皱纹盘鲍的个体能量收支

An energy budget for individual pacific abalone ( Haliotis discus hannai Ino).

对皱纹盘鲍的呼吸、摄食、生长及能量收支等实验研究表明，鲍的耗氧率与壳长、体重、温度及昼夜变化有关，耗氧率与壳长、体重均呈幂函数关系，一天中１６～４时（夜间）耗氧率高于４～１６时（白天）且在１８～２０时达峰值．同温度下鲍日摄食率与体重呈幂指数关系，日（相对）摄食率随温度升高而增加，而日相对摄食率、日相对生长率均随壳长、体重增加呈下降趋势．鲍在１４～２０℃内对海带的总转化效率为５３％．鲍软体部、海带及鲍粪便干品的比能值分别为１９．２、８．５７和７．２３ｋＪ·ｇ－１．１４～２０℃皱纹盘鲍摄入能量的３４．６～４８．６％为粪能，２２．０～３８．２％的能量用于自身代谢，５．６～２８．２％用于贝体软体部的生长．

Experimental studies on the respiration, feeding, growth and energy budget of pacific abalone ( Haliotis discus hannai Ino) indicate that its oxygen consumption rate was correlated with shell length ,body weight, temperature and alternate change of day and night. The relationships of oxygen consumption rate with shell length and body weight were all power function. The oxygen consumption between 16 o'clock and 4 o'clock (night time) was higher than 4 o'clock to 16 o'clock(day time), with a peak at 18～20 o'clock. At same temperature, the daily feeding rate of abalone and its body weight showed a relationship of power function. The daily relative feeding rate was increased with temperature. The rates of daily relative feeding and growth were decreased with increasing shell length and body weight. The total conversing efficiency of abalone on kelp ( Laminaria japonica ) was 53.0% at 14～20℃. The energy contents of abalone flesh,kelp and abalone's dry feces were 19.2, 8.57 and 7.23kJ·g -1 , respectively. At 14～20℃, among the assimilation energy by abalone, the feces accounted for 34.6～ 48.6 %,the metabolism by abalone self about 22.0～38.2%, and about 5.6～28.2% was used to accumulation for the flesh of body.
