6 Enhancing Rural Farmer Income through Fish Production127agriculture. CBF also is an environmentally friendly activity, as apart from stocking,there is little or no manipulation of the environment.In the wake of increasing constraints on water resources use of existing smallwater bodies, CBF is gradually accepted as a significant strategy for increasing fishproduction, particularly benefitting rural communities, to augment their nutritionstatus, income generation and social well being. The environmentally friendlynature of CBF activities and the minimal capital investments needed are majoradvantages to further its adoption by rural communities. It is in the above-mentionedcontext that those developing nations that have begun to adopt this practiceas a means of increasing fish production are witnessing an increasing degree ofadoption of CBF by rural communities, and needless to say, a gradually evolvingsuccess story in aquaculture.Acknowledgments We acknowledge the cooperation of IISD and NACA for preparing thischapter. Mr. M.G. Kularatne assisted in the preparation of Fig. 6.2 of this chapter and providedunpublished information on socioeconomics of CBF in Sri Lanka. We are thankful to Dr. D.E.M.Weerakoon, Director General of National Aquaculture Development Authority of Sri Lanka(NAQDA), for providing data on the operation of community-based mini-nurseries. Ms. J.M.Asoka provided the CBF data that she has collected for her postgraduate research.ReferencesAmarasinghe, U.S. 1992. Recent trends in the inland fishery of Sri Lanka, 84–105.
