Performance evaluation of Nile tilapia (Oreochromis niloticus) improved strains in Ghana
Type: Journal Article
Growth performance and survival to harvest of the Akosombo strain generation 10 and the GIFT strain generation two (derived from GIFT generation 11 in Malaysia) were evaluated in Ghana. The fish were from 96 families of ...
Development and validation of an open access SNP array for 2 Nile Tilapia (Oreochromis Niloticus)
Type: Journal Article
Tilapia are amongst the most important farmed fish species worldwide, and are fundamental for the food security of many developing countries. Several genetically improved Nile tilapia (Oreochromis niloticus) strains exist, ...
Fluctuations in growth are heritable and a potential indicator of resilience in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Resilience can be defined as the capacity of an animal to be minimally affected by perturbations or to quickly recover to the state it had before the perturbation. When applied to production animals, resilience is defined ...
Genotype by environment interaction between aerated and non-aerated ponds and the impact of aeration on genetic parameters in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
A major problem in smallholder Nile tilapia (Oreochromis niloticus) farms is that the achieved production is much lower than under optimal management. One of the main environmental factors contributing to lower production ...
Growth performance of three strains of Nile tilapia (Oreochromis niloticus) on four different feeds in Western and Central Kenya
Type: Journal Article
The growth performance of three commercially available strains of Nile tilapia (Oreochromis niloticus) fed one of four different commercially available feeds during nursery and grow-out was assessed in Kenya. Each of the ...
Quantitative trait loci controlling swimming performance and their effect on growth in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Critical swimming speed (Ucrit) is an important measurement of swimming performance and a good indicator for cardio-respiratory health. It offers a new opportunity to select fish with better fitness. However, the genomic ...
Genome-wide association analysis of adaptation to oxygen stress in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Background: Tilapia is one of the most abundant species in aquaculture. Hypoxia is known to depress growth rate, but the genetic mechanism by which this occurs is unknown. In this study, two groups consisting of 3140 fish ...
Molecular characterization, virulence profiling, antibiotic susceptibility, and scanning electron microscopy of Flavobacterium columnare isolates retrieved from Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Columnaris is a common flavobacterial disease affecting tilapia aquaculture. Flavobacterium columnare has been identified as being responsible for the heavy mortalities of earthen-pond-cultured Nile tilapia (Oreochromis ...
Key risk factors, farming practices and economic losses associated with tilapia mortality in Egypt
Type: Journal Article
Egypt is the topmost aquaculture producer in Africa and the third largest tilapia producer globally. Nile tilapia in particular is the cornerstone of fish farming in Egypt. Recently, fish farms have experienced unusual ...
Genetic parameters for resistance to Tilapia Lake Virus (TiLV) in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Tilapia Lake Virus (TiLV) is one of the primary disease concerns for tilapia farming, with mass mortality events and biosecurity restrictions threating aquaculture in several continents. Selective breeding for improved ...
