Life at retirement is a very critical period in the life of people. As a result it is expected that retirees, since they have more time to themselves, should be engaged in one activity or the other in order to earn extra income to supplement their pension. This study was conducted to ascertain if many retirees are engaged in fish farming in Delta state, Nigeria, considering the fact that fish is in high demand because of the nutritional value. Two hundred and thirty (230) respondents were selected for this study. Data were collected with the use of questionnaires and interview schedule. Most of the retirees were males, married and educated, with average household size of 5 persons. They had attended agricultural extension training sessions during their active service years. However, most of them were not engaged in fish farming after retirement. The decision of those who are engaged in fish farming was influenced by level of education, marital status, household size and extension training. Conversely, the decision of those who were not engaged in fish farming was informed by their age and gender. It was recommended that workers should be trained and encouraged to engage in fish farming after retirement, agricultural extension training programmes for workers (members of workers cooperative societies) should be sustained and workers need to be encouraged to engage in fish farming some years prior to their retirement.
