This study aimed at identifying issues confronting fishermen within the Owabi reservoir, Ghana, West Africa using LEK. Data from twenty (20) fishermen were collected on fishing methods and techniques, fish species, and alternative livelihood using open and closed-ended questionnaires. From the study, fishers indicated nine species are mostly harvested from the dam, with most fish species declining in abundance. The status of fish species in the reservoir is affected negatively by climate change and waste disposal. As a result, most fisherfolks are engaged in alternative livelihoods to supplement returns from fishing activities. Fisherfolks engage in illegal fishing methods, though materials for illegal fishing methods are rarely available on the open market. To sustain the fisheries of the Reservoir, management should engage fisherfolks in community awareness programs on the impact of illegal fishing activities, as it will sustain the fisheries of the Reservoir.
