Khaw H. L.; Ponzoni, R.W.; Hamzah, A.; Abu Bakar, K.R.; Kamaruzzaman, N.; Ismail, N.; Jaafar, H.; Nguyen, N.H. (2006)

Type: Conference Paper

Tilapia 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?

Nguyen, N.H.; Khaw, H.L.; Ponzoni, R.W.; Hamzah, A.; Kamaruzzaman, N. (2007)

Type: Journal Article

The 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 ...

Genetic improvement of Nile tilapia (Oreochromis Niloticus): present and future

Ponzoni, P.W.; Nguyen, N.H.; Khaw, H.L.; Kamaruzzaman, N.; Hamzah, A.; Bakar, K.R.A.; Yee, H.Y. (2008)

Type: Conference Paper

We 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 parameters and response to selection for live weight in the GIFT strain of Nile Tilapia (Oreochromis niloticus)

Ponzoni R. W.; Hamzah, A.; Tan, S.; Kamaruzzaman, N. (2005)

Type: Journal Article

Genetic 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. ...
