5Rationale for FISH-BOL
- Fish comprise nearly half of all vertebrates, yet
with 30,000 described species they are still a
manageable group for demonstrating the utility of
barcoding. - As the dominant source of protein in the human
diet and with an estimated 200 billion USD
annual value of fisheries worldwide, fishes are
of major socio-economic importance. - With 300,000 names recorded for fishes world
wide, harmonization of names across collections
is needed. - Challenge establish an organizational
infrastructure with clear sampling and analytical
protocols.

Inaugural Fish Barcode of Life Workshop, 5-8
June 2005
7FISH-BOL takes shape
- Goal
- Coordinate the assembly of a reference sequence
library for all fish species.
8Existing collections and anticipated sampling
effort
- About 33 million fish specimens reside in museum
collections their barcode analysis will
ultimately aid both the resolution of cases of
synonymy and help define species concepts. - The fixation of these specimens in formalin has
led to DNA damage that makes sequencing
difficult. - Serious effort needs to be directed to the
collection of fresh specimens to ensure rapid
progress. - Plans call for the initial analysis of 5
specimens of each species from each major
biogeographic region.
9Barcode Acquisition
- It will be necessary to analyze some 0.5M fishes
to assemble a barcode library that provides
adequate geographic coverage for the estimated
30,000 species of fishes. - Analytical protocols are in place and costs are
currently about 5 per specimen. - Because of the volume of samples and expense of
capillary sequencers, it is expected that much of
the DNA sequencing will be done in large-scale
facilities.
10Barcode Repository and Analysis
- The FISH-BOL initiative is assembling specimen
records that encompass both a DNA barcode
sequence and the provenance data associated with
the specimen examined. - The Barcode of Life Data (BOLD) System
(www.barcodinglife.org) provides a web-based
platform used for the assembly and analysis of
these records. - All of the sequence records and elements of the
specimen data will subsequently migrate to
GenBank and the other major genomics repositories
upon publication of results.
11Organizational Structure
- The FISH-BOL campaign consists of individual
projects coordinated by regional working groups
that target FAO areas. - There 10 of these regional groups, each is
working to assemble and analyze fish samples from
its region. - Scientific interest will derive from comparisons
that span continents and oceans, collaborations
that will be fostered by the campaign.

Is it time for taxonomy to break with tradition
and unify on the Internet?
13Methods
14Digital Characterization
- e-Vouchers
- Enhance access to collections
- Reduce wear on specimens
- Document identity when no morphological voucher
exists
15Detailed View

Macrouridae rattails, grenadiers
Coryphaenoides 12 species of grenadier in the New Zealand EEZ
Coryphaenoides subserrulatus Four rayed grenadier
Coryphaenoides striaturus Striate grenadier

18Voucher Specimen Labeling is Critical
- Specimen labels
- DNA barcode labels needed on vouchers (genetic
epitypes). - important for bidirectional linkage between
barcode records museum collections.

30Expected Benefits
- Standardize the application of names.
- Facilitate species identification for all users,
particularly in cases where traditional methods
are not applicable. - Highlight specimens that represent a range
expansion of known species. - Flag unrecognized or cryptic diversity.
- Demonstrate the value of collections and
taxonomists contributing to the campaign.
31 Summary
- As a tool for taxonomists, DNA barcoding and
FISH-BOL are pivotal for dealing with both
synonymy and species discovery. - The resulting registry of sequence accessions
will unite a diverse assemblage of specimens,
collections and species information. - It will also enable the rapid identification of
larval, fragmentary or otherwise ambiguous
samples for regulatory and other purposes.
