Gender-inclusive innovations for aquatic food systems transformation
(2022)Type: PresentationBangladesh is a highly vulnerable country to climate change, variability and extremes. Seasonal signature of extreme heat, heavy and mean precipitation changes, floods and cyclones are few among the challenges. These are ... -
Genetic analysis of Nile tilapia (Oreochromis niloticus) selection line reared in two input environments
(2009)Type: Journal ArticleAscertaining the appropriate selection environment for Nile tilapia (Oreochromis niloticus) in Africa is a critical issue. Two data sets derived from two selection lines originating from a common base population were ... -
Genetic analysis of the GIFT strain (Nile Tilapia, Oreochromis niloticus) in Malaysia
(2010)Type: Conference PaperThe Genetically Improved Farmed Tilapia (GIFT) strain is well known worldwide because of its high performance. A first phase of the project ended in 1997 after five generations of selection. In 2002, the GIFT population ... -
Genetic and environmental factors affecting growth of Nile tilapia (Oreochromis niloticus) juveniles: Modelling spatial correlations between hapas
(2006)Type: Journal ArticleThe aim of this study was to quantify the environmental and genetic effects on early growth of Nile tilapia, Oreochromis niloticus. -
Genetic and non-genetic indirect effects for harvest weight in the GIFT strain of Nile tilapia (Oreochromis niloticus)
(2016)Type: Journal ArticleThe main objective of this study was to quantify the heritable variation for growth rate of GIFT, and the contribution of IGEs to this heritable variation. Here we describe the experiment conducted for this purpose, and ... -
Genetic aspects of conservation and cultivation of giant clams
(1993)Type: Conference ProceedingsReport of a 1992 workshop. Includes discussion papers on population genetics, broodstock establishment, preservation of biodiversity, hatchery procedures, and identifying strains; country papers from Australia, Fiji, Palau, ... -
Genetic characterization and antimicrobial profiling of bacterial isolates collected from Nile tilapia (Oreochromis niloticus) affected by summer mortality syndrome
(2022)Type: Journal ArticleIn recent years, Egyptian tilapia aquaculture has experienced mortality episodes during the summer months. The causative agents responsible for such mortalities have not been clearly identified. A total of 400 fish specimens ... -
Genetic characterization of the Aphyosemion calliurum species group and description of a new species from this assemblage: A. campomaanense (Cyprinodontiformes: Aplocheiloidei: Nothobranchiidae) from Southern Cameroon
(2009)Type: Journal ArticleThe Aphyosemion calliurum species group is poorly diagnosed by chromatic and meristic characteristics leading various authors to propose different species as members. We used partial sequence of the mitochondrial cytochrome ... -
Genetic considerations on acquisition and maintenance of reference populations of tilapia
(1988)Type: Journal ArticleThe maintenance of reference populations of Tilapia is discussed, examining genetic considerations to be taken into account to conserve the gene pool to prevent genetic drift and prevent detrimental levels of inbreeding. ... -
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 diversity and selective breeding of red common carps in China
(2001)Type: Journal ArticleChina has a very rich genetic diversity in common carp (Cyprinus carpio) and the red common carp plays an important role in Chinese aquaculture and genetic studies. Selective breeding, particularly crossbreeding has been ... -
Genetic diversity in wild stocks of the giant freshwater prawn (Macrobrachium rosenbergii): implications for aquaculture and conservation
(2003)Type: Journal ArticleThe giant freshwater prawn (Macrobrachium rosenbergii) is cultured widely around the world but little is known about the levels and patterns of genetic diversity in either wild or cultured stocks. Studies have suggested ... -
Genetic diversity of Nile tilapia (Oreochromis niloticus) throughout West Africa
(2020)Type: Journal ArticleNile tilapia (Oreochromis niloticus) is a globally significant aquaculture species rapidly gaining status as a farmed commodity. In West Africa, wild Nile tilapia genetic resources are abundant yet knowledge of fine-scale ... -
Genetic diversity of tilapia lake virus genome segment 1 from 2011 to 2019 and a newly validated semi-nested RT-PCR method
(2020)Type: Journal ArticleThe gene of RNA viruses, encoding RNA-directed RNA polymerase (RdRp) is relatively conserved due to its crucial function in viral genome replication and transcription making it a useful target for genetic diversity study ... -
Genetic enhancement and conservation of aquatic biodiversity in Africa
(2002)Type: Journal ArticleThere is a pressing need to enhance fish production in Africa through improved farm management and the use of improved fish breeds and/or alien species in aquaculture while at the same time conserve the aquatic genetic ... -
Genetic evaluation of a complete diallel cross involving three populations of freshwater prawn (Macrobrachium rosenbergii) from different geographical regions of India
(2011)Type: Journal ArticleEstimates of additive genetic, reciprocal and average heterosis effects were obtained from a three by three complete diallelcross experiment for giant freshwater prawn Macrobrachium rosenbergii. The data were generated in ... -
Genetic evaluation of growth and survival at 6 weeks old fry of Egyptian Nile Tilapia (Oreochromis niloticus) between improved Abbassa and commercial Manzala strains in a diallel crossing
(2016)Type: Journal ArticleThe main objectives of this study were to evaluate growth performance and estimate line crossing parameters of improved Abbassa tilapia strain and a commerciall Manzala strain within a complete diallel cross at 6 weeks old ... -
