(AJFAND, 2013-09-26)Integrated livestock-fish culture approach envisages the integration of fish farming with cattle, sheep, goats, poultry, pigs or rabbit husbandry in a design allowing wastes from one system to be used as inputs in another ... -
Carcass Characteristic of Indigenous Chicken Fed on Diets Containing German Cockroach (Blattela germanica) Meal in Kenya
(African Journal of Education, Science and Technology, 2023-09-11)Edible insects are available for use in insect-based-feed, however there is limited information on carcass characteristics and sensory tests of chicken fed on German cockroaches (Blattela germanica). This study assessed ... -
The challenges of management: Recent experiences in implementing fisheries co‐management in Lake Victoria, Kenya
(2015-09)his study examined the efficacy of community‐level fishery co‐management organizations called Beach Management Units (BMUs) along the Kenyan shores of Lake Victoria. BMUs were established to enhance sustainable Lake Victoria ... -
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 ... -
Complete mitochondrial genome of the freshwater monogonont rotifer Brachionus angularis (Rotifera, Brachionidae)
