| 中文摘要: |
| ：采集池养育苗的39日龄之前的梭鱼(Liza haematocheila)仔、稚、幼鱼，对其早期发育阶段体色的变化以及鳍的发生、发育进行了连续观察。结果发现，初孵仔鱼体表不具黑色素，仅卵黄囊具黑色素，孵化后2日龄体表黑色素增加，鳍膜无色透明。8日龄仔鱼开始变得不透明，腹侧有黑色线状斑点。在18-19日龄仔鱼转化为稚鱼时，鱼体背部具大量雪花状黑色素颗粒，在透色光下可观察到淡黄色斑点（黄色素），30日龄的幼鱼与成鱼相似，体表具淡白色，背褐腹白。梭鱼仔鱼在早期发育阶段各鳍的发育顺序是：胸鳍→尾鳍→腹鳍→背鳍→臀鳍→第二鳍棘。初孵仔鱼，鳍褶从头部后缘，向后绕过尾部，终止于卵黄囊后缘，油球外侧。2日龄仔鱼具胸鳍芽，全身由鳍膜包裹，5日龄仔鱼胸鳍和尾鳍鳍膜已具有相当的运动能力，能够起到推动和维持身体平衡的作用。梭鱼鳍在早期发育过程中最明显的变化是尾鳍的生长和鳍节的发育。梭鱼仔鱼在12日龄时出现腹鳍棘芽基， 15日龄时第二背鳍棘出现。17日龄：尾椎骨向上弯曲，尾鳍基本发育完成，长鳍条16根，具10节，中间几根棘条末三节二向分叉，短鳍条上下各6-8根。背鳍有鳍条11根，具5节，最外侧鳍棘具刺，基部有支鳍骨。至30日龄，梭鱼幼鱼各鳍发育完全，与成鱼相似。 |

| The body color variation and fins development at early life stages of mullet(Liza haematocheila) were continually observed by colleting samples of larvae,juveniles and young fish reared in pond from newly hatching to 39 days after hatching. It turn out that the newly hatched larvae fish does not have melanin, just that the yolk sac with melanoma, two days after hatching surface increased melanin, fin membrane colorless and transparent. 8 dph-day-old larvae had become opaque, black line ventral spots. In the 18-19 dph old-age,larvae transformed into juveniles, the fish back with a lot of snow-like melanin granules in the shade under transparent yellowish spots, 30 dph-day-old juvenile similar to adult fish about the surface with a pale white, brown back belly white.The developmental sequence of the fin in the early developmental stages of larval Liza haematocheila is: pectoral fin, caudal, ventral, dorsal, anal, and the second fin spines. Newly hatched larvae, finfold from edge of the head, the tail back to bypass and ends at the rear edge of the yolk sac, lateral oil balls. 2 dph-day-old larvae with a pectoral fin buds, densely fin membrane at all body, 5 dph-day-old larvae had pectoral and caudal fins film.It had considerable athletic ability, and can play a catalytic role in maintaining body balance. During early development of fins the most obvious change is the growth and development of caudal fin sections. Liza haematocheila larvae had appeared pelvic spines bud base at 12 dph days of age, while the second dorsal fin spines appear at 15 dph. 17 dph: tailbone bent upward, basically developed, long fin 16, with 10, the end of the middle section a few spines has two to three bifurcation, short fin root has 6-8 up and down . Dorsal fin with 11 rays, with five outer most spiny fin spines, the base of support fin bones. To 30 dph, young Liza haematocheila’s fins have fully developed, similar to the adult fish. |
