Trials to improve the response of Orechromis niloticus to Aeromonas hydrophila vaccine using immunostimulants (garlic, Echinacea) and probiotics (Organic Green and Vet-Yeast)
Type: Journal Article
Aquaculture is a promising sector of fish industry in the world with about 80 million tones being produced annually. The development of aquaculture faced several constraints; among these are diseases constituting the ...
Genetic parameters and correlated responses in female reproductive traits in the GIFT strain
Type: Journal Article
The aim of this study was to examine genetic variation in reproductive traits and to estimate correlated responses in such traits to selection for high growth rate in the GIFT strain of Nile tilapia (Oreochromis niloticus).
Genetic variance for uniformity of harvest weight in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Competition for resources is common in aquaculture, which inflates the variability of fish body weight. Selective breeding is one of the effective approaches that may enable a reduction of size variability (or increase in ...
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 ...
Genetic and non-genetic indirect effects for harvest weight in the GIFT strain of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
The main objective of this study was to quantify the heritable variation for growth rate of GIFT, and the contribution of IGEs to this heritable variation. Here we describe the experiment conducted for this purpose, and ...
Increasing fish farm profitability through aquaculture best management practice training in Egypt
Type: Journal Article
Egyptian aquaculture production has grown rapidly to over one million tons per year so that it now provides most of the countrys fish supply. However, Egyptian fish farmers have received little extension advice or training. ...
