Abstract
To address the issues of deteriorating water quality,high feed costs,and slow growth in tilapia intensive farming,this study conducted a comparative experiment in pond farming scenarios to systematically explore the impact of Spirulina on the growth performance of Tilapia and its application.Both control and experimental groups were set up in the pond farming,and core indicators such as final average weight,weight gain rate,specific growth rate,and feed conversion ratio were measured.The results showed that the growth performance of Tilapia in the experimental group was superior to that in the control group:in pond farming,the weight gain rate(65.33％)and specific growth rate(0.74％/d)of the experimental group were significantly increased,and the feed conversion ratio(1.28)was significantly lower than that of the control group(1.42).The growth promotion effect of Spirulina is attributed to its nutritional supplementation,ecological regulation,and immune enhancement mechanisms.Although there are currently issues such as high cultivation costs and insufficient standardization of application,these can be gradually resolved through technological optimization.The research indicates that Spirulina has great potential in replacing feed raw materials,constructing ecological farming models,and developing functional products,which can provide important technical support for the green and sustainable development of the Tilapia farming industry.关键词
