High-throughput phenotyping of health biomarkers in Crassostrea gigas by magnetic resonance imaging
High-throughput phenotyping of shellfish’s traits constitutes a challenge due to the specificities of aquatic animals. Appropriate measuring tools have often to be developed or adapted, in order to continuously and automatically acquire data of biomarkers of interest. IMAGIGAS project aimed to explo...
