Effect of the filter-feeder silver carp on the water quality of fertilized earthen ponds and Nile tilapia production
Type: Journal Article
The objective of this study is to test the effect of silver carp on water quality and tilapia yield.
Trials to improve the response of Orechromis niloticus to Aeromonas hydrophila vaccine using immunostimulants (garlic, Echinacea) and probiotics (Organic Green and Vet-Yeast)
Type: Journal Article
Aquaculture is a promising sector of fish industry in the world with about 80 million tones being produced annually. The development of aquaculture faced several constraints; among these are diseases constituting the ...
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) ...
Effect of gypsum treatment on water quality parameters and fish performance in fertilized polyculture earthen ponds
Type: Journal Article
This experiment aimed to study the effect of agriculture gypsum treatment in aquaculture ponds (to raise water total hardness) on the physico-chemical and biological parameters of pond water and fish performance in a ...
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 ...
Comparison of technical and economic performance of fresh and salted fish processors in Lake Nasser
Type: Journal Article
The current study aims to compare the technical and economic performance of salted and fresh fish processing associated with Lake Nasser fisheries. The study concluded that investment cost in slated fish processing is lower ...

Type: Journal Article
In the present study, the levels of iron, zinc, cadmium, copper, lead, manganese, and calcium in muscle and liver tissues were investigated in different species of commercially available farmed fishes (Nile tilapia, striped ...
Colorimetric assay for the in vitro evaluation of Saprolegniabiofilm inhibitors
Type: Journal Article
Oomycete infections caused by Saprolegnia species represent an escalating problem in sustainable aquaculture development. This could be attributed to the ban of Malachite green and other carcinogenic agents aims at killing ...
Productivity, capital mobilization and moral hazard in fisheries share contracts: Lake Nasser, Egypt
Type: Journal Article
As part of an international research project on reservoir fisheries productivity in developing countries, this paper examines contractual relations in the Lake Nasser fishery, seeking to understand why so many seemingly ...
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%). ...
