A long term monitoring program is necessary to ensure the population safety. We propose to continuous study the ecology of the Chinese white dolphin, such as the spatial and temporal demography of the dolphins and their prey species. In addition, we also propose to study the behavioral and physiological responses of prey fishes caused by underwater noise in case of the development of offshore wind farm. There are five main tasks in this proposal. (1) Survey for the Chinese white dolphin, we plan to conduct 42 boat surveys to cover the dolphin’s habitat from Miaoli to Tainan. (2) Workshop for dolphin survey, we will provide a two-day program that teaches field and lab skills of dolphin survey. (3) Questionnaire survey for fishermen, we will visit and talk to local fishermen to understand their attitude and opinions to the dolphins and preserve. (4) Fish community study, we will examine and compare the community structures between different water depth along the coast of dolphin habitat. (5) Stress physiology, we will conduct noise treatments on fish to understand their behavioral and physiological responses to stress. The expected results include the spatial and temporal population dynamics of the Chinese white dolphin, the composition and abundance of their prey fish, and their responses in behavior and physiology to noises that may provide insights of conservation management and coastal development for the policy and law makers.中華白海豚族群生態食餌棲地監測噪音與震動壓力生理Chinese white dolphin (Sousa chinesis)population ecologyprey-habitat monitoringacoustic noise and vibrationstress physiology
