This study aimed at estimating the Aquaculture Carrying Capacity for tilapia (Oreochromis niloticus) on Cage Culture Using Beveridge Model in Oyan Lake. A total of 45 (fish, feed, sediment, and water) samples were collected from 3 different points labelled A, B, and C. The samples were analyzed to determine the Phosphorus content of the samples using different (AOAC) methods. Data on the Food conversion ratio of the fish, flushing rate, lake surface area, and depth obtained. The (TPP) obtained for fingerlings fishes were 23.8 x 106 metric tons, 71.2 x 106 metric tons and 44.3 x 106 metric tons, for juvenile fish were 86.39 x 106 metric tons, 63.67 x 106 metric tons and 60 x 106 metric ton, and for table size fish were 74.68 x 106 metric tons, 10.56 x 107 metric tons and 75.25 x 106 metric tons. According to water quality criteria for sustainable aquaculture, the capacity of the fish to be cultured on the lake should be 23.8 x 106 for fingerlings, 63.67 x 106 for juveniles, and 74.68 x 106 for table size fish. The phosphorus content of the water after aquaculture (Δp) sites varies, which shows that there is an alteration in the P- environment.
