Selective breeding can promote climate resilience  , and operations have already intentionally, or unintentionally, selected for production traits for changing conditions . Exposure of broodstock to future climate conditions may or may not confer advantages to offspring  . Traditional pedigree developments require extensive phenotypic data, but genomic selections can rapidly select for robust climate-associated traits . Genomic resources are available for salmon, rainbow trout, coho, carp, tilapia, seabass, bream, turbot, flounder, catfish, yellow drum, scallops, oysters and shrimp, but have been developed for disease and growth selections rather than climate resistance , although bivalve selections for ocean acidification and warming resiliency are underway . Targeted genome editing could modify phenotypes of major aquaculture species , but uptake is dependent upon national regulatory and public approvals. Local adaptations within species with higher climate resiliencies may assist in selections , but highlight the need to consider specific farming environments for selective processes . Projections of climate on aquaculture production traits are not well understood ; therefore, genetic diversity needs to be maintained to ensure population fitness  .
