Genetic parameters for survival during the grow-out period in the GIFT strain of Nile tilapia (Oreochromis niloticus) and correlated response to selection for harvest weight
Type: Journal Article
The aims of this study were the estimation of genetic parameters for survival rate from tagging until harvest and the evaluation of the correlated response in survival rate to selection for harvest weight in the genetically ...
A comparison of the fixed input and water quality analysis methods for optimizing fertilization requirements, minimizing costs and increasing fish production in polyculture ponds
Type: Journal Article
This study aims to find a proper fertilization method to optimize nutrient requirements and a proper fertilization strategy through determining the amount as well as the period of fertilizers addition, with an aim of ...
Genotype by environment interaction and genetic heterogeneity of environmental variance of body weight at harvest in genetically improved farmed tilapia (Oreochromis niloticus) reared in 3 different countries
Type: Journal Article
Establishing breeding programs that improve farmed fish performance across multiple environments is crucial in a globalized aquaculture market. The main objectives of the current study were to assess the growth performance ...
Evaluation of production performance and profitability of hybrid red tilapia and genetically improved farmed tilapia (GIFT) strains in the carbon/nitrogen controlled periphyton-based (C/N- CP) on-farm prawn culture system in Bangladesh
Type: Journal Article
Bangladesh is one of the most suitable countries in the world for freshwater prawn farming because of its subtropical climate and vast water resources favoring an ideal condition for prawn production. Several recent ...
Transforming aquaculture in Cambodia through introduction of improved tilapia
Type: Brief
Aquaculture production in Cambodia has grown by an average 20% per year over the past decade according to official statistics, increasing from less than 50,000 metric tons in 2008 to 207,443 metric tons in 2017. The National ...

Some heavy metals concentrations in water and tilapia (Oreochromis Niloticus) muscles of fish farms supplied by three different water sources
Type: Journal Article
This study was conducted to assess and compare heavy metals contamination in muscle tissues (edible part) of fish cultured in ponds received fresh, agriculture and sewage drainage water which could poses a threat to human ...
WorldFish in Bangladesh
Type: Brief
Since 1989, WorldFish has been working with the Bangladesh Government and development partners to create a more productive fisheries and aquaculture sector that contributes to diversified and resilient rural livelihoods ...
Quantifying the genetic parameters of feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
Improving feed efficiency in fish is crucial at the economic, social and environmental levels with respect to developing a more sustainable aquaculture. The important contribution of genetic improvement to achieve this ...
Detection of Tilapia Lake Virus in Egyptian fish farms experiencing high mortalities in 2015
Type: Journal Article
The aim of this study was to detect potential pathogens in diseased tilapia that might account for the high summer mortalities observed in Egyptian fish farms. To this end, diseased fish were examined from eight farms in ...
