Food insecurity remains one of the most visible dimensions of poverty. The increasing population amid competition for land and water resources means that the global demand for food will continue to increase. In Kenya, the ...
Studies on the development of low-cost and stable live food production technologies for tropical aquaculture: a case study of Rotifera (Family: Brachionidae)
(Nagasaki University's, 2017-09-20)
Live food resources e.g. rotifers, copepods, cladocerans and Artemia are critical
for successful fish larviculture. However, the hatchery production of these live foods
depends on the availability of high density microalgae, ...
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 ...
