中文摘要:
      研究超声波辐射频率分别为0、20、28、40kHz时,对质量为(0.23±0.05)g彩虹鲷幼鱼生长发育的影响. 30d的试验结果表明:超声波辐射频率为20kHz试验组的质量相对增加率、特定生长率、蛋白质表观消化率最高,分别为(108.80±4.09)%、(2.45±0.70)%·d-1和(90.60±1.26)%;辐射频率为28kHz试验组彩虹鲷幼鱼的干物质消化率最高,为(69.58±1.94)%;超声波辐射频率为40kHz试验组的质量相对增加率、特定生长率、干物质消化率、蛋白质表观消化率最低,分别为(71.79±1.64)%、(1.80±0.31)%、(60.46±1.17)%和(86.06±1.81)%. 由研究结果可知,不同超声波辐射频率对彩虹鲷幼鱼的质量相对增加率、特定生长率、消化率有显著影响(P<0.05). 超声波辐射频率在20~28kHz间有利于彩虹鲷幼鱼生长,超声波辐射频率为40kHz时不利于彩虹鲷幼鱼生长发育.
英文摘要:
      The effects of variable frequency ultrasonic on the growth and development of Red Tilapia larvae have been studied. The Red Tilapia larvae(body weight was (0.23±0.05)g) that were reared for 30 d was divided into four ultrasonic frequency 0,20,28,40kHz. The results indicated that in frequency 20 kHz,the Red Tilapia larvae had the highest relative weight gain rate was (108.80±4.09)%,specific growth rate was (2.45±0.70)%·d-1 and the apparent digestibility of protein matter was (90.60±1.26)%. In frequency 28kHz,the Red Tilapia larvae attained the highest apparent digestibility of dry matter was (69.58±1.94)%. However,in frequency 40kHz,the relative weight gain rate was (71.79±1.64)%,specific growth rate was (1.80±0.31)%,the apparent digestibility of dry matter was (60.46±1.17)% and protein matter was (86.06±1.81)% were the minimum. The study results show that different frequency ultrasonic had significant effects on the weight gain rate,specific growth rate,digestibility of Red Tilapia larvae(P<0.05). It is advantageous to the growth of the Red Tilapia larvae with the ultrasonic frequency between 20 to 28 kHz,but it is adverse in 40kHz.
