This invention provides a precise feeding decision-making method for shrimp based on multimodal acoustic-visual fusion, belonging to the field of intelligent control technology for aquaculture based on reinforcement learning. First, acoustic signals and video image data generated during shrimp feeding are simultaneously acquired and preprocessed. Then, a cross-modal alignment network is used to jointly represent and learn the acoustic and visual information, constructing a unified multimodal feature representation. Further, a self-supervised learning method is used to model the temporal evolution of shrimp feeding states, obtaining quantifiable feeding state indicators. Finally, these feeding state indicators are used as feedback input, and reinforcement learning is used to construct an adaptive feeding decision-making model, achieving dynamic optimization control of feeding amount and timing. This forms a closed-loop intelligent feeding technology system encompassing perception, representation, understanding, decision-making, and feedback.
