褐牙鲆幼鱼 (体重 0 .71～ 4 .16 g;体长 4 .4 5～ 8.14cm)在 2 4℃下保持 5个摄食水平 (0～最大 )。投喂人工配合饵料。褐牙鲆能量和干物质的吸收效率随摄食水平的增加而增加 ,平均为97.38%和 76 .73%。褐牙鲆排粪能 (F )占摄食能的比例为 0 .95 %～ 2 .83% ,随摄食水平的增加而减少 ;氮排泄 (U)占摄食能比例为 5 .5 2 %～ 6 .77% ,各摄食水平下变化不大 ;标准代谢耗能 (Rs)占摄食能比例为 1.0 5 %～ 7.82 % ,随摄食水平的增加而减少 ;在各摄食水平条件下 ,摄食代谢耗能(Rf)占摄食能比例变化不大 ,平均为 4 5 .72 % ;生长能 (G)占摄食能比例为 32 .6 7%～ 4 9.2 1%。随摄食水平增加而增加。在最大摄食水平时 ,褐牙鲆能量分配形式为 :10 0 C =0 .95 F + 5 .5 2 U +4 4.31R+ 4 9.2 1G
Juvenile flounder juveniles (body weight 0.71 to 4.16 g; body length 4.55 to 8.14 cm) maintained 5 feeding levels (0 to maximum) at 24 ° C. Feeding artificial with bait. The energy efficiency and dry matter absorption efficiency of Avicennia marina increased with the increase of feeding level, with an average of 97.38% and 76.73%. The ratio of fecal excrement (F) to feeding energy of the Japanese flounder (Paralichthys olivaceus) was between 0.95% and 2.83%, which decreased with the increase of feeding level. The ratio of nitrogen excretion (U) to food intake was 5.52% -6 .77%, and no significant change was found under each feeding level. The standard metabolic energy expenditure (Rs) accounted for 1.05% -7.82% of the total food intake, which decreased with the increase of feeding level. At each feeding level, (Rf) accounted for a small change in food intake, an average of 45.72%; growth (G) to feed ratio of 32.67% ~ 4 9.2 1%. Increases with increased food intake. At the maximum feeding level, the energy allocation pattern of the flounder was: 10 0 C = 0 .95 F +5 .5 2 U +4 4.31R + 4 9.2 1G
