Fish Conservation

FISH CONSERVATION DIVISION

Objective: Development of tools, resources and information on aquatic genetic material for conservation research and applications

Thrust Areas:

  • Conservation genetics and genomics: Documenting inter- & intra-specific genetic variation & genetic stocks & genomic resources
  • In situ conservation: Germplasm exploration, status & utilization, people's participation approach
  • Ex situ conservation: Live gene bank & artificial propagation for prioritized species; establishment of repositories; cryopreservation of sperm/embryonic cells; germplasm registration and IPR
  • Human resource development.

Salient Achievements:

  • Explored river basins viz., Indus, Ganga, Ghagghar, Brahmaputra, Mahanadi, Krishna, Godavari and their tributaries to collect the fish accessions for taxonomic validation, stock identification and repository
  • Sixteen fish and shellfish species studied for their population genetic structure using molecular markers across the natural range of distribution in Indian rivers
  • Taxonomic validation done for Indian mahseers using molecular markers
  • Microsatellite enriched genomic library constructed for Chitala chitala and Pangasius pangasius
  • Type I Markers developed in Clarias batrachus EST-SSR (221); SNPs (33); ESTs (1923) and genes related to immune response (24)
  • DcDNA libraries of 6 tissues developed for Clarias batrachus
  • Complete mitochondrial genome of Clarias batrachus and Pangasius pangasius sequenced
  • A total number of 33 fish species have been characterized at species level using different molecular markers and polymorphic microsatellite DNA markers identified for 30 fish species
  • Genes with differential expression identified for hypoxia tolerance in Clarias batrachus
  • Sperm cryopreservation protocol developed for 26 fish species & tested with production of viable hatchlings for 18 fish species
  • Tissue bank established with over 13,000 accessions
  • Established Live Gene Bank at Lucknow and Guwahati
  • The innovative approach of ICAR-NBFGR inviting Sate Govt. to declare one fish as state fish, received enthusiastic response with 16 states already declared/accepted state fish
  • Embryonic stem cell line developed for Indian catfish, Heteropneustes fossilis
  • Documented role and potential of fisher folk institutions in sustainable management and conservation of fishery resources
  • Efforts initiated to focus indigenous knowledge documentation for access benefit sharing.
