摘 要:通过对友好林业局自然资源现状、林蛙养殖的现状、养殖规模、养殖方式、管理措施、政策扶持以及阻碍林蛙养殖发展的若干问题的调研分析,提出发展集约化林蛙养殖,加大林蛙繁殖、天然饵饲、品种优化等科技研发力度等促进林蛙产业发展应采取的相应对策。Based on the investigation and analysis of the status quo of natural resources of the Youhao Forestry Bureau,the current status of Rana amurensis Boulenger breeding,the scale of breeding,the breeding methods,management measures,policy support,and several issues that hinder the development of Rana amurensis Boulenger breeding,this paper proposes to develop intensive Rana amurensis Boulenger breeding and increase the number of Rana amurensis Boulenger.Corresponding countermeasures should be taken to promote the development of Rana amurensis Boulenger industry,such as scientific research and development efforts such as Rana amurensis Boulenger breeding,natural bait feeding,and species optimization.
