摘要
连续观察人工育苗中同一批受精卵,在水温23.2～23.4、盐度27.00～27.80‰条件下,经过3h36min孵出仔鱼,并继续观察仔、稚鱼发育过程中的形态特征与生态习性。还比较了不同年份与不同批次的观察资料,讨论了水温等环境条件变化对胚胎发育的影响,以及仔、稚鱼器官发育与日龄、生长速度等关系。
Continuons observation of the same batch of the zygote of Pseudosciaena crocea(Richardson)under the conditon of artificial seed-breeding showed that the zygote were batched out in 3h36mm in the state of 23. 2-23. 4℃ of water temperature and 27. 00-27. 80‰ of salinity .and its morphological characteristics and its ecological habits were continuing observed in the process of the larval, juuenile fish development. In the paper,also the datas of different years and different batches were compared .and effcts of varying of envi-roment conditions such as water temperature on the embryonic development of the larval,juvenile fish.and the relations between the organ development and the daily age and the growth speed and etc. ,were discussed.
