2018-2022. DIVERTHYM : Aquaculture diversification in Wallonia: improvement of grayling (Thymallus thymallus) rearing techniques for high value food fish production (convention SPW DGO3 - FEAMP 47-1703-004).Read more...

The aim of this project, promoted by the CEFRA-ULiege, is to meet the need for product diversification in Walloon fish farming. The target species is the grayling (Thymallus thymallus), a high-value food fish.

Researches focus on the development and improvement of the breeding practices. As a partner, CERER-Pisciculture is responsible for information dissemination and scientific popularization.

The project is structured in 5 points :

1. Optimization of  zootechnical parameters for survival and growth improvement at larval, juvenile and adult stages.

2. Assessment of growth and production  potential under a natural temperature regime and in a recirculated system with controlled temperature.

3. Photo-thermal control of sexual maturity and reproduction  and improvement of post-spawning breeder survival.

4. Identification and control of pathologies.

5. Sharing of zootechnical information with fish farmers and assessment of production costs.
