Physiological Effects of Ship Noise on Yellowfin Sea Breams (Sparus latus)

Objective: This research is to explore the effects of ship noise on the physiological status of yellowfin sea breams after short-time stimulations. Methods: The noise of the Pearl River Estuary was collected by the sound acquisition system, then the yellowfin sea breams were stimulated by the sound replay system, and finally the blood samples were tested every 24 hours. Results: The concentrations of red blood cells, white blood cells, lymphocytes and the hemoglobin in the experimental group are all higher than those in the control group after noise exposure. Conclusion: A short-time noise exposure can induce the stress response and promote the immune response to the adverse environment, and at the same time, excessive immune response will increase the death rate of yellowfin sea breams.
