| 摘 要： | 2009年4月15日-5月5日在浙江省舟山水产研究所条石鲷(Oplegnathus fasciatus)人工繁殖期间,逐日选择胚胎和仔鱼样本,连续解剖观察发育后期胚胎和前期仔鱼,光镜观察仔鱼矢耳石和微耳石的形态、日轮数,测定其直径,研究条石鲷的耳石日轮和生长。结果表明,受精后约26h,条石鲷胚胎听囊内出现1对矢耳石和1对微耳石;仔鱼孵出第2天形成第1个轮纹,之后每天形成1轮,孵化后天数(N)和矢耳石日轮数(D)的关系为N=D+1;在第8天左右,矢耳石上出现第2条明显的标记轮,为初次摄食轮。仔鱼耳石长径(rs,μm)与鱼体体长(L,mm)呈线性相关,其关系式为rs=18.146L-44.436;矢耳石长径rs与微耳石长径rl之间存在线性相关,其关系式为rs=0.6125rl+1.9882。根据结果确认,矢耳石轮纹可作为条石鲷仔鱼日龄的判别依据。 |

| Abstract: | Daily-growth increment of otolith and growth of Japanese parrotfish(Oplegnathus fasciatus)were studied and research objects were taken from Zhoushan Fishries Research Institute in April 2009.Microscopic observation was performed on the growth of the otolith during the embryonic development of artificially fertilized eggs and the formation of the first daily growth increment on otolith of larvae.The initial daily growth increment in otolith was formed on the second day after hatching,and continued on a daily... |
