Efficiency of pumpkin (Cucurbita pepo), sweet wormwood (Artemisia annua) and amaranth (Amaranthus dubius) in removing nutrients from a smallscale recirculating aquaponic system
(Springer International Publishing, 2019)In aquaponic systems, plants absorb dissolved nutrients from aquaculture wastewater for their growth. The removal of nutrients allows reuse of water and minimises wastewater discharge to the surrounding environment. This ... -
Blending fishwastes and chicken manure extract as low-cost and stable diet for mass culture of freshwater zooplankton, optimized for aquaculture
(IOP Publishing, 2019)This study investigated the feasibility of fishwastes and chicken manure extract (CME) as cheap diet for mass culture of freshwater zooplankton. CME and fishwastes as well as carbon source were used to make fishwaste ... -
The status of research on Lake Victoria fisheries: Historical and current data on fisheries and the lake environment
(AfricArXiv, 2019)Lake Victoria which is the second largest freshwater lake in the world supports a large population living around it through provision of food; fish and employment; both directly and indirectly. Due to its varied uses, ... -
Growth and Nutrient Removal Efficiency of Sweet Wormwood (Artemisia annua) in a Recirculating Aquaculture System for Nile Tilapia (Oreochromis niloticus)
(Multidisciplinary Digital Publishing Institute, 2019-05)The maintenance of optimal water quality for fish production is one of the major challenges in aquaculture. Aquaponic systems can improve the quality of water for fish by removing the undesirable wastes and in turn produce ... -
Growth response of rotifers on a bacterial-based diet made from fishwastes
(IOP Publishing, 2019-07)Fishwastes are potential low-cost diet sources for replacing microalgae, which is the popular diet for rotifers. Growth responses of rotifer were tested under different weights of the diet (i.e. 0.05, 0.1, 0.2 and 0.4 g/L), ... -

(AfricArXiv, 2019-09)Lake Victoria which is the second largest freshwater lake in the world supports a large population living around it through provision of food; fish and employment; both directly and indirectly. Due to its varied uses, human ... -
Culture Trials of Nile Perch Juveniles in Cages and Earthen Ponds
(2019-09)Fish were obtained from Asembo Bay, Dunga, Kendu Bay, Homa Bay and Mbita beaches around Lake Victoria using beach seines (< 10-mm mesh). Fish were sorted by size and stocked into hapa nets, each measuring 3 m× 3 m× 1 m, ... -
