Assessment of the impact of dissemination of genetically improved Abbassa Nile tilapia strain (GIANT-G9) versus commercial strains in some Egyptian governorates
Type: Journal Article
WorldFish initiated a selective breeding program in Abbassa--Egypt to develop and produce the genetically improved Nile tilapia strain known as “Genetically Improved Abbassa Nile tilapia (GIANT)”, adopting the same technology ...
Genetic variation in wild populations and farmed stocks of Nile tilapia (Oreochromis niloticus) in Madagascar
Type: Journal Article
Four farmed stocks and four wild populations of Nile tilapia (Oreochromis niloticus), which was first introduced to Madagascar sixty years ago, were assayed for genetic variation at nine microsatellite loci to determine ...
Economic impacts of ponds management on water quality and growth performance of fish in polyculture
Type: Journal Article
The present study was conducted to evaluate the economics of the fish farms management under different systems and different water sources and its impact on the growth performance of fish in polyculture.
Effect of dietary protein level on fish growth, economic and ecological performance of three types of feed for Nile tilapia (Oreochromis Niloticus)
Type: Internal Report
With a growing world population, food production needs to increase as well. Part of the human diet is fish, and with world fisheries declining, the aquaculture industry is increasing. Nile tilapia is a major aquaculture ...
Apparent digestibility coefficients of local palm kernel cakes, rice bran, maize bran and sago flour in the GIFT strain of tilapia (Oreochromis niloticus)
Type: Journal Article
An experiment was conducted to estimate the apparent digestibility coefficients (ADC) of macronutrients and energy of local palm kernel cakes, rice bran, maize bran and sago flour available in tilapia, Oreochromis niloticus ...
Effect of female weight on reproductive performance of nile tilapia (Oreochromis niloticus)
Type: Conference Paper
The present study aimed to investigate the effect of broodstock size on the reproductive performance of Nile tilapia and to see whether this identifies possible broodstock management strategies that may be adopted by ...
Genetic diversity of Nile tilapia (Oreochromis niloticus) throughout West Africa
Type: Journal Article
Nile tilapia (Oreochromis niloticus) is a globally significant aquaculture species rapidly gaining status as a farmed commodity. In West Africa, wild Nile tilapia genetic resources are abundant yet knowledge of fine-scale ...
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 ...
Effect of Photoperiod, Dietary Protein and Temperature on Reproduction in Nile Tilapia (Oreochromis niloticus)
Type: Conference Paper
Photoperiod, crude protein level and water temperature were studied for their effects on reproductive performance and egg hatchability in Nile tilapia (Oreochromis niloticus).
Transcriptome analysis of liver elucidates key immune-related pathways in Nile tilapia Oreochromis niloticus following infection with tilapia lake virus
Type: Journal Article
Nile tilapia (Oreochromis niloticus) is one of the most important aquaculture species farmed worldwide. However, the recent emergence of tilapia lake virus (TiLV) disease, also known as syncytial hepatitis of tilapia, has ...
