Abstract:Pelophylax nigromaculatus ,an economically important species within the genus Pelophylax,serves both culinary and medicinal purposes due to its nutrient一rich meat characterized by high protein,low fat,and low cholesterol content. In recent years,the artificial breeding of Peloph ylax nigromaculatus has expanded rapidly in China. However, frequent disease outbreaks caused by non一 standardized breeding techniques and poor environmental management have severely impacted breeding efficiency. This paper systematically outlines the biological characteristics of Pelophylax nigromaculatus ,key technical aspects of its aquaculture,and the primary features of its major disease. It emphasizes the critical importance of implementing scientific breeding management and strengthening disease prevention development of the industry,thereby providing a theoretical foundation for practical aquaculture practices.

黑斑蛙(Pelophylaxnigromaculatus)属于蛙科类动物,是各地常见的蛙类。随着蛙类消费需求持续攀升,市场价格稳步上涨,养殖经济效益显著。我国黑斑蛙养殖产业呈现快速发展态势,养殖区域从传统的南方省份(如湖南、湖北、浙江等)逐步扩展至北方地区(如河南、河北、辽宁等),基本实现全国范围覆盖。2024年,全国养殖产量突破11万吨,成为淡水养殖中增速最快的种类之一[1]。然而,蛙类养殖业还存在盲目追求产量、超密度养殖、废水随意排放及养殖成本高等问题[2]。
近年来,我国农业农村部将“稻一蛙\"综合种养模式列为重点推广的生态种养技术之一,并在长江中下游、华南等水稻主产区形成规模化应用,单位面积综合经济效益得到有效提升[3]。研究表明,稻蛙模式下蛙类残饵和排泄物可作为有机肥替代部分化肥,减少氮磷排放,降低面源污染风险。同时,蛙的活动改善土壤结构,增强通气性,促进水稻根系生长及养分吸收效率4。同样,适当的增加放养密度可以提高牛蛙的肠道菌群多样性[5]。
“稻一蛙\"综合种养模式不仅提高了单位土地产出效益,实现“一地双收”,还通过生物间的互利共生关系,显著提升了资源利用效率,兼具经济价值与生态效益,为蛙类养殖产业的可持续发展提供了新思路[6]。
黑斑蛙生物学特性
黑斑蛙成体表现出显著的性别二态性。雄蛙体型稍小,头部呈长椭圆形。四肢粗短,后肢肌肉发达,趾间具全蹼。成体背部呈深绿、黄绿或棕灰色,分布不规则暗斑,腹面纯白无斑纹[7]。……
