Abstract

Purpose: This study aims to explore the physiological response to stress by analyzing the reddening of the abdomen when capturing Carcharinus perezii. Methods: This study collected data on the shark’s air and water temperature, heart rate, weight, and the reddening time after multiple captures during the capture process to analyze the shark’s predictive ability. Results: Through data analysis, there is a significant positive correlation between air temperature and water temperature. Multiple captures lead to a significant extension of the reddening time, indicating that multiple captures increase the physiological stress of sharks. Conclusion: Air and water temperature will cause a more severe physiological stress response to Carcharinus perezii. At the same time, through the specific data analysis of sharks, effective improvements can be made in reducing stress on sharks in future shark research.
