Abstract:In recent years, with the development of Marine ranching, various problems emerge, in order to understand the development trend of Marine ranching in China. This paper searched the literature information in the research field of " Marine ranching " by topic, and used Bibexcel, Ucinet, Netdraw, SPSS and other software to analyze the knowledge map of the retrieved data. The results show that the total number of posts is on the rise, which can be divided into three stages; Marine ranching, artificial reef and fishery resources are the Keywordswith the highest frequency in the field of Marine ranching research and become the research hotspot in this field; An academic group with 45 core authors has been formed. The centrality analysis of core authors indicates that Chinese scholars have different levels of research ability, and they still have some shortcomings such as difficulty in grasping the research trends and less academic exchanges in the research field; The characteristics of scholars" factions have appeared, but they have not formed yet. From bibliometrics method, this paper analyzes Marine research and research hotspot of the ranch, specifically in the sea ranch development in our country construction is still in its infancy, facing many problems, the accuracy and depth is not enough, the lack of forward-looking and strategic vision, thus offer the theoretical foundation for the further research of Marine animal husbandry.
