Effects of pure and crude papain on the utilization and digestibility of diets containing hydrolysed feather meal by Nile tilapia (Oreochromis niloticus L.)
(KENYA MARINE AND FISHERIES RESEARCH INSTITUTE, 2014)This study was conducted to evaluate the effects of pure and crude papain on the digestibility and utilization of diets containing hydrolysed feather meal (HFM) by Nile tilapia (Oreochromis niloticus L.) under indoor and ... -
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 ... -

(Aquaculture International, 2019-08-28)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 ... -
Entomophagus Response of Indigenous Chicken to Diets Enriched with German Cockroach (Blattela germanica) Meal in Kenya
(2023-05-16)Feeding accounts for 65-70% of cost production in a chicken enterprise. Fishmeal has primarily been used as a source of protein in chicken feed owing to its excellent nutritional value. However, due to its unstable supply ... -
Factors Affecting Productivity and Profitability of Cage-Fish Farming in Siaya County, Kenya
(KALRO, 2022)Aquaculture is regarded as a critical rural development and livelihood strategy due to its vital role in livelihoods and the economy at large. However, declining capture fisheries from Lake Victoria and low pond productivity ... -
Factors influencing farmed fish traders’ intention to use improved fish post-harvest technologies in Kenya: application of technology acceptance model
(The Korean Society of Fisheries and Aquatic Science, 2023)Improved fish post-harvest technologies (IFPT) have been promoted as more efficient methods of fish processing, preservation, and value addition than the traditional methods prevalent in developing countries. The adoption ... -
Fish and fish products consumption behaviours and attitudes of farmers in western Kenya.
(ResearchGate, 2022)Fish and fish products contain high-quality protein of animal origin with essential bioavailable micronutrients such as iron, zinc, vitamins and omega-3 fatty acids. Although fish contribute to food and nutrition security, ... -
Fish feeds and feed management practices in the Kenyan aquaculture sector: Challenges and opportunities
(Michigan State University Press, 2021)Feeds and feed management practices are key to the development of the aquaculture sector. To achieve high levels of aquaculture production, fish farmers need nutritionally adequate and cost-effective feeds, which are ... -
FISH-RESTOCKING OF LAKES IN KENYA: SHOULD SOLEMNLY BE AN ENVIRONMENTAL ISSUE
(Nova Science Publishers, Inc., 2012)The self-described “social-ecologist”, Peter Drucker, said that what gets measured gets managed; a statement that could have welcomed political and social concepts into environmental matters. A case in point is the fish ... -
Genetic differentiation of Artemia franciscana (Kellogg, 1906) in Kenyan coastal saltworks
(Gent University, Belgium, 2013)The nature of genetic divergence between the Artemia population native to San Francisco Bay, (SFB) USA and those from the introductions of SFB material in the Kenyan coast (Fundisha and Kensalt) 2 decades ago were ... -
Genetic differentiation of Artemia franciscana (Kellogg, 1906) in Kenyan coastal saltworks
(Kenya Marine and Fisheries Research Institute, Kegati Aquaculture Research Station, 2014)The nature of genetic divergence between the Artemia population native to San Francisco Bay, (SFB) USA and those from the introductions of SFB material in the Kenyan coast two decades ago were investigated using the ... -
Growth and Nutrient Removal Efficiency of Sweet Wormwood (Artemisia annua) in a Recirculating Aquaculture System for Nile Tilapia (Oreochromis niloticus)
(Multidisciplinary Digital Publishing Institute, 2019-05)The maintenance of optimal water quality for fish production is one of the major challenges in aquaculture. Aquaponic systems can improve the quality of water for fish by removing the undesirable wastes and in turn produce ... -
Growth Performance of African Catfish (Clarias Gariepinus) Fed on Diets Containing Black Soldier Fly (Hermetia Illucens) Larvae Under Aquaponic System
(AQUAST910, 2022)Cost of fish production can be reduced by replacement of high-priced fishmeal (FM) with insects sourced ingredients. Four months feed experiment was conducted at a fish farm in Baringo County, Kenya to investigate effects ... -
Growth response of rotifers on a bacterial-based diet made from fishwastes
(IOP Publishing, 2019-07)Fishwastes are potential low-cost diet sources for replacing microalgae, which is the popular diet for rotifers. Growth responses of rotifer were tested under different weights of the diet (i.e. 0.05, 0.1, 0.2 and 0.4 g/L), ... -
