Review of marine livestock ecological urbanization hypothesis and marine ranching construction key-technology against blue growth background

In recent years, overfishing, pollution and unsustainable coastal development have caused irreversible damage to habitat, ecosystem functions and biodiversity. Moreover, several problems such as transformation and upgrading of tradition fishery and culture industries, environmental pollution, declining of fishery resources, small-scale fisheries under threat have come into notice in recent years, attracting more and more scientists to study related fields. The related framework to solve above problems is most remarkable for the " blue growth”projects proposed by FAO and" marine ranching”proposed by China. Both" blue growth”and" marine ranching”frameworks are promoting the sustainable use and conservation of renewable resources on global and regional scale. However, under new circumstances, with the evolution of new framework, new trends in the evolution of environmental integrity and technical feasibility should come into being. In this paper, we discussed the central target, work and potential problems of marine ranching construction. Thus, we summarized the main current techniques of" blue growth”and" marine ranching”framework, integrated the relative techniques and framework of urban ecology, and proposed marine livestock ecological urbanization hypothesis-based marine ranching technical procedures. It entails marine livestock ecological urbanization hypothesis-based marine ranching sites selection and design, habitat construction, enhancement and behavioral control of marine biological resource and management technical procedures. Finally, we analysed the practical applicability of both relative techniques and technical procedure integration. The above framework and specific technical procedures are proving especially useful and posses reference significance in regard to scientific and practical applicability of marine ranching construction.
