Abstract: The biochemical compositions in serum of "allogynogenetic" Qihe crucian carp and its parents were determined using Beckman Model 42 Clinical Biochemical Analyzer,including Total protein (TP),Albumin (Alb),Blood urea nitrogen (BUN),Blood sugar (BS),Lactate dehydrogenase (LDH),Alkaline phosphatase (ALP),Glutamic-oxaloacetic transaminase (GOT) and Hydroxbutyrate dehydrogenase (HbDH).Significance of difference of data were determined by T-test.The results show that there is no significant difference between "allogynogenetic" Qihe crucian carp and its female parent,while there is significant difference between "allogynogenetic" Qihe crucian carp and its male parent.It is demonstrated from the metabolical aspect that the allogenic sperm only makes the stimulation effect,but no biological effect for progeny of gynogenesis.It is concluded that gynogenesis here accords with the traditional concept.
