摘要
Due to the availability of genomic resources,including whole genome sequences and numerous DNA markers in some aquaculture species,genetic improvement of important traits has since moved on from conventional breeding to marker-assisted and genomic selection,or a combination of both.However,phenotyping has become the major bottleneck,which hinders the genetic improvement of fish.Although some phenomics platforms have been developed for the precise,rapid and non-invasive measurement of important phenotypes(e.g.growth traits)in aquaculture species,the phenomics platforms for most traits(e.g.disease resistance,stress tolerance,behavior)are still lacking.Recent advances in novel technologies,including automated imaging/machine vision,diode frame measurements and deep learning networks,will provide solutions to the development of phenomics platforms,including phenotyping,data acquisition and processing.In this article,we describe the concept of phenomics and its importance in fish breeding.We also summarise the status and challenges in developing phenomics platforms in aquaculture and propose suggestions in the development of these phenomics platforms.
