Performance of Oreochromis niloticus and Oreochromis andersonii in controlled laboratory conditions in Zambia
Type: Journal Article
In the present study, two hatchery strains of Oreochromis niloticus and two of O. andersonii sourced from different hatcheries in Zambia were subjected to the same feeding and management regimes in a controlled indoor tank ...
A review of access and benefit-sharing measures and literature in key aquaculture-producing countries
Type: Journal Article
Countries increasingly use access and benefit-sharing laws as a tool for the conservation and sustainable use of biological resources and associated traditional knowledge. These laws generally require the recipient of ...
On-farm performance of genetically-improved rohu (Labeo rohita) in Bangladesh
Type: Journal Article
Introduction: Rohu (Labeo rohita Hamilton) is a globally significant aquaculture species for which genetically improved strains are increasingly available. In 2020, a multiplier population, comprised of highly–ranked ...
Growth, yield and profitability of genetically improved farmed tilapia (GIFT) and non-GIFT strains in Bangladesh
Type: Journal Article
On-farm performance of the genetically improved farmed tilapia (GIFT) strain in monoculture and polyculture ponds in Bangladesh was assessed using a stratified random sample of 213 GIFT and 256 non-GIFT farmers. The GIFT ...
Genomic Selection and Genome-wide Association Study for Feed-Efficiency Traits in a Farmed Nile Tilapia (Oreochromis niloticus) Population
Type: Journal Article
Nile tilapia is a key aquaculture species with one of the highest production volumes globally. Genetic improvement of feed efficiency via selective breeding is an important goal, and genomic selection may expedite this ...
Early selection to enhance genetic gain in a rohu (Labeo rohita) genetic improvement program
Type: Journal Article
Multiple-stage selection can, in certain circumstances, be adopted to enhance genetic gain in genetic improvement programs while avoiding the cost of assessing and maintaining all individuals for extended periods. The ...
On-farm participatory evaluation of feeding approaches used by farmers for tilapia (Oreochromis macrochir) production in northern Zambia
Type: Journal Article
This paper reports the first benchmarking of smallholder tilapia farming practices in rural northern Zambia, measuring fish growth, feed utilization and water quality parameters, using a participatory action research ...
Tilapia (Oreochromis niloticus) trait preferences by women and men farmers in Jessore and Mymensingh districts of Bangladesh
Type: Journal Article
Research reporting user trait preferences for fish, particularly in relation to guiding genetic improvement programs are rare, even in tilapia where demand for genetically improved fish has underpinned the expansion of ...
Genetic parameters for black spot disease (diplopstomiasis) caused by Uvulifer sp. infection in Nile tilapia (Oreochromis niloticus L.)
Type: Journal Article
Black spot disease (diplopstomiasis), an external melanized host inflammatory response caused by a number of digenetic trematode parasites, results in slow growth, deformities and increased mortality among many freshwater ...
Genetic differentiation following recent domestication events: A study of farmed Nile tilapia (Oreochromis niloticus) populations
Type: Journal Article
Nile tilapia (Oreochromis niloticus) is among the most farmed finfish worldwide, distributed across different environmental conditions. Its wide distribution has mainly been facilitated by several breeding programs and ...
