“…Weldrick and Jelinski conducted a comparative analysis of d13C and d15N signatures and the isotopic niches of mussels cultivated within a Canadian integrated multi-trophic aquaculture facility, they assessed the dietary impact of aquaculture-derived effluent on the mussels (Weldrick and Jelinski, 2016). Scholars have found that there are biased technological advances that have contributed significantly to the reduction of mariculture pollution (Ren, 2021). The promotion of high-quality mariculture industry poses new requirements for marine policies .…”

IntroductionThe expansion of fishery development from offshore to deep-sea areas has become essential for countries to address environmental constraints and ensure food security. This study aims to establish a cooperative development model for deep-blue fishery involving the government, fishery enterprises, and consumers.MethodsWe constructed an evolutionary game and simulation model to analyze the government's deep-blue fishery subsidy strategy. The model considers the interactions between the government, fishery enterprises, and consumers, evaluating how different subsidy strategies influence the development of deep-blue fishery.ResultsOur results demonstrate that government subsidies can stimulate the growth of deep-blue fishery from both the demand and supply sides. Specifically, the likelihood of government subsidies positively affects fishery enterprises' engagement in deep-blue fishery development and consumers' willingness to purchase deep-blue fishery products. The evolutionary game system reaches different steady states based on the cost-benefit changes for the government, fishery enterprises, and consumers, leading to various optimal subsidy strategies.DiscussionThe findings indicate that the amount of government subsidy should be optimized rather than maximized, as excessive subsidies may not yield proportionate benefits. Additionally, subsidizing fishery enterprises proves to be more effective in promoting the development of deep-blue fishery compared to subsidizing consumers. These insights can guide policymakers in designing efficient subsidy strategies to foster sustainable deep-sea fishery development.

“…The highest upgrading degree of fishery production was Tianjin, and the lowest was Liaoning and Guangxi. Later, with the establishment of China's strategic goal of building a blue granary and a marine power, all regions continue to strengthen the guidance of relevant policy, and the construction of new offshore equipment such as marine ranch entered an acceleration period (Ren, 2021b). With its own policies, resources and late development advantages, the upgrading index of marine fishery culture production structure in Hainan, Liaoning and Shandong provinces has been growing rapidly for a long time, with an average annual increase rate of more than 40%.…”

The marine environment pollution is becoming an important factor that restricts the sustainable development of mariculture in China. This study takes 10 Chinese coastal provinces (cities) as the study area, based on the rationalization and upgrading dimensions of industrial structure, and innovatively constructs an analytical framework of marine environmental pollution and offshore aquaculture structure to identify the intrinsic relationship between them; and introduces a spatial econometric model to alleviate the estimation bias caused by the public goods attribute of marine environment and improve the reliability of research conclusions. The results show that: (1) The rationalization of the offshore aquaculture structure in China is relatively weak, showing a “concentrated and contiguous” distribution pattern towards the developed aquaculture areas; at the same time, but the differences between regions are expanding; (2) The rationalization and upgrading of the offshore aquaculture structure are affected by the pollution of the marine environment. The degree of upgrading shows different trends; (3) There is a significant spatial adjacency and threshold effect of the negative impact of marine environmental pollution on offshore farming structure. However, due to the limitations of data, the accuracy of our data and the effectiveness of the measurement of industrial structure indicators still need to be improved. Therefore, governmental departments should consider the development of the surrounding areas as well as the pollution emission in the region, and jointly promote the optimization and adjustment of China’s offshore aquaculture structure through the construction of a coordinated management mechanism of marine pollution prevention and treatment.
