Title: A Plan to Barcode All Fishes

A Plan to Barcode All Fishes
  • CSIRO Marine Research, Hobart, Tasmania

2
Why barcode fish - 1
  • Although the largest vertebrate group (about 50
    of all vertebrate species), they have a
    manageable number of species
  • c. 20 000 marine (15 648 in Fish Base, 91 with
    subspecies)
  • c. 15 000 freshwater (13 544 in Fish Base, 152
    with subspecies)
  • (705 shared marine / freshwater species)
  • c. 80 brackish only (82 in Fish Base, 1 with
    subspecies)

  • (705 shared marine / freshwater species)
  • c. 80 brackish only (82 in Fish Base, 1 with
    subspecies)
  • Systematically very diverse
  • Superclass Agnatha (jawless fish)
  • Class Cyclostomata lampreys, hagfish
  • Subphylum Gnathostomata (jawed vertebrates)
  • Superclass Pisces (jawed fish)
  • Class Chondrichthyes cartilaginous fish -
    chimaerids, sharks, rays
  • Class Osteichthyes bony fish - coelacanths,
    lungfishes, eels, carps, tunas, salmons,
    flatfishes, sea horses etc

Why barcode fish - 2
  • Global value at first sale
  • Capture fisheries in 2000 c. US 81 billion
  • Aquaculture (excl. plants) in 2000 c. US 52
    billion
  • Ornamental fish
  • Retail trade in US alone in 2000 c. US 3
    billion
  • Sports fishing
  • In Australia in 1984, recreational fishers c.
    US 2 billion.

  • Fisheries activities globally generate trade gt
    US 200 billion
  • And employ 35 million people

Applications of Fish Barcoding
  • Identification of fish, fillets, fins, and
    fragments (marketing, substitutions, quota and
    bycatch management).

Applications of Fish Barcoding
  • Identification of fish, fillets, fins, and
    fragments (marketing, substitutions, quota and
    bycatch management).
  • Identification of processed product e.g. canned
    fish, dried fish, mixtures (substitutions).

16
What is needed?
  • Specimens
  • Relevant data per specimen
  • Storage and taxonomic facilities
  • Genetic facilities
  • Database
  • Organisation

17
What is needed for Fish-BOL?
  • Specimens
  • One or more tissue specimens per
    species/subspecies
  • Tissue samples not stored in formalin but in
    ethanol or frozen
  • Accurate records for each specimen
  • Use existing specimens where possible to reduce
    costs
  • Collect new specimens by piggy-backing on
    existing cruises/collecting
  • Consider a centralised tissue bank (at least per
    region)?

  • Relevant data per specimen
  • Species identity, GPS location (including depth),
    names of collector identifier, date of
    collection, storage location
  • Photograph of original specimen when possible

19
What is needed for Fish-BOL?
  • Storage and taxonomic facilities
  • Storage of tissues and whole animals until
    sequencing completed (where possible)
  • Storage of one or more voucher specimens per
    species (per region?)
  • Specimens to be identified by expert taxonomist
  • Undescribed species will require vouchers

  • Storage of one or more voucher specimens per
    species (per region?)
  • Specimens to be identified by expert taxonomist
  • Undescribed species will require vouchers
  • Genetic facilities
  • Sequencing will require access to automated
    sequencer
  • Samples can be sent to a central sequencing
    facility (within region?)
  • Each sample to be sequenced in both directions to
    get consensus sequence for database
  • Electropherograms retained
  • Each species to be represented by multiple
    specimens, preferably from different locations

21
What is needed for Fish-BOL?
  • Database
  • Publicly-accessible (at least for search /
    specimen identification)
  • Single database and a database manager
  • Data input and correction simple (locally, or by
    database manager?)
  • Outputs to include simple analyses and lists of
    species
  • Links with other databases especially FishBase
  • Probably will need to be mirrored in several
    locations
  • Common names standardised to FishBase common
    names?

  • Regional co-ordinators? What regions?
  • Database manager
  • Support funding

Marine fish species by FAO areas
  • Aim for 5 per species per FAO area?
  • Aim to get the 5 samples from diverse parts of
    the area (but marine
  • population differentiation ltlt freshwater
    population differentiation)

26
A Possible Structure
There are many other possibilities of course,
e.g. having co-ordinators for each FAO area,
separate Indian Ocean and Pacific Ocean
co-ordinators, or North Pacific and South/Central
Pacific.. Each FAO area has a list of species
which the co-ordinator would be responsible for
updating, eg. species collected, barcoding
status, database entry Need to avoid / minimise
duplication of effort within an area.
