在我国北方进行真鲷全人工养殖，至少要经过一个越冬期方可达到商品规格。真鲷在低温条件下，生长缓慢，延长了养殖周期，增加了技术难度，提高了生产成本，极大地阻碍了我国北方沿海真鲷养殖业的发展。本研究的目的是为了探讨在低温条件下促生长剂对真鲷的促生长效果。１材料 In the northern part of China, all the artificial breeding of sea bream, at least through a winter period before they can reach product specifications. At low temperature, the red sea bream grows slowly and prolongs the breeding cycle, increasing the technical difficulty and increasing the production cost, which greatly hinders the development of the sea bream aquaculture in the northern coast of China. The purpose of this study was to investigate the effect of growth promoters on the growth of red sea bream at low temperatures. 1 material
