A major quantitative trait locus affecting resistance to Tilapia lake virus in farmed Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Enhancing host resistance to infectious disease has received increasing attention in recent years as a major goal of farm animal breeding programs. Combining field data with genomic tools can provide opportunities to ...
Species composition in the Molobicus hybrid tilapia strain
Type: Journal Article
The “Molobicus” hybrid breeding programme was initiated to improve tilapia growth performance in brackish water. The base population was created by backcrossing F1 Oreochromis niloticus GIFT strains × feral O. mossambicus ...
Development and validation of an open access SNP array for 2 Nile Tilapia (Oreochromis Niloticus)
Type: Journal Article
Tilapia are amongst the most important farmed fish species worldwide, and are fundamental for the food security of many developing countries. Several genetically improved Nile tilapia (Oreochromis niloticus) strains exist, ...
Fish trait preferences: a review of existing knowledge and implications for breeding programmes
Type: Journal Article
Continued growth of the aquaculture sector will rely on the availability of fish with traits that respond to the needs and preferences of these users along the value chain. Such trait responsiveness requires that fish ...
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. ...
An investigation of links between metabolic rate and feed efficiency in European sea bass Dicentrarchus labrax
Type: Journal Article
Feed efficiency (FE) is the amount of body weight gain for a given feed intake. Improving FE through selective breeding is key for sustainable finfish aquaculture but its evaluation at individual level is technically ...
Agonistic behaviour and feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
The main hypothesis of the present study was that an aggressive and dominant fish would eat more feed and would be more efficient. To test this hypothesis, estimations of the relationships between agonistic behaviour, ...
Can individual feed conversion ratio at commercial size be predicted from juvenile performance in individually reared Nile tilapia Oreochromis niloticus?
Type: Journal Article
Feed conversion ratio (FCR), the ratio between feed intake and body weight gain, is of major interest for improving aquaculture sustainability through reduced feed costs and environmental impacts. Demonstrating whether FCR ...
Genome-wide association analysis of adaptation to oxygen stress in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Background: Tilapia is one of the most abundant species in aquaculture. Hypoxia is known to depress growth rate, but the genetic mechanism by which this occurs is unknown. In this study, two groups consisting of 3140 fish ...
A systematic literature review of the major factors causing yield gap by affecting growth, feed conversion ratio and survival in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Productivity among small‐ and medium‐scale tilapia farms varies considerably. The difference between the best performers and lower ones (yield gap), is affected by differences in growth rate and feed conversion ratio (FCR). ...
