Abbassa Tilapia breeding program
Type: Presentation
WorldFish Genetics Workshop 2022 - ppt presentation about the Tilapia breeding program in Abbassa.
Genetic parameters for survival during the grow-out period in the GIFT strain of Nile tilapia (Oreochromis niloticus) and correlated response to selection for harvest weight
Type: Journal Article
The aims of this study were the estimation of genetic parameters for survival rate from tagging until harvest and the evaluation of the correlated response in survival rate to selection for harvest weight in the genetically ...
Genetically improved farmed tilapia (GIFT) selective breeding program
Type: Presentation
WorldFish Genetics Workshop 2022 - ppt presentation about the history, present and future of the GIFT tilapia selective breeding program.
Photographic image analysis for morphometric studies of tilapia
Type: Journal Article
Biologists have long employed morphometry as a tool in identification, grouping of populations and stock identification of fish. For tilapias, studies have been made on the variability of morphomeric characters in Egyptian ...
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 ...
Closing the yield gap: improving production efficiency in smallholder farms of Nile tilapia through selective breeding
Type: Thesis
The aim of this thesis was to optimise the breeding program of Nile tilapia for a smallholder production system, thereby contributing to closing the yield gap. From Chapter 2 to 4, we generated information that can be used ...
Electrophoretic evidence for extensive hybrid gene introgression into commercial Oreochromis niloticus (L.) stocks in the Philippines
Type: Journal Article
The usefulness of isozyme and protein markers in identifying tilapia species and their hybrids is demonstrated Genetic characterization of Oreochromis niloticus populations from commercial farms, experimental stations, and ...
Estimation of genetic change in the GIFT strain by comparing contemporary progeny produced by males born in 1991 or 2003
Type: Conference Paper
During the development of the GIFT (Genetically Improved Farmed Tilapia) strain in Philippines sperm was frozen from a sample of males from founder stocks and subsequent generations. In this paper a comparison of progeny ...
Genetic Improvement Programs Advisory Programs in Africa and Asia
Type: Presentation
WorldFish Genetics Workshop 2022 - Presentation on the Genetic Improvement Advisory Programs in Africa and Asia.
Genotype by environment interaction and genetic heterogeneity of environmental variance of body weight at harvest in genetically improved farmed tilapia (Oreochromis niloticus) reared in 3 different countries
Type: Journal Article
Establishing breeding programs that improve farmed fish performance across multiple environments is crucial in a globalized aquaculture market. The main objectives of the current study were to assess the growth performance ...
