Age and growth of three species of Lake Victoria fish determined by means of otolith daily growth rings
Type: Journal Article
The sagittal otoliths of Lates niloticus, Haplochromis obesus, and Oreochromis niloticus from Lake Victoria were examined for daily growth rings using scanning electron microscopy. In the three species the increments were ...
Employment generation in the Egyptian aquaculture value chain: implications for meeting the Sustainable Development Goals (SDGs).
Type: Journal Article
Egypt faces multiple interlinked challenges such as unemployment, poverty and gender inequality that pose tremendous barriers in the current efforts to achieve sustainable development. Aquaculture is a primary sector of ...
Value chain analysis of the aquaculture feed sector in Egypt
Type: Journal Article
This study was carried out to evaluate the value chain performance of the aquaculture feed sector in Egypt, in terms of value addition, employment and profitability. The strengths and weaknesses of each link of the value ...
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 ...
Performance of emergent aquaculture technologies in Myanmar; challenges and opportunities
Type: Journal Article
This paper assesses the performance of small-scale aquaculture technologies and factors influencing production, associated income and fish consumption of such technologies within agri-food farming systems in Myanmar.
Approaches to national fish breeding programs: pointers from a tilapia pilot study
Type: Journal Article
Details are given of a framework for developing breeding programmes using experience from the Genetic Improvement of Farmed Tilapias project which focussed on Nile tilapias (Oreochromis niloticus ). The following aspects ...
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 ...

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 ...
Fitting growth with the von Bertalanffy growth function : a comparison of three approaches of multivariate analysis of fish growth in aquaculture experiments
Type: Journal Article
Three approaches for multivariate analysis of fish growth in aquaculture experiments with Nile tilapia (Oreochromis niloticus niloticus L.) based on the von Bertalan¡y growth curve are presented and compared. The approaches ...
