Key Points

• Fish diversity monitoring shows a link between rising marine temperatures and the emergence of southern species.
• The study highlights significant seasonal changes in fish populations based on continuous environmental DNA data.
• Analysis utilized environmental DNA methods to gauge biodiversity across different locations in Kesennuma Bay.
• Implications suggest the need for effective biodiversity assessments for sustainable fisheries management in affected regions.
