A review on the status of some major fish species in Lake Victoria and possible conservation strategies
(Lakes & Reservoirs: Science, Policy and Management for Sustainable Use., 2020-01-09)Lake Victoria, the second largest freshwater lake in the world, supports an enormous flora and fauna biomass, with a large human population around the Lake. The lake is a source of food (fish), water for domestic use and ... -
Earthworm, Eisenia fetida, bedding meal as potential cheap fishmeal replacement ingredient for semi-intensive farming of Nile Tilapia, Oreochromis niloticus
(Aquaculture Research, 2020-02-11)The study amalgamated earthworm and agro-industrial wastes through vermicomposting and then evaluated the potential of the bedding (mixture of Eisenia fetida and vermicompost) to replace fishmeal in semi-intensive farming ... -
Dietary Value of Waste-Fed Rotifer Brachionus rotundiformis on the Larval Rearing of Japanese Whiting Sillago japonica
(E3S Web of Conferences, 2020-02-12)Abstract. Live food resources are useful for larval fish rearing. However, production of sufficient live food resources is expensive. This study employed a cost-effective rotifer culture technique using fish waste diet ... -
Effects of aerated and non-aerated biofilters on effluent water treatment from a small-scale recirculating aquaculture system for Nile tilapia (Oreochromis niloticus L.)
(Sciendo, 2020-04-21)Most recirculation aquaculture systems (RAS) use aerated biofilters to maintain suitable water quality for fish production. However, application of non-aerated biofilters may provide opportunities to lower aeration costs, ... -
Status of fish health management and biosecurity measures in fish farms, cages and hatcheries in western Kenya.
(2021)Aquaculture is one of the critical sectors contributing to food and nutrition security, income and employment opportunities to millions of people and is currently the fastest growing food-producing sector globally. With ... -
Socio-economic Implications of Imported Frozen Tilapia on the Local fish Production and Value Chain Linkages: Case of Kisumu County, Kenya
(ScienceOpen, 2021)The amount of frozen tilapia import from China has increased over the past five years to the current 20,000 tons per year. The imports have assisted in bridging the fish production deficit in the country. This study was ... -
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 ... -
Selective breeding of Nile tilapia, Oreochromis niloticus: A strategy for increased genetic diversity and sustainable development of aquaculture in Kenya
(Taylor & Francis, 2021)The aquaculture subsector is important in Kenya for food and nutritional security. The rapid growth of the subsector is evident especially in the widespread culture of Nile tilapia (Oreochromis niloticus); however, the ... -
Aqua-Feed Wastes: Impact on Natural Systems and Practical Mitigations—A Review
(Journal of Agricultural Science, 2021)Dietary composition of aquaculture feeds (aquafeeds) determines the quality of wastes from aquaculture production systems. These wastes, which are derived mainly from nitrogenous and phosphorus compounds subsequently ... -
Periphyton Technology Enhances Growth Performance and Delays Prolific Breeding of Nile Tilapia, Oreochromis niloticus (Linnaeus, 1758), Juveniles
(Research Gate, 2021)This study evaluated the effect of periphyton technology (PPT) on the growth performance and breeding schedule of Oreochromis niloticus (Linnaeus, 1758) juveniles. Six ponds, each measuring 81 m2 were used for the study. ... -
Aquatic Ecosystem Health & Management
(Michigan State University Press, 2021)Capture fisheries and aquaculture have remained important sources of food, nutrition, income and livelihoods to millions globally, with annual per capita consumption of fish in developing countries having increased from ... -
Comparison of net fish yields in pond cultured Nile tilapia (Oreochromis niloticus L.) fed on peanut-based meals as alternatives to dietary fishmeal
(International Journal of Fisheries and Aquatic Studies, 2021)Although net yield directly relates to actual production at harvest, feeding trials aimed at replacing dietary fishmeal in cultured fish have largely ignored the performance indicator. A 16-week experiment aimed at ... -
