Genetic correlations between harvest weight and secondary traits in a silver carp (Hypophthalmichthys molitrix) genetic improvement program
(2022)Type: Journal ArticleIn 2017, the base population of a family-based silver carp (Hypophthalmichthys molitrix) genetic improvement program was spawned in Bangladesh. This program aims to improve the growth rate of silver carp under polyculture ... -
Genetic parameters for black spot disease (diplopstomiasis) caused by Uvulifer sp. infection in Nile tilapia (Oreochromis niloticus L.)
(2021)Type: Journal ArticleBlack spot disease (diplopstomiasis), an external melanized host inflammatory response caused by a number of digenetic trematode parasites, results in slow growth, deformities and increased mortality among many freshwater ... -
Genetic parameters for resistance to Tilapia Lake Virus (TiLV) in Nile tilapia (Oreochromis niloticus)
(2020)Type: Journal ArticleTilapia 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 ... -
Genetic relationships among founders of a silver carp (Hypophthalmichthys molitrix) genetic improvement program in Bangladesh
Type: Journal ArticleSilver 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 ... -
Genetic variation in wild populations and farmed stocks of Nile tilapia (Oreochromis niloticus) in Madagascar
(2019)Type: Journal ArticleFour farmed stocks and four wild populations of Nile tilapia (Oreochromis niloticus), which was first introduced to Madagascar sixty years ago, were assayed for genetic variation at nine microsatellite loci to determine ... -
Genome-wide association analysis of adaptation to oxygen stress in Nile tilapia (Oreochromis niloticus)
(2021)Type: Journal ArticleBackground: 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 ... -
Genomic Selection and Genome-wide Association Study for Feed-Efficiency Traits in a Farmed Nile Tilapia (Oreochromis niloticus) Population
(2021)Type: Journal ArticleNile 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 ... -
Genomics in marine monitoring: New opportunities for assessing marine health status
(2013)Type: Journal ArticleThis viewpoint paper explores the potential of genomics technology to provide accurate, rapid, and cost efficient observations of the marine environment. The use of such approaches in next generation marine monitoring ... -
Genotype by environment interaction and genetic heterogeneity of environmental variance of body weight at harvest in genetically improved farmed tilapia (Oreochromis niloticus) reared in 3 different countries
(2016)Type: Journal ArticleEstablishing breeding programs that improve farmed fish performance across multiple environments is crucial in a globalized aquaculture market. The main objectives of the current study were to assess the growth performance ... -
Genotype by environment interaction between aerated and non-aerated ponds and the impact of aeration on genetic parameters in Nile tilapia (Oreochromis niloticus)
(2020)Type: Journal ArticleA major problem in smallholder Nile tilapia (Oreochromis niloticus) farms is that the achieved production is much lower than under optimal management. One of the main environmental factors contributing to lower production ... -
Genotype-by-culture-system interaction in catla and silver carp: Monoculture and biculture
(2022)Type: Journal ArticleCatla (Catla catla) and silver carp (Hypophthalmichthys molitrix) are globally significant aquaculture species, primarily grown in polyculture. The objectives of the current study were to i) quantify genetic differences ... -
Growth performance of three strains of Nile tilapia (Oreochromis niloticus) on four different feeds in Western and Central Kenya
(2021)Type: Journal ArticleThe 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 ... -
Growth, yield and profitability of genetically improved farmed tilapia (GIFT) and non-GIFT strains in Bangladesh
(2021)Type: Journal ArticleOn-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 ... -
Heritable variation in swimming performance in Nile tilapia (Oreochromis niloticus) and negative genetic correlations with growth and harvest weight
Type: Journal ArticleNile tilapia is predominantly produced in smallholder ponds without aeration. We hypothesize that Nile tilapia with high oxygen uptake efficiency (O2UE) may perform better under these conditions than Nile tilapia with low ... -
A high-quality chromosome-level genome assembly of rohu carp, Labeo rohita, and its utilization in SNP-based exploration of gene flow and sex determination
(2023)Type: Journal ArticleLabeo rohita (rohu) is a carp important to aquaculture in South Asia, with a production volume close to Atlantic salmon. While genetic improvements to rohu are ongoing, the genomic methods commonly used in other aquaculture ... -
IFAD_Improving the Technological Foundations for Sustainable Aquaculture_Interim Progress Report _Year 3_Sep 2018 - Sep 2019
Type: Donor ReportThis IFAD/WorldFish project builds on WorldFish knowledge and experiences on fish genetic improvement, and dissemination activities across Asia and Africa, including earlier projects funded by IFAD/EC, providing a combination ... -
An investigation of links between metabolic rate and feed efficiency in European sea bass Dicentrarchus labrax
(2021)Type: Journal ArticleFeed 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 ... -
