A comparison of GIFT and red tilapia for fillet yield and sensory attributes of flesh quality assessed by trained panel
(2006)Type: Conference PaperTilapia is a tropical freshwater fish, predicted to become the largest aquaculture production in the world, after carps, shrimp and salmonids, in the present century (Fitzsimmons, 2000). In Malaysia 85 per cent of the ... -
Can sexual dimorphism and body shape be altered in Nile tilapia (Oreochromis niloticus) by genetic means?
(2007)Type: Journal ArticleThe objective of this study was to estimate genetic parameters in GIFT (Genetically Improved Farmed Tilapia), especially focusing on the genetic correlation between trait expressions in both sexes and among measurements ... -
Correlated response in fillet weight and yield to selection for increased harvest weight in genetically improved farmed tilapia (GIFT strain), Oreochromis niloticus
(2010)Type: Journal ArticleA data set consisting of 5532 slaughter records collected over three generations from a selection program for increased harvest body weight in the GIFT strain of Nile tilapia (Oreochromis niloticus) was used to estimate ... -
Flesh characteristics: estimation of genetic parameters and correlated responses to selection for growth rate in the GIFT strain
(2014)Type: Journal ArticleGenetically improved farmed tilapia (GIFT) has undergone ten generations of selection for harvest body weight in Malaysia, but there have been no reports on genetic parameters for flesh characteristics for this strain. In ... -
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 improvement of Nile tilapia (Oreochromis niloticus) with special reference to the work conducted by the WorldFish Center with the GIFT strain
(2011)Type: Journal ArticleWe mainly (but not exclusively) draw on research and development work carried out by The WorldFish Center (WorldFish). We review in detail the current state of development of a selection program that has had a main focus ... -
Genetic improvement of Nile tilapia (Oreochromis Niloticus): present and future
(2008)Type: Conference PaperWe mainly (but not exclusively) draw upon research and development work carried out by The WorldFish Center (WorldFish). We review the current state of development of selection programs that have had a main focus on growth ... -
Genetic improvement programs for red tilapia Oreochromis spp in Asia
(2011)Type: Conference PaperRed tilapia (Oreochromis spp) has become popular in Asian countries due to its greater economic value relative to Nile tilapia. As there is a growing demand for quality seed of this species, the WorldFish Center has initiated ... -
Genetic parameters and correlated responses in female reproductive traits in the GIFT strain
(2016)Type: Journal ArticleThe aim of this study was to examine genetic variation in reproductive traits and to estimate correlated responses in such traits to selection for high growth rate in the GIFT strain of Nile tilapia (Oreochromis niloticus). -
Genetic parameters and response to selection for live weight in the GIFT strain of Nile Tilapia (Oreochromis niloticus)
(2005)Type: Journal ArticleGenetic improvement programs can increase the productivity of cultured aquatic species. Their rigorous design requires knowledge about parameters such as herit-ability and correlations among the traits under selection. ... -
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 ... -
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, ... -
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 ... -
Growth and survival rate of three genetic groups fed 28% and 34% protein diets
(2012)Type: Journal ArticleThe strain by nutrition interaction in body weight and survival rate was examined by testing three genetic groups (Selection and Control lines of the GIFT strain, and Red tilapia) at two levels of protein in the diet (28% ... -
Growth performance of mixed sex, hormonally sex reversed and progeny of YY male tilapia of the GIFT strain, Orechromis niloticus
(2009)Type: Journal ArticleThe growth performance of three experimental groups consisting of mixed sex fish (control), hormone-treated fish and progeny of YY male tilapia, all originated from the genetically improved farmed tilapia (GIFT) strain was ... -
Inbreeding and effective population size in the Malaysian nucleus of the GIFT strain of Nile tilapia (Oreochromis niloticus)
(2010)Type: Journal ArticleA fully pedigreed population of the GIFT (Genetically Improved Farmed Tilapia) strain of Nile tilapia (Oreochromis niloticus) was established in Malaysia during 2001 and 2002. The selection program was focused on the ... -
Performance and survival of three red tilapia strains (Oreochromis spp) in pond environment in Kedah state, Malaysia
(2008)Type: Conference PaperGrowth performance (body weight, standard length, body width and depth) and survival of three red tilapia (<i>Oreochromis</i> spp) strains from Malaysia, Taiwan and Thailand were evaluated using 2,867 records collected ... -
Performance of the Genetically Improved Farmed Tilapia (GIFT) strain over ten generations of selection in Malaysia
(2014)Type: Journal ArticleA selection programme using Best Linear Unbiased Prediction (BLUP) method for the estimation of genetic merit was implemented by the Department of Fisheries Malaysia (DOF) in collaboration with the WorldFish Centre. This ... -
