General information

The BMB WG 30 was established by the BMB Committee at its annual meeting in Mariehamn, Åland Islands, Finland at 18-20 October, 1994. An initial meeting of the Working Group was held at the Faculty for Nature Sciences, Klaipeda University (Klaipeda, Lithuania) at June 5-9. The meeting was attended by 22 marine and freshwater biologists from Estonia, Germany, Finland, Latvia, Lithuania, Poland, Russia and Sweden; also specialists in Information Technology and Computer Sciences of Klaipeda University oined the WG 30 meeting. Materials of the meeting include: a report, format and technical notes on an encyclopaedia on the Baltic NEMOs recommendations to HELCOM, agenda, list of participants/WG members. Other relevant documents (list of the introduced species extracted from a Swedish report (Jansson 1994) ; ICES Code of Practice; ICES WGITMO National Report format; and IMO Voluntary Guidelines) are also enclosed.

1. Exchange of Information on Introduced Species.

Standardisation of entries into a Multimedia Encyclopaedia on the Baltic Sea Region NEMO's.
A Multimedia (Computerised) Encyclopaedia on the Baltic Sea Region NEMOs is to be one of the end products of the WG 30. It should include the follow up of introduced species, including bacteria, protozoans, fungi, parasites and disease agents.
Entries to the Encyclopaedia should be mailed to the Centre for Information Technologies and Environmental Studies in Klaipeda.
A printout of the Encyclopaedia will be sent to the WG Members for corrections and additions before the CD-ROM is produced.

Inventory of existing databases.
The Members of the WG 30 are encouraged to make an inventory of existing databases in their home countries. Information from these databases about introduced species should be extracted and sent to Klaipeda, using the standardised format. The database should be completed by information of the ICES WGITMO national reports. It is suggested that members of the WG 30 could serve as "corresponding members" to the ICES WGITMO to achieve a better geographic coverage for these reports.

Exchange of ballast water experiences.
To facilitate the start of ballast studies in other Baltic countries, the German project (contact person Stephan Gollasch) is willing to assist with information on sampling methods etc. This could also enable comparisons of results between different investigations.

2. List of Potential Invaders.

Shipping statistics.
Major shipping routes have to be identified, and preferably the volumes of discharged ballast water should also be listed for different areas of origin. These data are also asked for by the IMO. Since introductions from the Black Sea and Caspian Sea area are of special concern, it is important to get an estimate of the number of ships involved in river-going traffic. Data are completely lacking, but may be available through the customs offices and/or Department of Transportation of the respective countries.

Risk assessment.
- Hot spot areas.
Parallel to this work the WG should try to identify world-wide hot spot areas for possible new introductions to the Baltic Sea: areas that probably have comparable abiotic conditions (e.g. the Black Sea, Great Lakes and estuaries such as Chesapeake Bay). In addition to this the WG should try to locate critical areas in the Baltic Sea that may be sensitive to introductions.
- Hot spot organisms/"black list".
The WG 30 should investigate hot spot organisms already known to be invasive and/or harmful in other areas that are comparable to the Baltic Sea with respect to salinity etc. (organisms such as Mnemiopsis leidyi). Criteria are needed for classification of potential invaders into the following groups, like:

  • black (high risk species): e.g. hosts of parasites of man and wildlife, toxin producing organisms;
  • grey (medium risk species): e.g. fouling on ships etc;
  • white/beneficial (low risk species): e.g. no spread beyond the point of introduction, no observed or predicted impacts on the ecosystem.

For evaluating the potential of an organism to become an invader firstly abiotic criteria and secondly biotic criteria (such as being an opportunistic/generalist species etc.) could be used (compare the SCOPE Programme "The ecology of biological invasions").
A list of hot spot organisms could be forwarded to scientists as well as to international/national agencies responsible for environmental protection, including monitoring and aquaculture. It should also be forwarded to organizations such as HELCOM.
Risk assessments should also be carried out at the ecosystem level to be able to evaluate whether stricter rules are required for the Baltic Sea concerning e.g. ballast water management.
The Baltic Sea as a donor area for introductions The BMB WG 30 recognises that the Baltic Sea might be a donor area for introductions into other parts of the world. The WG should try to identify species that might cause harm if transported elsewhere and forward this information to e.g. IMO and ICES.

