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.
