Helminthes Load in Two Species of Fish of River Benue: Case Study of Ibi Fishing Site

Abstract

This study was undertaken to compare helminthes parasite load in relation to the sexes of Clarias gariepinus and Oreochromis niloticus of River Benue at Ibi fishing site and their significant differences. A total of one hundred and fifty two (152) individuals Clarias gariepinus and Oreochromis niloticus were caught and 76 each in the dry season rainy season. A T-test statistical analysis was used. Total helminthes load observed in C. gariepinus for both seasons was 139.00. The females had higher helminthes load (50.36%) while the males had lower (49.64%). Table 2 shows helminthes load of O. niloticus in both seasons. Total helminthes load observed in O. niloticus for both seasons was 93.00. The females also had higher helminthes load (67.74%) while the males had lower (32.36%). Total helminthes load observed in both species was 232.00. The females also had higher helminthes load (57.33%) while the males had lower (42.67%). There was no significant difference (p>0.05) in the helminthes load in both species. However, the female had higher helminthes load (mean: 2.76±0.36) and the male had lower (Mean: 2.58±0.35). There was no significant difference (p>0.05) in the helminthes load in Clarias gariepinus. However, the female had higher helminthes load (mean: 3.17±0.51) and the male had lower (Mean: 2.28±0.49). There was no significant difference (p>0.05) in the helminthes load in Oreochromis niloticus. However, the female had higher helminthes load (Mean: 3.05±0.42) and the male had lower (Mean: 2.13±0.44). It may be concluded that helminthes parasites exist in Clarias gariepinus and Oreochromis niloticus of River Benue at Ibi Fishing Site. Therefore, fish caught in this river should be treated against helminthes parasites.
