Length-weight relationships and condition factor of Oreochromis niloticus and Citharinus citharus in lower river Benue, Nigeria
Author(s): Laurat HT, Isiyaku MS and Akange ET
Abstract: The length-weight relationship and condition factor of two fishes were studied so as to infer the conditions of the Lower River Benue suitable for fish habitation. The species of fish selected (
O. niloticus and
C. citharus) are known to be harden and prolific. 114 samples of
O. niloticus and 104 samples of
C. citharus were obtained from the Wurukum landing site at Makurdi. The LWR protocol were administered on the samples and the results obtained indicated that the growth pattern (b) for
O. niloticus (0.332: female and 0.365: male) and
C. citharus (1.458: female and 1.421: male) were negative allometric and markedly far from isometric growth pattern (3). It was also established that the condition factors of the two species:
O. niloticus (1.48±0.13: female and 1.32±0.09: male) and
C. citharus (1.57: female ±0.11 and 1.34±0.11: male) were lower than values obtained of the same species in other water bodies. It was concluded that the comparatively lower values recorded in this study were as a result of the unfavorable water physicochemistry and food scarcity in Lower River Benue.
