“…In the water samples, the microbial community was dominated by Proteobacteria, which was followed by Actinobacteria, Cyanobacteria, and Bacteroidetes. Similarly, microbial communities in the marine ranching area of Laoshan Bay was dominated by Proteobacteria, which was followed by Cyanobacteria, and Actinobacteriota (Fang et al, 2021). In aquaculture ponds of shrimp Litopenaeus vannamei in Zhongshan, China, Proteobacteria was dominant, followed by Tenericutes, and Bacteroidetes .…”

Microorganisms colonize plastics in the aquatic environment but their composition on plastics used in aquaculture remains poorly studied. Microorganisms play a significant role in aquaculture in terms of water quality and the health of cultivated species. In the current study, we explored the composition of microorganisms on floating plastics and their surrounding water collected from ponds and open aquaculture areas. Using scanning electron microscopy, the diversity of microbial communities, primarily diatoms, and bacteria were identified on the plastic surfaces. Additionally, epifluorescence microscopy revealed that prokaryotes were colonized on all plastic samples from 0.1 to 29.27×103 cells/cm2, with a high abundance found in open aquaculture areas compared to ponds. Bacterial communities were characterized by 16S rRNA sequencing which showed that bacterial communities on plastics were dominated by Proteobacteria, Cyanobacteria, Bacteroidetes, and Actinobacteria. The level of these microbial communities on the plastics differed from those found in the surrounding seawater samples and the abundance of potentially pathogenic bacteria was higher in plastics than in seawater samples. Moreover, hydrocarbon-degrading bacteria were more abundant in the investigated plastic samples than in the water samples. This study contributes to the knowledge regarding the plastisphere community in aquaculture.

“…Countries have explored marine pasture models to solve the problems of seawater pollution (Tan and Lou, 2021). The marine pasture has played an ecological restoration function (Fang et al, 2021;Qin et al, 2021), which enhance the ecological safety level (Du and Gao, 2020). However, there are many risks and problems that affect the ecological restoration function.…”

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.

“…Marine ranching is different from traditional fishing and aquaculture, and it aims to create a three-dimensional, multi-level natural ecological space through the organic integration of various industries and the use of environmental engineering, biological control of resources, production support and other technologies. It is a marine economic complex that “grazes” in marine waters, islands and specific areas of the mainland coastal zone [ 12 , 13 ]. Marine ranching can solve the problems of improper utilization of marine resources, overfishing, and seawater pollution faced by mariculture [ 14 ], and is a critical way to protect the ecological environment of nearshore waters and efficiently produce marine fishery resources [ 15 ].…”
