The highest abundance species in the collected area were Liza abu, Carassius auratus, Tilapia zillii and Oreochromis aureus (36.71, 31.55, 9.84 and 5,63% respectively). Diversity index (H) ranged 0.92-1.89, Richness (D) 0.95-2.59 and Evenness (J) 0.39-0.78 for study area, the entire similarity 52.91% according to Jaccared similarity index. | ||
