the former) and formula feed (the latter) were: 100C=(12.76±1.22)F+(76.47±5.33)R+(2.74±0.40)U+(6.75±0.46)M+(2.78±0.48) P g+(0.03± 0.01) P sh-(1.53±4.19) 100C=(12.15±1.69)F+(54.94±5.10)R+(4.50±0.70)U+(3.99±0.07)M+(29.79±4.77)P g+(0.03± 0.01) P sh-(5.40±7.43)
