Preferences for rohu fish (L. rohita) traits of women and men from farming households in Bangladesh and India
Type: Journal Article
As selective breeding programs are time-consuming and expensive, it is critical that clients preferred traits are accurately identified. This is important to achieve value for money and adoption of selectively improved ...
Quantitative trait loci controlling swimming performance and their effect on growth in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Critical swimming speed (Ucrit) is an important measurement of swimming performance and a good indicator for cardio-respiratory health. It offers a new opportunity to select fish with better fitness. However, the genomic ...
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). ...
Performance of Oreochromis niloticus and Oreochromis andersonii in controlled laboratory conditions in Zambia
Type: Journal Article
In the present study, two hatchery strains of Oreochromis niloticus and two of O. andersonii sourced from different hatcheries in Zambia were subjected to the same feeding and management regimes in a controlled indoor tank ...
A review of access and benefit-sharing measures and literature in key aquaculture-producing countries
Type: Journal Article
Countries increasingly use access and benefit-sharing laws as a tool for the conservation and sustainable use of biological resources and associated traditional knowledge. These laws generally require the recipient of ...
On-farm performance of genetically-improved rohu (Labeo rohita) in Bangladesh
Type: Journal Article
Introduction: Rohu (Labeo rohita Hamilton) is a globally significant aquaculture species for which genetically improved strains are increasingly available. In 2020, a multiplier population, comprised of highly–ranked ...
Growth, yield and profitability of genetically improved farmed tilapia (GIFT) and non-GIFT strains in Bangladesh
Type: Journal Article
On-farm performance of the genetically improved farmed tilapia (GIFT) strain in monoculture and polyculture ponds in Bangladesh was assessed using a stratified random sample of 213 GIFT and 256 non-GIFT farmers. The GIFT ...
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 ...
Early selection to enhance genetic gain in a rohu (Labeo rohita) genetic improvement program
Type: Journal Article
Multiple-stage selection can, in certain circumstances, be adopted to enhance genetic gain in genetic improvement programs while avoiding the cost of assessing and maintaining all individuals for extended periods. The ...
