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 ...
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 ...
Improving feed efficiency in fish using selective breeding: A review
Type: Journal Article
Improving feed efficiency (FE) is key to reducing production costs in aquaculture and to achieving sustainability for the aquaculture industry. Feed costs account for 30-70% of total production costs in aquaculture; much ...
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). ...
Genetic relationships among founders of a silver carp (Hypophthalmichthys molitrix) genetic improvement program in Bangladesh
Type: Journal Article
Silver carp (Hypophthalmichthys molitrix) is an important aquaculture species in Bangladesh and globally. Multiple introductions have been made of this exotic species to Bangladesh since 1969. Accordingly, the genetic ...
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 ...
Quantifying the genetic parameters of feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
Improving feed efficiency in fish is crucial at the economic, social and environmental levels with respect to developing a more sustainable aquaculture. The important contribution of genetic improvement to achieve this ...
