摘要/Abstract

摘要： 研究了光照强度(0、1000、2000和3000 lx)对两种养殖方式(添加复方中草药制剂饲料和泼洒微生物制剂)下刺参幼参生长和消化酶活性的影响.结果表明：光照强度对刺参幼参的相对体质量增长率(WGR)和特定生长率(SGR)影响显著(P<0.05),其趋势为2000 lx ＞ 1000 lx ＞ 3000 lx ＞ 0 lx；相同光照强度下，复方中草药组刺参幼参WGR和SGR均显著高于微生物制剂组.光照强度对刺参幼参消化酶活性也有显著影响，淀粉酶和脂肪酶活性均为2000 lx ＞ 1000 lx ＞ 3000 lx ＞ 0 lx，蛋白酶活性为1000 lx ＞ 2000 lx ＞ 0 lx ＞ 3000 lx; 相同光照强度下，两种酶活性多为复方中草药组高于微生物制剂组.

Abstract: The effects of light intensity(0, 1000, 2000 and 3000 lx) on the growth and digestive enzyme activity of juvenile sea cucumber Apostichopus japonicus under two kinds of culture methods (compound Chinese medicine preparation and microbial preparation) were studied. Results showed that the relative mass gain rate (WGR) and the specific growth rate (SGR) of juvenile sea cucumber were significantly affected by light intensity (P<0.05), and the orders of WGR and SGR (form high to low) of juvenile sea cucumber under different light intensities were 2000 lx > 1000 lx > 3000 lx > 0 lx. Under the same light intensity, the growth of juvenile sea cucumber under the two kinds of culture methods were significantly different (P<0.05), with the WGR and SGR of the Chinese medicine treatment being greater than those of the microbial treatment. The light intensity also significantly affected the digestive enzyme activity of juvenile sea cucumber. The order of amylase and lipase activity was 2000 lx > 1000 lx > 3000 lx > 0 lx, while that of protease activity was 1000 lx > 2000 lx > 0 lx > 3000 lx. Under the same light intensity, the digestive enzyme activities of the Chinese medicine treatment were generally higher than those of the microbial treatment.
