Abstract

Globally, inland fisheries make a significant contribution to sustainable development across dimensions of food security, livelihoods, economic value and biodiversity. Nevertheless, aquaculture is generally considered to be environmentally unfriendly. As such, environmentally friendly approaches of increasing fish production such as fisheries enhancement receive increasing attention. Culturebased fisheries (CBF) are seen as a way forward for inland fisheries development in most Asian countries. Due to the extensive availability, reservoirs of Sri Lanka, which have been constructed in the past for irrigation, can secondarily be utilized for inland fisheries development. The reservoir fishery of Sri Lanka has been a relatively recent development during the second half of last century after the introduction of exotic cichlid species, Oreochromis mossambicus and O. niloticus. The trends in inland fish production until the 1990s suggested that under the socio-economic milieu that prevailed, for the management of reservoir fisheries, state sponsored monitoring procedures or centralized management systems was essential. Due to the concerted efforts to develop CBF in Sri Lankan reservoirs after 2000, through regular stocking of fingerlings of tilapia, Chinese carps and Indian carps, a significant development in the inland fisheries sector has been achieved. Recent attempts at stocking Macrobrachium rosenbergii postlarvae in inland reservoirs as part of CBF contributed to significant elevation of rural income. Also, ‘human capital’ in the rural institutions (i.e., famer organizations and fisheries societies) has a high potential to be mobilised for CBF development. Introduction of comanagement strategies for CBF is useful for its sustainability. CBF development in Sri Lankan reservoirs should essentially be a transdisciplinary approach, which would take into account the biological productivity favouring growth of stocked fish, institutional linkages for supporting different stages of the strategy, social attitudes for adopting CBF within the realm of participatory development, and market forces driving the entire process.
