Genetic improvement of Israeli blue (Jordan) tilapia, Oreochromis aureus (Steindachner), through selective breeding for harvest weight
Type: Journal Article
Genetic parameters and selection responses were obtained for harvest body weight of blue tilapia (Oreochromis aureus) from data collected over three generations in a selected population. A total of 18 194 records representing ...
Genetic variance for uniformity of harvest weight in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Competition for resources is common in aquaculture, which inflates the variability of fish body weight. Selective breeding is one of the effective approaches that may enable a reduction of size variability (or increase in ...
Breeding for robustness: Investigating the genotype-by-environment interaction and micro-environmental sensitivity of Genetically Improved Farmed Tilapia (Oreochromis niloticus)
Type: Journal Article
The objectives of this study were (i) to quantify the degree of G x E by assessing the growth performance of Genetically Improved Farmed Tilapia (GIFT) across three countries (Malaysia, India and China) and (ii) to quantify ...
Dissemination and evaluation of genetic improved tilapia species in Asia (DEGITA): final report (January 1998)
Type: Report
The major objectives of the DEGITA ( Project (Dissemination and Evaluation of Genetically Improved Tilapia Species in Asia) were: 1) to carry out genetic, socio economic and environmental evaluation of the improved tilapia ...
Genetic evaluation of growth and survival at 6 weeks old fry of Egyptian Nile Tilapia (Oreochromis niloticus) between improved Abbassa and commercial Manzala strains in a diallel crossing
Type: Journal Article
The main objectives of this study were to evaluate growth performance and estimate line crossing parameters of improved Abbassa tilapia strain and a commerciall Manzala strain within a complete diallel cross at 6 weeks old ...
Manual on genetic improvement of farmed tilapia (GIFT) research methodologies
Type: Manual
Gathering and recording of biological data vital to experiments in a genetic improvement program should be carried out with efficiency, precision and accuracy. This is important in order to avoid marking erroneous conclusion ...
Applied genetics of tilapias
Type: Working Paper
The present world production of tilapias is relatively low, despite their high potential for aquaculture. Most research efforts towards their husbandry have been aimed at solving the major problem in tilapia culture, ...
Genetic Improvement of Farmed Tilapias (GIFT) phase II (January 1993 to December 1997): plan of project activities - year 2 (January to December 1994)
Type: Report
The GIFT project is a major strategic research initiative in applied genetics and breeding in tropical aquaculture. The Nile tilapia (Oreochromis niloticus) was selected as a pilot species for the GIFT project because of ...
Tilapia genetic resources for aquaculture
Type: Conference Proceedings
Tilapia culture in Asia and other non African countries is practiced on a narrow genetic base. In contrast, African countries, many of which need assistance to develop their own aquaculture sectors, hold the global wealth ...
European Commission | TRUE-FISH R3.3: Improved protection of biodiversity, in relation to conservation of native species of tilapias in the EAC region. Annual narrative report: September 2021 to June 2022
Type: Donor Report
Tilapia aquaculture systems in EAC region are based on a handful of species, notably Oreochromis niloticus (Nile tilapia). However, there are other wild tilapia species and strains that could be potential candidate species ...
