Fisheries and tourism potentials of Agbokim waterfalls, Nigeria

Human activities in natural environments are among the most important recreational needs. Monthly studies of tourism characteristics was conducted during wet and dry seasons, over a two year period in the three landscapes along the 6817.7m length of Agbokim waterfalls by using a close-ended pre-coded survey instrument. Through MANOVA analysis of the 1780 respondents, we found strong positive association between peoples visits to the recreational areas and the type of landscape in which the respondents felt happy. People who felt happier in landscape dominated by waterfalls, visit the middle reaches of the river for outdoor recreation more often, while people who feel happy in landscapes dominated by slow water current with an extensive wide area and floodplains, visit downstream reaches of the waterfalls more often. Activities performed more often along downstream reaches include fishing, bathing/swimming, boating and hunting while more frequent activities in the middle reaches (waterfalls) include taking photographs, picnics, enjoying nature, outing with family and friends, looking at view, resting and relaxing
