于1989年10月—1990年6月间,进行了氦氖激光散焦扩束辐照对孔雀鱼抗病力及生长发育影响的试验。结果表明,经能量密度为2.86J/cm~2激光处理的仔鱼,在车轮虫和水霉、绵霉等病原体侵袭下,其成活率比对照组高126％。在能量密度为5.37J/cm~2激光辐照下,两个月的幼鱼,其α-淀粉酶和β-淀粉酶活性分别比对照组的高36.4％和52.5％;蛋白酶活性无明显变化;脂肪酶活性降低53.5％。在生长方面,90天雄(雌)鱼的体长比对照组增加8.3％(9.7％),体重增加41.7％(39.6％);当激光的辐照剂量为7.52J/cm~2时,其对机体生长发育所产生的生物刺激作用并没有随着相应增强。
From October 1989 to June 1990, the effects of He-Ne laser defocusing and expanding beam irradiation on the disease resistance and growth of guppies were tested. The results showed that the survival rate of larvae larvae with energy density of 2.86J / cm ~ 2 was 126% higher than that of the control group under the attack of pathogen such as rotifers, water molds and mildew. At the energy density of 5.37J / cm ~ 2, the α-amylase and β-amylase activities of juveniles of two months were 36.4% and 52.5% higher than those of the control group respectively, while the activity of protease did not change significantly ; Lipase activity decreased by 53.5%. In terms of growth, the body length of 90-day-old male and female fish increased by 8.3% (9.7%) and 41.7% (39.6%) of that of the control group. When the laser irradiation dose was 7.52J / cm ~ 2 The biological stimulation of growth and development of the body does not increase with the corresponding.
