Background

Many of the science issues facing DFO (Fisheries and Oceans Canada)are associated

with significant knowledge gaps and uncertainties. This,however,does not relieve the

department of the need to make decisions onthese issues. Under these conditions,

Fisheries and Oceans Canada (/index-eng.htm)

CEARA - DFO Science Page 1 of 13

http://www.dfo-mpo.gc.ca/science/coe-cde/ceara/index-eng.htm 6/22/2016
decisions must balance the risks and uncertainties while ensuring the sustainability of

Canada's aquatic ecosystems. Risk assessment is the process of estimating the risk

presented by a hazard,ineither qualitative or quantitative terms,to aquatic ecosystems,

fisheries resources,fish habitat,and aquaculture that DFO (Fisheries and Oceans

Canada)is mandated to manage and protect. DFO (Fisheries and Oceans Canada)

currently faces hazards from aquatic invasive species (AIS),climate change,and fish

habitat alteration,with the potential for any or all of these hazards to impact species at risk

(SAR),biodiversity,aquaculture,or fisheries resources. AIS (Aquatic Invasive Species )

are now considered one of the lead threats to native biodiversity (Sala et al. 2000,

Dextrase and Mandrak 2006)imposing significant economic costs with just 18invasive

species (aquatic and terrestrial)estimated to cost Canada $13.3-34.5 billionper year

(Colautti et al. 2006). Sea lamprey,as anexample of successful control,currently costs

the Great Lakes Fishery Commission(GLFC)$20 million(US)per year to limit the impact

of sea lamprey inthe Great Lakes with the GLFC incurring costs to control sea lamprey

every year for the past 30 years.

The National Code onIntroductions and Transfers of Aquatic Organisms identifies risk

assessment as central to the process of assessing proposals to move aquatic organisms.

The CanadianActionPlanto Address the Threat of Aquatic Invasive Species identifies risk

assessment as one of the implementationstrategies to deal with the threat of AIS (Aquatic

Invasive Species ). However,DFO (Fisheries and Oceans Canada)lacks the widespread

expertise to develop the risk assessment tools and methods needed to provide science

advice with a consistent national approach. By forming the Centre of Expertise for Aquatic

Risk Assessment (CEARA),DFO (Fisheries and Oceans Canada)cantake the first steps

toward developing the necessary expertise inrisk assessment across the country,building

onexpertise developed inBurlingtonat the Great Lakes Laboratory for Fisheries and

Aquatic Sciences,and providing a concentrationof experts necessary to stimulate the

spread of expertise to other regions. CEARA (Centre of Expertise for Aquatic Risk

Assessment)will be led from the Central and Arctic Regionbut will draw members from all

regions of the country and build uponexisting working relations with Canadianand

Americanexperts inrisk assessment.

Canada formally committed to control,eradicate or prevent the introductionof invasive

species that threatenecosystems,habitat or species under the 1992 Conventionon

Biological Diversity,with DFO (Fisheries and Oceans Canada)responsible for AIS

(Aquatic Invasive Species ). CEARA (Centre of Expertise for Aquatic Risk Assessment)

will assist DFO (Fisheries and Oceans Canada)to fulfil this responsibility by developing

scientifically defensible risk assessment methods and tools that canthenbe applied to the

CEARA - DFO Science Page 2 of 13

http://www.dfo-mpo.gc.ca/science/coe-cde/ceara/index-eng.htm 6/22/2016
issue of invasive species to identify key points inthe invasionpathway and maximize the

efficient use of limited resources to achieve the greatest potential for the prevention,

eradicationor control of AIS (Aquatic Invasive Species ).

Mandate and Objectives

The mandate of CEARA (Centre of Expertise for Aquatic Risk Assessment)is to develop

national standards for,and to provide guidance on,scientifically defensible biological risk

assessment. This mandate will be achieved by developing guidance documents,and

holding national workshops to educate practitioners onthe risk assessment process.

CEARA (Centre of Expertise for Aquatic Risk Assessment)will also be responsible for

identifying risk assessment priorities and tracking national risk assessments to provide

science advice related to healthy and productive aquatic ecosystems and sustainable

fisheries and aquaculture.

The objectives and deliverables for CEARA (Centre of Expertise for Aquatic Risk

Assessment)are: 1)to develop a national standard for conducting biological risk

assessments of AIS (Aquatic Invasive Species ),to be peer-reviewed at a CSAS

(CanadianScience Advisory Secretariat)workshop (held inJune 2006 and againinJune

2008);2)to convene a national workshop to educate practitioners onthe risk assessment

process (held inJune 2006);3)to develop a process for prioritizing risk assessment needs

(draft completed FY 2009/10);and,4)to coordinate the tracking of national risk

assessments (ongoing). Risk assessments will be undertaken,ona priority basis,by

experts across Canada.

Management and Reporting Structure

CEARA (Centre of Expertise for Aquatic Risk Assessment)will consist of a Directorate,a

National Executive Committee and anExpert Network.

