A review of aquaculture production and health management practices of farmed fish in Kenya
Type: Journal Article
This 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 ...
Fecundity, growth parameters and survival rate of three African catfish (Clarias gariepinus) strains under hatchery condition
Type: Journal Article
Three 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.
Estimates of phenotypic and genetic parameters for carcass traits in Nile Tilapia selected for fast growth in low-input conditions
Type: Other
Nile 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 ...
Heritability of cold tolerance in Nile tilapia, Oreochromis niloticus juveniles
Type: Journal Article
The inability of tilapia to tolerate low temperatures is of major economic concern as it reduces their growing season and leads to over winter mortality. In this study, cold tolerance of juvenile Nile tilapia, Oreochromis ...
Assessment of the impact of dissemination of genetically improved Abbassa Nile tilapia strain (GIANT-G9) versus commercial strains in some Egyptian governorates
Type: Journal Article
WorldFish 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 ...
Mycoflora and mycotoxins in finished fish feed and feed ingredients from smallholder farms in East Africa
Type: Journal Article
In 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 ...
Genetic and environmental factors affecting growth of Nile tilapia (Oreochromis niloticus) juveniles: Modelling spatial correlations between hapas
Type: Journal Article
The aim of this study was to quantify the environmental and genetic effects on early growth of Nile tilapia, Oreochromis niloticus.
Factors affecting early growth of Nile tilapia fry in hapa-in-pond environments
Type: Report
Hapas, 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 ...
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
Type: Journal Article
In 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 ...
Effects of rearing conditions on low temperature tolerance of Nile tilapia, Oreochromis niloticus, juveniles
Type: Conference Proceedings
This 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 ...
