Inthepast,traditionalfisherytechniqueswereusedtodetecttheleadingedgeoftheAsiancarp population;however,thismethodwassomewhatineffectiveattargetingthesespeciesatlowdensities. TheUniversityofNotreDame,withfundingfromtheUSACE,developedamethodthatdetected “environmental”DNA(eDNA)leftbehindintheaquaticsystembythetargetedspecies.Environmental DNAentersthesystemthroughavarietyofmechanisms,someofwhichincludesloughingofexternal epidermalcellsintothewater,sloughingofinternalepidermalcellsintofecesandintothewater,andas tissueresiduesfollowinginjuryorpredation.ThedetectionofeDNAinwatersamplesisbasedonwhole DNAextractionfromparticulateorganicandinorganicmatterfoundinthewaterandpolymerasechain reaction(PCR)assaysforspecies‐specificmitochondrialDNAmarkers. UseofthismethodistoprovidedetectionofAsiancarpatlowdensitiesandtoserveasanearlydetection systemofthespreadofAsiancarpintopreviouslyuninhabitedareas.TheoriginalQualityAssurance ProjectPlan(QAPP)detailingtheeDNAmonitoringprocess,includingmethodologiesandquality controls,wasrequestedfromtheU.S.ArmyEngineerResearchandDevelopmentCenter(ERDC)asthe USACEassumedeDNAmonitoringresponsibilityfromtheUniversityofNotreDame.ThismodifiedQAPP willbefollowedbytheU.S.FishandWildlifeService(USFWS)officesresponsibleforfieldsamplingand labprocessingofeDNAsamples.FishandWildlifeConservationoffices(FWCO)willhandlefield samplingandtheWhitneyGeneticsLab(WGL)attheLaCrosseFishHealthCenterwillprocesseDNA samplessincetheUSFWSassumedresponsibilityformonitoringAsiancarpintheChicagoArea WaterwaySystem(CAWS)andotherwaterbodiesin2013.

ThesedocumentsservedasthebasisfortheQAPPfollowedbyERDC.Additionally,USACEsubmittedthe eDNAmethodologyforanIndependentExternalPeerReview(IEPR),whichisarequirementtoexamine decisiondocumentsandsupportingworkproductswheretherearepublicsafetyconcerns,significant controversy,ahighlevelofcomplexity,orsignificanteconomic,environmentalandsocialeffectstothe nation.Releasedfallof2011,theeDNAIEPRreport,conductedbyobjectivepanelistswithtechnical expertiseingeneticsandpopulationecology,confirmedeDNAsamplingandtestingmethodologyis soundfordetectingSilverandBigheadcarpDNAbutcannotindicatethesourceofAsiancarpDNA (informationonthesize,gender,ageandnumberofindividualspresentandcannotdistinguishbetween pureSilverorBigheadcarpandtheirhybrids).In2013,theWGLreceivedtheQAPPandmadechanges sothatitwouldbeapplicabletothenewfieldsampleprocessingandeDNAprocessingpersonneland theirspecificlocations.ItwasalsomodifiedaccordingtoresultsoftheeDNACalibrationStudies(ECALS) andlabvalidationscarriedoutbytheinteragencyECALSteam.Annualmodifications(seesection1.8)to theQAPPwillbeapprovedbyregionalfieldstaff,theUSFWSeDNAteam,andleadershipofUSFWS MidwestRegion.Changestosampleanalysiswillundergopeer‐reviewbyexternalexpertsandvalidation inspecificallydesignedstudiescarriedoutinatleastthreedifferentlaboratories. 1.4 Objective TheobjectiveofthisQAPPistoprovidedetailedproceduresforAsiancarpeDNAsamplecollection, sampleprocessing(includingfiltering,centrifuging,DNAextraction,PCR,biomarkeranalysis,DNA sequencing),datareporting,andqualitycontrol/qualityassuranceprocedurestoensurethatdataareas technicallydefensible,consistent,andusableaspossible.Thespecificgoalsandobjectivesofsampling plansforparticularbodiesofwaterarecurrentlydirectedbytheappropriategoverningbody.For example,theChicagoAreaWaterwaysamplingplanhasbeenissuedbytheAsianCarpRegional 1‐2 CoordinatingCommittee’sMonitoringandResponseWorkgroupintheMonitoringandResponsePlan.

