Introduction

• Over 90 percent of the world’s trade is operated through

shipping (IMO, 2012).

• Approximately 3 to 5 billion tons of ballast water is

transferred internationally by shipping each year.

• Regulation A-4 (IMO, 2009);

Environmental matching RA Species’ Biogeographical RA Species-specific RA Compares environmental conditions between locations and evaluates species distribution according to them. Assesses the

• verlap of native

and non-native species to analyze the environmental similarity and to identify the target species. Evaluates the invasive characteristics individually for the identified target species.

• Helcom & OSPAR RA tool (HELCOM & OSPAR, 2015);

Responsible traffic. Courage and co-operation.

Aims and objectives

• The aim of the present study was to evaluate the operability of the RA

tool of HELCOM & OSPAR joint harmonised procedure on granting exemptions for ships under BWM Convention regulation A-4 with the following objectives; 1. To compare the target species found from the associated ports between the routes of Sköldvik – Rotterdam – Sköldvik and Kotka – Gdynia – Kotka, 2. To assess whether the found target species would be able to adapt into the recipient port habitats using the HELCOM & OSPAR RA tool, 3. To examine whether ships travelling the associated routes could be granted for exemptions from the ballast water treatment and the performance standard according to the risk levels and the potential impacts of the species in destination port habitats, and 4. To discuss the practicality of the risk assessment tool and provide potential development suggestions in order to improve the functionality

• f the tool.

• The study was done using already collected data on NIS in

the study ports, available via HELCOM/OSPAR.

• Data from the port of Rotterdam was not available in the

RA tool and therefore it was compared manually to species from Sköldvik.

Discussion – expert judgement

• Kotka – Gdynia:
• Fish-hook water flea is able to alter

food webs by grazing on smaller zooplankton (Lehtiniemi & Gorokhova, 2008).

• Fouling on fishing equipment

(Antsulevich & Välipakka, 2000).

• G. tigrinus is equally able to damage

fishing nets and is generally more competitive than native species (high population densities, tolerant to anaerobic conditions, eutrophication and high alkalinity) (Jensen, 2010).

• Exemption not granted

• Gdynia – Kotka:
• Round gobies can be a threat to

native fish species and increase eutrophication indirectly (Bunnel et al., 2005, Kornis et al., 2012).

• May have commercial value in the

future (Sapota, 2012).

• Harris mud crab feeds on native

amphipods and damages fishing equipment (Roche and Torchin, 2007, Jormalainen et al., 2016).

• Exemption could have been

granted due to round gobies being able to restrict the distribution of

• R. harrisii. Endangering and

Eutrophication-enhancing effects of round gobies not considered very likely.

• Sköldvik – Rotterdam:
• Fish-hook water flea
• Red-gilled mud worm is not

considered having significant negative impacts on invaded areas (Orlova et al., 2006). In turn, they can improve oxygen circulation in the seabed sediments (Didziulis, 2006).

• Dark false mussel can damage

fishing equipment and is able to attach on cooling water systems

• f power plants (Laine et al.,

2006, Kennedy, 2011).

• Exemption could have been

granted to the Rotterdam oil terminal (salinity 14 – 18), but not to the other terminals within the port of Rotterdam.

• Rotterdam – Sköldvik
• 9 target species presented in results were divided into 2

categories: Species that are unlikely to distribute into the Gulf

• f Finland: Asian clam, diatom C. wailesii, Pacific oyster, Slipper

limpet and Australian tubeworm.

• Most common reasons to the unlikely transfers of these species:

Poor tolerance to low oxygen/temperature/salinity conditions or to high nutrient concentrations.

• Species that could potentially transfer to the Gulf of Finland:

Zebra mussel, Quagga mussel, Gulf wedge clam and Harris mud crab.

• Zebra and quagga mussels tend to attach into power plants’

cooling water systems (Strayer, 2010). These species, as well as the Gulf wedge clam have also impact on local food webs through zoo- and phytoplankton filtration and competitive dominance (Jones and Ricciardi, 2005, Wong et al., 2010).

• Impacts of Harris mud crab were presented earlier.
• Exemption can be granted from Rotterdam oil terminal since
• nly 2 out of 9 target species were found from there and

they were considered unlikely to inhabit Gulf of Finland.

• Exemption cannot be granted if the vessel arrives from other

terminals in the port of Rotterdam.

Conclusions

• The importance of port surveys cannot be highlighted enough,

they should be conducted more often. Additionally the accuracy of these surveys is essential.

• When assessing exemptions, species adaptation and potential

effects of climate change need to be considered (Leidenberger et al., 2015).

• Exemption applications can be evaluated with the RA tool and

expert judgement, even though the operability of the tool can be significantly improved by enhancing the frequency and accuracy of port surveys.

• Simplicity of the RA tool enables the user to concentrate on

individual species characteristics, instead of implicitly stating definite answers for the decision-making processes.

• Utilization of complex species distribution models can lead to high

uncertainties.
