Threatened cyprinid species in Asia
Type: Book Chapter
Despite the considerable potential for continued growth in cyprinid aquaculture production in Asia, there are increasing concerns about the status of native cyprinids especially those that are important to aquaculture in ...
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 ...
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 ...
Ex-situ conservation of the germplasm of aquatic organisms
Type: Journal Article
This paper summarizes some of the major issues relating to ex-situ conservation of the germplasm of aquatic organisms and gives examples of some current activities and future possibilities.
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 ...
A comparison of communal and separate rearing of families in selective breeding of common carp (Cyprinus carpio): Estimation of genetic parameters
Type: Journal Article
The objective of this study was to investigate ways of improving the selective breeding program for growth related traits in common carp in Vietnam. A base population was established from six carp stocks following a single ...
Importance and implementation of simple and advance selective breeding programs for aquaculture species in developing countries
Type: Conference Paper
Aquaculture is predicted to play a major and ever increasing role in meeting human needs for protein. In terrestrial animal and plant species genetic improvement programs have made a substantial contribution to productivity ...
Accounting for genotype by environment interaction in economic appraisal of genetic improvement programs in common carp Cyprinus carpio
Type: Journal Article
In this study we examine effects of genotype by environment (G×E) interaction due to re-ranking and scaling effects on economic benefit (EB) and benefit to cost ratio (BCR) from a genetic improvement program in common carp ...
Donor-oyster derived heritability estimates and the effect of genotype X environment interaction on the production of pearl quality traits in the silver-lip pearl oyster, Pinctada maxima
Type: Journal Article
The aim of this study was to estimate donor-oyster derived heritability and genetic correlations for pearl quality traits in the silver-lipped pearl oyster, P. maxima; namely pearl size, colour, lustre, shape and complexion. ...
