The study examined the effects of researchers’ job characteristics on linkage activities in Nigeria due to the fact that many fish farmers have not been properly reached with technologies and the problem of poor food production has been attributed to the weak linkages existing between research, extension and fish farmers. A simple random sampling technique was used to select aquaculture researchers and their responses on involvement in linkage activities and level of job characteristics were elicited through a questionnaire. The result showed that researchers were satisfied with qualification for job (mean =4.50), opportunities to advance education and publish research (mean = 4.02 and 4.0). No significant relationship exist between linkage and researchers job characteristics (p<0.05). The paper concludes with the need to look into factors that will improve on the job characteristics and staff retention in the institute.
