Effect of Replacing Fish Meal by Soybean-Blood Meal Mixture on Performance of Tilapia (Oreochromis Niloticus)
(THE INTERNATIONAL JOURNAL OF SCIENCE & TECHNOLEDGE, 2018)Commercial fish feeds are highly expensive and unaffordable to majority of fish famers, usually fish meal which is scarce and expensive is used in compounding fish feeds. A fourteen-week study was done to determine growth ... -
A review of the populations of tilapiine species in lakes Victoria and Naivasha, East Africa
(African Journal of Aquatic Science, 2021)This paper discusses the catch trends, population attributes and biological characteristics of tilapiine species that are both native and that have been introduced into Lake Victoria and Lake Naivasha. Predation by Lates ... -
Some aspects of reproduction and feeding habits of Nile tilapia (Oreochromis niloticus) in three dams in Uasin Gishu County, Kenya
(Lakes & Reserv, 2019)Knowledge of the fisheries status of dams within Uasin Gishu County was needed prior to the government's plan to introduce fish and fisheries in the area. The dams were constructed in the 1950s and stocked with tilapia ... -
Assessment of Duckweed Supplement Diet to Fishmeal on the Growth Performance of Oreochromis niloticus Fingerlings
(AER Journal, 2019)Oreochromis niloticus is the most cultured fish in tropical freshwater aquaculture systems and second most cultured fish after carps in the world. In Kenya, Oreochromis niloticus has potential in eradicating hunger and ... -
A review on the status of some major fish species in Lake Victoria and possible conservation strategies
(Lakes & Reservoirs, 2019)Lake Victoria, the second largest freshwater lake in the world, supports an enor mous flora and fauna biomass, with a large human population around the Lake. The lake is a source of food (fish), water for domestic use ... -
