Introduction

The marine environment is a critical component of the global ecosystem, supporting biodiversity, regulating climate, and providing essential resources for human societies. Among its most significant contributions are the marine fisheries, which play a vital role in global food security, livelihoods, and economic development [1]. However, the increasing pressures of economic activities, particularly those related to trade and industry, have led to escalating levels of marine pollution, posing serious threats to the health of marine ecosystems and the sustainability of fishery economies. Marine pollution, encompassing a wide range of pollutants such as plastics, chemicals, and heavy metals, has profound impacts on marine life and habitats. The degradation of water quality and the destruction of critical habitats like coral reefs and mangroves can lead to declines in fish populations, thereby threatening the productivity of marine fisheries. At the same time, the trade of aquatic products, which is a key driver of economic growth in many coastal regions, is deeply intertwined with the state of marine environments. As trade expands, so does the potential for increased pollution, creating a complex feedback loop between economic activities and environmental health [2].

The challenge of balancing marine environmental protection with economic growth has become increasingly urgent as the negative impacts of pollution on fisheries and trade become more apparent. Policymakers are faced with the task of developing strategies that not only promote economic prosperity but also ensure the long-term sustainability of marine resources. This requires a nuanced understanding of the interrelationships between marine pollution, aquatic trade, and the fishery economy. This study aims to explore these interconnections through an empirical analysis based on a simultaneous equation model, which allows for the examination of bidirectional relationships between marine pollution, trade, and fishery economics. By investigating how these factors influence one another, this research seeks to provide insights into the dynamics at play and offer guidance on how to achieve a balance between economic growth and environmental sustainability in the marine sector. The findings of this study are intended to inform policy decisions and contribute to the development of integrated approaches that safeguard both the marine environment and the economic benefits it provides [3].

Discussion

The findings of this study highlight the complex and interdependent relationships between marine environmental pollution, aquatic products trade, and the marine fishery economy. By employing a simultaneous equation model, we were able to uncover significant bidirectional influences that emphasize the challenges of balancing economic growth with environmental sustainability in the marine sector [4]. The analysis reveals that marine pollution has a direct and detrimental impact on the productivity of marine fisheries. Pollutants such as plastics, chemicals, and heavy metals degrade water quality and harm marine life, leading to reduced fish stocks and biodiversity loss. This decline in fish populations not only threatens the ecological balance of marine ecosystems but also directly affects the economic viability of fisheries. As fish stocks dwindle, the ability of fisheries to meet market demand diminishes, leading to potential economic losses and increased pressure on remaining resources. Moreover, the negative effects of pollution extend to the trade of aquatic products. As the quality and quantity of fish available for harvest decline, the trade sector faces challenges in maintaining supply chains and meeting international standards for food safety. This can result in decreased export revenues, loss of market access, and a reduced ability to compete in the global market. The economic repercussions of marine pollution are thus felt across the entire value chain, from fishers to processors to exporters [5].

The study also demonstrates that economic activities, particularly those related to the expansion of trade and industrial development, contribute significantly to marine pollution. The pursuit of economic growth often involves increased industrialization, urbanization, and maritime transport, all of which can lead to greater discharges of pollutants into the marine environment. For example, the growth of coastal cities and the intensification of aquaculture can introduce pollutants such as nutrients, chemicals, and waste into nearby waters, exacerbating the pollution problem. The feedback loop between economic growth and environmental degradation is evident in this context. As economic activities expand, pollution levels rise, which in turn hampers the sustainability of the very resources that underpin these economic activities [6]. This vicious cycle poses a significant challenge to policymakers who must find ways to decouple economic growth from environmental harm. The findings of this study underscore the critical need for integrated policy approaches that address both environmental protection and economic growth. Traditional economic development strategies that prioritize short-term gains often fail to account for the long-term costs of environmental degradation. However, by adopting a more holistic approach that considers the interconnections between pollution, trade, and fishery economics, policymakers can develop strategies that promote sustainable development [7]. One key area of focus should be the implementation of stricter environmental regulations and standards that limit the discharge of pollutants into marine environments. These regulations could include measures to reduce plastic waste, control chemical runoff from agriculture and industry, and manage effluent from coastal development. Additionally, policies that promote sustainable fishing practices, such as catch limits, habitat protection, and the reduction of bycatch, can help preserve marine resources and ensure the long-term viability of fisheries. Another important aspect is the promotion of green technologies and practices in the trade and industrial sectors. By encouraging the adoption of cleaner production methods, waste reduction strategies, and sustainable supply chain management, governments and industries can help mitigate the environmental impact of economic activities. Incentives such as tax breaks, subsidies, and investment in research and development can further support the transition to more sustainable practices [8].

The study provides a foundation for future research on the interactions between marine pollution, trade, and fishery economics. Future studies could explore the specific mechanisms through which different types of pollutants affect marine ecosystems and economic outcomes. Additionally, research could investigate the effectiveness of various policy interventions in achieving a balance between economic growth and environmental protection in different regional contexts [9]. Further exploration of the social dimensions of this issue, such as the impact of pollution and economic changes on fishing communities, could also provide valuable insights for developing more inclusive and equitable policies. Understanding the local and global dimensions of these challenges is crucial for creating strategies that are both effective and adaptable to diverse conditions [10].

Conclusion

In conclusion, the discussion highlights the intricate and mutually reinforcing relationships between marine environmental pollution, aquatic products trade, and the marine fishery economy. The study underscores the importance of integrated policy approaches that consider the complex interplay between these factors to achieve sustainable development in the marine sector. By balancing the needs of the environment with the demands of economic growth, it is possible to foster a marine economy that supports both ecological health and long-term economic prosperity.
