Etude des composés soufrés d’intérêt planétologique : application aux atmosphères riches en CO2. - M. Lepère
This research focuses on sulfur compounds present in planetary atmospheres rich in CO2. The closest planets to Earth, Venus and Mars, have atmospheres composed of CO2 (95-96%). Romain will perform spectroscopic measurements required for data (concentrations, temperature ...) planetary atmosphere retrievials, by two high resolution spectroscopy techniques. One is the Fourier Transform Infrared spectroscopy (FTIR) in Reims and the second is IRis-F1, our high-resolution mid-infrared dual-comb spectroscopy. The line parameters obtained in this way will be essential for upcoming planetary exploration missions—particularly the ESA EnVision mission to Venus, which requires precise spectroscopic data under Venus-like conditions.

Valorization of the medicinal and agroecological potential of natural extracts in northern Vietnam - P. Kestemont
Among the countries of Southeast Asia, Vietnam is probably home to one of the richest repertoires of tropical biota, both in terms of plants and micro-organisms. Traditional medicine uses local plants, but the vast majority of biological activities that may be hidden in this environment are still unknown and the economic exploitation of this natural wealth is not yet effective in northern Vietnam, leading in part to poor economic 
development and low incomes, particularly in remote rural and mountainous areas. The proposed project will significantly strengthen the capacity of UNV's research groups to study the bioactivities and socio-economic potential of natural products for therapeutic purposes and as food supplements for animals and/or humans.

The overall objective of this project is to contribute to the sustainability of the fish sector in Vietnam through a better adaptation of fish farming. More specifically, the project aims to develop the capacities for the profitable development of euryhaline indigenous fish production in the Mekong Delta. To achieve this, it will develop husbandry techniques (R1), provide institutional stakeholders with a comprehensive feasibility as a decision-making tool (R2), provide producers with relevant knowledge and know-how (R3) and build research capacities (R4).

FEAMP smolts: Rehabilitation of Atlantic salmon in the Mosan basin in the context of rising water temperatures in a context of climate change - P. Kestemont & A. Erraud
The Walloon Region and the European Maritime, Fisheries and Aquaculture Fund (EMFAF / FEAMP) co-finance a three-year project to rehabilitate Atlantic salmon in the Belgian Meuse in a context of climate change. The influence of an increase in water temperature, based on the estimates of the 
Intergovernmental Panel on Climate Change (IPCC), on the production of stocked salmon, the fitness of smolts released and the early maturation of male parr will be assessed using a dual laboratory/field approach in tight collaboration with Cosmos salmon farming stakeholders. (2024-2027)

Adelante 2 - Triangular cooperation EU-LAC: Contribution to the development of herbal medicine - P. Kestemont
This Triangular Cooperation Initiative aims to harness the knowledge of the provider entities of the Partnership in the scientific research of natural products and crop production in controlled environments, in order to create a model for the development of herbal medicine. The University of Antwerp - UA (Belgium) and the University of Namur - UNamur (Belgium) have extensive experience in scientific research on natural products for pharmacological use, having developed innovative techniques for the analysis and characterisation of medicinal plants and other biological products for the development of medicines of natural origin.

IRP (International Research Partnership) with University of Lorraine - P. Kestemont
The aim of the project is to understand the effects of domestication on the reproduction and welfare of new species in aquaculture. The chosen model is the Zebra Fish. The fish will arrive from Bangladesh and will be in the wild. But we don't eat Zebra Fish, do we? So, why was this model chosen? First of all, because their genome is well known and a lot of bibliographic resources are available. Then, it is a species which reproduces quickly (a few months are enough to obtain a new generation). This enables to quickly analyze its resistance to stress and its reproduction in captivity. It should also be noted that the study plans to let the fish develop without making any selection, as is generally the case in farms. In this way, we can see whether domestication syndromes appear naturally, including phenotypic changes (appearance, morphology, levels of the stress hormone called cortisol, etc.).

The Geul River has an undeniable potential for restocking Atlantic salmon due to physico-chemical quality, habitat availability and abundance of suitable prey. The success of the reintroduction efforts is assessed by evaluating the growth rate, the fitness and the Catch Per Unit Effort of the fry restocked. The restocking of Atlantic salmon in the Geul River was an obvious success. The growth rate of the fry is one of the highest observed during the Meuse Salmon project.

Fish species are adapted to their natural environment and show light preferences even when raised in aquaculture. The hormone melatonin regulates many biological pathways such as sleep-wake timing or seasonal reproduction. Investigating melatonin under stressful light conditions will help to understand the mechanisms involved in its potential immuno-modulatory role.

PATHOFLAX - Développement de stratégies vertes de contrôle des pathogènes du lin - P. Van Cutsem, G. Van Aubel
The project aims at developing an integrated control against pathogens of common flax, more particularly against Verticillium dahliae, the fungus causing verticillium wilt. Flax cultivation, especially that of fibre flax, recently experiences massive revival in our regions. Biocomposite materials with long cellulose fibres provide flexibility, lightness and strength to an amazing diversity of marketable objects – see here for examples provided by one of the project partners: Terre de lin.However, verticillium wilt makes fibres brittle and fragile and no effective chemical control exists against this fungus. It produces micro-sclerotia, structures that can survive in the soil for many years. Together with the spin off FytoFend, URBV will investigate the effectiveness of the stimulation of plant defences (elicitors) to control the development of this disease.(2019-2022)