B‐7 AppendixC: FOR IMMEDIATE RELEASE Month XX, XXXX Contact(s): Name of Agency, Contact Name, Phone Number Name of Partner Agency, Contact Name, Phone Number MAIN TITLE Subtitle Analysis of water samples taken from [insert water body] on [insert date] have tested positive for the presence of Asian carp environmental DNA, also known as eDNA. Out of [insert total number of water samples] water samples collected by the [insert agency], [insert number] have traces of genetic material from [insert Asian carp species, e.g. bighead and/or silver]. The eDNA samples were collected as part of an extensive monitoring effort in [insert all water bodies sampled]. The samples were processed by the U.S. Fish and Wildlife Service’s Whitney Genetics Lab in La Crosse, Wisconsin. [Insert agency VIP quote explaining what the positive eDNA findings mean] In response to the positive findings [insert next steps]. eDNA can be left in the environment in the form of scales, cells, feces or mucus. At present, eDNA evidence cannot verify whether live Asian carp are present, whether the DNA may have come from a dead fish, or whether water containing Asian carp DNA may have been transported from other sources such as bilge water, storm sewers or fisheating birds. The U.S. Fish and Wildlife Service, U.S. Army Corps of Engineers and the U.S. Geological Survey are leading a multi year Asian Carp Environmental DNA Calibration Study (ECALS), funded through the Great Lakes Restoration Initiative, to improve the understanding and interpretation of Asian carp eDNA results. For more information on ECALS, please visit www.asiancarp.us/ecals. eDNA results from this sampling event can be viewed at: www.fws.gov/midwest/fisheries/eDNA.html For more information on the science of eDNA in the fight against Asian carp, watch the video at: http://youtu.be/xXwply6ahQ8 .

TheobjectiveofthisstudywastodeterminewhethertheIBIkitisasgoodasorbetterthantheQiagenkit bycomparingcopiesoftargetDNAfoundinthreedifferenttypesofsamples.Inordertoavoid unnecessarycontaminationoftheeDNAlabwithAsiancarpDNA,bluegillDNAwasassayedwithreal‐ timequantitativemarkers(qPCR)(Takaharaetal.2003)afterextraction.

Thesecondpreliminarystudywasexecutedinfallof2013,when120pairedsamples(N=240)were collectedinfoursites(60samplespersite)intheChicagoAreaWaterwaySystem(CAWS).Filtered samples(N=120)werecollectedaspartoftheformalearlydetectionandmonitoringprogram(MWRG Plan2013,http://www.asiancarp.us/documents/MRP2014.pdf),butanadditionalfive50‐mlsamples (centrifuged)werecollectedside‐by‐side(N=120)witheach2‐Lsample(filtered).Thesewere extractedwiththeQiagenDNeasykitaccordingtotheQAPP.SinceeDNAofAsiancarpisnotconsistently detectedintheCAWS,markersfordetectingeDNAofbluegill(Takaharaetal.2003)andcommoncarp (Barnesetal.2014)wereusedtocomparedetectionofDNAbetweenthetwoprocessingmethodswithin eachsite.ItshouldbenotedthatTakahara’sbluegillmarkerwillalsodetectotherLepomisspecies,butit shoulddosoequallyinbothsampletypes.Resultsfromthissecondpreliminarystudybasedonfield samplesindicatedthattheprocessesdonotdiffer(PairedChi‐squaretestbysamplesite,p=0.435bluegill andp=0.947commoncarp)(Figure1).

