A review of aquaculture production and health management practices of farmed fish in Kenya
(2018)Type: Journal ArticleThis paper reviews aquaculture production systems and fish health management practices in Kenya in order to establish and document actions needed to monitor, mitigate and regulate effectively for future fish health problems ... -
Assessment of the impact of dissemination of genetically improved Abbassa Nile tilapia strain (GIANT-G9) versus commercial strains in some Egyptian governorates
(2019)Type: Journal ArticleWorldFish initiated a selective breeding program in Abbassa--Egypt to develop and produce the genetically improved Nile tilapia strain known as “Genetically Improved Abbassa Nile tilapia (GIANT)”, adopting the same technology ... -
Effects of rearing conditions on low temperature tolerance of Nile tilapia, Oreochromis niloticus, juveniles
(2004)Type: Conference ProceedingsThis paper summarizes the results of two experiments in which the effects of genotype, age, size, condition factor and diet (natural phytoplankton versus formulated protein pellets) on low-temperature tolerance of juvenile ... -
Estimates of phenotypic and genetic parameters for carcass traits in Nile Tilapia selected for fast growth in low-input conditions
(2005)Type: OtherNile tilapia is sold as either un-gutted or gutted whole carcasses, or as depending on geographical location. In whichever state the is sold, meat yield is an important consideration. Although carcass traits are of economic ... -
Factors affecting early growth of Nile tilapia fry in hapa-in-pond environments
(2005)Type: ReportHapas, usually suspended in fertilized ponds, have long been used for tilapia fry production (Santiago et al., 1985; Bhujel, 1997) and recently for fry rearing. In fish breeding programs, members of a full-sib family usually ... -
Fecundity, growth parameters and survival rate of three African catfish (Clarias gariepinus) strains under hatchery condition
(2017)Type: Journal ArticleThree strains of African catfish (Clarias gariepinus) from the Netherlands (Dutch), Indonesia and Kenya (Lake Victoria) were studied in hatchery conditions to compare their fecundity, growth performance and survival rates. -
Genetic analysis of Nile tilapia (Oreochromis niloticus) selection line reared in two input environments
(2009)Type: Journal ArticleAscertaining the appropriate selection environment for Nile tilapia (Oreochromis niloticus) in Africa is a critical issue. Two data sets derived from two selection lines originating from a common base population were ... -
Heritability estimates and response to selection for growth of Nile tilapia (Oreochromis niloticus) in low-input earthen ponds
(2006)Type: Journal ArticleThis study presents results of two generations of selection (G1 and G2) for growth of Nile tilapia. The selection environment consisted of earthen ponds which were fertilized daily with 50 kg dry matter (dm)/ha chicken ... -
Integration of mapping and socio-economic status of cage culture: Towards balancing lake-use and culture fisheries in Lake Victoria, Kenya
(2017)Type: Journal ArticleThe present study aimed to map the presence of cages and to profile the socio-economic characteristics of their owners in Lake Victoria Basin Kenya as baseline information to aid in the formation of policies to manage the ... -
Mycoflora and mycotoxins in finished fish feed and feed ingredients from smallholder farms in East Africa
(2017)Type: Journal ArticleIn this article, the authors provide a pioneer snapshot of the co-occurrence of aflatoxins, fumonisin and ochratoxin A, as well as other mycotoxins, in fish feed and ingredients from East Africa. A total of 52 samples of ... -
Phenotypic and genetic parameters for body measurements, reproductive traits and gut length of Nile tilapia (Oreochromis niloticus) selected for growth in low-input earthen ponds
(2007)Type: Journal ArticleIn this study we present estimates of phenotypic and genetic parameters for body size measurements, reproductive traits, and gut length for Nile tilapia (Oreochromis niloticus) selected for growth in fertilized earthen ... -
Production of genetically improved organic Nile tilapia
(2008)Type: Journal ArticleDemand for organic products for human consumption has been on the increase due to the belief that organic products are safer and healthier to the consumer and the environment. In developing countries, Nile tilapia (Oreochromis ... -
Selecting Nile tilapia (Oreochromis niloticus) for growth in low-input environments
(2007)Type: Book ChapterThis chapter presents the results from a selective breeding experiment with Nile tilapia in a low input pond environment. The environment was defined as low input as the pond only received chicken manure for fertilisation. ... -
Selection for growth of Nile tilapia (Oreochromis niloticus L.) in low-input environments
(2006)Type: ThesisThis thesis is a part of Wageningen University’s Interdisciplinary Research and Education Fund project entitled “Optimization of nutrient dynamics and fish for integrated agriculture- aquaculture systems” (INREF-POND). The ...
