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 parameters for survival during the grow-out period in the GIFT strain of Nile tilapia (Oreochromis niloticus) and correlated response to selection for harvest weight
(2015)Type: Journal ArticleThe aims of this study were the estimation of genetic parameters for survival rate from tagging until harvest and the evaluation of the correlated response in survival rate to selection for harvest weight in the genetically ... -
Genetic parameters for uniformity of harvest weight and body size traits in the GIFT strain of Nile tilapia
(2016)Type: Journal ArticleAnimal breeding programs have been very successful in improving the mean levels of traits through selection. However, in recent decades, reducing the variability of trait levels between individuals has become a highly ... -
Genetic quality of cultured tilapia stocks in Africa
(2008)Type: Journal ArticleAfrican aquaculture is poised for rapid expansion. However, one of the key constraints holding back growth of the sector is the poor quality of the fish stocks available for culture. The problems of declines in growth ... -
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 variance for uniformity of harvest weight in Nile tilapia (Oreochromis niloticus)
(2016)Type: Journal ArticleCompetition for resources is common in aquaculture, which inflates the variability of fish body weight. Selective breeding is one of the effective approaches that may enable a reduction of size variability (or increase in ... -
Genetic variation in lytic activities of blood serum from Nile tilapia and genetic associations with survival and body weight
(1999)Type: Journal ArticleThe objective of the present investigation was to determine the genetic variation in lysozyme activity and SH activity in blood serum from a family material of Nile tilapia (O. niloticus) and to study the genetic associations ... -
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 ... -
Genetically Improved Farmed Tilapia (GIFT)
(2015)Type: BriefGenetic improvement through selective breeding has been used for millennia on crops and livestock, but up until the 1980s, little had been done to utilize this process for farmed fish. In response to the inadequate supply ... -
Genetically improved farmed tilapia (GIFT) selective breeding program
(2022)Type: PresentationWorldFish Genetics Workshop 2022 - ppt presentation about the history, present and future of the GIFT tilapia selective breeding program. -
Genetically improved rohu (Labeo rohita) for Bangladesh
(2020)Type: BriefThe WorldFish Rohu Genetic Improvement Program aims to substantially increase aquaculture productivity in Bangladesh by developing and disseminating rapidly growing rohu to farmers. Genetically improved rohu seed will be ... -
Genetically improved rohu (Labeo rohita) for Bangladesh (Bangla version)
(2020)Type: BriefThe WorldFish Rohu Genetic Improvement Program aims to substantially increase aquaculture productivity in Bangladesh by developing and disseminating rapidly growing rohu to farmers. Genetically improved rohu seed will be ... -
Genetically improved rohu carp is now in the hands aof Bangaldeshi farmers
(2021)Type: BlogMost farmers of livestock and crops have long had access to genetically improved breeds and varieties, but that has not been the case for carp farmers such as Shafiujjaman Momin from Bagatipara upazila ... -
Genetics of adaptation in rainbow trout: a multi disciplinary approach
(2010)Type: Conference PaperAbility of fish to adapt to changing environments and stressors is a key trait for breeders, especially when they sell eggs or young fish all over the world. So far, this ability has not been introduced in any breeding ... -
Genetics of flesh quality in fish
(2011)Type: Journal ArticleGenetic improvement has led to substantial increase in productivity in farmed animals and in tropical fin fish, this is evident in tilapia. The GIFT (Genetically Improved Farmed Tilapia) strain of Nile tilapia (Oreochromis ... -
Genetics of flesh quality in fish
(2010)Type: Conference PaperFlesh quality has gained importance among consumers and in the aquaculture industry because it is directly related to human health and nutrition. Flesh quality comprises several different (freshness, appearance, smell, ... -
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 architecture of selection for adaptation to challenging environments in aquaculture
(2022)Type: ThesisAquaculture, including freshwater and marine farming, has been important for global fish production during the past few decades. However, climate change presents a major risk threatening both quality and quantity of ... -
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 ... -
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 ...
