1. Purpose of this guidance

1.1

The Orkney Islands Marine Region: Finfish Farming Spatial Guidance is a decision support tool that should inform decision making by public authorities and developers on finfish farm development proposals in the Orkney Islands marine region.

1.2

The purpose of this Spatial Guidance is to:

  • support the implementation of the Orkney Islands Regional Marine Plan Sector Policy 2b: Finfish and shellfish farming;
  • identify areas of greater and lesser potential sensitivity and/or constraint for finfish farming development in the Orkney Islands marine region;
  • provide greater clarity for stakeholders on the significance, and potential sensitivity of identified environmental, historic, social, economic and infrastructure features, or receptors, to finfish farming development; and
  • inform stakeholder understanding and participation in the planning and decision-making process for finfish farming development.

2. Policy context

2.1

Orkney Islands Marine Region: Finfish Farming Spatial Guidance is non-statutory planning guidance that supports the implementation of the Orkney Islands Regional Marine Plan Sector Policy 2b: Finfish and shellfish farming (see below). Sector Policy 2b vi. states that proposals for finfish farming development should have regard to this spatial guidance.

Sector Policy 2: Aquaculture

Sector Policy 2a: Safeguarding the operation of active aquaculture sites

Proposals for development and/or activities should avoid, minimise and/or appropriately mitigate significant adverse impacts on the operation of active aquaculture sites.

Sector Policy 2b: Finfish and shellfish farming

i. Proposals for finfish and shellfish farming development and/or activities should have regard to:

  • the Orkney Local Development Plan;
  • the National Marine Plan;
  • the National Planning Framework; and
  • any Marine Directorate or SEPA licensing requirements and guidance.

ii. Proposals for finfish and shellfish farming development and/or activities should avoid, minimise and/or appropriately mitigate significant adverse impacts on:

  • landscape and/or seascape character and visual amenity;
  • nature conservation designations, protected species, and the wider biodiversity, including the national status of Priority Marine Features;
  • seal haul-out sites;
  • wild salmonid fish populations due to sea lice and/or escapes (applies to finfish farming only);
  • water quality, biological carrying capacity and the benthic environment;
  • historic environment assets;
  • other coastal and marine users including, but not limited to, commercial fishing, shipping and navigation, port and harbour infrastructure/operations, active aquaculture sites, marine cable routes and pipelines, tourism, recreation, and sport and leisure activities; and
  • amenity, including consideration of road traffic, noise, light, access, vibration, odour and litter impacts.

iii. Proposals for finfish and shellfish development and/or activities should ensure appropriate measures are included to prevent the introduction and spread of non-native species.

iv. New finfish farms should not bridge Disease Management Areas, although boundaries may be revised by the Marine Directorate to take account of any changes in fish farm location, subject to the continued management of risk.

v. Appropriate planning conditions and, where necessary, a financial bond or a letter of credit will be concluded to ensure that decommissioning and site restoration arrangements will be implemented following cessation of the operation.

vi. Proposals for finfish farming development should have regard to the Orkney Islands Marine Region: Finfish Farming Spatial Guidance.

vii. Proposals for shellfish farming development should have regard to the Orkney Islands Marine Region: Shellfish Farming Spatial Guidance, where available.

3. How to use this guidance

3.1

This guidance should be used to guide decision making on finfish farming development in the Orkney Islands marine region. It does not identify locations that are suitable or unsuitable for finfish farm development. The Spatial Guidance is a decision support tool to help identify areas of greater and lesser sensitivity and/or constraint to finfish farming development.

3.2

There are environmental, historic, social, economic and infrastructure features, or receptors, in the Orkney Islands marine region and adjacent coastal areas, that can be affected by finfish farming development and/or activities. This Spatial Guidance identifies the location, significance and potential sensitivity of these receptors to finfish farm development.

3.3

The Spatial Guidance receptors have been selected in accordance with the criteria in the Orkney Islands Regional Marine Plan, Sector Policy 2b ii. Table 1 identifies the relevant receptors along with their spatial extent and the Orkney Islands Regional Marine Plan policies that are relevant to each receptor. These receptors include, for example, designated nature conservation sites and electricity cables.

3.4

Receptors have varying levels of significance. For example, internationally rare or vulnerable habitats or species have greater significance than habitats or species that are more common and/or of lesser conservation importance.

Receptors can also have higher or lower levels of sensitivity to finfish farming development and/or activities. For example, the various Priority Marine Features have different levels of sensitivity to organic enrichment associated with finfish farming development and/or activities. Where relevant, a receptor’s significance value is assigned on the basis of its position within the hierarchy of international, national and regional/local importance.

3.5

Table 2 provides information on the significance, and potential sensitivity of the identified environmental, historic, social, economic and infrastructure receptors to finfish farm development. The receptors have been assigned values according to their significance and their potential sensitivity, as identified in Table 2. The location, and significance and sensitivity values, of the receptors are identified in the guidance maps in Section 7: Spatial Guidance.

3.6

Further information on the identified nature conservation receptors, and their potential sensitivity to finfish farm development and/or activities, is provided in Appendices 1 to 4.

