| 摘 要： | 本文主要从光照、盐度、温度和溶解氧四个方面简述了环境因子对鱼类胚胎及幼鱼、成鱼的影响，旨在为鱼类的健康养殖提供依据。光照通过光照强度及光周期变化对鱼类胚胎发育及幼鱼、成鱼生长产生影响，且因种而异；盐度在一定范围内不影响鱼类生长发育，但超出适宜盐度后，会对鱼类生长发育产生影响；温度主要对鱼类代谢反应速率起控制作用，影响其生理生化进程，从而成为影响鱼类生长和发育的重要环境变量；溶解氧在一定适宜范围内不影响鱼类生长发育，但不在适宜范围内（偏高或偏低）则会影响鱼类正常的胚胎发育及生长。

| Abstract: | In present study,the effects of light,salinity,temperature and dissolved oxygen on growth and development of fish are summarized,which provided support for aquaculture.Light has influence on fish embryonic development and growth by the changes of light intensity and photoperiod,and differs in species.Salinity does not affect fish development and growth in a certain range,unless it is beyond the suitable range.Temperature affects fish growth and development by influencing fish metabolism rate,physiological and biochemical process.Dissolved oxygen does not affect the fish development and growth in a suitable range,unless it is beyond the suitable range. |
