摘要
研究了鬼人工催产、受精卵孵化、饵料系列的选择以及仔、稚、幼鱼的生态习性,并对其胚胎发育进行了连续观察。使用激素LRH A3和HCG的人工催产、人为条件下的受精卵孵化和仔、稚、幼鱼培育,经35d的人工育苗共获得了平均全长2.1cm左右的鬼幼鱼11.025万尾,受精卵平均孵化率为62.9%,育苗平均成活率达30.2%。结果表明提高海水盐度能提高鬼受精卵的孵化率,轮虫、卤虫、桡足类是鬼仔、稚、幼鱼的优质饵料,仔、稚、幼鱼有两个死亡高峰期,水质好坏是影响育苗成活率高低的主要因素。
The author studied the artificial inducement for spawning,the hatching of fertilized egg, the bait series selection, the zoology temperament of larva fish,juvenile and young fish of Inimicus japonicus,also conducted the consecutive observation of the embryo growth of Inimicus japonicu. The research for artificial breeding acquired (110.25) thousand young Inimicus japonicus after 35 days, the average hatching rates of fertilized egg was (62.9%),the average survival rate of breeding was 30.2%, by artificial hastening in using the hormone LRH-A and HCG,hatching of fertilized egg in artificial and breeding to the young fish.The result shows the hatching rate of Inimicus japonicus fertilized eggs will increase with the increasing of the seawater salinity; rotifer,artemia and copepodid are high quality bait series; larva fish,juvenile and young fish have two death peak periods, and quality of water is a main factor influencing the survive rates of breeding.
