1. Semelo sa potso ea lipatlisiso 
Kgudu ya East Pacific (EP) leatherback turtle (Dermochelys coriacea) e tloha Mexico ho ya Chile, e nang le mabopo a maholo a dihlaha Mexico le Costa Rica (Santidrián Tomillo et al. 2007; Sarti Martínez et al. 2007) le libaka tsa mantlha tsa ho iphepa ka metsing metsing a lebopong la leoatle la Amerika Bohareng le Boroa (Shillinger et al. 2008, 2011; Bailey et al. 2012). Turtle ea EP ea leatherback e thathamisitsoe ke IUCN e le Kotsing e Haholo-holo, 'me ho fokotsehile ho hoholo ha palo ea tse tšehali mabōpong a maholo a lihlaha ho tlalehiloe (http://www.iucnredlist.org/details/46967807/0). Ho hakanngoa hore hajoale ho na le likolopata tse kholo tse ka tlase ho 1000 tsa EP leatherback turtles. Ho tšoenya ka mokhoa o sa reroang ha likhupata tsa EP tsa batho ba baholo le ba seng ba holile ke batšoasi ba litlhapi ba sebetsang ka har'a libaka tsa phepelo ea mefuta ena, ho latela tšusumetso e matla eo mekhahlelo ena ea bophelo e nang le eona ho matla a sechaba (Alfaro-Shigueto et al. 2007, 2011; Wallace et al. al. 2008). Liphetho ho tsoa liphuputsong tse thehiloeng boema-kepeng tse tsamaisoang lebopong la Amerika Boroa li bonts'a hore lipakeng tsa 1000 le 2000 EP leatherback turtles li ts'oaroa libakeng tsa libaka tsa ho tšoasa litlhapi tse nyane selemo le selemo, 'me hoo e ka bang 30% - 50% ea likolopata tse hapiloeng lia shoa (NFWF le IUCN/SSC. Sehlopha sa Litsebi tsa Kgudu ea Marine). NOAA e thathamisitse khupata ea leatherback ea Pacific e le e 'ngoe ea tse robeli tsa "Species in Spotlight",' me e khethile ho fokotsa ho tšoasa litlhapi e le e 'ngoe ea lintho tse tlang pele molemong oa ho hlaphoheloa ha mofuta ona. Ka Hlakubele 2012, Sehlopha sa Tshebetso sa Setsebi se ile sa bokellwa ho ntshetsapele Leano la Tshebetso la Lebatowa ho emisa le ho etsolla ho putlama ha EP leatherback turtle. Leano la Tshebetso la Lebatowa le totobatsa bohlokwa ba bohlokwa ba ho tsebahatsa dibaka tse kotsing e kgolo ya ho tshwasa dikolopata, mme ka ho qolleha le kgothalletsa katoloso ya ditekolo tsa dikpata tsa lewatleng tse itshetlehileng boemakepeng ho kenyeletsa Panama le Colombia. Ho feta moo, The Regional Action Plan e lumela hore ho shoa ka lebaka la ho tšoasa litlhapi ho hlahisa phephetso e kholo boikitlaetsong ba EP leatherback turtle, 'me e tiisa hore kutloisiso e betere ea litekanyetso tsa batho ba shoang ka mor'a tšebelisano-'moho ke ea bohlokoa bakeng sa tlhahlobo e utloahalang ea phello ea 'nete ea ho tšoasa litlhapi. mofuta ona.

2. Lipakane 
2.1. Tsebisa hore na ke lihlopha life tse sebetsanang le li-leatherback le hore na ke linako life le libaka tse nang le bohlokoa bo khethehileng bakeng sa litšebelisano tseo; hape, ho etsa lithupelo le batšoasi ba litlhapi ho arolelana liphetho tsa lipatlisiso, ho khothaletsa mekhoa e metle ea ho tšoara le ho lokolla likolopata tse hapiloeng, le ho matlafatsa likamano tsa ts'ebelisano ho tsamaisa lithuto tsa kamoso.

​
2.2. Ntlafatsa likhakanyo tsa ho shoa ha likolopata tsa leatherback ka lebaka la tšebelisano ea batšoasi ba litlhapi, le ho ngola metsamao ea leatherback turtle libakeng tse furung tsa Pacific Bochabela ho lekola libaka tse ka bang teng bakeng sa tšebelisano ea botšoasi ba litlhapi.
​
2.3. Sebelisana le matsapa a tikoloho (LaudOPO, NFWF) le NOAA ho tšoaea likolopata tsa leatherback libakeng tsa ho tšoasa litlhapi Amerika Bohareng le Boroa le ho tsebisa liqeto tsa botsamaisi mabapi le lipheo tsa phokotso ea litšokelo.