3. Monitoring Programme.

Areas that are the most likely to receive introductions, such as harbours, are generally not part of the national monitoring programmes. Studies of harbour areas therefore have to be carried out.
Close contact should be maintained between taxonomic expertise and those performing the monitoring programmes. Monitoring programmes should include instructions on how to report such records to HELCOM and the national authorities. They should also be encouraged to supply records of new species to the BMB WG 30 and to ICES WGITMO.
Since most introduced species have been recorded in shallow waters it is especially important that these areas are included in the intercalibration exercises carried out by HELCOM, and that shallow water stations should also be a part of the Baltic Monitoring Programme. Observations and effects of introductions should be incorporated into the HELCOM Periodic Assessments (made every five years) as well as reported annually to HELCOM Environmental Data Bank.
Reports of monitoring data may sometimes include introduced species, which have not yet been recognised (e.g. Corophium multisetosum and C. lacustre have been determined as C. volutator when only the latter species was known to be present in the area). Therefore, all data have to be controlled/checked for possible mistakes in taxonomic identification.

4. Risk of Introducing Parasites and Disease Agents.

The BMB WG 30 should co-operate with the BMB WG on Parasites and Disease Agents and the responsible ICES WG. The BMB WG 30 should especially focus on introductions which are completing the life cycles (as hosts) of formerly introduced parasites. The veterinary authorities should also be made aware of this problem.

5. Recommendations from the BMB WG 30.

The WG agreed upon a statement being sent to HELCOM and IMO (see Appendix 2). Copies for information will be sent to BMB, ICES and the non-governmental organisations WWF, Coalition Clean Baltic (CCB), International Union for the Conservation of Nature (IUCN) and the national representatives within the relevant committees/WGs of HELCOM and IMO.

6. Education and training.

Marine biology/taxonomy.
BMB WG 30 should try to organise PhD courses relevant to introduced species combined with taxonomic identification. Prof. Erkki Leppäkoski agreed to send an application to NorFA before June 1, 1996. He is also compiling a list of ongoing PhD and M Sc projects concerning introduced species (deadline middle of August 1995).
The members of the WG are asked to encourage colleagues who teach under-graduate level courses to incorporate the subject of introductions into the curriculum. As an example, the WG could provide a list of some relevant papers for teachers.

Authorities responsible for maritime activities.
Information about the potential problems in connection with introductions should be part of the curriculum at maritime colleges, with emphasis on the ballast water issue and the IMO Voluntary Guidelines (see Appendix 6). The WG should bring this issue to their attention. Members of the WG may volunteer as lecturers, or video presentations (such as that by the U S Coast Guard) may be made available.
The WG member should encourage/assist in training of persons belonging to authorities/agencies (e.g. Coast Guard, harbour, customs and local/regional authorities responsible for environmental protection and permission of aquaculture).

7. Laws on Reducing Risks of Introductions.

In order to prevent new introductions, rather than combat existing ones, methods for reducing the risk of introduction should be applied. This may include laws and regulations, technical and operational solutions. For intentional introductions the ICES "Code of Practice on the introductions and transfers of marine organisms" (see Appendix 4) should be applied. For preventing unintentional introductions by ballast water and/or sediment discharges the IMO Voluntary Guidelines for ballast water management should be followed.
The BMB WG 30 members should try to collect and spread information about laws and regulations applicable in their respective countries for animals, plants and genetically modified organisms (GMOs). This may be achieved through encouraging students in environmental law to incorporate this in their projects. International conventions applicable to the Baltic Sea region should also be identified by the WG.

8. Information to General Public.

The BMB WG members are encouraged to spread information to the general public by:
a) posters and information sheets at public aquaria, museums etc., including also information material for school classes;
b) through popular scientific articles in newspapers (without not exaggerating the risks);
c) coast watch programmes (incl. search for "easily recognised introduced species" like Sargassum muticum, Dreissena polymorpha, Ondatra zibethica and barnacles);
d) signs/posters of the type "you can help to prevent introducing/ distributing new species" at marinas etc., by checking organisms on boats, not using live baits from other areas etc.;
e) the WG 30 may create another poster in order to inform about the possible consequences of introductions as a scenario/model (like for zebra mussels introduced into the Great Lakes).

9. Terms of Reference.

A joint meeting of the BMB WG 30 and the ICES WGITMO is planned preliminary for April 22.-26. 1996 at the Sea Fisheries Institute in Gdynia Poland.
The WG 30 decided to make their final report to the BMB Symposium to be held in 1999.
