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 ...
Relevance of a rapid appraisal approach to identify locally available feed ingredients to small-scale Nile tilapia (Oreochromis niloticus L.) aquaculture
Type: Journal Article
Applications of a rapid appraisal approach to identify locally available feed ingredients in feed formulation, production, and socio-economics of Nile tilapia aquaculture in Bangladesh are discussed. Three diets of 35%, ...
Can sexual dimorphism and body shape be altered in Nile tilapia (Oreochromis niloticus) by genetic means?
Type: Journal Article
The objective of this study was to estimate genetic parameters in GIFT (Genetically Improved Farmed Tilapia), especially focusing on the genetic correlation between trait expressions in both sexes and among measurements ...
Effect of some immunostimulants as feed additives on the survival and growth performance of Nile tilapia, Oreochromis niloticus and their response to artificial infection
Type: Journal Article
Four plant based immunostimulants (Echinacea purpurea 0.25 and 1.0 ppt, Allium sativum 3 %, Nigella sativa 3% and Origanum marjorana 2 and 3% and mixture of Allium sativum , Nigella sativa 3:1, 1:3 and 3:3%, respectively ...
Influence of phenol pollution on Nile tilapia (Oreochromis niloticus)
Type: Report
In this study a field investigation was done by collection of water and Nile tilapia (Oreochromis niloticus) from Helwan (branch of Nile River), El- Abbassa earthen ponds and Bahr El-Baqar fish ponds every 4 months during ...
Policy on the transfer of genetically improved Farm Tilapia (GIFT) from Asia to Africa by the WorldFish Center
Type: Brief
The Mission of The WorldFish Center is to ‘reduce poverty and hunger through improved fisheries and aquaculture’. We work to achieve this through relevant research, development and technology transfer, partnerships, capacity ...
Simulation of optimal harvesting strategies for small-scale mixed-sex tilapia (Oreochromis shiranus Boulenger 1896) ponds using a bio-economic model
Type: Journal Article
A cohort-based bio-economic biomass growth and economic model, validated with data from experiments conducted in Malawi, was used to identify an optimal harvesting strategy for mixed-sex tilapia ponds.Three harvesting ...
Decentralised Nile tilapia seed production
Type: Book Chapter
Local production of mixed sex Nile tilapia in irrigated rice fields has been introduced, established and then spread through farmer-to farmer contact in Northwest Bangladesh benefiting poor households in a number of ways. ...
Mass spawning of Oreochromis niloticus for fry production: threats and opportunities for small-scale aquaculture and selective breeding
Type: Book Chapter
Mass selection based on mass spawning can present a feasible and low-cost selective breeding scheme. In mass spawning, however, mating is not controlled and a small number of breeding individuals may account for a ...
Growth performance and feed utilization of Nile tilapia Oreochromis niloticus (Linnaeus, 1758) and tilapia galilae Sarotherodon galilaeus (Linnaeus, 1758) fingerlings fed plant protein-based diets
Type: Journal Article
This study was designed to determine the effect of complete substitution of fish meal (FM) by three plant protein sources including extruded soybean meal (SBM), extruded full-fat soybean (FFSB) and corn gluten meal (CGM) ...
