The future of fish in Africa: employment and investment opportunities
Type: Journal Article
One of the most pressing challenges facing food systems in Africa is ensuring availability of a healthy and sustainable diet to 2.4 billion people by 2050. The continent has struggled with development challenges, particularly ...
A comparison of the fixed input and water quality analysis methods for optimizing fertilization requirements, minimizing costs and increasing fish production in polyculture ponds
Type: Journal Article
This study aims to find a proper fertilization method to optimize nutrient requirements and a proper fertilization strategy through determining the amount as well as the period of fertilizers addition, with an aim of ...
Comparing genomic signatures of selection between the Abbassa Strain and eight wild populations of Nile tilapia (Oreochromis niloticus) in Egypt
Type: Journal Article
Domestication to captive rearing conditions, along with targeted selective breeding have genetic consequences that vary from those in wild environments. Nile tilapia (Oreochromis niloticus) is one of the most translocated ...
Pipette and paper: Combining molecular and genealogical methods to assess a Nile tilapia (Oreochromis niloticus) breeding program
Type: Journal Article
The paper compared molecular and paper records of pedigrees in a Nile tilapia breeding program, the Abbassa line in Egypt. It established a novel pipeline of checks and balances based on molecular data to correct erroneous ...
Molecular characterization, virulence profiling, antibiotic susceptibility, and scanning electron microscopy of Flavobacterium columnare isolates retrieved from Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Columnaris is a common flavobacterial disease affecting tilapia aquaculture. Flavobacterium columnare has been identified as being responsible for the heavy mortalities of earthen-pond-cultured Nile tilapia (Oreochromis ...
Key risk factors, farming practices and economic losses associated with tilapia mortality in Egypt
Type: Journal Article
Egypt is the topmost aquaculture producer in Africa and the third largest tilapia producer globally. Nile tilapia in particular is the cornerstone of fish farming in Egypt. Recently, fish farms have experienced unusual ...
Effect of garlic and yeast in the culture of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
The present study aimed to investigate the effect of both garlic and yeast (Saccharomyces cervecesa) on survival and growth performance of cultured Nile tilapia (Oreochromus niloticus), besides studying its immune stimulatory ...
Estimated costs and returns for commercial cage production of fingerlings and table-size mullet (Mugil cephalus) in Dakhlia Governorate, Egypt
Type: Journal Article
Large scale cage culture of mullet is new practice in Egypt and have not economically evaluated. The aims of this study are: to assess the economic potential of the actual practices of private mullet cage operations in ...
Genetic characterization and antimicrobial profiling of bacterial isolates collected from Nile tilapia (Oreochromis niloticus) affected by summer mortality syndrome
Type: Journal Article
In recent years, Egyptian tilapia aquaculture has experienced mortality episodes during the summer months. The causative agents responsible for such mortalities have not been clearly identified. A total of 400 fish specimens ...
Selective breeding trait preferences for farmed tilapia among low-income women and men consumers in Egypt; Implications for pro-poor and gender-responsive fish breeding programmes
Type: Journal Article
A number of studies have highlighted the promising growth of Egyptian tilapia aquaculture and the role of genetically improved strains in this development, such as the Abbassa Nile tilapia (Oreochromis niloticus, Linneaus, ...
