The growth parameters of three species were studied for the first time in the AlMassira Dam. A total of 137 individuals were examined during this study between September 2020 and January 2021. The estimation of growth parameters was carried out by size structure analysis using FISAT II software. The growth parameters of Micropterus salmoides, Cyprinus carpio and Oreochromis niloticus are respectively: L∞= 35.11 cm, K= 0.58 year-1, t0= 0.57 year; L∞= 44.85 cm, K= 2.60 year-1, t0= 1.27 year and L∞= 45.26 cm, K= 0.32 year-1, t0= 0.33 year. Thus, the Von Bertalanffy growth equations are written respectively: L(t) = 35.11 (1-e-0.58 (t+0.57)), L (t)= 44.85 (1-e-2.60 (t+1.27)) and L (t)= 45.26 (1-e-0.32 (t+0.33)).
Key words: Al-Massira Dam / Micropterus salmoides / Cyprinus carpio / Oreochromis niloticus / Growth
