Summary'of'sawfish'work'taking'place'in'Mexico,'Central'and'South'America.'!

Two!sawfish!species!–!the!smalltooth!and!largetooth!sawfishes!(Pristis&pectinata!and!P.&pristis)!–!are!known!to!have!occurred!historically!in!Caribbean!and!Central!American!(Atlantic)!coastal!seas,!whilst!
only!the!largetooth!sawfish!is!known!from!the!eastern!Pacific.!The!current!status!of!sawfishes!in!the!
waters!of!Mexico,!Central!America!and!the!west!coast!of!South!America!is!poorly!understood.!Until!
recently,!little!upHtoHdate!information!was!available!from!these!regions!but!happily,!since!2014,!
numerous!research!projects!have!developed!to!address!these!data!gaps.!Many!of!these!projects!are!
multiHcountry!collaborative!efforts,!which!facilitates!the!sharing!of!resources!and!expertise.!What!
follows!is!a!summary!of!the!projects!that!have!shared!information!on!their!research!and!
conservation!activities!with!the!SSG,!but!if!you!are!working!on!sawfishes!in!Mesoamerica!or!South!
America!and!don’t!see!your!project!mentioned!here,!please!do!get!in!touch!!
!
In!Mexico,!Océanos!Vivientes!AC!is!conducting!a!nationwide!survey!of!historical!and!current!
presence!of!sawfishes,!in!order!to!evaluate!the!conservation!status!of!sawfishes!in!Mexico.!The!team!
hopes!to!work!towards!a!change!in!Mexican!legislation!relating!to!sawfishes.!Océanos!Vivientes!is!
also!collaborating!with!Conservation!International!to!develop!sawfish!research!in!Colombia.!
!
MarAlliance!is!working!in!Belize,!Cuba,!Guatemala,!Honduras!and!on!the!Caribbean!coast!of!Mexico.!
Their!work!on!sawfishes!is!part!of!a!broader!programme!which!involves!working!closely!with!fishing!
communities!to!monitor!marine!megafauna,!especially!elasmobranchs.!They!hope!to!assess!the!
current!existence!of!sawfishes!in!each!of!their!study!regions,!document!historical!occurrence,!
distribution!and!local!uses!of!sawfishes,!and!identify!strategies!to!encourage!the!recovery!of!any!
remaining!sawfish!populations.!!
!
In!Peru,!Planeta!Océano!launched!a!sawfish!research!programme!in!early!2015,!involving!a!training!
programme!which!was!run!in!collaboration!with!Protect!Africa’s!Sawfishes.!Following!the!training,!
course!participants!and!Planeta!Océano!staff!conducted!interviews!at!numerous!fishing!ports!and!
landings!sites!in!northern!Peru,!and!interviews!will!be!conducted!further!south,!later!this!year.!Very!
recent!captures!of!largetooth!sawfish!have!occurred!in!northern!Peru,!including!one!adult!caught!
and!released!alive!in!February!2015.!Planeta!Océano!has!also!built!collaborative!links!with!teams!in!
Ecuador,!El!Salvador!and!Costa!Rica,!supporting!them!to!collect!data!on!sawfishes!using!similar!
methods,!and!developing!community!awareness!activities!and!educational!materials!on!sawfishes,!
to!be!used!throughout!the!region.!Planeta!Océanos’!collaborators!at!the!Universidad!Laica!Eloy!
Alfaro!de!Manabí!(Ecuador),!led!by!Dr.!Rigoberto!RosasHLuis,!have!already!conducted!429!interviews!
with!fishermen!throughout!Ecuador.!The!most!recent!capture!of!a!sawfish!there!was!in!2014,!in!San!
Lorenzo,!northern!Ecuador.!!
!
Fundación!Talking!Oceans!and!the!Smithsonian!Institution!is!conducting!sawfish!research!in!Costa!
Rica,!Panama,!Colombia!and!Ecuador.!They!aim!to!assess!the!current!distribution!and!conservation!
status!of!sawfishes!in!the!ETP,!as!part!of!a!wider!project!to!identify!and!map!elasmobranch!critical!
habitats!and!assess!MPA!effectiveness.!Fundación!Talking!Oceans!are!working!with!a!number!of!
collaborators!including!Marviva,!WWF,!USAIDHBIOREDD,!Universidad!de!Costa!Rica,!Playa!Tortuga,!
Malangwai,!SINAC,!PRETOMA,!Universidad!de!Panama,!ARAP,!Planeta!Océano!and!NAZCA.!!
!
Central!and!South!America!are!also!key!regions!for!sawfish!conservation!for!one!particular!reason!–!
the!cockHfighting!industry.!CockHfighting!is!a!very!popular!pastime!in!many!Central!and!South!
American!countries,!and!since!the!midH1970s,!sawfish!rostral!teeth!have!been!the!preferred!source!
of!‘spurs’!–!the!sharp!spikes!which!owners!attach!to!the!feet!of!their!bird!in!order!to!inflict!damage!
on!the!opponent.!Concern!has!grown!within!the!cockHfighting!industry!as!sawfish!rostra!have!
become!more!difficult!to!obtain!and!the!price!of!rostral!teeth!has!increased!significantly.!However,!
some!cockHfighting!associations!are!now!working!to!ban!the!use!of!spurs!made!from!rostral!material!
and!to!encourage!the!use!of!artificial!spurs.!In!Peru,!Planeta!Océano!is!conducting!interviews!with!
members!of!these!association,!in!order!to!assess!the!frequency!with!which!sawfish!teeth!are!still!
used!as!spurs!and!to!better!understand!how!cockHfighting!associations!can!encourage!their!members!
to!use!alternative!materials.!There!may!be!the!potential!to!develop!outreach!materials!that!can!be!
used!throughout!the!Americas!in!countries!where!cockHfighting!is!popular,!in!order!to!minimise!any!
further!threat!to!sawfishes!via!the!demand!for!rostral!teeth.!!
!
The!collaborative!nature!of!sawfish!research!in!this!region!is!a!wonderful!example!of!how,!through!
communication!and!sharing!of!resources,!numerous!small!research!projects!can!result!in!effective!
data!collection!and!better!geographic!cover.!This!collaborative!approach!is!also!creating!links!
between!NGOs,!researchers!and!government!organisations!which!will!enable!a!smoother!transition!
to!the!next,!equally!important!phase!of!this!work:!developing!a!regional!conservation!strategy!for!
sawfishes,!in!line!with!the!IUCN’s!Global!Sawfish!Conservation!Strategy!(Harrison!&!Dulvy!2014).!
