Report of the Working Group on Introductions and Transfers of Marine Organisms (WGITMO) [By Correspondence]

because other ICES WGs such as the WG on Application of Genetics in Fisheries and Mariculture will have the necessary expertise and may have put thought into the genetics aspects of introductions and transfers and invasive species issues we suggest a closer linkage and possible invitation of a geneticist to next year's meeting. Conclusions WGITMO will intersessionally draft a document relevant to this ToR.WGITMO members will intersessionally collect relevant information for consideration at next years meeting. WGITMO suggest ICES to consider initiating the contact to the other relevant WGs by putting the topic into their terms of reference to interact with WGITMO to strengthen the Code. Recommendations WGITMO recommends to deal with this ToR at next years meeting.WGITMO proposes to update the existing risk assessment approach in the Code of Practice at next year's meeting and to facilitate the discussions by intersessionally work. Summary of National Reports 1984-2004 (ToR C)The group discussed this ToR in great detail and believes that it cannot deliver maps with organism densities as the information provided in National Reports is too scattered.However, WGITMO suggests to deal with certain species frequently having been moved between ICES Member Countries in greater depth likely resulting in reports similar to the Species Alert Reports as delivered on the Rapana Whelk and Red King Crab.At last years meeting, WGITMO was given the ToR to summarize the National Reports received for the period 1992-2002 in a similar fashion as the National Report summary 1981-1991.WGITMO took the earlier summary of National Reports as a guiding document, but agreed to restructure its approach for the 1992-2002 summary (see last years meeting report).Summary material was prepared intersessionally and circulated for consideration at this years meeting.Certain group members have started to compile the information.Inger Wallentinus (Sweden) focuses on algae, Dan Minchin (Ireland) on fish and Chad Hewitt (New Zealand) and Stephan Gollasch (Germany) dealt with invertebrates.WGITMO discussed including a viruses and pathogens section which Dorothee Kieser (Canada) had volunteered to cover.However, given that other ICES WG are covering the diseases and disease agent distribution and related topics, it was decided to limit WGITMO's topics to fish, invertebrates and algae.Having received the group's comments the volunteers will prepare intersessionally a final draft document until next years meeting.Therefore the group felt that this ToR should be kept on the Agenda of WGITMO.To support the REGNS integrated assessment WGITMO prepared a summary of non-native species known to occur in the North Sea.The list contains intentionally introduced species and accidental introductions (Annex 6).A number of species were selected to be covered in a more detailed format during an earlier EU-funded study.These case histories of impacting invaders have been included as Annex for the consideration of REGNS (Annex 7). Conclusions It was agreed by WGITMO that intersessional activities are essential to finalize this ToR at next years meeting.
