Method for increasing growth rate of Atlantic salmons in circulating water culture system

The invention belongs to the technical field of aquatic animal proliferation and culture, and particularly relates to a method for increasing the growth rate of Atlantic salmons in a circulating water culture system. By regulating the photoperiod in the living environment of female and male Atlantic salmons of different growth and development stages, the gonad development proportion and rate of the Atlantic salmons in the circulating water culture system are lowered, and the growth rate of the Atlantic salmons is increased. The method has the advantages that the rate and proportion of gonad development can be significantly lowered, and the growth rate of the Atlantic salmons is increased. 本发明属于水产动物增养殖技术领域，尤其涉及种提高循环水养殖系统中大西洋鲑生长速率的方法，通过对不同的生长发育阶段的雌、雄大西洋鲑生活环境中的光周期调控来降低循环水养殖系统中大西洋鲑性腺发育比例和速率，提高大西洋鲑生长速率。本发明的优点是可以显著降低性腺发育的速率和比例，提高大西洋鲑的生长速率。
