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 ...
Effects of C/N ratio and periphyton substrates on pond ecology and production performance in giant freshwater prawn Macrobrachium rosenbergii (De Man, 1879) and tilapia Oreochromis niloticus (Linnaeus, 1758) polyculture system
Type: Journal Article
The production performances of giant freshwater prawn Macrobrachium rosenbergii and Nile tilapia Oreochromis niloticus in C/N-controlled periphyton-based polyculture systems were evaluated in triplicate. The result of this ...
Exploring the trophic structure in organically fertilized and feed-driven tilapia culture environments using multivariate analyses
Type: Journal Article
Reports of similar yields in manure and feed-driven tilapia culture environments raise questions on food utilization in these environments. The possibility that similar production rates are because of utilization of different ...
Is tilapia mortality a latent concern for the aquaculture sector of Bangladesh? An epidemiology and health economic impact study
Type: Journal Article
Tilapia are the 3rd most cultured aquaculture species in global aquaculture, produced in over 170 countries. Bangladesh is the world's fourth-largest tilapia producer and yet only few studies have been conducted to understand ...
Field studies on prevention and biological control of the cyanobacterial blooms using Chlorella and Scenedesmus in the Nile tilapia farms
Type: Journal Article
This study aimed to investigate the use of green algae Chlorella elliposoidea (Gerneck) + Scenedesmus bijuga (Turpin) Lageh as prevention and biological control treatment of cyanobacterial blooms as field application.
Effect of using periphyton substrate (Bamboo stems) on water quality, phytoplankton, zooplankton, periphyton and growth performance for tilapia, mullet and catfish in earthen ponds
Type: Journal Article
This experiment shows that the bamboo substrate improved water quality, survival rate and total production of fish.
Effect Of Different Prepared Antigens Of Pseudomonas fluorescens On Specific And Non-Specific Immune Response Of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
The current work aimed to study four different prepared Ps. fluorescensantigens (formalin killed bacterin, extracellular product (ECP) suspension, sonicated cells (SC) suspension and mixture of ECP and SC suspension) to ...
Investment Appraisal of Genetic Improvement Programs in Nile tilapia (Oreochromis Niloticus)
Type: Journal Article
The economic benefit derived from a genetic improvement program with Nile tilapia (Oreochromis niloticus) was examined from a national perspective. An industry structure was assumed whereby the genetic improvement program ...
Analysis of research for the development of tilapia farming: an interdisciplinary approach is lacking
Type: Journal Article
Tilapias, particularly Oreochromis spp., are farmed throughout the tropics and subtropics but most of the production comes from a few Asian countries. Global production increased by about 13%/yr from 1985 to 1989. A global ...
