The growth of aquaculture sector in Kenya has been anchored on farmed Nile tilapia Oreochromis niloticus. Different strains the species exist with unknown quality due to lack stock improvement programmes coupled by variations breeding and management practices different hatcheries. seeds supplied farmers have not exhibited good performance resilience changing climate. There is need validate fish...

In the United States, catfish are primarily farmed in earthen ponds, resulting an aquatic environment influenced both by management practices and natural ecological processes. Profiling pond water microbiota can be useful for understanding what conditions may lead to microbial communities associated with production issues could inform practices. The aim of this study was identify appropriate me...

A feeding trial was conducted towards optimization of feeding regimes for semi-intensive culture of Mozambique tilapia in earthen ponds in order to improve pond and effluent water quality, and reduce feeding cost. Fifty Mozambique tilapia fingerlings with an average weight of 17.8 ± 1.6 g were stocked in each of the 40 hapas. The experimental layout consisted of five feeding treatments of 20, 4...

In the effort to determine if hydrologic restoration in Knuthsen Meadow affects root abundance and soil moisture, we gathered preliminary data to determine the optimal experimental design and sample size necessary to detect a 25% increase in root biomass and soil moisture following restoration. We found high variability in root biomass, with upstream meadow reaches having substantially greater ...

There is a clear need to develop feed/fertilizer combinations that are appropriate for fish farming in Kenya and other parts of Africa. The strategy of using high-quality nutritionally complete feeds to produce high fish yields, frequently employed in developed countries, is often impossible or inappropriate in countries where high-quality feed ingredients are in short supply or are very expens...

Effect of cooking, fermentation, dehulling and the use of utensils on flavonoids (quercitin and pelargonidin) - antioxidants present in pearl millet (Pennisetum typhoideum) rabadi, along with proximate composition and sensory acceptability of the product were studied. Study revealed an increased ash and flavonoids and reduced crude fibre after cooking in all samples, while fermentation enhanced...
