| 摘 要： | 在海水土池养殖条件下,菊黄东方鲀养殖早期生长速度比后期快,从季节上看,秋季生长最快,其他季节较慢,最适生长水温范围为23～29℃。体长与体重关系的幂函数方程W=0.05017L2.7866,R2=0.9739,生长近似等速生长。摄食高峰时的光照强度在1 900 lux左右,属于偏晨昏的白昼型鱼类。摄食响应时间短,摄食方式呈从底层向表层急冲吞食膨化饵料,有集群索饵特点,适宜定时定点进行投饵。

| Abstract: | Being cultured in the seawater pond,Fugu flavidus grows faster in early-stage than in late-stage and it grows faster in autumn than in the other seasons.The optimum water temperature for growth is 23~29℃.The equation of power function between body length and body weight is W=0.05017L2.7866,R2=0.9739,which shows that it grows in approximate equal speed.Illumination intensity of feeding peak is about 1 900 lux,and it belongs to daytime fish closed to dawning and dusk.Fugu flavidus eats artificial feed very quickly from bottom to surface in short-time response and likes clustering for food,which is convenient for feeding in fixed time and site. |
