摘　　要：为了实现绿色养殖和精细化健康养殖,提高养殖效率和经济效益,设计了基于克氏原螯虾生长模型的饲料精准投喂模型。利用灰色关联度分析法筛选出对克氏原螯虾生长发育影响最大的环境因子,再从线性和指数两个角度对克氏原螯虾生长模型进行优化拟合;基于传感器实时采集的水温、pH值、溶解氧等环境参数,利用RBF神经网络对精准投饵预测模型进行训练,得出最佳综合环境影响因子数值;根据不同水温和pH条件下克氏原螯虾的死亡率,以及其他已知养殖条件,即可根据克氏原螯虾精准投饵预测模型计算精确投喂量,从而提高养殖的经济收益。In order to achieve green and refined healthy farming,enhance farming efficiency and economic benefits,a feed preci⁃sion feeding model was designed based on the growth model of Procambarus clarkii.The environmental factors that have the great⁃est influence on the growth and development of Procambarus clarkii were screened out by grey relational analysis,and then the growth model of Procambarus clarkii was optimized and fitted from both linear and exponential angles.Based on the environmen⁃tal parameters such as water temperature,pH value and dissolved oxygen collected by sensors in real time,RBF neural network is used to train the precise feeding prediction model,and the best comprehensive environmental impact factor value is obtained.Based on the mortality rate of Procambarus clarkii under different water temperature and pH conditions,as well as other known aquaculture conditions,the precise feeding amount can be calculated using a precise feeding prediction model for Procambarus clarkii,thereby improving the economic benefits of aquaculture.
