Abstract

Overview

With the increasing use of wind power, concerns have arisen about its potential ecological impacts on marine ecosystems, particularly the effects of electromagnetic radiation.

Findings

This study investigates the impacts of varying strengths of electromagnetic fields (0mT to 2.0mT) on two species of commercially important marine fishes: the large yellow croaker (Larimichthys crocea) and the black sea bream (Acanthopagrus schlegelii).

• At higher field strengths (1.5mT and 2.0mT), a reduction in swimming velocity was observed in both species, indicating a behavioral change.
• Antioxidant enzymes were noted to have a protective effect against the electromagnetic fields.
• At a 2.0mT intensity, a stronger stress response and activated immune systems were recorded, especially in Acanthopagrus schlegelii.
• No significant impact on nutrient absorption was detected across the tested electromagnetic intensities.

Conclusion

The findings suggest differential sensitivities and potential reversible impacts of electromagnetic radiation, contributing to the development of early warning systems and preventive measures to safeguard marine life from effects related to offshore wind farms.
