Growth, Survival and Nutrient Utilization of Nile Tilapia (Oreochromis niloticus) using Cyanophyceae (Arthrospira fusiformis) as Replacement of Fishmeal Based Diets
(International Journal of Science and Research (IJSR), 2014-08)
Suitability of using cynaophyceae (Arthrospira fusiformis) to replace fishmeal (Caridina nilotica) as a main protein source in the diet of Nile tilapia (Oreochromis niloticus) was investigated at a ratios of: 25%, 50%, 75% ...
Comparative performance of invasive alien Eichhornia crassipes and native Ludwigia stolonifera under non-limiting nutrient conditions in Lake Naivasha, Kenya
(Hydrobiologia, 2010-09)
The ability of Ludwigia stolonifera to thrive in the presence of Eichhornia crassipes was
investigated in Lake Naivasha, Kenya. L. stolonifera (indigenous) and E. crassipes (invasive alien) were grown in outdoor experimental ...

Competition between Lemna minuta and Lemna minor at different nutrient concentrations
(Plant Biology and Nature Management (APNA) Elsevier, 2011-02)
We investigated the differential responses of invasive alien Lemna minuta and native Lemna minor to
nutrient loading as well as the mechanism of competition between the species. The role of nutrients,
species identity, ...
