摘要
采集管角螺的粪便,烘干处理后测定其营养成分组成;并在实验室条件下,研究了管角螺(Hemifusus tuba)代谢物对湛江等鞭金藻(Isochrysis zhanjiangensis)、牟氏角毛藻(Chaetoceros muelleri)和亚心型扁藻(Platymonas subcordiformis)生长的影响。结果表明:管角螺粪便中含有粗蛋白质(9.8%)、磷(0.38%)等微藻生长所需的营养物质;管角螺的代谢物对三种单胞藻的生长有明显的促进作用(P<0.05),三种微藻的生长与代谢物的添加量呈正比相关;管角螺代谢物对不同微藻的生长作用随种类的不同而具有明显的差异,对湛江等鞭金藻和牟氏角毛藻的增殖作用明显高于亚心型扁藻(P<0.05)。
Collection the dung of Hemifusus tuba, after drying treatment and measure its nutritional ingredients. And under laboratory conditions,the influence of growth to Isochrysis zhanjiangensis ,Chaetoceros mueUeri and Platymonas subcordiformis of Hemifusus tuba metabolites were studied. The results showed that the waste of Hemifusus tuba contains coarse protein （9.8%）, p （0.38%）, and other nutrients needed for the growth of microalgae;the metabolites of Hemifusus tuba could obviously promote the growth of Isochrysis zhanjiangensis ,Chaetoceros muelleri and Platymonas subcordiformis （P〈0.05）. Their growth with the adding amount of the rnetabolites were positively related; and the effect metabolites to growth of different microalgae had obvious differences,according to the different types of lsochrysis zhanjiangensis and Chaetoceros muelleri proliferation effect was significantly higher than the Platymonas subcordiformis （P〈0.05）.
