摘　　要：将荷包红鲤、彭泽鲫和萍乡红鲫放入锅中煮沸,取出肌间骨各部位,比较分析肌间骨数目、形态、类型和分布规律。结果显示:荷包红鲤的肌间骨数目为70~99(x=88)根,彭泽鲫肌间骨数目为78~92(x=85)根,萍乡红鲫的肌间骨数目为62~89(x=77)根;荷包红鲤和彭泽鲫肌间骨数目不存在显著性差异,荷包红鲤和萍乡红鲫肌间骨数目存在显著性差异(P<0.01),彭泽鲫和萍乡红鲫肌间骨数目也存在显著性差异(P<0.01);3种鱼肌间骨均存在髓弓小骨和脉弓小骨,但未见椎体小骨。肌间骨的类型均为简单型(“I”型、“卜”型、“Y”型)、中间型(一端多叉型、两端两叉型)和复杂型(两端多叉型、树枝型),简单型数目最多;3种鱼身体两侧的肌间骨数量不完全一致,不同部位肌间骨类型分布存在差异,左右两侧的肌间骨分布不同,但无显著差异。试验结果可为进一步研究其肌间骨时空发育规律,培育少或无肌间骨的鲤、鲫新品系提供基础资料。Red common carp Cyprinus carpio var.wuyuanensis,crucian carp Carassius auratus var.pengsenensis and C.auratus var.pingxiangnensis were put into a pot and boiled,then the intermuscular bones were removed,and the number,morphology,type and distribution of the intermuscular bones were compared and analyzed by conventional measurement and anatomical methods.The results showed that there were intermuscular bones ranging from 70 to 99 in red common carp,with an average of 88,ranging from 78 to 92 in crucian carp,with an average of 85,and ranging from 62 to 89 in C.auratus var.pingxiangnensis,with an average of 77,without significant difference in the numbers of intermuscular bone between red common carp and crucian carp,and with significant differences in the numbers of intermuscular bone between red common carp and C.auratus var.pingxiangnensis(P<0.01).There were epineuria bones and epipleural bones in intermuscular bones among all the three fish varieties,without epicentraliabones.The simple type(″I″type,″卜″type,″Y″type),middle type(one end multi-fork,two ends two-fork)and complex type(two ends multi-fork,and twig-shaped type)were found in intermuscular bones,with the most simple types.The numbers of intermuscular bones on both sides of the body were not completely consistent,and the distribution of intermuscular bone types was different in different positions among the three fish warieties,and the distribution of intermuscular bones was different on the left and right sides,without significant difference.The findings provide basic data with further research on the spatiotemporal development of intermuscular bone and breeding new strains of cyprinids with little or no intermuscular bone.
