As the scale of Procambarus clarkii culture is gradually mature, it has become the focus of work to accurately detect the biological characteristics of each stage and improve the construction of ecological comprehensive indicators for the growth and development of Procambarus Clarkii. For this purpose, an ecological index evaluation model for growth and development of Procambarus clarkii based on biological characteristics was proposed. According to the evaluation data of ecological indicators of growth and development of crayfish, the data of ecological indicators of growth and development of crayfish were reconstructed with fuzzy correlation constraints, and the process optimization control was used to evaluate the ecological indicators of growth and development of crayfish. The results show that the change trend of the mean value of the ecological index obtained by this evaluation method is consistent with that of the standard value, and the mean value of the reconstructed index reaches the maximum value in the third detection interval, which is 0.85. In the fourth detection interval, the growth tended to be stable and the growth index decreased to 0.37. Each index element conforms to the growth law and the actual situation, so the ecological index evaluation system has high confidence, strong adaptability and accurate evaluation results, which provides a reference for establishing a more accurate and convenient evaluation system.
