Research Project: Quantitative Genetics Analyses and Genome-Wide Association Studies for Commercially Important Disease Resistance Traits in Rainbow Trout Aquaculture

Location: Cool and Cold Water Aquaculture Research

Project Number: 8082-31000-012-10-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2017
End Date: Aug 31, 2020

Objective:
To conduct quantitative genetics analyses and genome-wide association studies (GWAS) for commercially important disease resistance traits in rainbow trout aquaculture such as bacterial cold water disease (BCWD), columnaris disease (CD) and infectious hematopoietic necrosis (IHN).

Approach:
Large datasets of pedigrees, phenotypes and genotypes from the new rainbow trout 57K SNP chip are available for this project from the USDA-ARS-NCCCWA selective breeding program population and from commercial partners who are working closely with the NCCCWA. The PI from the University of Georgia will supervise a postdoctoral associate in conducting quantitative genetics analyses and genome-wide association studies (GWAS) for commercially important disease resistance traits in rainbow trout aquaculture such as bacterial cold water disease (BCWD), columnaris disease (CD) and infectious hematopoietic necrosis (IHN). In addition, The University of Georgia PI and other members of the animal breeding, genetics and genomics team at the University of Georgia will work on developing refined genomic selection models for salmonids aquaculture using real genotype/phenotype data relevant to rainbow trout aquaculture and taking advantage of the emerging rainbow trout genome resources from research conducted at the NCCCWA.
