208 NIS for aquaculture purposes. On the European level the EC Council Regulation No 708/2007 concerning the use of non-indigenous and locally absent species in aquaculture is based on the ICES Code of Practice. With the maritime activities segment of the Baltic Sea Action Plan HELCOM expresses the strategic goal to have maritime activities carried out in an environmental friendly way and that one of the management objectives is to reach “No introductions of alien species from ships”. In order to prepare the implementation of the Ballast Water Convention a road map has been established with the ultimate to ratify the BWM Convention by the HELCOM Contracting States preferably by 2010, but in all cases not later than 2013. The EU Marine Strategy Framework Directive in order to maintain or achieve good environmental status in the marine environment established a framework for Member states. The good environmental status shall be determined on the basis of qualitative descriptors. One of the qualitative descriptors concerns nonindigenous species stating ‘Non-indigenous species introduced by human activities are at levels that do not adversely alter the ecosystem.’ Biopollution Level index has been reviewed by the EU MSFD good environmental status task group 2 on non-indigenous species and is seen as a straight-forward and practical way of assessing impacts of the NIS and their potential to become invasive. BPL index is also viewed as a practical solution for the Ballast Water Management efforts to distinguish between species which pose a threat on regional voyages and which should therefore be taken into account in Risk Assessments done for IMO BWM Convention when considering if a certain ship route may get an exemption from ballast water treatment procedures. Biopollution Level assessment has presently been performed only once. Thus there are no temporal trends yet available concerning this indicator. Assessment This assessment is a baseline assessment, since the target for next assessments is to estimate impacts of new introduced species. Good Environmental Status is met when further impacts from NIS are minimized, with the ultimate goal of no adverse alterations to the ecosystems during the assessment period.The baseline assessment was performed for nine Baltic sub-regions. It revealed that documented ecological impact is only known for 43 NIS, which is less than 50% of the species registered in the sea. The highest biopollution (BPL = 3, strong impact) occurs in coastal lagoons, inlets and gulfs, and the moderate biopollution (BPL = 2) in the open sea areas (Figure 5.1). None of the Baltic sub-regions got low impact classifi cations (BPL = 0 or 1) indicating that invasive species with recognized impacts are established in all areas. The most widely distributed species, observed nearly all around the Baltic Sea were Marenzelleria spp., Potamopyrgus antipodarum, Eriocheir sinensis, Cercopagis pengoi, Mya arenaria and Balanus improvisus. However, their magnitude of impact (BPL) differed between different sub-regions of the sea (Figure 5.2). For seven species (Neogobius melanostomus, Obesogammarus crassus, Pontogammarus robustoides, Dreissena polymorpha, Gammarus tigrinus, Balanus improvisus and Cercopagis pengoi) high biopollution level (BPL = 3) was defi ned in one or more analyzed subregions. None of the analyzed species got the maximum biopollution level (BPL = 4).
Figure 5.1. Biopollution level in the assessed sub-regions in the Baltic Sea (lighter regions have BPL = 2 moderate biopollution, darker BPL = 3 strong biopollution). Numbers in parentheses indicate the number of impacting non-indigenous species in an assessment unit (with BPL>0). BPL may get values from 0 to 4. 209
