The length-weight relationships of two Siluriformes in Owalla and Eko-Ende Reservoir of Osun State, Nigeria
The length - weight relationships of two siluri formes Chrysichthys nigrodigitatus and Schilbe intermedius -from Owalla and Eko - Ende reservoirs were studied to provide useful information for the sustainable development of their fisheries. Length - weight data were analyzed, and LWR graphs were plotted using the sigma plot software. The b values in the LWR W = aLb varied between 3.01 and 3.58, revealing that the somatic growth of C. nigrodigitatus from Eko - Ende and that of Schilbe intermedius from both reservoirs had positive allometry, while C. nigrodigitatus from Owalla reservoir had an isometric growth. The maintenance of the ecological balance in the reservoirs will guarantee sustainable fisheries for these siluriformes.
