The application provides a method for constructing an intelligent prediction model for the quality of frozen prawns based on a random forest algorithm. The method combines test data of ultrasonic-assisted immersion frozen prawns, ice crystal morphology detection data, and quality index detection data, and establishes a multivariate characteristic quality prediction model based on the random forest algorithm between the ultrasonic-assisted immersion frozen process parameters, the ice crystal morphology parameters, and the quality evaluation indexes, so as to realize accurate and efficient prediction of the frozen quality indexes. In combination with SHAP explanation and analysis, the influence weight and the nonlinear response characteristics of each parameter in the prediction model on the quality indexes are quantified, the interactive influence of each parameter characteristic on the quality is analyzed, the internal mechanism that the ultrasonic parameters control the ice crystal morphology and then affect the quality is revealed, and a clear target is provided for process optimization.

The utility model discloses a biomimetic nest for macrobrachium culture, and relates to the technical field of macrobrachium culture, the biomimetic nest for macrobrachium culture comprises an elastic bandage, a plurality of biomimetic modules are arranged inside the elastic bandage, and the biomimetic modules are bound and fixed through the elastic bandage. The bionic module comprises a fixing assembly and pipe bodies, one fixing assembly corresponds to four pipe bodies, the four pipe bodies are located on the periphery of the fixing assembly, the fixing assembly comprises a center base, connecting arms are arranged on the peripheral surface of the center base, fixing frames are arranged at one ends of the connecting arms in a hot melting mode, and the fixing frames are connected with the fixing assemblies in a hot melting mode. By means of the scheme, the problems that when existing macrobrachium rosenbergii is bred, due to the fact that the macrobrachium rosenbergii is prone to being stacked together, the macrobrachium rosenbergii fight with one another, the macrobrachium rosenbergii eats silkworm after shelling, the death rate is high, and the breeding effect is poor are solved.
