Breeding and Genomics in Aquaculture

Breeding and Genomics in Aquaculture

Breeding to enhance fish growth, feed efficiency and animal health have been important factors contributing to the expanding role of terrestrial food systems in global aquaculture. Yet, genetic selection of fish and shellfish on just production aspects is not sufficient anymore. Today’s breeding also requires selection criteria for many less-easy-to-measure characteristics like animal health, environmental impact and fertility. We identify these genetic aspects in the performance of fish and shellfish, and develop optimal breeding schemes for selection. We integrate genomic and quantitative approaches to animal breeding.


Prof. Hans Komen and John Bastiaansen (ABG) are experts in genomic selection of finfish, with Mark Camara (WLR) having a strong additional interest in genomic selection of shellfish.


Whole-genome bioinformatics approaches by next generation sequencing assist functional analysis of fish genomes. Knowledge of genetic variation within and between fish species is crucial to an understanding of patterns of variation during evolution or domestication. The Animal Breeding and Genomics (ABG) and Aquaculture and Fisheries (AFI) groups of WUR join forces studying comparative genomics for fish health.
