Further,thelocalauthoritiesandfishermenwishedtoensurethatthedolphinswerenotadverselyimpactedbydolphinwatchingandcontactedresearchersinChinaandHongKongforadvise.
Sincethattime,researchteamsfromtheQinzhouBayChineseWhiteDolphinsResearchCenterofPekingUniversity,PRChina,andstaffandassociatesoftheWorldWideFundforNature(WWF)inHongKonghavebeenconductingvisualsurveysonthearea'sdolphinpopulation.

ApartfromthepopulationwhichdwellswithinthePearlRiverEstuary(JeffersonandLeatherwood,1997;Parsons,1997;Porteretal.
,1997;Porter,1998;Jefferson,2000;Porter,2002),untilveryrecently,littlehasbeenknownofdistributionwithintheregion(Perrinetal,1996;WangandHan,2006).
ThereisconsiderableconcernoverthesurvivalofthisandothercetaceanspecieswithinSoutheastAsiaduetotheaccumulativeimpactsfromfisheriesactivities,heavyshiptraffic,coastaldevelopmentandpollution.
TheSanniangBaypopulationofS.

TheotherpopulationsresideinLeizhouandthePearlRiverEstuary(GuangdongProvince),XiamenHarbour(FujianProvince)andwesternTaiwan.
Allofthesepopulationsaresmallandthedistancebetweeneachisconsiderable,suchthatitislikelythateachpopulationisisolatedfromtheother.

InXiamenHarbour,comparisonsbetween1994and2004populationabundanceestimatesindicatethatthepopulationhashalvedinthattime(HuangandLiu,2006;Yangetal,2006).

TheMinistryofAgriculture,thePeoplesRepublicofChina,recentlyheldaworkshopwhichaimedtocompileallrecentinformationonthedistributionandstatusofIndo-PacifichumpbackdolphinsinChinesewatersandtodevelopacommonstrategyfortheeffectiveconservationofthespecieswithinChina.
Itwasproposedthatthelevelofconservationconcernforthevariousareasshouldbe1)GuangdongProvince,includingthePearlRiverandLeizhouBay.
2)FujianandTaiwan,specificallytheTaiwanchannel.
3)SanniangBay,GuangxiProvince(Wang2006).
Thatis,itwasgenerallyagreedthatthedolphinpopulationswhichresideinSanniangBaywasleastatriskandthosepopulationsinthePearlRiverEstuary,XiamenHarbourandTaiwanwereimpactedbycontinuedandincreasingdevelopmentoftheseareas.

SinceMay2004,regularsurveysoftheentirebayindicatethatthedolphinsoccupyacoreareaofapproximately120km2andrarelyoccurinwaterdepthsgreaterthan10m(Fig.

Boatsurveys:twotypesofboatsurveyswereconducted;systematicandopportunistic.

Duringbothtypesofsurveys,thetimeandlocationofeveryencounterwithdolphinswasrecordedusingaGPS.
Detailedinformationoncondition,agecategoryandbehaviourwasalsonoted.
Whenpossible,highresolutionimagesofthedorsalfinareaandindividualcolourationpatternsweretaken.
Thisresultedinthecollectionofmorethan10,000imagesandavarietyoffeatureswereusedtoclearlyidentifyindividuals(Fig.

Theminimumsizeofthepopulationisestimatedas98,fromcountingtheabsolutenumberofindividualsthroughphoto-identificationtechniques.
These98individualscomprise52juveniles(calvesandadolescents),46adultsandsub-adults(usingthecriteriaoutlinedbelow).

DiscussionAsappearsusualforthisspecies,thepopulationofdolphinsthatresideinSanniangBayissmallandinhabitsacoreareaofshallowhabitatthatisinfluencedbyfreshwaterinputfromnearbytworivers.
UnlikeotherpopulationsofSousachinensisinSoutheastAsia,thedolphinsofSanniangBayappeartobehealthy,withalargeproportionofyoungindividuals(>50%)andapparentlowmortality.
Thereislittleevidencethatfishinggearsignificantlyimpactsthedolphins,e.

Similarly,vesselcollisionsareunknowninthisareaofsouthernChina,incontrastwithotherpopulations(VanWaerebeeketal.

Assuch,theestuaryadjacenttoSanniangBayhasbeenallocatedforindustrialdevelopment.
