FISH PRODUCTION ESTIMATES FOR GBEDIKERE LAKE, BASSA, KOGI STATE, NIGERIA
Annual estimates of the fish caught by local fishermen in randomly selected fishing villages adjacent to Gbedikere Lake were determined using Catch Assessment (CAS). The studies were carried out within two seasons of low water (February) and high water (September) periods between 2006 to 2008. Annua...

| description | Annual estimates of the fish caught by local fishermen in randomly selected fishing villages adjacent to Gbedikere Lake were determined using Catch Assessment (CAS). The studies were carried out within two seasons of low water (February) and high water (September) periods between 2006 to 2008. Annual fish catch varied from 537.4 mts to 576.9 mts at high water. Mean catch per boat ranged from 7.40 kg to 10.60 kg among the landing sites. A total of 12 fish species were identified belonging to ten families. The catches were dominated by the cichlids with Orechromis niloticus dominating the overall catch compositions. Production estimate was compared with the catches obtained through experimental gill-net sampling and potential fish yield estimates using Ryder’s Morpho - Edaphic Index (MEI) as modified by Henderson and Welcomme (1974). Contributions of the gears in use were also done with cast nets ranking above others (29%), followed by the set net (25%), hook and lines (16.6%), traps (16.6%), clap net (8.3%). Management measures were suggested. |
