Considerations about effective dissemination of improved fish strains
Type: Working Paper
Aquaculture production systems in developing countries are largely based on the use of unimproved species and strains. As knowledge and experience are accumulated in relation to the management, feeding and animal health ...
Genetic evaluation of a complete diallel cross involving three populations of freshwater prawn (Macrobrachium rosenbergii) from different geographical regions of India
Type: Journal Article
Estimates 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 analysis of the GIFT strain (Nile Tilapia, Oreochromis niloticus) in Malaysia
Type: Conference Paper
The 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): present and future
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 ...
Estimation of genetic change in the GIFT strain by comparing contemporary progeny produced by males born in 1991 or 2003
Type: Conference Paper
During the development of the GIFT (Genetically Improved Farmed Tilapia) strain in Philippines sperm was frozen from a sample of males from founder stocks and subsequent generations. In this paper a comparison of progeny ...
Flesh characteristics: estimation of genetic parameters and correlated responses to selection for growth rate in the GIFT strain
Type: Journal Article
Genetically 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 ...
Strain comparisons in aquaculture species: a manual
Type: Manual
When different strains or breeds of a particular species are available, the best choice is seldom immediately obvious for producers. Scientists are also interested in the relative performance of different strains because ...
Genetic and non-genetic indirect effects for harvest weight in the GIFT strain of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
The 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 ...
Selective breeding in fish and conservation of genetic resources for aquaculture
Type: Journal Article
To satisfy increasing demands for fish as food, progress must occur towards greater aquaculture productivity whilst retaining the wild and farmed genetic resources that underpin global fish production. We review the main ...
Genetics of flesh quality in fish
Type: Conference Paper
Flesh 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, ...
