The ichthyofaunal composition of the floodplains of the Lower Cross River was investigated and compared in order to promote its management. A total of 5211 fish were sampled for 12 consecutive months from commercial landings of artisanal fishers from three sampling stations. We estimate 77 species distributed into 52 genera, 29 families and 9 orders, both of freshwater (88.66%) and euryhaline (marine intrusive) fishes (11.34%), with averagely 1-3 species per genus. The fishes composed mainly Perciformes, the least being Polypteriformes and Clupeiformes.. The five most abundant fish families are the Bagridae &
