Using CiteSpace, VOSviewer, and RStudio Bibliometrix bibliometric visualization software, we conducted a bibliometric analysis of research literature from the Web of Science (WOS), Google Scholar, and CNKI databases on seafood cold chain transportation from 2012 to 2023. Firstly, we performed keyword co-occurrence analysis on the sample to study the key areas of the current seafood logistics cold chain transportation field. Secondly, we analyzed and studied the hot topics in this field using keyword clustering and keyword centrality. Lastly, we studied the evolution and frontier of research hotspots in the seafood slogistics cold chain transportation field based on keyword burst analysis, and explored future research directions in this field through further interpretation of foreign hotspots. The specific analysis results are as follows:
According to the keyword frequency and burst analysis of hot research trends, we found the evolution of research hotspots in the seafood cold chain logistics field from 2012 to 2023. In the foreign keyword burst, the key focus from 2018 to 2023 was on prediction, growth, optimization, etc.; among which, "cold chain" was the most prominent term (burst strength of 5.02), which was a hotspot for foreign scholars. From 2017 to 2019, frequent food safety issues led scholars to shift their research focus to the food supply chain to ensure public welfare. Under the influence of the dual-carbon goals, scholars used mathematical models and genetic algorithms to solve agricultural product distribution vehicle route optimization problems from 2019 to 2020, seeking the optimal distribution routes under constraints of multiple time windows to reduce logistics costs, optimize vehicle routes, achieve low-carbon environmental protection, and enhance customer satisfaction. The outbreak of the COVID-19 pandemic exposed the shortcomings of cold chain logistics, leading people to pay more attention to food safety and the development of fresh agricultural product cold chain transportation.
Through analysis of the keyword clustering knowledge map, key topics in the seafood cold chain logistics field include seafood refrigerated transportation, product quality, agricultural product cold chain systems, big data empowerment, and agricultural product e-commerce. Refrigerated trucks and cold chain circulation are hot topics in agricultural product cold chain transportation. The integration of agricultural product supply chains and chain supermarkets mainly focuses on agricultural product quality issues. Vehicle route optimization, cold chain technology, and optimization models are components of agricultural product cold chain systems. Big data, "Internet +," and fresh e-commerce all fall under the category of agricultural e-commerce. Agricultural e-commerce has expanded the sales scope of agricultural products and is a key area of interest for scholars.
In this study, using CiteSpace, VOSviewer, and RStudio Bibliometrix, it was shown that the number of publications in this field has been growing rapidly each year, especially after 2019. Among the top countries/regions, China ranks first with 158 publications, followed by the United States with 142 publications, indicating that China and the United States are leading in this field. In recent years, China's rapid scientific development is closely related to strong national support for scientific research and talent cultivation. However, compared to China, the United States has higher Multiple Country Publications (MCP) and MCP_Ratio indices, representing a more solid research foundation and outcomes in this field. Besides China and the United States, the United Kingdom and Canada have lower publication volumes but higher MCP_Ratio indices, indicating that scholars from these countries maintain close contact with scholars from other countries and actively engage in cooperation. The country cooperation network shows that China and the US are in central positions with the thickest boundaries between them, representing a very close cooperative relationship. The interwoven connections between countries indicate that scholars and institutions have made great efforts to eliminate academic barriers, promote academic cooperation, and exchange knowledge.
In the top 10 journals, six have an impact factor (IF) higher than 5, indicating a high demand for research on seafood cold chain logistics, and most of the research in this field is of high quality. It is worth noting that articles by high-output authors in seafood cold chain logistics are almost all published in very high IF journals, and their commonly used keywords are highly consistent with research hotspot keywords, indicating that these topics are the focus in recent years, and scholars in this field should actively pay attention to these topics. The overlay analysis shows that in the past decade, the main disciplines at the forefront of research are Discipline One (mathematical operations, systems, related mathematics) and Discipline Seven (veterinary, animal sciences), indicating that research in this field has been integrated with research in multiple disciplines. Scholars should consider the cross-disciplinary integration of these fields to achieve significant progress.
From an application perspective, international scholars in the seafood cold chain logistics field typically combine modern management theories with quantitative research methods such as system optimization and algorithm modeling, using data to support the development of the agricultural cold chain logistics industry. This research approach provides valuable experience for theoretical construction and multidisciplinary application. Some scholars conduct research from the perspectives of agricultural economics and big data applications, actively engaging in distribution vehicle route optimization and modern cold chain logistics system construction. However, due to the influence of logistics infrastructure construction and policies, research on seafood cold chain logistics still faces problems such as dispersion, stage specificity, and insufficient depth.

Reviewer 2 Report
Comments and Suggestions for AuthorsSummary
The aim of this paper is to use literature visualization software to examine the primary foci of the seafood cold chain logistics literature and use this information to identify research gaps and propose future directions.
It is an extremely well structured and written paper, solid in its analysis and presentation as well as the conclusions drawn. The Figures are interesting and appropriate but the Tables are not properly referred to in the text.
Specific comments by line:
I suggest you revisit the first 3 paragraphs of the introduction to ensure clarity and flow. Your first paragraph captures everything so a suggestion could be to expand each statement using information found later in the first 3 paragraphs. For example, line 53 – not really ‘therefore’ as the two statements are not linked. That paragraph is about the rigor of food safety requirements and not cold chain logisitics management. It could be the start of the following paragraph.
Line 57 – this is a separate issue and should not come under cold chain logistics.
Figure 1/line 89. This is not referenced in the text and should come in section 2.
Line 124: why these dates?
The Tables need to be referenced in the text – the titles are clear but they must have a ‘home’ within the text.
410. What is a foreign scholar? Foreign for whom?

