Indirect genetic effects and inbreeding: Consequences of BLUP selection for socially affected traits on rate of inbreeding
Type: Journal Article
Social interactions often occur among living organisms, including aquatic animals. There is empirical evidence showing that social interactions may genetically affect phenotypes of individuals and their group mates. In ...
The Network of Tropical Aquaculture Scientists (NTAS) : past, present and future
Type: Journal Article
This article reviews the past, present and future activities of the Network of Tropical Aquaculture Scientists (NTAS), an information network for individual scientists working on tropical aquaculture, especially on genetics, ...
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).
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 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 ...
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 ...
Genetic diversity of Nile tilapia (Oreochromis niloticus) throughout West Africa
Type: Journal Article
Nile tilapia (Oreochromis niloticus) is a globally significant aquaculture species rapidly gaining status as a farmed commodity. In West Africa, wild Nile tilapia genetic resources are abundant yet knowledge of fine-scale ...
Maximum likelihood parentage assignment using quantitative genotypes
Type: Journal Article
The cost of parentage assignment precludes its application in many selective breeding programs and molecular ecology studies, and/or limits the circumstances or number of individuals to which it is applied. Pooling samples ...
