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 ... -
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 environmental interaction for live weight between two production environments in the GIFT strain (Nile tilapia, Oreochromis niloticus)
(2009)Type: Conference PaperA genotype by environmental interaction study was conducted using the live weight data collected from three discrete spawning seasons of Genetically Improved Farmed Tilapia selective breeding program in Malaysia. Two ... -
Genotype by production environment interaction in the GIFT strain of Nile tilapia (Oreochromis niloticus)
(2012)Type: Journal ArticleThree discrete generations of GIFT fish (Nile tilapia strain, Oreochromis niloticus; a total of 10,065 fish with pedigree and phenotypic information) were tested in pond and cage culture environments to determine genotype ... -
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 ... -
Geography limits island small-scale fishery production
(2017)Type: Journal ArticleInteracting social and ecological processes shape productivity and sustainability of island small-scale fisheries (SSF). Understanding limits to productivity through historical catches help frame future expectations and ... -
Getting beneath the surface in program planning, monitoring and evaluation: Learning from use of participatory action research and theory of change in the CGIAR Research Program on Aquatic Agricultural Systems
(2016)Type: Journal ArticleMany rural poor and marginalized people strive to make a living in social-ecological systems that are characterized by multiple and often inequitable interactions across agents, scale and space. Uncertainty and inequality ... -
