A comparative study of the effects of pelleted and extruded feed on growth, financial revenue and nutrient loading of Nile tilapia (Oreochromis niloticus L.) cage culture in a lacustrine environment
Musa, Safina; Aura, Christopher Mulanda; Tomasson, Tumi; Sigurgeirsson, Ólafur; Thorarensen, Helgi (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-05)We compared the benefits of using extruded feed (EF), against pelleted feed (PF) to guide cage culture investments in Great Lakes. Three out of six cages in the same farm had fish that were fed EF and the other half, belonging to a different farm had fish that were fed PF. The diets were similar in crude protein, lipid and energy content. However, the fiber content in PF was 4 times higher than that ... -
Impacts of Nile tilapia cage culture on water and bottom sediment quality: The ability of an eutrophic lake to absorb and dilute perturbations
Musa, Safina; Aura, Christopher Mulanda; Tomasson, Tumi; Sigurgeirsson, Ólafur; Thorarensen, Helgi (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-07)Environmentally sustainable aquaculture depends on accurate understanding of the impacts of aquaculture-derived organic matter (AOM) and the ability of aquaculture systems to absorb and dilute perturbations. To this end, the present study assessed the impacts of AOM from cage culture of Nile tilapia on the ecology of Lake Victoria, Kenya, using fish cages near Anyanga Beach in Siaya County from ...
