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 ...
Impact of substitution of fish meal by high protein distillers dried grains on growth performance, plasma protein and economic benefit of striped catfish (Pangasianodon hypophthalmus)
Type: Journal Article
Modern aquaculture requires the reduction of the feeds cost, which can partly be achieved by minimal use of dietary animal protein. Therefore, this experiment assessing the nutritional potential of using high protein ...
Prospects of fish supply-demand and its implications for food and nutrition security in Egypt
Type: Journal Article
Aquaculture plays an increasingly important role in meeting the rising global demand for fish fuelled by economic and demographic growth. However, in many middle-income countries, aquaculture is constrained by rising labour ...
COVID-19 impacts and adaptations in Asia and Africa’s aquatic food value chains
Type: Journal Article
The COVID-19 pandemic is a shock affecting all areas of the global food system. We tracked the impacts of COVID-19 and associated policy responses on the availability and price of aquatic foods and production inputs during ...
Metabolic growth, plankton selectivity, haemato-biochemical and intestinal morphometry of Nile tilapia (Oreochromis niloticus) fed a lysine-deficient diet in earthen ponds
Type: Journal Article
Sustainable aquaculture requires the efficient use of natural pond resources as well as supplements to meet the dietary requirements of fish species. However, aquaculture diets are often produced without considering the ...
Nitrogen retention, nutrient digestibility and growth efficiency of Nile tilapia (Oreochromis niloticus) fed dietary lysine and reared in fertilized ponds
Type: Journal Article
Two diets were formulated, a low lysine (LowL) and a balanced lysine diet (BalL), containing 9.10 and 13.10 g lysine kg−1 feed, respectively. Twenty fish (30.2 ± 1.9 g) per tank were stocked in 110-L tanks, mounted in a ...
Fisheries management based on gear selectivity of a tropical reservoir, Lake Nasser, Egypt
Type: Journal Article
Lake Nasser, a large man-made tropical reservoir, located in the southern part of Egypt. The lakes’ fisheries have undergone steady decrease during the last 10 years obscuring its potential for sustainability. Fisheries ...
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 ...
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 ...
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 ...
