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 ...
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 ...
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 ...
Comparing genomic signatures of selection between the Abbassa Strain and eight wild populations of Nile tilapia (Oreochromis niloticus) in Egypt
Type: Journal Article
Domestication to captive rearing conditions, along with targeted selective breeding have genetic consequences that vary from those in wild environments. Nile tilapia (Oreochromis niloticus) is one of the most translocated ...
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). ...
Pipette and paper: Combining molecular and genealogical methods to assess a Nile tilapia (Oreochromis niloticus) breeding program
Type: Journal Article
The paper compared molecular and paper records of pedigrees in a Nile tilapia breeding program, the Abbassa line in Egypt. It established a novel pipeline of checks and balances based on molecular data to correct erroneous ...
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 ...
Genetic parameters for resistance to Tilapia Lake Virus (TiLV) in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Tilapia Lake Virus (TiLV) is one of the primary disease concerns for tilapia farming, with mass mortality events and biosecurity restrictions threating aquaculture in several continents. Selective breeding for improved ...
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 ...
