    Improvements of the methodology in fish tagging techniques with emphasis on the application in fisheries research and stock assessment.




    As this project is a Concerted Action, it must achieve its goals by meetings, workshops, exchange of information and facilitation of communication between researchers. The project works towards these objectives by collecting and collating information, discussing new ideas and making recommendations for improved procedures and further research and development.


    The work is achieved by:


    The main deliverables will be:

    The web-site will include information for designing surveys, manuals of tagging methods (in database format), a tagging bibliography, lists of manufacturers of tags and tagging equipment (with access to the manufacturer’s web-site, where possible), an on-line conference section, and information on the project and participants.



    Four work-groups were formed at the beginning of the first meeting. Their purpose was to work on different aspects of the CA. The work-groups have been active during the project time in between meetings communicating over the WWW.


  • Group A, dealing with conventional tagging (ID tags)

    Chairman: Curt Insulander,

    Others: Dr. Stig S. Pedersen, Mrs. Josianne St°ttrup, Mr. Vilhjalmur Thorsteinsson

    Group B, dealing with electronic tagging, telemetry and data logging tags

    Chairman: Dr. Geoff Arnold.

    Others: Mr. Sigmar Gudbjornsson, Dr. Tor G. Heggberget, Mr. Johannes Sturlausson,

    Dr. Niall Ë MaoilÚidigh, Mrs. Marianne Holm.

    Group C, dealing with general fish health and behavior change encountered in tagging

    procedures and legislation which affect tagging

    Chairman: Prof. John Davenport.

    Others: Dr. Gianna Fabi, Dr. Etienne Baras, Dr. Gisli Jonsson.

    Group D, dealing with data analysis and modeling

    Chairman: Dr. Olav R. God°.

    Others: Federico Borghini, Mr. Tapani Pakarinen, Dr. George Tserpes.

  • The work-groups work mainly at General-meetings where the time is divided between general sessions and work group activity. The work is continued between meetings by communication over the WWW. The information is drawn from experiences of partners short inquiries or surveys and literature surveys.



    The first overall survey effort has been partitioned into smaller ones which address:





    Meetings held in the first half of the project period


    The Web-site

    Organization of a web-site for communication and dissemination of results.

    The organization and construction of the web-site was one of the main activities of the coordinator in 1997. The CATAG Web-site is used as an activity site, an instrument for the implementation of objectives and as a medium for displaying of the project’s deliverables. It will be in construction during the project period.

    The various outputs of the Work-group activity will gradually became functions under the CATAG Web-site tools for improving the methodology of tagging experiments and these will also be documented in the final reports.

    If successful, the CATAG Web-site will be very useful after the CA project is finished as a tool for researchers who use tagging experiments or are involved in tagging projects anywhere in the world and for those who are interested in this kind of work like many fishermen are.



    Progress of the CATAG Web-site

    This web-site is still under construction but active and can be accessed on the WWW under ><.

    The CATAG Web-site is in several sections and subsections most of which are open to general public but 2 options of 14 are accessible only by passwords because they are working areas for partners.


    The following options are on the first or central page of the CATAG Web-site.

    Background: Background information on the project. For further information on the CA project and its objectives tasks there is a link to the Technical Annex of the CA-project.

    CATAG progress reports: This option will open a list of reports from where there are links to full text reports of the project activities.

    Legislation: This option presents the outcome of a search which was carried out by the working group on health and legislation. This has entries of the legislation that applies to tagging in European countries.

    Producers and suppliers of tags: This option opens a list of all known producers of tags and tagging equipment with access (links) to their web-sites if they have one. This part has been active since September 1997. Some producers have already illustrated catalogs and ordering forms on their linked web-sites.

    Project participants: This option leads to a list of participating institutes and the representatives of these institutes or SMEs. Name of each representative has (or can have) a link to personal home pages of theirs. Each name of an institute has also links to its home-pages for further information.

    References in tagging (not finished): This option will open a list of Databases with references on various kinds of tagging.

    Surveys (not finished): This part is being developed as a tool for conducting surveys over the WWW.

    Tagging methods (not finished): This option will open a list of On-line manuals of tagging procedures.

    Tags released: This option opens up a tool which can, for instance, help to trace a tag to the institute which released it. Here it is also possible to get information, such as, how many fish have been released by a certain institute. This section is open and active but so far only one institute (MRI) is connected.

    Various links: This option opens a list of various links which could be useful but do not fit in with other material of the web-site(open and active).

    Work-groups: This option opens a page with information about the work-groups such as: the objectives and tasks of each group, the participants in each group, how to get messages to the groups, etc.

    Conference board: This option has facilities for conferencing on the home-page. At this stage it is open and active but accessible only by password.

    Work area: This option opens a special work area for the participants. It includes information and unfinished reports which are still being edited and scrutinized by the partners.





    General meeting + management committee meeting in Ancona in October 1998.

    Management committee meeting in Dublin Ireland in January 1999.

    In stead of another general meeting after the one in Ancona the plan is to have at least one meeting per each work-group in the period, November 1998 to May 1999, as needed to finish the various tasks of the project. This may depend on the financial status of the project.


    Literature surveys by each work-group to continue as needed. The resulting information to be attached to appropriate places on the CATAG Web-site by October 1998.

    Surveys to research institutes in Europe, will be carried out by September 1998. Will serve to get further information, make contacts with researchers, introduction of researchers in tagging work to the use of the CATAG Web-site.

    CATAG Web-site

    All sections of the Web-site need to be worked on during the project period.

    Databases on tags, tagging methods, references to articles on tagging, finished and search-able, by November 1998.


    A contract should be drawn up, on how the CATAG web-site should be run after May 31st, 1999. The MRI offers to take over the running of the CATAG web-site after the project period is finished, if and when a contract is in place which is agreed on by the participating institutes of the CATAG and European Community.


    Final outputs and deliverables finished by May 1999.

    Final reports and output will have three forms: One is a report which is in the format which is decided by the EC. The second will be a publication in the series of the proceedings of the MRI and the third will be the CATAG web-site with all the tools and databases. Conclusions and Recommendations of the CA project and Recommended projects which could be worked on and applied for to the EC.