Methods Pairedwatersampleswerecollectedandprocessedbycentrifugingandfilteringfromthreereacheswith low,medium,andhighcarpdensities(Figure2,Table3).Eachreachwassampledina2.5‐kmlong sectionencompassingtheareaofinterest.Watersampleswithineachselectedsectionweretakenat23 sitesfollowingaprobabilisticsamplingdesigntargetingareaswhereeDNAhadthehighestprobabilityof accumulation(QAPP).Attheselectedsite,surfacewater(<4cm)wascollectedinasterilizedcontainer approximately10Linvolume.Thesurfacewaterwashomogenizedanddistributedintothree2‐Lbottles andfifteen50‐mltubesdesignatedforthatsite.Each2‐Lbottleandsetoffive50‐mltubesisareplicate (n=3)forthatsite.Anew10‐LcontainerwasusedforeacheDNAaccumulationsiteandnotreused duringthisstudy.Twoofthe23samplingsiteswererandomlyselectedforcoolerblanksfilledwithDI water(i.e.,three2‐Lbottlesandfifteen50‐mlcentrifugetubespersite).Thenegativecontrolsdidnot replacethecollectionofwatersamplesatthesite,butservedasnegativecontrols.Allsampleswere filteredorcentrifugedaccordingtotheQAPPinmobileeDNAtrailersandsenttothelaboratories.One setwasshippeddirectlytoERDC,andtheothertwowerehand‐deliveredtoWGLpersonnelwhothen distributedthefinalsettoUMESCforanalysis.ThreestudyreachesintheIllinoisRiver(Figure2)were identifiedbasedonAsiancarpdensities(Table3):BrandonRoadPool(low),MarseillesPool(medium), andLaGrangePool(high;Figure2;seealsoBaerwaldtetal.2014).Sampleswerecollectedwithina2.5 kmstretchimmediatelybelowtheupstreambarrier(lockanddamstructure)withineachreach(Figure 3). AllpreparationactivitiesfollowedthosespecifiedintheQAPPandotherguidingdocuments/protocols (e.g.,eDNATrailerSOP).Watersampleswithineachrandomlyselectedsectionweretakenat23sites followingaprobabilisticsamplingapproachdescribedabove.Targetedareasincludedbackwaters,island sidechannels,pooledareas,belowandaroundstructures,confluencesoftributaries,andanyareas wherefloatingdebrisaccumulates.ActualsamplecollectionlocationsweredeterminedbytheCollection CrewLeaderfrominsituobservationsofwinddirection,accumulationareas,andwaterlevels.NoeDNA samplingoccurredwithin5daysafterasignificantrainfallevent(morethan1.5inchesina24‐hrperiod) orontherisinglimbofahydrographoftheriverasitexceededfloodstage. SampleswerecollectedaccordingtotheQAPP,andatotalof2252‐Lsamplesand112550‐mlsamples werecollected.AllsampleswereprocessedaccordingtotheQAPP,includingcentrifugesamples(QAPP alreadycontainsmethodforcentrifugationwhichisallowedforresearchpurposes),andDNAwas extractedusingtheQiagenDNeasykits.Atthetimethisstudywasplanned,theQAPPusedconventional PCRmarkersfromJerdeetal.(2011);however,aftersampleshadbeencollectedinSpringof2014but beforetheywereanalyzed(JuneatERDCandwinteratUMESCandWGL),newqPCRmarkershadbeen validatedandthusadaptedintheQAPP(Farringtonetal.2015),andthesenewmarkerswereusedto analyzesamples.Thevalidationstudyprovidedlimitsofdetection(3‐9copies)andlimitsof K‐4 quantification(10copies)forthesenewmarkers,thereforeasampleisdetectedaspositiveforamarker ifstartingcopiesoftemplateDNAarebetween3‐9,andasamplecanbedetectedaspositive,andstarting copiesoftemplateDNAcanbereportedasanumericalvaluefor10copiesorgreater. Datafromeachlabwasreportedintwoways:samplesconfirmedpositiveforBighead,Silver,orboth species,andcopynumber.Theoverallprobabilityofdetectionforpositivesampleswascalculatedfor eachreachbyeachprocessingmethodtoassessdetectionrate.Thedetectionrateforbothfiltrationand centrifugationwasthenusedtocalculatethenumberofsamplesneededtoachieveaspecifieddetection probabilityusingequationsmodifiedforbinomialvariables(McArdle1990,Reed1996,andKery2002).

Overall,resultsbetweenERDCandWGLhadsimilarratesofdetectionforbothspeciesinallthree reaches(Table4).Meancopynumbers(8replicatereactionsx25samples)variedbetweenlabs,but weresimilaramongreachesforeachprocessingmethod.MeancopynumbersalsoreflectedtheAsian carpdensityfromtheirrespectivereaches(i.e.,highdensityreachhadhighercopynumber),andforthe mostpart,centrifugedsampleshadhighercopiesthanfilteredsamples(Table5).Detectionprobability wascalculatedbyreachforeachmethodusingtheresultsfrombothlabsforeachindividualsite.For exampleifWGL(+)andERDC(‐,)thenthesitewasconsidered(+).Detectionprobabilitiesweresimilar forthemediumandhighreaches,butcentrifuginghada26%detectionratecomparedto0%for filtrationinthelowdensityreach(Table6).Thetotallengthofthestudyreachwas2.50kmwithan averagewidthof0.12kmandatotalareaof0.30km2.Therefore,usingcentrifugationa95%detection probabilitywouldrequire10samples(i.e.,10setsoffive50mltubes)tobecollectedper2.5kmreachor 4samplesperriverkm.Toachievea99%detectionprobabilityattotalof15samplesper2.5kmor6 samplesperriverkmwouldbecollected. Forthestatisticalanalyses,thecopynumberswereaveragedforthereplicatesamplesbetweenthetwo labs.Therefore,everysitehadanaveragecopynumberforeachofthesixmarkers.Theaveragecopy numberswerethenlog10transformed,andadissimilaritymatrixwasthengeneratedbasedonEuclidean distanceforthePERMANOVA.ResultsfromthePERMANOVAshowedsignificantdifferencesbetween centrifugingandfiltrationforallthreereaches(P<0.001;Table7).Centrifuginghadsignificantlyhigher copynumbersthanfiltrationforhighandlowdensityreaches,butfiltrationhadsignificantlyhigher numbersinthemediumdensityreach(Tables5and7).Reasonsforhighernumbersinthefiltered samplesfromthemediumreachcouldberelatedtodifferencesininhibitorsbetweenreaches,orother confoundingenvironmentalvariables,butthatisbeyondthescopeofthisstudy.However,astatistical differenceinthemediumreachwherefilteringproducedhighercopynumbersisnotasrelevantina detectionprogram,sincetheoveralldetectionrateisadifferenceof96%versus100%,andbothmethods wouldprovidepositiveresultsforthisparticularreach.Sinceearlydetectionprogramsfocuson detectioninlow‐densityreaches,itisimportantthatthecentrifugationmethodwasabletodetectDNA whenthefilteringmethodwasnot.
