养殖密度对华南鲤幼鱼生长特性的影响
|
摘要
为了提高稻田养殖的效率,了解不同养殖密度对华南鲤(Cyprinus carpio rubrofuscus)幼鱼生长特性的影响,本研究在室内水族箱中养殖初始体质量约为0. 35 g、孵化三周的华南鲤幼鱼,密度分别为M1 (43. 48尾/m2)、M2 (86. 96尾/m2)、M3 (173. 91尾/m2)、M4(347. 83尾/m2)四个组,进行11周的养殖试验。试验结果表明,养殖密度对存活率无显著影响,但华南鲤幼鱼的体质量、体长、日增重(DWG)、净增重(NY)、肥满系数、变异系数(CV)和特定生长率(SGR)都随着养殖密度的增加而降低; M1组的体质量、体长、日增重、净增重、特定生长率均最大,其中日增重、净增重、特定生长率均与M2组无显著差异,但是M1组的变异系数较M2组要小。研究结果表明,此阶段华南鲤幼鱼最适养殖密度为M1 (43. 48尾/m2)。
To improve the efficiency of rice paddy and investigate the effects of stocking density on the growth of juvenile Cyprinus carpio rubrofuscus,the growth traits of the carps stocked in different densities were measured and analyzed. The three-week-old juveniles with initial average body weight of 0. 35 g were stocked and reared for eleven weeks in indoor aquarium with different stocking densities of 43. 48,86. 96,173. 91,and 347. 83 individuals/m~2,which were marked as M1,M2,M3 and M4,respectively. The results showed that stocking density had no significant effect on the survival rate. But,the body weight,length,daily weight gain(DWG),net yield(NY),condition factor(CF),coefficient of variation(CV) and specific growth rate(SGR) were decreased with the increasing of stocking density. The body weight,length,DWG,NY and SGR of M1 group were the highest. Furthermore,CV of M1 group was lower than that of M2 group. The result indicated that the optimal stocking density of juvenile Cyprinus carpio rubrofuscus in this growth period was M1(43. 48 individuals/m~2).
