| 摘 要： | 从舟山群岛采集体长7.1～18.7 cm、体重3.2～55.6 g的野生泥鳅样本,依据侧线鳞数目初步分出127尾大鳞副泥鳅(Paramisguruns dubryanus)和136尾真泥鳅(Misguruns anguilliaudatuses)。按体长段分组,分别记录两种泥鳅体长、体高、尾柄长、尾柄高、头长、吻长、口须长、头长等数据,统计分析体长/体高、尾柄长/尾柄高、头长/吻长、口须长/头长几组数据,结果显示:大鳞副泥鳅尾柄长为尾柄高的(1.07±0.10)倍,真泥鳅尾柄长是尾柄高的(1.84±0.12)倍。大鳞副泥鳅和真泥鳅口须长/头长分别为1.05±0.11,0.54±0.11。尾柄长/尾柄高口须长/头长在两种泥鳅之间也有显著的差异。

| Abstract: | Loach samples with the body length of 7.1~18.7 cm and body weight of 3.2~55.6g were collected in Zhoushan Islands.According to the lateral-line of loach,127 Paramisguruns dubryanus and 136 Misguruns anguilliaudatuses were distinguished.After grouping the loaches by body length,the body length(BL),body height(BH),length of caudal peduncle(CPL),head length(HL),snout length(SL),length of mouth beard(MBL),head length(HL) were recorded.The data of BL/BH,CPL/CPH,HL/SL,MBL/HL were analyzed.The results showed that CPL of P.dabryanus was 1.07±0.10 times more than CPH and CPL of M.anguillicaudatus was 1.84±0.12 times more than the CPH;MBL/HL of P.dabryanus and M.anguillicaudatus was 1.05±0.11 and 0.54±0.11,CPL and MBL/HL the two loaches were significantly different. |
