The application relates to the field of aquaculture, in particular to a culture method of longsnout catfish (Leiocassis longirostris) in the culture of penaeus vannamei, which comprises the following steps: pond preparation, fry stocking, feed feeding, water quality management, daily management, fishing and harvesting, etc. The application establishes a multi-nutrient level culture mode of fish and shrimp symbiosis, fully utilizes the water space of the culture pond of penaeus vannamei, improves the water utilization rate of the pond, improves the production efficiency, utilizes the habits of longsnout catfish and penaeus vannamei, plays the effect of fish and shrimp ecological comprehensive disease prevention, improves the growth environment of fish, improves the feed utilization rate, reduces the total feed coefficient, reduces the wastewater discharge, and improves the energy efficiency of aquaculture. The application is simple in operation and easy to popularize.

This invention discloses a method and system for regulating the hatching environment of *Catfish simonii* based on multi-parameter sensing via the Internet of Things (IoT), specifically relating to the field of multivariable environment automatic control technology. It addresses the problem of inaccurate multivariable control commands in existing collaborative control methods due to reliance on distorted data when sensing network dynamics. By acquiring multi-parameter monitoring data of the water body, network topology information, and equipment status data, it establishes spatial gradient change predictions for key parameters to diagnose node performance degradation and detects equipment start-up and shutdown events to analyze transient response curves and determine abnormal coupling relationships. Subsequently, it identifies affected parameters and regions, and performs reliability assessment and correction on data from degraded nodes. Finally, based on the corrected reliable data, it generates collaborative control commands for heating, aeration, and water flow equipment. This achieves robust collaborative control under conditions of sensing uncertainty, improving the stability and accuracy of multivariable environment control.