3.7

The significance of any potential impact or effect associated with a specific finfish farming development or activity proposal is influenced by factors including, but not limited to, location, scale, siting and design, and any appropriate development specific mitigation measures. These development specific impacts or effects, and associated mitigation measures, are assessed as part of the relevant statutory consenting processes. For the purposes of this guidance, the assessments have been undertaken prior to the consideration of any development or site-specific mitigation.

4. Online interactive maps

4.1

A web-based interactive spatial tool can be accessed at Orkney Islands Marine Region: Finfish Farming Spatial Guidance. This service allows users to identify nearby receptors from a given point by clicking on a desired location. The search distance from the clicked location can be set by the user, for example, all receptors within 1 km, with the option to view further information on the receptors present within the search area.

5. Receptor updates

5.1

It is important that the location, significance and sensitivity of the receptors is identified using the most up to date data. The receptor locations identified in Appendix 5, Table A6, may be periodically reviewed and updated using the identified data sources. Relevant receptors may also be periodically updated to reflect updates to the Feature Activity Sensitivity Tool (FeAST). These updates may be made to this Spatial Guidance without the need for further public consultation on an updated spatial guidance document.

6. Identified Receptors

Table 2 provides information on the significance, and potential sensitivity of the identified environmental, historic, social, economic and infrastructure receptors to finfish farm development and/or activities.

Table 2: Significance and sensitivity of receptors

Significance and sensitivity values are assessed on a scale of 1 to 3, where 1 is low, 2 is medium and 3 is high.

ReceptorSignificance valueReceptor significanceSensitivity valueReceptor sensitivity to finfish farming development and/or activities
Special Protection Areas (SPA)3Special Protection Areas (SPAs) are selected to protect one or more rare, threatened or vulnerable bird species listed in Annex I of the Birds Directive, or certain regularly occurring migratory species. SPAs are of international conservation significance.2–3An individual site sensitivity value has been assigned to relevant SPAs within Orkney and the Orkney Islands marine region. The sensitivity value for each SPA has been assigned on the basis of the sensitivity of the site’s qualifying bird features to pressures from finfish farming development and/or activities. Refer to Appendix 1. The Orkney SPAs with qualifying features that have no identified pressure/interaction with finfish farming development and/or activities have been screened out and are therefore not included in the significance and sensitivity maps in this Spatial Guidance. SPAs outwith Orkney and the Orkney Islands marine region have potential connectivity with proposed finfish farming development and/or activities in Orkney. These SPAs are not identified in this Spatial Guidance.
Special Areas of Conservation (SAC)3SACs are of international conservation significance. SACs in Scotland are designated by Scottish Ministers under the European Union (EU) Habitats Directive. They are areas which have been identified as best representing the range and variety within the EU of habitats and (non-bird) species listed on Annex I and II to the Directive. SACs in terrestrial areas and marine areas out to 12 nautical miles are afforded protection through the Conservation (Natural Habitats, &c.) Regulations 1994, as amended.3An individual site sensitivity value has been assigned to relevant SACs within Orkney and the Orkney Islands marine region. The sensitivity value for each SAC has been assigned on the basis of the sensitivity of the site’s qualifying features to pressures from finfish farming development and/or activities. Refer to Appendix 2.
Nature Conservation Marine Protected Areas (NC MPA)2Nature Conservation Marine Protected Areas (NC MPAs) protect a wide range of habitats, species, geology and undersea landforms in Scottish waters. NC MPAs are statutory designations under the Marine (Scotland) Act 2010 and are of national significance.3An individual site sensitivity value has been assigned to each NC MPA within the Orkney Islands marine region. The sensitivity value for each NC MPA has been assigned on the basis of the sensitivity of the site’s protected features to pressures from finfish farming development and/or activities. Refer to Appendix 3.
PMF: Maerl beds, seagrass beds, flame shell beds, horse mussel beds and fan shell aggregations2–3PMFs are species and habitats which have been identified as being of conservation importance in Scotland. PMFs are a subset of species and habitats identified on national, UK or international lists. Therefore, all PMFs are of at least national conservation significance in Scotland, but may be of UK level or international significance. Each PMF recorded in the Orkney Islands marine region has been attributed a significance value on the basis of national or international conservation status. Refer to Appendix 4.3The sensitivity of PMFs to pressures from finfish farming development and/or activities has been assigned using the Feature Activity Sensitivity Tool (FeAST) and advice provided by NatureScot.

Appendix 1: Special Protection Areas and qualifying features sensitivity assessment

A1.1

Special Protection Areas (SPAs) that have no identified pressure/interaction to their qualifying features with finfish farming development and/or activities have been screened out and are therefore not included in Map 3 (Nature Conservation Significance and Sensitivity).

A1.2

An individual site sensitivity value has been attributed to the relevant SPAs within Orkney and the Orkney Islands marine region that have a pathway to impact from finfish farming development and/or activities.

A1.3

The sensitivity value for each SPA has been attributed on the basis of the sensitivity of the site’s qualifying bird features to finfish farming development and/or activities.

