Mhenderekedzo yekumabvazuva kweGran Canaria inotarisana nemhedzisiro yechiitiko che rufu de peces paAquanaria neEcoaqua Izvi zvave nemhedzisiro huru pakurima kwemvura uye kushandiswa kwemahombekombe akati wandei. Izvo zvakatanga seanomaly muhunhu hwemhuka zvakakonzera kufa kwakanyanya muMelenara (Telde) uye mumatangi eTaliarte.
Kuongorora kwekutanga kubva kuYunivhesiti yeLas Palmas de Gran Canaria kunongedza kukuvara kwakanyanya kwegill uye kutonga kunze kwechirwere chetachiona kana cheparasitic. Panguva imwecheteyo, zviremera zviri kuongorora kana pangangodaro paine chimwe chinhu chiri shure kwechiitiko ichi. kuraswa zvisiri pamutemo kwehydrogen sulfide (H2S), fungidziro iri kuongororwa naSeprona uye Hofisi yemuchuchisi.
Chii chinozivikanwa kusvika ikozvino
Mumakeji ekuberekesa eAquanaria, ari pamhenderekedzo yeMelenara beach, kambani yakashuma a chiitiko chekunze nekufa kusina kujairika uye inofungidzirwa kurasikirwa kwehupfumi kweanosvika mamirioni gumi nemashanu emaeuro, mushure mekukanganisa angangoita makumi mana muzana ekugadzirwa kwayo kwegungwa munzvimbo mbiri.
Zvichakadaro, Ecoaqua University Institute (ULPGC), ine zvivakwa padyo nechiteshi cheTaliarte, yakanyora kufa kwehove dzinenge mazana mashanu, nhamba inomiririra inenge 5% yebiomass inochengetwa mumatangi avo ekuberekesa.
Ecoaqua matekiniki anotsanangura pateni inoenderana ne kufema kukanganisa mumienzaniso yakakanganiswa. Mishumo yeSainzi inoratidza kukuvadzwa kwezvimiro zvegill izvo zvinodzivirira kuchinjika kwakajairika kweokisijeni pakati pemvura nemuviri wehove.
Iyo Yakanyanya Specialized Aquaculture uye Biotechnology Service (SABE-ULPGC) inosimbisa padanho renhoroondo kurasikirwa kwe epithelial architecture uye necrosis mumapuleti egill, zvakawanikwa zvinoenderana nekutadza kufema kwakanyanya muvanhu vanotambura zvakanyanya.
Neruzivo rwuripo, iyo ULPGC inotonga kuvapo kwezvirwere kana utachiona sechikonzero chekufa. Mabheti asara paEcoaqua anoratidza kugadzikana, uye shanduko yavo iri kutariswa zvakanyanya.
Kutsvakurudza kuri kuitika
Ongororo yemasangano inotarisa pakuona kana pakanga paine a kuparara kwemakemikari iyo yakasvika munzvimbo yakapoteredza Telde neMelenara. Purezidhendi weGran Canaria Island Council akaratidza kuti zviratidzo zvinonongedzera kuzvinobvira H2S kubudaNekudaro, mavambo uye mabasa anoramba asina kusimbiswa kwepamutemo.
Pakati pezviitiko zviri kuongororwa pane sarudzo ye kuputika kana chiitiko mukubuda kwepasi pemvura iyo ingadai yakapinza tsvina mugungwa. Cabildo (Island Council) yakaratidzawo kuti zvimisikidzo zvekuchenesa mvura yetsvina hazvisi pasi pekutariswa nekuda kwekutonga kwakasimba.
Nguva yenguva inosanganisira yambiro yekutanga ye kuvapo kunoshamisa mumvura uye kuchinja kamwe kamwe mumaitiro ehove. Masangano ane chekuita akaendesa magwaro ehunyanzvi kuSeprona (basa rekuchengetedzwa kwezvakatipoteredza reCivil Guard) uye Hofisi yemuchuchisi wePublic Prosecutor kuti ideredze kutevedzana kwezviitiko uye zvingangoitika zvekuteuka.
