摘　　要：采用相关性分析和通径分析研究了室内循环水和池塘养殖四指马鲅(Elentheronema tetradactylum)的体质量和12个形态性状之间的关系。结果显示,两个养殖群体的形态性状与体质量均呈极显著正相关(P<0.01),并且两个养殖群体各主要性状间的相关性达到极显著水平(P<0.01)。与室内循环水养殖群体体质量相关程度较大的形态性状依次为叉长、体长、头长、尾柄高和全长;与池塘养殖群体体质量相关程度较大的形态性状依次为全长、尾柄高、叉长、体长和体高。通径分析表明,体长、体高、头长、体宽和眼径对室内循环水养殖四指马鲅体质量的直接作用达显著水平(P<0.05),以上形态性状的直接和间接决定系数总和为1.418;全长、尾柄高、体高、躯干长、头长对池塘养殖群体的体质量直接作用均达显著水平(P<0.05),以上形态性状的直接和间接决定系数总和为0.968。结果表明,池塘养殖环境鱼体的变异系数较大有利于良种选育,而室内循环水养殖规格较均匀利于生产。不同养殖模式下,四指马鲅形态性状与体质量的相关性分析可为其规模化养殖和选育技术优化提供理论依据。We applied correlation analysis and path analysis to explore the relationship between the body mass and the 12 morphological traits of Elentheronema tetradactylum cultured in indoor circulating aquaculture system and aquaculture pond,which had significant correlation(P<0.05),and the correlation among the morphological traits of E.tetradactylum in the two systems was very significant(P<0.01).The descending order of morphological traits which affected on the body mass of E.tetradactylum in indoor circulating aquaculture system and aquaculture pond were fork length>body length>head length>caudal peduncle height>total length,and total length>caudal peduncle height>fork length>body length>body height,respectively.The path analysis reveals that body length,body height,head length,body width and eye diameter had significant direct effects on the body mass of E.tetradactylum in indoor circulating aquaculture system(P<0.05).The total length,caudal peduncle height,body height,trunk length and head length had significant direct effects on the body mass of E.tetradactylum in aquaculture pond system(P<0.05).Besides,the total decision coefficients of those morphological traits to the body mass were 1.418 and 0.968 in indoor aquaculture system and aquaculture pond,respectively.The results reveal that larger variation coefficient of fish in aquaculture pond is conducive to the breeding of improved species,while more uniform specification of indoor circulating water culture is conducive to production.In different aquaculture environment,the correlation analysis of morphological traits and body mass of E.tetradactylum can provide theoretical basis for its large-scale cultivation and breeding technology optimization.
