Gender-differentiated preferences regarding rohu carp (Labeo rohita) in Bangladesh: A case study
Type: Internal Report
The focus of this case study is the rohu carp genetic improvement program based in Bangladesh. The work forms part of the Sustainable Aquaculture Program of WorldFish and the CGIAR Research Program on Fish Agri-Food Systems ...
Growth performance of three strains of Nile tilapia (Oreochromis niloticus) on four different feeds in Western and Central Kenya
Type: Journal Article
The growth performance of three commercially available strains of Nile tilapia (Oreochromis niloticus) fed one of four different commercially available feeds during nursery and grow-out was assessed in Kenya. Each of the ...
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 ...
European Commission | TRUE-FISH R3.3: Improved protection of biodiversity, in relation to conservation of native species of tilapias in the EAC region. Annual narrative report: September 2021 to June 2022
Type: Donor Report
Tilapia aquaculture systems in EAC region are based on a handful of species, notably Oreochromis niloticus (Nile tilapia). However, there are other wild tilapia species and strains that could be potential candidate species ...
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 ...
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 ...
