| 摘 要： | 针对饥饿对大菱鲆雌核发育二倍体仔鱼前期生长发育的影响进行研究,并对仔鱼的饥饿不可逆点进行了测定。结果表明,水温14.5—16℃的培育条件下,大菱鲆雌核发育饥饿仔鱼卵黄于5—6日龄消耗殆尽,油球6—7日龄消耗殆尽;饥饿仔鱼最高初次摄食率出现在4日龄,为85.3%;仔鱼的饥饿不可逆点出现在8日龄;饥饿仔鱼全长生长速度显著慢于投喂仔鱼,6日龄后全长呈负增长,并且出现胸角突出、体色暗黑、消化道萎缩等较为明显的饥饿特征。本实验同时对大菱鲆常规二倍体仔鱼的饥饿耐受情况对照研究,表明,常规二倍体饥饿仔鱼的卵黄和油球消耗规律、初次摄食率变化、PNR点及全长生长与雌核发育仔鱼无显著差异。

| Abstract: | Starvation is a major reason causing mortality during early feeding stage of fish larvae. We conducted an experiment to study how the larvae endure starvation via absorption, transition, and disappearance of inner nutrition materials, yolk, and oil globule. The diploidy gynogenesis of larvae are different from normal ones in insemination and germ plasm. We studied the effects of starvation on the growth and development of gynogenesis of turbot larvae by detecting the absorption of yolk and oil globule, the ... |
