Differences in sexual size dimorphism among farmed tilapia species and strains undergoing genetic improvement for body weight
Type: Journal Article
Many tilapia (Oreochromis spp.) farmers produce all-male populations because of the superior growth rate of males compared to females. To investigate differences in body weight at harvest of males and females among different ...
Species composition in the Molobicus hybrid tilapia strain
Type: Journal Article
The “Molobicus” hybrid breeding programme was initiated to improve tilapia growth performance in brackish water. The base population was created by backcrossing F1 Oreochromis niloticus GIFT strains × feral O. mossambicus ...
From drawing board to dining table: the success story of the GIFT project
Type: Journal Article
As compared to crops and livestock, the genetic enhancement of fish is in its infancy. While significant progress has been achieved in the genetic improvement of temperate fish such as salmonids, no efforts were made until ...
Socioeconomics of disseminating genetically improved Nile tilapia in Asia: an introduction
Type: Journal Article
The International Center for Living Aquatic Resources Management (ICLARM) undertook a major strategic research project known as the "Genetic Improvement of Farmed Tilapias" (GIFT), with funding support from the United ...
Performance of the Genetically Improved Farmed Tilapia (GIFT) strain over ten generations of selection in Malaysia
Type: Journal Article
A 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 ...
Benchmarking the environmental performance of best management practice and genetic improvements in Egyptian aquaculture using life cycle assessment
Type: Journal Article
Egyptian aquaculture is gaining importance as an affordable and nutritious source of animal protein among Egyptians. Nile tilapia dominates production (77% of total production), followed by carps (17%) and mullets (11%). ...
Assessment of the impact of dissemination of genetically improved Abbassa Nile tilapia strain (GIANT-G9) versus commercial strains in some Egyptian governorates
Type: Journal Article
WorldFish initiated a selective breeding program in Abbassa--Egypt to develop and produce the genetically improved Nile tilapia strain known as “Genetically Improved Abbassa Nile tilapia (GIANT)”, adopting the same technology ...
A simple and inexpensive fish tagging method
Type: Journal Article
In many developing countries, availability of suitable tags for use in genetics and aquaculture research has been a problem as they are often expensive and have to be imported from other countries. A simple and inexpensive ...
Response to selection for growth in an interspecific hybrid between Oreochromis mossambicus and O. niloticus in two distinct environments
Type: Journal Article
The development of a saline tolerant tilapia strain able to grow fast is of importance in the Philippines, where 240 000 ha of brackish water ponds are available. To this end, founder hybridization between Oreochromis ...
Indirect genetic effects and inbreeding: Consequences of BLUP selection for socially affected traits on rate of inbreeding
Type: Journal Article
Social interactions often occur among living organisms, including aquatic animals. There is empirical evidence showing that social interactions may genetically affect phenotypes of individuals and their group mates. In ...
