Abstract/Summary

Understanding the potential of small water bodies (SWBs) will open greater opportunities in investment towards increased food and energy production. This study established the carrying capacity for fisheries development in SWBs in eight counties in Central and seven counties in Western Kenya. The carrying capacity of SWBs was calculated using socio-economic index (SI), trophic status index (TSI), and summaries of socio-economic and limnological data from 74 SWBs. The central region had a potential of 72,447 t in 37 sampled SWBs, whereas that of the western region had only 447 t in a similar number of sampled sites that forms part of the total national aquaculture potential. The higher potential in the central region is attributed to the relatively larger hydroelectric dams located in the area. To boost production in SWBs with low carrying capacities, restocking with native endemic fish species, which require limited or no supplementary feeding, is recommended. However, in SWBs, where depths reach 3.0 m or more, which optimises on intensive feeding and good water circulation, cage culture reared fish coupled with a strong local community association would be recommended. The indexing holistic approach herein forms an integrative management tool for fisheries production.
