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, ...
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 ...
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). ...
Genomic Selection and Genome-wide Association Study for Feed-Efficiency Traits in a Farmed Nile Tilapia (Oreochromis niloticus) Population
Type: Journal Article
Nile tilapia is a key aquaculture species with one of the highest production volumes globally. Genetic improvement of feed efficiency via selective breeding is an important goal, and genomic selection may expedite this ...
Sex determination in the GIFT strain of tilapia is controlled by a locus in linkage group 23
Type: Journal Article
Tilapias (Family Cichlidae) are the second most important group of aquaculture species in the world. They have been the subject of much research on sex determination due to problems caused by early maturation in culture ...
