As the basic link of livestock product supply, animal husbandry is of great significance to ensure the quality of animal products and the healthy development of industrial economic benefits. At present, the information monitoring technology in animal husbandry is still lagging behind, and the penetration rate is not high. It is impossible to accurately and effectively grasp the actual conditions of the farm animals themselves and their living environment. On the basis of sorting out and summarizing the existing research results of wearable technology, combining with the actual situation and characteristics of animal husbandry in China, the working principle, information monitoring technology and wearable monitoring methods of wearable information monitoring in animal husbandry were mainly analyzed and discussed. The research trends were summarized as follows: the development of information acquisition from manual acquisition to automatic acquisition; wearable sensors would be miniaturized and flexible; signal processing and information transmission would develop towards diversification, compounding and intellectualization; the way of information monitoring would be systematic, holistic and adaptive; and the application of wearable information monitoring technology would improve the level of aquaculture management and decision-making.