CEARA (Centre of Expertise for Aquatic Risk Assessment)

Directorate

CEARA (Centre of Expertise for Aquatic Risk Assessment)will be led by a Directorate

comprised of anExecutive Director and a Manager,residing at the Great Lakes Laboratory

for Fisheries and Aquatic Sciences (GLLFAS)inBurlington,Ontario. Dr. Nicholas Mandrak

is the Executive Director of the CEARA (Centre of Expertise for Aquatic Risk Assessment),

and will chair the National Executive Committee. The Manager will report to the Executive

Director,and will provide support for the work of the National Executive Committee. The

CEARA - DFO Science Page 3 of 13

http://www.dfo-mpo.gc.ca/science/coe-cde/ceara/index-eng.htm 6/22/2016
Directorate will be responsible for developing guidance documents,holding national

educational workshops,coordinating the tracking of national risk assessments,providing

advice to headquarters onnational risk assessment priorities,allocating funds to regions

as required,and ensuring that deliverables are met.

The Executive Director of CEARA (Centre of Expertise for Aquatic Risk Assessment)will

have dual reporting responsibilities. Supervisory reporting will be to Regional Director of

Science Central and Arctic Region. Functional reporting onthe activities and deliverables

of CEARA (Centre of Expertise for Aquatic Risk Assessment)will be to the Director of

Environment and Biodiversity Science who will inturnreport to the Director General of

Ecosystem Sciences. The Regional Director of Science,Central and Arctic Regionwill be

responsible for reporting to NSDC (National Science Directors Committee).

National Executive Committee

The National Executive Committee of CEARA (Centre of Expertise for Aquatic Risk

Assessment)will be comprised of the CEARA (Centre of Expertise for Aquatic Risk

Assessment)Directorate and a science representative from each of the other regions,

including headquarters. The National Executive Committee will be responsible for ensuring

that CEARA (Centre of Expertise for Aquatic Risk Assessment)fulfills its primary

objectives withinthe scheduled time frame. It will also be responsible for identifying risk

assessments priorities onanannual basis,and developing anannual work planto be

submitted to the NSDC (National Science Directors Committee)by the RDS.

Expert Network

The Expert Network will be comprised of scientists with risk assessment and aquatic

invasive species expertise,from withinand outside the department (e.g. researchers

involved inthe NSERC (National Science and Engineering Research Council of Canada)

AIS (Aquatic Invasive Species )Network),who canassist inaddressing issues important

to DFO (Fisheries and Oceans Canada). The Expert Network will allow for a broader

representationfrom withinDFO (Fisheries and Oceans Canada),as well as a national

representationfrom other federal departments,whenappropriate (e.g. Transport Canada).

Scientists involved inthe NSERC (National Science and Engineering Research Council of

Canada)AIS (Aquatic Invasive Species )Network should be part of the CEARA (Centre of

Expertise for Aquatic Risk Assessment)Expert Network. The mainroles of the Expert

Network are to peer-review guidance and risk assessment documents,and to provide

advice to the National Executive Committee as requested.

Liaison, Communication and Outreach

The National Executive Committee will hold regular meetings via conference call,and one

annual meeting/workshop. Communications and travel costs will be paid out of the

operating funds provided to CEARA (Centre of Expertise for Aquatic Risk Assessment).

The Expert Network will not meet regularly,but will be invited to participate by internet,

conference calls or workshops,as warranted,whenthe National Executive Committee

requires peer review and expert advice.

Objectives,activities and deliverables of CEARA (Centre of Expertise for Aquatic Risk

Assessment)will be communicated through anannual work planprovided inFebruary of

the preceding year and anannual report provided by June of the following year.

The development of national risk assessment standards will be peer-reviewed following

the National Advisory Process (NAP)and communicated inCanadianScience Advisory

Secretariat (CSAS)Science Advisory documents. The proceedings of workshops held to

educate practitioners regarding risk assessment will be published as CSAS (Canadian

Science Advisory Secretariat)Proceedings documents. All documents related to risk

assessments (e.g. synopses,assessments,proceedings)will be published as CSAS

(CanadianScience Advisory Secretariat)documents. The publicationof all CSAS

(CanadianScience Advisory Secretariat)documents will be done within3 months after the

completionof NAP (National Advisory Process)workshops inaccordance to CSAS

(CanadianScience Advisory Secretariat)guidelines. All risk assessments,and related

documents,will be tracked by the National Executive Committee,and made available

through a dedicated page onthe CSAS (CanadianScience Advisory Secretariat)website.

To further communicate risk assessment procedures and applications,and to broadenthe

scope of review,authors of CSAS (CanadianScience Advisory Secretariat)documents

may also publish results inprimary journals,if warranted.

The risk of invasionof aquatic ecosystems by AIS (Aquatic Invasive Species )is anissue

of interest to all Canadians,and a wide variety of outreach programs are currently being

planned by DFO (Fisheries and Oceans Canada)and its partners. Outreach to the general

public,specifically related to risk assessment of AIS (Aquatic Invasive Species ),will be

achieved through a risk assessment tracking page onthe CSAS (CanadianScience

Advisory Secretariat)website that will provide coordinated access to all risk assessment

documents (e.g. synopses,assessments,proceedings)ona project by project basis.
