“…Many scholars analyzed the evolution of marine ranch policies. Using a potential Dirichlet allocation model, Qin and Sun quantified the policy texts from a database of 25 marine ranches in Shandong province, aiming to identify the factors influencing the policy themes (Qin and Sun, 2021). Employing content analysis methods and ROSTCM software, Yu and Zhang conducted an empirical analysis of 92 policy documents.…”

This study establishes a three-party evolutionary game model that includes marine ranch firms, consumers, and the government, with a focus on the digital transformation pattern of marine ranching. Subsequently, the researchers conduct gaming and simulation to analyze the government subsidy strategy in the digital transformation of marine ranching. The following findings are derived: (1) Government subsidies have the potential to facilitate the digital transformation of marine ranches, benefiting both the supply and demand sides. Government subsidies positively influence both the digital transformation of marine ranch firms and the involvement of consumers in this transformation process. (2) The findings from the evolutionary game system demonstrate that alterations in the cost–benefit dynamics of each participant lead to adjustments in the steady state, thereby prompting the government to adapt its optimal subsidy strategy. (3) More government subsidies are not always better. Excessive government subsidies will destroy the stability of the evolutionary game system, which is not conducive to the realization of the digitization of marine ranch. (4) Subsidizing consumers is more effective in driving the digital transformation of marine ranch than subsidizing marine ranch firms. Subsidies to marine ranch firms will destroy the stability of the evolutionary game system, whereas subsidizing consumers contributes positively to its stability.

“…The Chinese government attaches great importance to the development of marine ranching, which is characterized by the restoration of marine environments, the maintenance of marine biodiversity, and the benefits of ecological importance (Qin and Sun, 2021). Shandong Province has constructed numerous national-level marine ranching demonstration areas in places with superior coastline and geographical location to provide scientific experience for the development and management of marine ranching worldwide.…”

The goal of this study was to evaluate the trace element pollution in a marine ranching area in China based on molecular responses (expression of metallothionein and antioxidant enzyme genes), and biochemical biomarkers (metallothionein content, antioxidant enzyme activities, and malonaldehyde level) in four indicator species. We collected samples of two fish (Lateolabrax maculatus and Sebastes schlegelii), one crustacean (Charybdis japonica), and one gastropod (Rapana venosa) from the western Furong Island marine ranching area and from an adjacent area in March 2022 and measured the trace element content in these indicator species as well as in the seawater and sediment. We found that the bioaccumulation characteristics of trace elements and the response patterns of biomarkers were species specific. Moreover, not every biomarker was significantly correlated with environmental trace element content. We then established two biomarker combinations indicative of trace element pollution in seawater and sediment, respectively, based on the correlation between biomarkers and trace element contents. The selected biomarkers were integrated using integrated biomarker response version 2 (IBRv2). IBRv2 values in the studied marine ranching area were lower than those in the adjacent area. Additionally, these values were consistent with the bioaccumulation of trace elements in the indicator species, the integrated trace element pollution index for seawater, and the potential risk index for sediment. These results show that this multi-biomarker and multi-species IBRv2 approach provided a comprehensive diagnosis of trace element pollution in the marine ranching area. Therefore, its application may be beneficial for marine environmental monitoring and management in view of the ecotoxicological impact of pollutants on organisms.

IntroductionTheoretically and practically, studying the zero-carbon production supervision of marine ranching is crucial to the attainment of my country’s fishery carbon peak and carbon neutral goals.MethodsThis study introduces a third-party detection agency to construct a tripartite evolutionary game model based on the possibility of problems such as a lack of government supervision and imperfect detection mechanisms, through an analysis of the evolution stability and evolution path of each participant’s strategy choice, the mechanism of each element’s influence on the tripartite strategy choice is revealed, as well as the evolution law of the tripartite game.Results① The change in strategic choice of each participant is significantly influenced by the change in strategic choice of the other participants, and the comprehensive consideration of the maximization of the comprehensive value of each participant is conducive to the development of all three parties. ② Government efforts to increase low-carbon subsidies and penalties will aid in promoting the normative behavior of zero-carbon production by marine ranching businesses and the rejection of rent-seeking by third parties. ③The accountability of higher-level governments for the dereliction of duty of regulatory agencies is particularly important to enhance the robustness of zero-carbon production of marine ranching enterprises.DiscussionIn this study, the ideal state of carbon balance of Marine ranching enterprises is taken as the condition to establish a tripartite evolutionary game, and the numerical simulation analysis results based on the model’s evolutionary stable equilibrium put forward countermeasures and suggestions for the government to improve the supervision mechanism of zero-carbon production of Marine ranching. In order to provide reference for the development of the marine ranching industry and promote the realization of zero emissions in the production activities of the marine ranching industry.
