چکیده
 To investigate the ontogeny of Perccottus glenii, embryonic, larval and juvenile development of P. glenii were examined under captive
condition. The fertilized eggs with numerous oil droplets were orange-pink in
color, prolate spherical in shape and had average length of 3.32±0.14 mm and width of 1.24±0.04 mm. From fertilization to hatching,
the ontogenesis of the fish spent more than 200 h, and the process of embryonic
development was divided into 25 stages based on the morphological
characteristics. The newly hatched larvae, with well-developed swim bladder and
pectoral fins, measured 5.07±0.18mm
in total length. Initial feeding occurred at day 2 after hatching (AH) and the
complete absorption of yolk sphere was observed 3 days after hatching. At day
40 AH, scales and vertical pigment were found to be appear. Scales covered the
entire body and all fins were well developed 70 days AH, at which time the
juveniles reached the young stage with a total length (TL) of 24.74±4.28 mm. At day 140 AH, The fry with a TL
of 29.57±4.65 mm, were
morphologically similar to the adults except for size.