With the improvement of living standards, there is increasing attention to nutritional value of food [1]. The proportion of fresh foods, such as seafood, in daily diets is steadily rising [2, 3]. However, preserving the freshness of seafood at room temperature is challenging, necessitating the support of cold chain logistics for storage, transportation, and distribution [4-6]. Additionally, recent food safety incidents have improved public awareness and concern about food safety [7]. Health-conscious eating habits has become a key issue in people's lives, leading to a growing focus on the quality and safety of fresh foods [8, 9]. Ensuring the quality of fresh foods requires maintaining their safety and smooth flow throughout the distribution process [10, 11].
Global requirements for fishery products are becoming increasingly stringent [12]. The FDA Food Safety Modernization Act (FSMA), enacted by the United States in 2011, enhanced the FDA's regulatory authority over domestic and imported food safety supervision, imposing more rigorous food safety requirements on food manufacturers [13-15]. In 1997, the European Union introduced the Seafood Quality Standards Act, mandating that food suppliers comply with specified quality assurance provisions and establish various seafood quality standards to ensure the provision of high-quality seafood that is healthy, safe, nourishing, and environmentally beneficial [16-18]. In China, policies have also played a crucial role in promoting the rapid rise of cold chain logistics [19]. Such as, Chinese government's "Development Plan for Agricultural Product Cold Chain Logistics" in 2010 and the "14th Five-Year Plan for Cold Chain Logistics Development" in 2021 have provided a top-level design for the continuous improvement of the industry [20, 21]. Therefore, cold chain logistics management plays a pivotal role in ensuring the quality and safety standards of fishery products [22].
Effective utilization of cold chain logistics is crucial not only for maintaining the freshness and quality of seafood but also for minimizing post-harvest losses, thereby enhancing economic benefits and promoting environmental sustainability [23-26]. The seafood industry plays a vital role in the global food supply chain, ensuring food safety and nutrition [27, 28]. Cold chain logistics, which involves temperature control and transportation of seafood, is indispensable for maintaining the quality and safety of seafood products [29, 30]. With the rapid growth of the global economy and the increasing demand for high-quality seafood, cold chain logistics has been widely adopted [31, 32]. Consequently, an increasing number of scholars are exploring seafood cold chain logistics.

It can be seen that the field of cold chain logistics has received the attention of governments and has received policy support.
Cold chain logistics management plays a pivotal role in ensuring the quality and safety standards of fishery products [22]. The effective use of cold chain logistics is essential not only to maintain the freshness and quality of seafood, but also to raise standards in the cold chain logistics industry[23-26].

Despite the rapid growth of the seafood industry, comprehensive reviews of research in the field of seafood cold chain logistics are relatively scarce. Analyzing and summarizing past research is a valuable academic endeavor, as the theoretical and empirical contributions of individual studies are crucial for advancing knowledge within an academic field [33-36]. Bibliometric analysis can elucidate development trends in seafood cold chain logistics, identify research hotspots, and highlight emerging directions, thereby guiding future research choices and planning [37-40]. Although numerous researchers have reviewed various aspects of seafood cold chain logistics, such as energy consumption analysis [41], electrode materials [42, 43], and route design [44, 45],few have employed bibliometrics to explore research hotspots, developing trends, or scientific advancements in this field [46, 47].
After modification：
The number of publications per year serves as a valuable indicator of growth trends in Seafood Cold Chain Logistics research. Figure 1 illustrates the annual publication and citation counts of Seafood Cold Chain Logistics documents, revealing an exponential surge of publications in the Seafood Cold Chain Logistics field over the past 12 years. Despite the rapid growth of the seafood industry, comprehensive reviews of research in the field of seafood cold chain logistics are relatively scarce.

Comments 4: Line 124: why these dates?
Response 4: Thank you for your questions. In our research, we chose the time interval from January 1, 2012, to December 31, 2023. This period was selected because the United States, the European Union, and China successively implemented policies related to cold chain logistics, explicitly emphasizing its importance for food safety. These policies have heightened scholars' interest in research within the seafood cold chain logistics field, leading to a gradual increase in the number of related publications.
The FDA Food Safety Modernization Act (FSMA), enacted by the United States in 2011, enhanced the FDA's regulatory authority over domestic and imported food safety supervision, imposing more rigorous food safety requirements on food manufacturers.
In 2013, the European Union issued the EU Refrigeration Equipment and Cold Chain Logistics (Directive (EU)2015/8), which has carried out comprehensive specifications and requirements for the field of cold chain logistics, including detailed regulations on temperature control, health and safety measures in cold chain logistics. It also requires enterprises to adopt timely and transparent regulatory means in cold chain logistics to ensure food safety and quality.
In China, the Food Safety Law of the People's Republic of China came into effect in 2015, making comprehensive provisions on the production, distribution, sale and import of food. Among them, there are detailed regulations on temperature control, health measures, food testing and other aspects of cold chain logistics, requiring enterprises to take effective measures to ensure food safety in cold chain logistics.
Comments 5: The Tables need to be referenced in the text – the titles are clear but they must have a ‘home’ within the text.
Response 5: Thank you for your question, according to your suggestion we have quoted the table and headings in the body, here we do not list the changes, but in the revised manuscript highlighted in red colour.
Comments 6: 410. What is a foreign scholar? Foreign for whom?
Response 6: Thanks for your advice, we have deleted the foreign from the foreign scholar. The scholars in this manuscript should be scholars in the field of seafood cold chain logistics. The Change the foreign scholar to scholar and mark the revised article in red colour.
