Abstract: This study was carried out to determine the length-weight relationship and growth pattern of some selected fish species in Kubani Reservoir Kaduna State Nigeria: (Oreochromis niloticus (Linnaeus, 1758), Clarias gariepinus (Burchell, 1822), Pollimyrus petricolus (Daget, 1954), Schibe mystus (Linne, 1766) and Lates niloticus (Linnaeus, 1758) Kubanni Reservoir. A total of 439 freshly caught fish species were collected between (July and October 2018). Data on length and weight were subjected to ANOVA to determine statistical significance (P<0.05). The results revealed that Oreochromis niloticus had the highest number of fish species sampled from Kubanni Reservoir with the weight ranging from 4.70 to 173.60 (g); total length ranging from 6.50 to 21.50cm; Clarias gariepinus weight ranging from 2.90 to 414.70g; total length ranging from 7.40 to 38.80cm; Pollimyrus petricolus weight ranges from 2.80 to39.10g; total length from 6.30 to 20.20 cm; Schibe mystus weight ranging from 5.30 to 225.0g; total length 8.20 to 30.3cm; Lates niloticus weight ranges 17 to 310.0g; total length ranges between 12.3 and 29.5cm. The growth coefficient (b) obtained from the five species in Kubani reservoir for (Oreochromis niloticus (Linnaeus, 1758), Clarias gariepinus (Burchell, 1822), Pollimyrus petricolus (Daget, 1954), Schibe mystus (Linne, 1766) and Lates niloticus (Linnaeus, 1758) was 0.3283, 0.3364, 0.3205, 0.3191, and 0.3028, respectively. The b value across the species in both location differs significantly from 3 (P<0.05) indicating negative allometric growth for all the fish species. Therefore, there is strong positive correlation Length-Weight Relationship across the five major species in the location and growth pattern of the selected fish species showed negative allometric value in the location indicating the growth coefficient is (b < 3).
