| One of the top priorities of the aquaculture industry is the genetic improvement of economically important traits in fish, such as those related to processing and quality. However, the accuracy of genetic evaluations has been hindered by a lack of data on such traits from a sufficiently large population of animals. The objectives of this study were thus threefold: (i) to estimate genetic parameters of growth-, yield-, and quality-related traits in rainbow trout (Oncorhynchus mykiss) using three different phenotyping technologies [invasive and non-invasive: microwave-based, digital image analysis, and magnetic resonance imaging (MRI)], (ii) to detect quantitative trait loci (QTLs) associated with these traits, and (iii) to identify candidate genes present... |

| 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 explore a non-destructive and non-invasive approach by using magnetic resonance imaging (MRI) to monitor at high-throughput two biomarkers (body weight and temperature) of the pacific oyster, before and during infectious challenges by Ostreid Herpesvirus type 1 (OsHV-1). Pacific oysters and OsHV-1 suspension and contaminated seawater were produced at Ifremer facilities. The experiments were conducted in 2016-2017 by three staffs (Ifremer LGPMM, Irstea IRM Food,... |