A1.4

The assessment of relevant finfish farm consent applications will take into account, through the relevant process, any impacts or effects on receptors located outwith the Orkney Islands marine region.

A1.5

The foraging ranges of the SPA qualifying features are identified in Table A2.

A1.6

The sensitivity value for each SPA has been attributed by following steps 1 to 4:

  1. Identify the qualifying features for each SPA (see Table A1: Column B).
  2. Identify the pressures/interactions from finfish farming development and/or activities for each SPA qualifying bird feature using FeAST assessments (see Table A2: Column B).
  3. Identify the sensitivity of the qualifying bird features to each pressure/interaction using values of low (1), medium (2) or high (3). For qualifying bird features affected by multiple pressures/interactions, the highest pressure sensitivity value was assigned to the feature (see Table A2: Column C).
  4. The individual SPA sensitivity value was assigned based on the most sensitive qualifying feature within the SPA citation (see Table A1: Column E).

Appendix 2: Special Areas of Conservation assessment

A2.1

SACs that have no identified pressure/interaction to their qualifying features with finfish farming development and/or activities have been screened out and are therefore not included in Map 3 (Nature Conservation Significance and Sensitivity).

A2.2

An individual site sensitivity value has been attributed to the SACs within Orkney and the Orkney Islands marine region that have a pressure/interaction to their qualifying features from finfish farming development and/or activities.

A2.3

The sensitivity value for each SAC has been attributed on the basis of the sensitivity of the site’s qualifying features to finfish farming development and/or activities.

A2.4

The assessment of the relevant finfish farm consent applications will take into account, through the relevant process, any impacts or effects on receptors located outwith the Orkney Islands marine region.

A2.5

The sensitivity value for each SAC has been attributed by following steps 1 to 4:

  1. Identify the qualifying features for each SAC (see Table A3: Column B).
  2. Identify the pressures from finfish farming development and/or activities on each SAC qualifying feature in consultation with NatureScot (see Table A3: Column C).
  3. Identify the sensitivity of these qualifying features to each identified pressure using values of low (1), medium (2) or high (3) (see Table A3: Column D).
  4. Assign the individual SAC sensitivity value based on the most sensitive qualifying feature within the SAC citation (see Table A3: Column E).

Appendix 3: Nature Conservation Marine Protected Areas assessment

A3.1

An individual site sensitivity value has been attributed to the Nature Conservation Marine Protected Areas (NC MPA) within the Orkney Islands marine region that have protected features with identified pressure/interaction with finfish farming development and/or activities.

A3.2

The sensitivity value for each NC MPA has been attributed on the basis of the sensitivity of the site’s protected feature(s) to finfish farming development and/or activities.

A3.3

The assessment of the relevant finfish farm consent applications will take into account, through the relevant process, any impacts or effects on receptors located outwith the Orkney Islands marine region.

A3.4

The sensitivity value for each NC MPA has been attributed by following steps 1 to 4:

  1. Identify the protected features for each NC MPA (see Table A4: Column B).
  2. Identify the pressures from finfish farming development and/or activities on each NC MPA protected feature using Feature Activity Sensitivity Tool (FeAST) assessments (see Table A4: Column C).
  3. Identify the sensitivity of these qualifying features to each pressure using values of low (1), medium (2) or high (3) (see Table A4: Column D).
  4. Assign the individual NC MPA sensitivity value based on the most sensitive qualifying feature within the NC MPA designation (see Table A4: Column E).

Appendix 4: Priority Marine Features assessment

A4.1

The Geodatabase of Marine Features Adjacent to Scotland (GeMS) PMF records within the Orkney Islands marine region are identified in Map 2. There are PMF locations that have not yet been recorded and are therefore not identified in the spatial data used within this Guidance. PMF records will be periodically updated within this Guidance as detailed in Appendix 5 to incorporate any updated records.

A4.3

PMFs are a subset of species and habitats identified on national, UK or international lists. Therefore, all PMFs are of at least national conservation significance in Scotland, but may be of UK level or international significance. Each PMF recorded in the Orkney Islands marine region has been attributed a significance value on the basis of national or international conservation status. Refer to Table A5 for the conservation status and significance value attributed to relevant PMF.

A4.4

An individual PMF sensitivity value has been attributed to PMFs within the Orkney Islands marine region that have identified pressure/interaction with finfish farming development and/or activities.

A4.5

The sensitivity value for each PMF has been attributed by following steps 1 to 5:

  1. Identify the PMFs present within Orkney’s marine region (Table A5, Column A).
  2. Advice was taken from NatureScot on which PMFs to include within the Spatial Guidance.
  3. Identify the pressures/interactions on the selected PMFs from finfish farming using Feature Activity Sensitivity Tool (FeAST) assessments (see Table A5: Column D).
  4. Identify the sensitivity of selected PMFs to each pressure using values of low (1), medium (2) or high (3) (Table A5, Column E).
  5. Assign the overall PMF sensitivity value based on the highest sensitivity of a FeAST-listed pressure/interaction (Table A5, Column F).