3. Mekhoa
3.1. Mokhahlelo oa pele (o ntse o tsoela pele) Re ile ra etsa liphuputso tse tloaelehileng tsa tlhahlobo ea ho tšoasa litlhapi likoung tse tharo tsa Colombia (Buenaventura, Tumaco, le Bahía Solano) le likou tse supileng tsa Panama (Vacamonte, Pedregal, Remedios, Muelle Fiscal, Coquira, Juan Diaz le Mutis). Khetho ea likou bakeng sa tsamaiso ea liphuputso e ne e ipapisitse le lintlha tsa mmuso mabapi le likepe tse kholo tsa ho tšoasa litlhapi tse sebetsang ka har'a metsi a Colombia le Panama. Ho feta moo, tlhahisoleseling mabapi le hore na lihlopha tsa likepe li sebelisana le li- leatherbacks le pokello ea pele ea likhokahano tsa litšebelisano (ka likarolo tsa GPS tse abeloang batšoasi ba litlhapi ba ikemiselitseng ho nka karolo). Lintlha tsena li tla re lumella ho lekola hore na ke lihlopha life tseo re ka sebetsang le tsona e le hore re bokelle lintlha tse qaqileng mabapi le litšebelisano. Ka ho etsa lithupelo tsa naha ka Phuptjane 2017, re sisinya ho fana ka lithupelo le lisebelisoa tsa ho khothaletsa mekhoa ea ho tšoasa litlhapi e tla eketsa menyetla ea ho phela ka mor'a ho lokoloha ha likolopata tsa leatherback tse tšoasitsoeng libakeng tsa ho tšoasa litlhapi tse lebopong la leoatle le pelagic linaheng ka bobeli.
3.2. Mokhahlelo oa bobeli Re tla sebelisa li-transmitters tsa sathelaete le ho etsa litlhahlobo tsa bophelo bo botle ka likolopata tsa leatherback tse hapiloeng libakeng tsa ho tšoasa litlhapi tsa likhoele tse telele tsa likhoele/gillnet tsa Colombia le Panama. Re tla sebetsa ka tšebelisano 'moho le bo-ramahlale ba mmuso ho tsoa Colombian le Panamanian National Fisheries Service (AUNAP le ARAP) le batšoasi ba litlhapi ba sebetsang libakeng tse kotsing e kholo ea ho tšoasa litlhapi, joalo ka ha ho bonts'itsoe ke liphuputso tse thehiloeng boema-kepeng. Litlhahlobo tsa bophelo bo botle le li-attachments tsa li-transmitter li tla etsoa, ​​ho ea ka liprothokholo tse hatisitsoeng (Harris et al. 2011; Casey et al. 2014), ka likolopata tsa leatherback tse hapuoeng nakong ea ts'ebetso ea tloaelo ea ho tšoasa litlhapi. Lisampole tsa mali li tla hlahlojoa bakeng sa mefuta-futa e itseng ka sekepeng se nang le mohlahlobi oa tlhokomelo, 'me sampole e nyane ea mali e tla hoamisoa bakeng sa tlhahlobo hamorao. Li-tag tsa PAT li tla hlophisoa hore li lokolloe sebakeng sa sehokelo sa carapacial tlas'a maemo a bontšang lefu (ke hore botebo> 1200m kapa botebo bo sa feleng bakeng sa lihora tse 24) kapa ka mor'a nako ea likhoeli tse 6. Re tla sebelisa mokhoa oa ho etsa mohlala o loketseng data e bokelletsoeng ho bapisa litšobotsi tsa 'mele tsa baphonyohi, mafu, le likolopata tse phetseng hantle tse hapiloeng leoatleng bakeng sa lipatlisiso tsa mahlale. Metsamao ea ka mor'a ho lokolloa e tla beoa leihlo 'me ho tla hlahlojoa mekhoa ea sebaka le ea nakoana ea tšebeliso ea bolulo. 4. Liphetho tse lebelletsoeng, hore na liphetho li tla ajoa joang Re tla sebelisa lintlha tsa lipatlisiso le lipalo-palo tsa mmuso mabapi le boholo le matsapa a likepe tsa ho tšoasa litlhapi ho hakanya palo ea litšebelisano tsa likolopata tsa leatherback tse etsahalang selemo le selemo libakeng tsa ho tšoasa litlhapi tse nyenyane le tsa indasteri. Papiso ea ho tšoasoa ha likolopata tsa leatherback lipakeng tsa ho tšoasa litlhapi ho tla re lumella ho hloaea litšokelo le menyetla ea ho fokotsa ho tšoasa litlhapi ka mokhoa o sa tloaelehang sebakeng sena. Ho kopanngoa ha boitsebiso ba fisioloji le boitsebiso ba boitšoaro ba ka mor'a tokollo ho tla matlafatsa bokhoni ba rona ba ho lekola lefu ka lebaka la likamano tsa batšoasi ba litlhapi. Ho lateloa ka satellite ea likolopata tsa leatherback ho tla kenya letsoho sepheong sa Leano la Ts'ebetso la Lebatooa la ho tsebahatsa mekhoa ea ts'ebeliso ea sebaka sa bolulo le monyetla oa ho kopana ha libaka le tsa nakoana tsa likolopata tsa leatherback le ts'ebetso ea botšoasi ba litlhapi Pacific Bochabela.
