Genetic parameters and correlated responses in female reproductive traits in the GIFT strain
Type: Journal Article
The aim of this study was to examine genetic variation in reproductive traits and to estimate correlated responses in such traits to selection for high growth rate in the GIFT strain of Nile tilapia (Oreochromis niloticus).
Genetic improvement programs for aquaculture species in developing countries: prospects and challenges
Type: Conference Paper
Aquaculture in developing countries is largely based on unimproved fish strains. There is ample evidence indicating the potential of genetic improvement programs and a range of selection methods may be used. Examples of ...
A systematic quantitative literature review of aquaculture genetic resource access and benefit sharing
Type: Journal Article
The Convention on Biological Diversity provides a framework for countries to implement laws regulating the access, use and exchange of genetic resources, including how users and providers share the benefits from their use. ...
Genetic improvement, support to aquaculture value chains and promotion of fish in foods systems in the Southern African Development Community (SADC)
Type: Presentation
WorldFish Genetics Workshop 2022- presentation on genetic improvement, support to aquaculture value chains and promotion of fish in foods systems in the Southern African Development Community (SADC)
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 ...
Towards policies for conservation and sustainable use of aquatic genetic resources
Type: Conference Proceedings
Genetic stock identification is increasingly needed for fisheries management. Genetic technologies are being developed to increase food production from aquaculture and to document and evaluate aquatic species, subspecies ...
Individual growth monitoring of European sea bass larvae by image analysis and microsatellite genotyping
Type: Journal Article
The aims of the present study were to develop non-lethal methods to identify individual fish larvae and post-larvae before tagging and accurately follow their growth characteristics. European sea bass (Dicentrarchus labrax) ...
Exploitation and conservation of fish genetic resources in Africa: issues and priorities for aquaculture development and research
Type: Journal Article
Africa harbours a rich biological diversity of native fish resources. Recognition of the potential to use these resources to make significant contributions towards improving African food security through aquaculture has ...
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 ...
