本文通过对1000尾史氏鲟驯化全人工饲料开口试验,并观察其摄食、生长与形态发育状况。生长曲线表明:不论是体长还体重,50 d龄前增长缓慢,50~100 d龄则以较快速度增长。经100 t饲养,平均体长达28.3 cm,平均体重达69.7g,并获得了的86.7%开口成活率和73.4%的成活率。从而达到提高开食率和成活率的目的,为史氏鲟苗种培育提供切实可行的技术参考。
In this paper, 1000 domesticated Acipenser schrenckii domestication of artificial feed opening test and observe its feeding, growth and morphological development. Growth curves show that both body length and body weight increase slowly before 50 d, and increase rapidly at 50 to 100 d. After 100 t feeding, the average body length was 28.3 cm, the average body weight reached 69.7 g, and 86.7% survival rate and 73.4% survival rate were obtained. So as to achieve the purpose of improving the rate of open feeding and the survival rate and provide practical technical reference for the culture of Amur sturgeon.
