Method and device for detecting feeding state of fishes

The invention relates to the technical field of aquaculture, in particular to a method for detecting the feeding state of fishes. The detection method comprises the following steps: acquiring texturalfeatures and shape features of fish schools during ingestion; and substituting the textural features and the shape features of the fish shoal during ingestion into a preset depth forest model to obtain the ingestion state of the fish shoal to be detected. According to the method, the texture features and the shape features of the fish schools during ingestion and the corresponding ingestion states are combined to construct the deep forest model, so that the ingestion states of the fish schools can be judged directly through the texture features and the shape features of the ingestion picturesof the fish schools, the accuracy is high and can reach about 95%, and theoretical support and solution are provided for accurate feeding of fishes. 本发明水产养殖技术领域，尤其涉及一种鱼类摄食状态的检测方法。所述检测方法包括：获得鱼群采食时的纹理特征和形状特征；将所述鱼群采食时的纹理特征和形状特征代
