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 ...
Price setting in markets for Egyptian farmed fish
Type: Journal Article
This article investigates the relation between fish supply volumes and sales values in El-Obour wholesale market. The study also examines market cointegration between farmed tilapia and imported wild frozen fish (tilapia, ...
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 ...
Production economics of Nile Tilapia (Oreochromis niloticus) pond culture in El-Fayum Governorate, Egypt
Type: Journal Article
Econometric techniques were used to estimate a production function for tilapia pond culture in El-Fayum Governorate, Egypt, utilizing cross-sectional field data. Explanatory variables were feed, initial stocking weight, ...
Tilapia major clinical signs (Odia version)
Type: Poster
The purpose of this poster is to enhance the capacity of hatcheries, nurseries, grow-out farmers and extension service providers to recognize and report tilapia diseases. Prevention, early recognition, diagnosis and rapid ...
Genetic parameters and correlated responses in female reproductive traits in the GIFT strain
Type: Journal Article
The aim of this study was to examine genetic variation in reproductive traits and to estimate correlated responses in such traits to selection for high growth rate in the GIFT strain of Nile tilapia (Oreochromis niloticus).
Indonesia's Aquaculture Sector
Type: Poster
A snapshot of aquaculture development in Indonesia.
Genetic improvement of Israeli blue (Jordan) tilapia, Oreochromis aureus (Steindachner), through selective breeding for harvest weight
Type: Journal Article
Genetic parameters and selection responses were obtained for harvest body weight of blue tilapia (Oreochromis aureus) from data collected over three generations in a selected population. A total of 18 194 records representing ...
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 ...
