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,其他季节慢,最适宜生长水温范围为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1900 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: Abstract: Fugu flavidus grows in early-stage faster than in late-stage in the culture ponds. It grows the faster in autumn than 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 it grows in approximate equal speed. Illumination intensity of feeding peak is about 1900lux, 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 like clustering for food, which is convenient for feeding in fixed time and site.
