A composite environmental stress control system for monitoring aquatic animal behavior

Abstract

The invention belongs to the technical field of aquatic organism research, specifically a composite environmental stress control system for monitoring aquatic animal behavior, comprising a monitoring unit, a temperature control unit, a dissolved oxygen control unit, and a carbon dioxide partial pressure control unit. The monitoring unit includes a water basin, an inner partition cylinder, and a camera. The inner partition cylinder separates the internal space of the water basin into an animal placement area and an equipment placement area. The water intake end and return end of the temperature control unit, the nitrogen output end of the dissolved oxygen control unit, and the mixed gas output end of the carbon dioxide partial pressure control unit are all located in the equipment placement area of the water basin. The invention can precisely and rapidly regulate water temperature, dissolved oxygen, and carbon dioxide partial pressure in a laboratory environment, allows for quick disassembly and assembly to adapt to multiple usage scenarios and different experimental scales, and can effectively eliminate the impact of device-related accessories on the normal physiological behavior of the animals, thereby meeting the needs of current behavioral research for refined experimental platforms.
