Efficacy and safety of boric acid as a preventive treatment against Saprolegnia infection in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Saprolegniosis is a worldwide fungal-like infection affecting freshwater fishes and their eggs. Reports show high mortalities and subsequent economic losses annually from Saprolegnia infections. Most therapeutants against ...
Measuring individual feed efficiency and its correlations with performance traits in Nile tilapia, Oreochromis niloticus
Type: Journal Article
Estimating individual feed intake of fish held in groups has long been a challenge precluding precise knowledge of the individual variation of feed efficiency (FE) in fish. In this study, counts of the number of feed pellets ...
Microbial biomass (Novacq™) stimulates feeding and improves the growth performance on extruded low to zero-fishmeal diets in tilapia (GIFT strain)
Type: Journal Article
Worldwide tilapia production is rapidly growing and becoming increasingly reliant on the provision of cost-effective sustainable formulated feeds. In the paper, the authors assessed the capacity for various inclusion rates ...
Effects of supplementary feeds with different protein levels on growth and economic performances of Nile tilapia (Oreochromis niloticus) cultured in a rain-fed rice-fish ecosystem
Type: Journal Article
This study investigated the effects of supplementary feeds with different crude protein levels on the growth and economic performances of sex-reversed Nile tilapia (Oreochromis niloticus) reared in a rain-fed rice-fish ...
Development of Diversity Arrays Technology markers as a tool for rapid genomic assessment in Nile tilapia, Oreochromis niloticus
Type: Journal Article
The development of genomic markers is described for Nile tilapia, Oreochromis niloticus, using the Diversity Arrays Technology (DArT) genotype-by-sequencing platform. A total of 13 215 single nucleotide polymorphism (SNP) ...
Identification of Tilapia Lake Virus in Egypt in Nile tilapia affected by 'summer mortality' syndrome
Type: Journal Article
Egyptian fish farms have faced unexplained mortality of tilapia during the summer months in recent years. Epidemiological surveys indicated that 37% of fish farms were affected in 2015 with an average mortality rate of ...
Tilapia lake virus: a threat to the global tilapia industry?
Type: Journal Article
Tilapia lake virus (TiLV) is a recently described virus affecting wild and farmedtilapines. At present, it has been reported on three continents (Asia, Africa andSouth America) and the number of countries where the agent ...
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 ...
Genetic variation in wild populations and farmed stocks of Nile tilapia (Oreochromis niloticus) in Madagascar
Type: Journal Article
Four farmed stocks and four wild populations of Nile tilapia (Oreochromis niloticus), which was first introduced to Madagascar sixty years ago, were assayed for genetic variation at nine microsatellite loci to determine ...
