摘要
为探究葡萄糖和维生素C(VC)对普安银鲫(Carassius auratus gibelio)早期发育的影响,采用静水溶液浸泡法研究了葡萄糖和VC溶液浸泡中普安银鲫仔鱼出膜时间、孵化率、成活率及卵黄囊仔鱼生长特点。结果显示,葡萄糖溶液质量浓度低于15 g·L-1,仔鱼出膜时间随着葡萄糖质量浓度的增加而缩短,孵化率、成活率、体质量和全长则升高;葡萄糖溶液质量浓度高于15 g·L-1对普安银鲫的早期发育表现出抑制作用。VC溶液质量浓度低于30 mg·L-1时,仔鱼出膜时间随着ρ(VC)的增加而降低,孵化率、成活率、体质量和全长则升高。ρ(VC)高于30 mg·L-1对普安银鲫的早期发育表现出抑制作用。研究表明适宜浓度的葡萄糖和VC能促进普安银鲫的早期发育。
To study the effects of glucose and vitamin C（ VC） on early development of Puan silve crucian carp（ Carassius auratus gibelio）,we studied the membrane time,hatching ratio,survival rate and growth characteristics of C. auratus gibelio socked in glucose and VCsolutions by static aqueous solution immersion. The results show that when the concentration of glucose was below 15 g·L^-1 and concentration of VCwas below 30mg·L^-1,the membrane time of larvae was decreasing and the hatching ratio,survival rate,weight and full-length were increasing with the increase of concentrations glucose and VC. Concentration of glucose solution higher than15 g·L^-1 and concentration of VCsolution higher than 30mg·L^-1 had inhibitory effect on early development of C. auratus gibelio. The research indicates that appropriate concentrations of glucose and VCcan promote early development of C. auratus gibelio.
