光伏渔业系统中水产光照偏好性与遮阴对生态渔业影响的研究进展与展望

Progress and prospect on aquatic light preference and the effect of photovoltaic panel shading on aquaculture in photovoltaic fishery systems

光伏渔业系统遮阴减少光照强度,从而对水产养殖产生影响。在碳达峰、碳中和目标政策背景下,明确光伏渔业系统下遮阴对水产养殖的影响具有重大现实及战略意义。基于此,文章阐述了光伏渔业系统中水产养殖现状,说明了水产动物摄食与生长所需的最适光照强度,归纳了光伏板遮阴对藻类与沉水植物生长以及水质的影响,分析了现阶段光伏渔业系统的主要技术问题及研究重点。最后,从光伏渔业系统养殖品质、养殖现代化、降本增效及市场前景4个方面进行展望,为进一步开展光伏渔业技术研究与应用提供参考。

Due to the reduction of light intensity by shading,photovoltaic(PV)fisheries system has an impact on aquaculture.Under the policy background of“emission peak,carbon neutrality”,it is of great practical and strategic significance to clarify the impact of PV fishery systems on aquaculture.In this study,the current situation of aquaculture with the photovoltaic(PV)fisheries system was described.We elaborated and summarized the optimal light intensity required for aquatic animal feeding and growth,and the effects of photovoltaic panel shading on the growth of algae and submerged plants as well as the water quality.Beyond,the main technical problems at the present stage and research focuses in future of PV fishery systems were described.Finally,in order to provide reference for the research and application of PV fishery technology in China,we made the outlook of PV fishery system in terms of aquaculture quality,modernization of aquaculture,cost-saving and efficiency,and market prospects.
