摘要
[目的]对我国海域4个不同地理群体曼氏无针乌贼的形态学特征进行比较.[方法]采用形态学分析方法,通过单因素方差分析和多重比较对舟山、温州、厦门和湛江4个不同曼氏无针乌贼地理种群的形态学差异进行比较.[结果]4个群体的腕式不一致,在测定的12项形态学指标中4个地理群体的胴长、胴宽、鳍宽、海螵蛸壳长、海螵蛸壳高存在显著差异.[结论]该研究结果可为曼氏无针乌贼的资源保护与开发提供一定的理论依据.
Abstract
[Objective] The aim was to compare morphological characteristics of Sepiella japonica in 4 wild populations in China sea.[Method] The morphological differences of 4 different Sepiella japonica wild populations (Zhoushan,Wenzhou,Xiamen and Zhanjiang) were compared through single factor variance analysis and multiple comparisons.[Result] The results indicated that the formulas of arms are not in consistent among 4 populations.Among 12 morphological indices,there were significant differences in mantle length,mantle width,fin width,eye distance,cuttlebone length and cuttlebone height.[Conclusion] These results provide a certain theoretical basis for protection and development of S.janonica resources.
