The state of aquaculture genomics

Major progress has been made in aquaculture genomics including genetic linkage maps, physical maps, microarrays, SNP arrays, and transcriptome and genome sequencing. Reference and draft genome sequences have been produced for dozens of fish and shellfish aquaculture species. This article will focus on aquaculture genomics using catfish mostly to demonstrate the processes rather than a thorough review of genomic resources for all aquaculture species. After the whole genome sequencing, the research community should focus on aquaculture performance and production traits, take advantage of the unprecedented genome information and technology, and make real progress toward genetic improvements of aquaculture brood stocks.
