Why Offshore Shellfish Culture:Environment;

Increased water flow leading to higher

phytoplankton levels & dispersal of detritus

Generally superior water quality - Classifications

Less impacts of diffuse pollution e.g. faecal run-off from agricul.

Lower shellfish disease/pathogen load e.g. oysters

Food Safety;

Less norovirus / microbial contaminants / HABs

Economics & Operational;

Inshore = Lack of sites / Competition for space / Visual impact

Greater economies of scale with large farms

EU & Govt. Stance; Importance now recognised

ASP

This is the question that is asked by this sector…

Raises revenue for The Crown Estate

Efficient use of the marine space

Food security

Less large traffic through wind farm sites

Known environmental and bathymetric parameters

Potential exclusion of other activities

Agreements and procedures:Mussel cultivation trial proposal / Method statement

Code of Practice / Operational plan

Marine emergency response plan / Risk assessment

Vessel Insurance

Permission from CCW / Permission from Welsh Government

Funding:Welsh European Fisheries Fund (EFF) & WG

50:50 ratio of Funding to Time CIK from Project Partners

45 days dedicated to deliverable production

Project Partners: Includes renewable energy companies, renewablesupport organisations, conservation agencies, Welsh Government,aquaculture industry + support & trade organisations, NGOs, researchorganisations, landowners, UK Government organisations

Duration:9-10 Month Project

Start date: 01 Oct. 2012 / End date: June-July 2013

Deliverables: Two main reports -

Reports guided by Project Meetings, one-to-one interviews, smallworkshops, planning case-study…

Page 10: SAGB2013 Martin Syvret (Aquaculture Solutions Ltd.)

Advisory Group & Stakeholder input on:

1. What the review should cover?

2. Known past studies & trials

3. Identify suitable forms of shellfish aquaculture

4. Permission & tenure

5. Requirements for a safe & compatible approach to shellfishculture in wind farms

6. Nature conservation interests

7. Key policy drivers from all sectors

End point = guidance / recommendations on what shellfish culturetypes most suitable now or in near future – not MUPS!

Page 11: SAGB2013 Martin Syvret (Aquaculture Solutions Ltd.)

Offshore Locations; Site choice dependent on temp. regime, water quality, plankton resource, seed availability, substrate type, depth, current velocity, other uses etc.

Farm size likely to be in 10km2+ sites?

Offshore Technology; New & innovative equipment designed to operate under extreme environmental conditions

Larger spaces allows low density & therefore low impact farm operations with lower unit production costs

Increased potential for mechanisation

Scale of Production; High capital outlay for these systems means that high output levels required if farms to be economically viable

Buck et. al., 2010

Page 13: SAGB2013 Martin Syvret (Aquaculture Solutions Ltd.)

Advisory Group & Stakeholder input on:

1. Infrastructure for shellfish cultivation & installation

2. Husbandry types including deposition and harvesting methods

3. Safe access & development of a Safe Access Protocol

4. Operational compatibility of shellfish cultivn. & wind farm operation

5. Shellfish cultivation & nature conservation interests

6. Emergency procedures

End point =

A practical Manual on how to safely cultivate shellfish in Welshoffshore wind farm sites

Takes into account requirements of wind farm operators & natureconservation designations

WFO risk perception with ‘Christmas tree’

Page 17: SAGB2013 Martin Syvret (Aquaculture Solutions Ltd.)

Key:

Fixed gear aquaculture

Seabed culture (e.g. seed mussel)

Scour protection (AR ranching – e.g. lobster)

Fishing – dredging zone

Conservation – monitoring zone

Page 18: SAGB2013 Martin Syvret (Aquaculture Solutions Ltd.)

Marine parks and nature conservation spatial pressures are drivers for co-location or multi-functional use

Marine Spatial Planning is advanced and has shown how limited the space resource now is in German waters

Many Wind Farms 60km+ offshore and so face challenges with depth

Page 19: SAGB2013 Martin Syvret (Aquaculture Solutions Ltd.)

Dredging not allowed within offshore sites & so targeting fixed gear aquaculture e.g. rope-mussels, cage culture of oysters

Mussel spat availability is constant when settling on ropes

Connecting equipment to and away from wind turbines has been considered

Construction: Was due 2011, now planned for 2015, permit may be sold…

Page 21: SAGB2013 Martin Syvret (Aquaculture Solutions Ltd.)

Limitations;No risk assessments carried out of WFO vs. aquaculture e.g. drifting rope-mussel lines

Experience so far is only with working at Pilot-scale studies i.e. extrapolation to commercial-scale is still theoretical

Environmental impacts, nutrient flux research etc. is through tank-based research only

Research Need;Commercial-scale research trial required to provide real data:

To test theoretical assumptions of environmental & ecological research

To ground-truth models and economic predictions

To investigate operational practises and test equipment and techniques

To investigate the potential for Co-Management

International co-operation & funding to meet this need?

Page 22: SAGB2013 Martin Syvret (Aquaculture Solutions Ltd.)

Policy Drivers - German experience;Lots of discussions about benefits of co-location but for years there has been no progress on implementing practical projects

Recently changed due to the introduction of a law/regulation

WFDs must investigate prospects for co-location when submitting an application for a permit to develop a wind farm

No investigation (even if result is negative) = no permit

Demonstrates the need for Top Down intervention!

Page 23: SAGB2013 Martin Syvret (Aquaculture Solutions Ltd.)

Why should the WFDs/WFOs get involved; What is in it for them?

“The challenge to developing offshore co-location is not technical but revolves around the ability to persuade

WFDs/WFOs to work with the aquaculture sector”

(Prof. Bela Buck, AWI Institute)

How to persuade the WFOs to co-locate;Socio-economic study: ‘Community Benefit Fund’ applicability informed by study

Scoping overview for this socio-economic study is planned and seeking funding

WFDs to become the developer of choice!

Successful Co-location of WFs &

Aquaculture

TOP DOWN APPROACH Policy drivers – Requiring and/or Incentives – Encouraging

Role for Defra / WG / MMO / TCE

BOTTOM UP APPROACHRequires - Industry Interest / Investment / Know-how

Investment – Supported by Funding

Commercial-scale Trials to test;

• Theories/Models• Environ. impacts

• Operational aspects• Technical challenges• Ecosystem services

• Economics

Socio-Economic Study to;

Highlight & Quantifypotential wider benefits of co-location
