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.
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 ...
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 ...
Effects of stocking density on production and economics of all-male tilapia (Oreochromis niloticus) culture in a rain fed rice-fish ecosystem
Type: Journal Article
Effects of stocking density on the growth, production, and economics of all-male tilapia (Oreochromis niloticus) were investigated in a rain-fed rice-fish ecosystem for a period of 120 days. Fish were stocked at the rate ...
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 ...
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 ...
