| 摘 要： | 研究了两品系蒙古裸腹溞(晋南品系和内蒙品系)继饥饿后的补偿生长及其生长发育的适宜食物密度。结果表明,两品系蒙古裸腹溞生长发育的最适食物——篕∏蛟迕芏染?50×104/mL。对两品系蒙古裸腹溞而言,饥饿0.5d的蒙古裸腹溞有全补偿生长,饥饿1~2d有部分补偿生长现象,饥饿超过3d已没有补偿生长。可以认为,蒙古裸腹溞仅在短时间饥饿时有补偿生长现象的发生。

| Abstract: | Two experiments were conducted in order to determine the optimum food density of Moina mongolica and to clarify M. mongolica have or not the phenomenon of compensatory growth. The test animals were two strains of Moina mongolica(Jinnan strain and Neimeng strain) in this study. Jinan strain of M. mongolica was collected from Lake Xiaochi in south of Shanxi Province in 1982; Neimeng strain of M. mongolica was collected from Lake Zhagesitai in Inner Mongolia in 2002. Laboratory-reared M. mongolica juveniles( a... |
