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 ...
Lessons from the breeding program on common carp in Hungary
Type: Conference Paper
Common carp is one of the most important cultured freshwater fish species in the world. Its production in freshwater areas is the second largest in Europe after rainbow trout. Common carp production in Europe was 146,845 ...
Genetically Improved Farmed Tilapia (GIFT)
Type: Brief
Genetic improvement through selective breeding has been used for millennia on crops and livestock, but up until the 1980s, little had been done to utilize this process for farmed fish. In response to the inadequate supply ...
Tilapia: The plain truth (Khmer version)
Type: Poster
This infographic is an overview of tilapia as a nutritious inexpensive and environmentally friendly food.
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 ...
Genetic variance for uniformity of harvest weight in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Competition for resources is common in aquaculture, which inflates the variability of fish body weight. Selective breeding is one of the effective approaches that may enable a reduction of size variability (or increase in ...
Closing the yield gap: improving production efficiency in smallholder farms of Nile tilapia through selective breeding
Type: Thesis
The aim of this thesis was to optimise the breeding program of Nile tilapia for a smallholder production system, thereby contributing to closing the yield gap. From Chapter 2 to 4, we generated information that can be used ...
Genetic diversity in wild stocks of the giant freshwater prawn (Macrobrachium rosenbergii): implications for aquaculture and conservation
Type: Journal Article
The giant freshwater prawn (Macrobrachium rosenbergii) is cultured widely around the world but little is known about the levels and patterns of genetic diversity in either wild or cultured stocks. Studies have suggested ...
Prátika Jestaun Di’ak Liu ba Produsaun Fini Ikan Tipaia Monoseksu: Matadalan ilustrada (Better management practices for monosex tilapia seed production: An illustrated guide)
Type: Manual
The booklet explains the better management practices (BMP) for producing high-quality genetically improved farmed tilapia (GIFT) monosex seed. These simple and low-cost methods have been tested and proven over five years ...
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 ...
