Pipette and paper: Combining molecular and genealogical methods to assess a Nile tilapia (Oreochromis niloticus) breeding program
Type: Journal Article
The paper compared molecular and paper records of pedigrees in a Nile tilapia breeding program, the Abbassa line in Egypt. It established a novel pipeline of checks and balances based on molecular data to correct erroneous ...
Seinability of four strains of Nile tilapia, Oreochromis niloticus, in Chinese ponds
Type: Journal Article
The objective of the current experiment was to examine seinability of four strains of Nile tilapia, O. niloticus, GIFT and Egypt 92, Egypt 88 and Sudan 78. The latter two are normally utilized in China.
Prátika Jestaun Di’ak Liu ba Produsaun Fini Ikan Tipaia Monoseksu: Matadalan ilustrada (Better management practices for monosex tilapia seed production: An illustrated guide)
Type: Manual
The booklet explains the better management practices (BMP) for producing high-quality genetically improved farmed tilapia (GIFT) monosex seed. These simple and low-cost methods have been tested and proven over five years ...
Quantifying the genetic parameters of feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
Improving feed efficiency in fish is crucial at the economic, social and environmental levels with respect to developing a more sustainable aquaculture. The important contribution of genetic improvement to achieve this ...
Risk analysis in aquaculture: A step-by-step introduction with worked examples
Type: Manual
This publication is based on materials covered and outputs generated during the Workshop on Risk Assessment Methodologies and Tools for Aquaculture in Sub-Saharan Africa, which was jointly held by WorldFish and FAO in ...
Flesh characteristics: estimation of genetic parameters and correlated responses to selection for growth rate in the GIFT strain
Type: Journal Article
Genetically improved farmed tilapia (GIFT) has undergone ten generations of selection for harvest body weight in Malaysia, but there have been no reports on genetic parameters for flesh characteristics for this strain. In ...
Applied genetics of tilapias
Type: Report
This paper reviews the successes and failures of genetic experiments on tilapias and points to various characteristics of tilapias, which require improvement for increased yields.
Genetic improvement of farmed tilapias: composition and genetic parameters of a synthetic base population of Oreochromis niloticus for selective breeding
Type: Journal Article
The present study is based on data recorded from fish of the third generation of the GIFT project (Genetic Improvement of Farmed Tilapias). The objective of the study was to compose a synthetic base population of Nile ...
Heritability estimates and response to selection for growth of Nile tilapia (Oreochromis niloticus) in low-input earthen ponds
Type: Journal Article
This 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 ...
Genetic and non-genetic indirect effects for harvest weight in the GIFT strain of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
The main objective of this study was to quantify the heritable variation for growth rate of GIFT, and the contribution of IGEs to this heritable variation. Here we describe the experiment conducted for this purpose, and ...
