Exploitation Parameters for the Mormyrus rume (Valenciennes, 1846) Population (Mormyridae fish) in the River Niger in Niamey (Niger, West Africa)
Mormyrus rume in the River Niger in Niamey is one of the most abundant species in the catch, and for rational management of this species, scientific information is more than necessary. This study assessed the exploitation parameters for this species. The data used to conduct this study were collected from August to November 2022. The generation of these parameters was made possible using StatView and FiSAT II software, with a mean annual temperature of 26°C. The initial catch length (Lc), natural mortality (M), fishing mortality (F), and total mortality were 18.74, 0.95, 0.39, and 1.34 per year, respectively. The current exploitation rate was 29% with a maximum of 40%. These initial results concerning the species under study in this part of the Niger River would serve as a basis for future studies in the context of sustainable and rational exploitation of Mormyrus rume.
