Shrinking Lake Chad: Initialization of culture-based fisheries for improved livelihood in Nigeria

Abstract

Climate change and high water demand from agriculture have resulted in the shrinkage of numerous water bodies including the Lake Chad. The fisheries resources of the Lake Chad are near collapse causing a huge loss of livelihood. Culture-based fisheries (CBF) which is a form of extensive aquaculture where fish seeds are stocked in existing water bodies enabling them to feed on the naturally occurring organisms is presented as a plausible strategy for augmenting fish production. Standard management strategies and steps for the initialization of CBF are highlighted in the form of consultations and decisions which include: community consultation; selection of water bodies; decision on stocking, harvesting strategy and sharing formula. Optimal utilization of the numerous water bodies around the Lake Chad for CBF would lead to increased fish supplies at an affordable price to rural communities as well as provide an additional source of income and thereby improve means of livelihood.
