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 ...
Growth performance of mixed sex, hormonally sex reversed and progeny of YY male tilapia of the GIFT strain, Orechromis niloticus
Type: Journal Article
The 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 ...
Genetic improvement of farmed tilapias: composition and genetic parameters of a synthetic base population of Oreochromis niloticus for selective breeding
Type: Journal Article
The 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 ...
Heritability estimates and response to selection for growth of Nile tilapia (Oreochromis niloticus) in low-input earthen ponds
Type: Journal Article
This study presents results of two generations of selection (G1 and G2) for growth of Nile tilapia. The selection environment consisted of earthen ponds which were fertilized daily with 50 kg dry matter (dm)/ha chicken ...
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 ...
Mass selection for increased body weight at harvest over five generations in silver barb, Puntius gonionotus
Type: Conference Paper
Silver barb (Puntius gonionotus Bleeker 1850) is an Asian carp that is popular as a food fish. It is distributed throughout Thailand in rivers, canals, reservoirs and swamps. It is also cultured in ponds and paddy fields. ...
Genetic parameters and response to selection for live weight in the GIFT strain of Nile Tilapia (Oreochromis niloticus)
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. ...
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 ...
Can the global adoption of genetically improved farmed fish increase beyond 10%, and how?
Type: Journal Article
The annual production from global aquaculture has increased rapidly from 2.6 million tons or 3.9% of the total supply of fish, shellfish and mollusks in 1970, to 66.7 million tons or 42.2% in 2012, while capture fisheries ...
