本文以科特迪瓦河流中的沃氏沼虾为研究对象，研究了沃氏沼虾的体长、体重关系和条件因子。雄性和雌性的最大甲壳长度（CL）分别为63.00和53.60 mm。体长与体长、体重与体长、体重与体长的相关系数均达到极显著水平，r ~ 2> 0.76（P < 0.001）。在体长-体长关系中，异速生长系数（B）的范围为0.75 - 1.46，并根据所考虑的长度和组而变化。体长-体重关系的B值在2.55 ~ 3.30之间。虽然观察到三种异速生长类型，但总体上，M。vollenhovenii表现为负异速生长。条件因子（K）在雄性和雌性之间没有显著差异。K值从科特迪瓦东部到西部呈下降趋势。本研究首次提出了黑木耳异速生长及其生长条件因子的研究结果。科特迪瓦河流中的沃伦霍维尼此外，还建立了一个生物数据库，供渔业管理人员使用，并用于进一步研究该鱼种的生态学、生殖生物学和水产养殖潜力。
The length–length and length–weight relationships and condition factor for Macrobrachium vollenhovenii are described using samples collected from the rivers of Cote d’Ivoire. The maximum carapace lengths (CLs) registered for males and females were 63.00 and 53.60 mm, respectively. All relationships between body length and CL and weight and CL were found to be highly significant, with r2 > 0.76 (P < 0.001). In the length–length relation, the allometry coefficient (b) ranged from 0.75 to 1.46 and varied according to the considered length and groups. The value of b of the length–weight relationship varied from 2.55 to 3.30. Although the three allometry types were observed, overall, M. vollenhovenii exhibited negative allometry. The condition factor (K) did not significantly vary among males and females. The K value decreased from the eastern to western Cote d’Ivoire. The present study presents, for the first time, results on the allometric growth and condition factors of M. vollenhovenii from the rivers of Cote d’Ivoire. Further, a biological database is established for use by fishery managers and in further research on the ecology, reproductive biology and aquaculture potentialities of this species.
