摘 要：Laboratory-reared Schizothorax davidi larvae and juveniles were examined to assess the formation and characteristics of David’s schizothoracin *** development was observed and their formation period was verifi ed by monitoring larvae and juveniles of *** results revealed that lapilli and sagittae developed before hatching,and the first otolith increment was identified at 2 days post hatching in *** shape of lapilli was relatively stable during development compared with that of sagittae;however,growth of four sagittae and lapilli areas was consistent,but the posterior area grew faster than the anterior area and the ventral surface grew faster than the dorsal ***,the sum length of the radius of the anterior and posterior areas on sagittae and lapilli were linearly and binomially related to total fish length,***,daily deposition rates were validated by monitoring knownage larvae and *** increase in lapilli width was 1.88±0.080 0μm at the ninth increment,which reached a maximum and the decreased gradually toward the otolith edge,whereas that of sagittae increased more *** results illustrate the developmental biology of ***,which will aid in population conservation and fish stock management.
