| Abstract: | Objective] The aim was to study the basic biological data of Hemibarbus maculatus Bleeker in Yuanhe River.Method] Using H.maculatus as research objects,exterior morphological characteristics of 140 H.maculates in Yuanhe River were measured.Result] The totol length of H.maculates was 1.21±0.023 6 times as long as body length.The body length was 4.78±1.496 5 times as long as body height,3.76±0.203 5 times as long as head length,6.68±1.032 4 times as long as caudal peduncle length.The head length was 2.80±0.302 1 times as long as snout length,4.01±0.393 9 times as long as eye diameter,3.21±1.151 5 times as long as interorbital width,2.10±0.307 5 times as long as head width,1.81±0.148 4 times as long as head height and 4.44±0.649 9 times as long as mouth breadth.The caudal peduncle length was 1.68±0.2866 times as long as caudal peduncle height.The correlation equation between body weight and body length was W=0.022 4L2.916 8(r2= 0.957 6).Coefficient of fatness(K) was 1.57±0.190 8.The net weight to body weight(V) was 0.87±0.057 2.Coefficient of intestine(Ci) was 1.08±0.126 1.The body length and intestines length showed a linear relation and its correlation equation was Y = 1.262 4X-2.810 9(r2=0.793 4).Except harslet weight,gland weight and gonadsomatic index,other morphological characteristics of H.maculates has no significant difference between female H.maculates and male H.maculates(P>0.05).Conclusion] H.maculates in Yuanhe River showed a negative allometric growth. |