Iyo Cabildo pachayo yakachema a kusarongeka zvakanaka uye kushingaira Mhinduro yekutanga yakanga isina kukwana pasinei nekutanga yambiro zviratidzo zvekuputika kusati kwakanganisa mapurazi ehove. Kutsoropodza uku kunosimbisa kukosha kwekuvandudza masisitimu eyambiro ekutanga uye manejimendi emasangano.
Muchirevo chechinyorwa chino, manejimendi akasimbisa kudzora kunaka kwemvura uye kutariswa kwemaoceanographic parameters muchikamu chemahombekombe chakakanganisika, ichimirira mhedzisiro inozojekesa chinokonzeresa.
Impact pamhenderekedzo yegungwa uye chikamu
Kuuya kwe organic zvinosara uye hwema Chiitiko ichi chakakonzera kuvharwa kwenguva pfupi kwemahombekombe akati wandei kumabvazuva nekumaodzanyemba kwechitsuwa. Dzimwe nzvimbo dzakavhurwazve mushure mekugadzirisa kudiki, kunyangwe kutariswa kwakachengetwa munzvimbo dzakanyanya kukanganiswa.
Kune Aquanaria, kukanganisa kwehupfumi kwakakosha, ne fungidziro yekurasikirwa inoda kusvika mamirioni gumi nemashanu — tisingasanganisire mari yekutarisira zvigadzirwa nemarara —. Iyo kambani inosimbirira kuti inozviona sebato rakakuvara uye yakanyorera zviri pamutemo kutaurirana uye zvichemo kune vane kodzero.
Munharaunda yemagariro, chikamu chakamutsiridza gakava pamusoro pe kuenzanisa pakati pezvekurima negungwa nemhenderekedzo yegungwanemapoka evavakidzani uye ezvezvakatipoteredza anoda humwe hutongi uye pachena. Tourism, injini yehupfumi yechitsuwa, yakakanganiswawo ne kuvharwa kwepakati yegungwa.
Hurumende yechitsuwa yakazivisa a chenjedzo yechiitiko chekusvibiswa kwegungwa mazuva mushure mekufa kwepamusoro, izvo zvakabvumira kurongeka kuri nani kwesampling, kubviswa kwezvisaririra, uye kuchengetedza mapuroteni evashandisi nevashandisi.
Makambani uye nzvimbo dzekutsvagisa dzakawedzera kuongorora kwezvakatipoteredzaOkisijeni yakanyungudika, tembiricha, inogona kuderedzwa sarufa makomisheni, uye kutsvaga makemikari anotariswa. Kutarisisa uku kunotarisa kutarisisa maitiro asina kujairika emvura anogona kukanganisa hutano hwehove.
Mamiriro azvino uye matanho anotevera
MuTaliarte, Ecoaqua inotaura kuti iyo Kufa kwamira uye kuti mamwe mabhechi anochengetedza akajairwa paramita, aine zvidzoreso zvezuva nezuva uye ongororo yekuwedzera kuona kudzoreredzwa kwehurongwa.
Mitsetse yebasa yakanangana nekuyambuka Oceanographic data ine histological uye makemikari mhedzisirokuitira kuti chiitiko chacho chigadziriswe nenzira yakarurama uye vector yekupinda yeagent iyo ingadai yakakuvadza branchial tissue inogona kugadziriswa.
Vakuru vakadaidzira kusimbaradzwa kwe kudzivirira mukubuda uye chero zvivakwa zvinokwanisa kufambisa zvinoyerera mugungwa, pamwe nekutanga yambiro mapuroteni anobvumira kukurumidza kupindura kana anomalies aitika zvakare.
The aquaculture sector inosimbirira pakuda govana data munguva chaiyo pakati pehutongi, nzvimbo dzesainzi nevashandisi, kutora matanho ekukurumidza mukupindura zviratidzo zvekuderera kwemvura munzvimbo dzakaoma dzakadai seMelenara neTaliarte.
Nekuferefeta kwakavhurwa uye ongororo ichienderera mberi, nyaya yacho inopenda mufananidzo wakajeka: acute branchial kukuvara muhove dzinobva kuAquanaria neEcoaqua, kushaikwa kwezvirwere zvinozivikanwa, zvaiva nemigumisiro muEcoaqua uye pfungwa yesangano pakuona kana kuteuka kweH2S kunotsanangura chiitiko chacho nemigumisiro yacho pamhenderekedzo.
