(Kenya Marine and Fisheries Research Institute, National Aquaculture Research Development and Training Center,, 2014)Nile tilapia (Oreochromis niloticus) fingerlings were reared in earthen ponds at three different feeding frequencies; twice daily, twice after 1 day, and twice after 2 days for a period of 7 months. Three hundred and ... -
Haematological response of African Catfish (Clarias gariepinus Burchell 1822) fingerlings exposed to different concentrations of tobacco (Nicotiana tobaccum) leaf dust
(Hindawi, 2013)The present study set out to investigate the haematological effects of tobacco leaf dust on African catfish, Clarias gariepinus, fingerlings, with a mean weight of 3.01 ± 1.25 g using “static renewal bioassay system” ... -
Impacts of Covid-19 Pandemic and Adaptive Strategies to Build Resilience in the Kenyan Aquaculture Sector
(ScienceOpen, 2022)This study examines the impacts of the Covid-19 pandemic and adaptive strategies to build resilience among stakeholders and actors in the aquaculture value chain in Kenya. Prior to the pandemic, Kenya's aquaculture sector ... -
The impacts of introduced species on lake ecosystems: A case of Lakes Victoria and Naivasha, Kenya.
(2019)Fish and other aquatic organisms have been introduced into new environments for various reasons. Provision of sports fishery, supplemental to stocks, to fill empty niches, control weeds, and disease vectors and even create ... -
In vitro assessment of ruminal fermentation characteristics of tropical browse mixtures supplemented with yeast
(Blackwell Publishing Ltd, 2012-03-01)An in vitro ruminal gas production study was conducted to assess the effect of yeast supplementation on rumen fermentation of tanniniferous tropical browse mixtures prepared by mixing Berchemia discolor with Acacia ... -
In vitro organic matter disappearance of tanniferous browse using rumen liquid from goats ingesting grass versus browse
(Taylor & Francis, 2013-12-01)In vitro organic matter disappearance (IVOMD) of African browse species often indicates artificially low nutritive value due to the presence of condensed tannins (CT). Diet of the rumen liquor donor may change this if ... -
