Weight-length relationship and relative condition factor of Micropterus salmoides (Lacépède, 1802), Cyprinus carpio (Linneaus, 1758) and Oreochromis niloticus (Linnaeus, 1758) caught in the Al-Massira Dam Lake

The current study describes the length-weight relationships and relative condition factors (Kr) of three species during the period (September 2020January 2021). For this purpose, 137 fish were sampled. The “size-weight”relationships thus established for each species are: Largemouth Bass: Tw = 0.0055...

Sumario:The current study describes the length-weight relationships and relative condition factors (Kr) of three species during the period (September 2020January 2021). For this purpose, 137 fish were sampled. The “size-weight”relationships thus established for each species are: Largemouth Bass: Tw = 0.0055Tl3.2816, Cyprinus carpio: Tw = 0.0148 Tl2.9417 and Oreochromis niloticus: Tw = 0.0304 Tl2.8386. These results showed positive allometry for the first species (Micropterus salmoides) and a negative one for the two other species. The relative condition factor (Kr) is higher than one, which shows that these species are in good conditions at the Al-Massira dam.
