GENOMIC SELECTION IN CATFISH: A REVIEW

Abstract

Aquaculture genomics identifies the genetic basis of performance and production traits and utilizes such information for selective breeding programs. Fisheries genomics, an emerging field that applies genomic tools to solve questions related to fisheries management, has been discussed less frequently as compared to aquaculture genomics. Genes specific to important environmental and terrestrial adaptation, locomotion, immune system, anti-microbial properties, thermoregulation, air-breathing, etc. were identified and critically analysed. The analysis clearly indicated that Catfish genome possessed several unique and duplicate genes similar to that of terrestrial or amphibians’ counterparts in comparison to other teleostean species. The genome information will be useful in conservation genetics, not only for this species but will also be very helpful in such studies in other fishes.
