摘　　要：研究报导了若干环境因子对揭菖鲉仔鱼生活、生长与生存的影响。初步得出褐菖鲉集群、有一定的弱趋光性，空间分布受昼夜变化影响，最适温度为10－14℃、盐度为14－22、pH范围为8－9，培育以弱光（30～1500lx）较为适宜。适宜的仔鱼培育密度为40尾／1000mL左右。The study was conducted to reveal the effect of Several environmental factors on the living, growing and survival of Sebasticus marmoratus larvae. The preliminary results show that the larvae like gentle flow,schooling and weak light, that its distribution varies with the day or right, and that its optimal survival conditions are as follows, such as the temperature 10℃~ 14℃, the salinity 14 ~ 22, the pH 8 ~ 9, the light 3 00~ 0500 lx and the culture density about 40/ 1000 ml
