Approaches to national fish breeding programs: pointers from a tilapia pilot study
Eknath, A.E.; Bentsen, H.B.; Gjerde, B.; Tayamen, M.M.; Abella, T.A.; Gjedrem, T.; Pullin, R.S.V. (1991)Type: Journal ArticleDetails are given of a framework for developing breeding programmes using experience from the Genetic Improvement of Farmed Tilapias project which focussed on Nile tilapias (Oreochromis niloticus ). The following aspects ... -
Genetic improvement and dissemination of rohu (labeo rohita, Ham.) in India
Das Mahapatra, K.; Saha, J.N.; Sarangi, N.; Jana, R.K.; Gjerde, B.; Nguyen, N.H.; Khaw, H.L.; Ponzoni, R.W. (2007)Type: Book ChapterExperts carried out selective breeding of Rohu carp for greater harvest weight and yielded an average of 17% genetic gain per generation in 5 generations of selection. -
Genetic improvement of farmed tilapias: composition and genetic parameters of a synthetic base population of Oreochromis niloticus for selective breeding
Eknath, A.E.; Bentsen, H.B.; Ponzoni, R.W.; Rye, M.; Nguyen, N.H.; Thodesen, J.; Gjerde, B. (2007)Type: Journal ArticleThe present study is based on data recorded from fish of the third generation of the GIFT project (Genetic Improvement of Farmed Tilapias). The objective of the study was to compose a synthetic base population of Nile ... -
Genetic improvement of farmed tilapias: Genetic parameters for body weight at harvest in Nile tilapia (Oreochromis niloticus) during five generations of testing in multiple environments
Bentsen, H.B.; Gjerde, B.; Nguyen, N.H.; Rye, M.; Ponzoni, R.W.; Palada de Vera, M.S.; Bolivar, H.L.; Velasco, R.R.; Danting, J.C.; Dionisio, E.E.; Longalong, F.M.; Reyes, R.A.; Abella, T.A.; Tayamen, M.M.; Eknath, A.E. (2012)Type: Journal ArticleThe main objective of this paper was to report more reliable estimates of the genetic variation and the genotype by test environment interaction for harvest body weight in the GIFT population in the Philippines than could ... -
Genetic improvement of farmed tilapias: growth performance in a complete diallel cross experiment with eight strains of Oreochromis niloticus
Bentsen, H.B.; Eknath, A.E.; Palada-de Vera, M.S.; Danting, J.C.; Bolivar, H.L.; Reyes, R.A.; Dionisio, E.E.; Longalong, F.M.; Circa, A.V.; Tayamen, M.M.; Gjerde, B. (1998)Type: Journal ArticleA complete diallel cross experiment was carried out with eight strains of Nile tilapia (Oreochromis niloticus). The strains represented four wild populations collected from various locations in Africa and four populations ... -
Genetic improvement of farmed tilapias: Response to five generations of selection for increased body weight at harvest in Oreochromis niloticus and the further impact of the project
Bentsen, H.B.; Gjerde, B.; Eknath, A.E.; de Vera, M.S.P.; Velasco, R.R.; Danting, J.C.; Dionisio, E.E.; Longalong, F.M.; Reyes, R.A.; Abella, T.A.; Tayamen, M.M.; Ponzoni, R.W. (2017)Type: Journal ArticleSelection for increased body weight at harvest in Nile tilapia (Oreochromis niloticus) was carried out for five generations from 1991 to 1996, as a part of the project Genetic Improvement of Farmed Tilapias (GIFT). The ... -
Genetic parameter and genotype by environment interaction for body weight of Oreochromis shiranus
Maluwa A. O.; Gjerde, B.; Ponzoni, R.W. (2006)Type: Journal ArticleGenetic and phenotypic parameter estimates for tagging and harvest body weights were obtained from the F1 base (377 offspring of 59 full-sib families), F2 (1241 offspring of 52 full- and 33 half-sib families) and F3 (1052 ...
