Genomic architecture of selection for adaptation to challenging environments in aquaculture
Type: Thesis
Aquaculture, including freshwater and marine farming, has been important for global fish production during the past few decades. However, climate change presents a major risk threatening both quality and quantity of ...
Population, temperature and feeding rate effects on individual feed efficiency in European Sea Bass (Dicentrarchus labrax)
Type: Journal Article
Using breeding programs to improve feed efficiency, the ratio between fish body weight gain (BWG) and feed intake (FI), could increase aquaculture sustainability through reduced feed costs and environmental impact. To this ...
Variations in isotope incorporation rates and trophic discrimination factors of carbon and nitrogen stable isotopes in scales from three European sea bass (Dicentrarchus labrax) populations
Type: Journal Article
Carbon (δ13C) and nitrogen (δ15N) stable isotope analyses are used in marine ecology to study trophic relationships and migrations of species since they reflect dietary sources consumed which may vary geographically. ...
Cell wall disruption: An effective strategy to improve the nutritive quality of microalgae in African catfish (Clarias gariepinus)
Type: Journal Article
The rigid cell walls of microalgae may hinder their utilization in fish feeds. The current experiment assessed the correlation between the accessibility of microalgae nutri- ents and their in vivo digestibility in African ...
Sustainable and accessible fish feeds for small-scale fish farmers
Type: Brief
Improving feed accessibility for small-scale fish farmers is crucial to the inclusive growth of aquaculture. “Nutritious pond feeds” nourish the farmed fish and the pond organisms that help break down fish wastes and produce ...
Closing the yield gap: improving production efficiency in smallholder farms of Nile tilapia through selective breeding
Type: Thesis
The aim of this thesis was to optimise the breeding program of Nile tilapia for a smallholder production system, thereby contributing to closing the yield gap. From Chapter 2 to 4, we generated information that can be used ...
Cell wall disruption increases bioavailability of Nannochloropsis gaditana nutrients for juvenile Nile tilapia (Oreochromis niloticus)
Type: Journal Article
In this study the correlation between the accessibility of nutrients and in vivo nutrient digestibility was tested on the marine microalga Nannochloropsis gaditana in juvenile Nile tilapia (Oreochromis niloticus). It was ...
