Abstract

Climate change has increasingly impacted marine ecosystems, with marine heat waves emerging as a significant threat to coastal ecosystems and fisheries productivity. Marine heat waves, characterized by prolonged periods of anomalously high sea temperatures, can lead to severe ecological disruptions, including coral bleaching, shifts in species distributions, and declines in fish stocks. This article explores the causes and consequences of marine heat waves in the context of climate change, examines their impacts on coastal ecosystems and fisheries productivity, and discusses potential mitigation and adaptation strategies. By integrating recent scientific research and case studies, the article highlights the urgent need for effective management practices and policy interventions to address these challenges and safeguard marine resources for future generations.
