Ecosystem services, multifunctionality and diversity play a particular role in the management of carp pond aquaculture. These three concepts have been increasingly considered in sustainable aquaculture science and policymaking. However, the understanding and acceptance of sustainable aquaculture by fish farmers is a prerequisite for the successful implementation of such a targeted policy. Research on a fish farmers’ perception of ecosystem services, multifunctionality and diversification of carp aquaculture was carried out in Warmia and Mazury, Poland. The results of interviews showed that farmers have a deep understanding of the ecosystem services and multifunctionality of carp ponds. Production services were indicated as the most important, but the role of ponds in the preservation of biodiversity was another highly valued service. The greatest diversity of the activities, and conviction of their significant impact on the profitability of carp pond farming, was observed on farms with ponds of 1 to 50 ha. In the case of larger farms, the assessment of such impact was more moderate. All surveyed farms provided educational services regarding the ecological values of the ponds. All pond users, regardless of their size, highly rated the need for financial support for the conservation and development of biodiversity.

养鱼户对生态系统服务和鲤鱼池塘水产养殖多样化的看法：以波兰的Warmia和Mazury为例

生态系统服务，多功能性和多样性在鲤鱼池塘水产养殖的管理中发挥着特殊作用。这三个概念已在可持续水产养殖科学和政策制定中得到越来越多的考虑。但是，养鱼户对可持续水产养殖的理解和接受是成功实施这种有针对性的政策的前提。在波兰的Warmia和Mazury，对养鱼户对生态系统服务，多功能性和鲤鱼养殖多样化的认识进行了研究。访谈结果表明，农民对鲤鱼塘的生态系统服务和多功能性有深刻的了解。生产服务被认为是最重要的，但是池塘在保护生物多样性方面的作用是另一项高度重视的服务。在池塘面积为1至50公顷的农场中，观察到活动的多样性最大，并且确信它们对鲤鱼池塘养殖的获利能力有重大影响。对于较大的农场，对这种影响的评估更为温和。所有接受调查的农场都提供了有关池塘生态价值的教育服务。所有池塘使用者，无论其规模大小，都高度评价了为生物多样性的保护和发展提供财政支持的必要性。
