EFFECT OF ELEVATED TEMPERATURE TREATMENT AND PAWPAW SEED POWDER ON PRODUCTION OF STERILE MONOSEX NILE TILAPIA
(University of Eldoret, 2019)Nile tilapia is the most widely cultured fish species in Kenya. The greatest problem with tilapia is its prolific breeding due to mixed sex, resulting in stunted growth of the fish. Therefore, there was a need to employ ... -
EFFECT OF IRON AMINO ACID CHELATE SUPPLEMENT IN FISH FEEDS ON GROWTH PERFOMANCE OF NILE TILAPIA (Oreochromis niloticus Linnaeus, 1758) AND SPINACH (Spinacia oleracea Linnaeus, 1552) IN AN AQUAPONIC SYSTEM
(University of Eldoret, 2018)Aquaponic is the combination of aquaculture and hydroponics. It is an environmentally friendly production system involving reuse of waste and nutrients in production of fish and vegetables. The research was conducted to ... -
EFFECTS OF HUMAN ACTIVITIES ON WATER QUALITY AND MACROINVERTEBRATES ALONG NYANGORES STREAM, MARA RIVER BASIN, KENYA
(University of Eldoret, 2013)The study investigated the effects of human activities on water quality and macroinvertebrates along the Nyangores stream in the upper catchment of Mara River Basin. Seven sampling sites were chosen to correspond to different ... -
EFFECTS OF STOCKING DENSITY AND SEASONALITY ON DIGENEAN TREMATODE AND MONOGENEAN INFECTIONS IN NILE TILAPIA (Oreochromis niloticus, Linnaeus 1758) REARED IN CAGES IN UHANYA BEACH IN LAKE VICTORIA, KENYA
(University of Eldoret, 2021)There exists a balance between, parasites, their fish hosts and the environment. However, when this balance is broken parasites spread rapidly in culture facilities inducing severe epizootics. This study was conducted from ... -
EFFECTS OF STOCKING DENSITY ON GROWTH, WATER QUALITY AND ECONOMIC PERFORMANCE OF MONOSEX NILE TILAPIA (Oreochromis niloticus) REARED IN AQUAPONICS SYSTEM
(University of Eldoret, 2021)Aquaponic systems integrate the culture of both plants and fish in recirculating aquaculture units. The nutrients derived from the fish are utilized by the plants for their growth in the system. The current study determined ... -
EFFECTS OF SUBSTITUTING COTTONSEED MEAL PROTEIN WITH Pro sopis juliflora SEED MEAL ON NILE TILAPIA GROWTH
(University of Eldoret, 2016)By the year 2020 there will be need for an additional 37 million tonnes of farmed fish per year, globally. However, limited availability and high cost of high quality feed stuffs hinders aquaculture development in Sub-Saharan ... -
