Effect of using periphyton substrate (Bamboo stems) on water quality, phytoplankton, zooplankton, periphyton and growth performance for tilapia, mullet and catfish in earthen ponds
Type: Journal Article
This experiment shows that the bamboo substrate improved water quality, survival rate and total production of fish.
Effect Of Different Prepared Antigens Of Pseudomonas fluorescens On Specific And Non-Specific Immune Response Of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
The current work aimed to study four different prepared Ps. fluorescensantigens (formalin killed bacterin, extracellular product (ECP) suspension, sonicated cells (SC) suspension and mixture of ECP and SC suspension) to ...
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 ...
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 ...
Assessment of immune response supplemental immunoton and bovine lactoferrin as alternatives to antibiotics in nile tilapia (Oreochromis niloticus)
Type: Journal Article
An experiment was conducted to two different immunostimulants were investigated to detect changes in the activity of innate non-specific immune response, disease resistance and growth performance as alternatives to antibiotics ...
Bio-economic evaluation of African Catfish (Clarias gariepinus) interaction with Nile Tilapia (Oreochromis niloticus) in low input system and its effect on water quality
Type: Journal Article
This study aims to determine the best stocking rate of African catfish (Clarias gariepinus) as a predator to control unwanted tilapia recruits in a bilyculture system and to assess the effects of that on fish growth, water ...
Attenuated virulence of pigment-producing mutant of Aeromonas veronii bv. sobria in HeLa cells and Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Aeromonas species are potential water/foodborne pathogens, whereas Aeromonas veronii bv. sobria is one of the most virulent species to human and fish. Most current experimental evidence has publicized that suicide plasmid ...
Relative performance of two Nile tilapia (Oreochromis niloticus Linnaeus) strains in Egypt: The Abbassa selection line and the Kafr El Sheikh commercial strain
Type: Journal Article
The Abbassa selection line (developed by selective breeding) and the Kafr El Sheikh commercial strain (widely used in Egypt), both Oreochromis niloticus, were compared at two stocking densities (two and four fish m-2). ...
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 ...
