  • Estimate of wild caught fisheries production
    2003-2004
  • (US) 360 million
  • Source ABARE
  • Level of expenditure on recreational fishing
    1999-2000
  • (US) 1360 million
  • Source ABARE

Estimated 4,500 species finfish (3,600
described) 25 endemic to Australian waters

  • Progress so far

Sequenced 1172 specimens for 655bp region of COI
( 283 species, 138 genera) 954 specimens (237
species) put into BoLD Remaining unentered data
will be put into BoLD in June 2005

Barcoding Australian Fish
Pairwise distance among members of different
taxonomic levels

Pairwise distance Kimura 2 parameter
725 sequences/individuals, 165 described species
(each with two or more individuals) 44 genera
(teleosts and elasmobranchs)
11
COI neighbour-joining tree of 206 fish species
and 754 sequences

Representative tree output from BoLD

  • Tuna Identification

Tuna identification
15
Identification of shark fins
  • Large amounts of illegal capture of sharks in
    northern Australian waters, largely for fins
    alone
  • Quality fins sell for as much as 6 000 - 8 000
    / kg in Hong Kong.
  • Globally, gt100 million sharks killed per year
  • Slow growing, long lived, long gestation, low
    fecundity.
  • Many species morphologically very similar, and
    many are protected.

16
Fish fillet identification
17
Egg identification
Positive ID sequencing of COI confirms
identification of eggs/larvae as blue mackerel
1.05 1.30mm diameter
18
Future work
  • Complete barcoding of Australian fish
  • Commercial species
  • Non-commercial species
  • Link with CAML (Census of Antarctic Marine Life)
