I-salmon e-pink (lat. Iyisayizi encane kunazo zonke futhi imele izinhlanzi ezisabalele kakhulu zohlobo lwe-Pacific salmon (i-Oncorhynсhus).
Incazelo yesalmon ebomvana
I-salmon e-Pink noma i-salmon e-Pink iyinhlanzi enokubukeka okujwayelekile kubo bonke abameleli bezinhlanzi ezenzelwe i-Ray kanye ne-oda le-Salmoniformes.
Ukubukeka
I-salmon yase-Oceanic pink ihlukaniswa ngomhlane oluhlaza okwesibhakabhaka noma oluhlaza okwesibhakabhaka, izinhlangothi zesiliva nesisu esimhlophe... Ngemuva kokubuyela ezindaweni zokuzalela, umbala walezi zinhlanzi uyashintsha. I-salmon epinki iba mpunga ngombala ngemuva, futhi isisu sithola umbala ophuzi noma ohlaza okotshani obonakala ngokusobala. Kanye namanye ama-salmonid, i-salmon ebomvana ine-fin ye-adipose etholakala kule ndawo kusuka ku-dorsal kuya ekugcineni kwe-caudal.
Kuyathakazelisa! Isisindo esimaphakathi salmon omnyama obomvana cishe siyi-2.2 kg, kanti ubude bezinhlanzi ezinkulu kunazo zonke ezaziwa ngalezi zinhlobo kwakungu-0.76 m ngobunzima obungu-7.0 kg.
Izici eziyinhloko ezihlukanisa usalimoni obomvana ngumlomo omhlophe nokungabikho kwamazinyo olimini, kanye nokuba khona kwamabala amnyama amnyama amancanyana ngemuva nokubukeka okwenziwe ngo-V komphetho we-caudal. Inhlanzi inesiphetho sendunu, emelwe yimisebe ethambile engu-13-17. Ngesikhathi sokufudukela ezindaweni zokuzalela, abesilisa be-salmon e-pink bakha i-hump ecace bha futhi ehlukaniseka kahle endaweni engemuva, ngenxa yokuthi abamele lolu hlobo lwe-salmon bathola igama labo elingavamile.
Ukuziphatha nendlela yokuphila
I-salmon e-Pink ithanda amanzi aqandayo, ngakho-ke izinkomba zokushisa ezikahle kakhulu zokuhlala kwalezi zinhlanzi zingama-10-140KUSUKA. Lapho izinga lokushisa likhuphukela ku +260Ukusuka nangaphezulu, kunenqwaba yokufa kwesalmon ebomvana... Abamele i-oda le-Salmoniformes ngaphezulu kobusika ezindaweni lapho izinga lokushisa lamanzi lingehli ngaphansi kwe-50C. Yilezi zimo eziveza indawo ye-Kuroshio yamanje efudumele, etholakala ngasogwini oluseningizimu nasempumalanga yeJapane. Ukufuduka kwe-salmon e-pink kunwetshiwe kancane kune, ngokwesibonelo, ku-salmon ye-chum, futhi abantu abadala abavuki kakhulu emanzini omfula.
Mangaki ama-salmon abomvana ahlala
Isikhathi esifushane kakhulu sokuphila kwabamele umndeni we-salmon, esingeqile eminyakeni emithathu, kungenxa yokuthi i-salmon ebomvana ifinyelela ekuvuthweni ngokocansi ezinyangeni ezingamashumi amabili ngemuva kokungena emanzini olwandle, futhi ngemuva kokuzala kuphela empilweni yabo, abantu abadala bayafa.
Indawo yokuhlala
Inhlanzi eyi-Anadromous, okwamanje engomunye wabamele abadume kakhulu bohlobo lwe-salmon yasePacific (i-Oncorhynсhus), isabalele kakhulu emanzini asogwini olwandle lwasePacific nase-Arctic.
Kuyathakazelisa! Maphakathi nekhulu leminyaka elidlule, kwenziwa imizamo eminingana yokujwayeza i-salmon ebomvana emanzini omfula asogwini lwaseMurmansk, kepha akukho mpumelelo ebonakalayo etholakele kulo mcimbi.
Phakathi kwezinye izinto, abamele umndeni wama-salmon bahlala emaGreat Lakes eNyakatho Melika, lapho inani elincane kakhulu labantu laziswa ngengozi. E-Asia, abamele isigaba sezinhlanzi ezenzelwe iRay kanye ne-oda leSalmoniformes zisatshalaliswa kahle zaze zafika eHonshu.
Ukudla kwe-salmon e-Pink
Njengoba zikhula futhi zikhula, ama-salmon pink juveniles asuka ekudleni kweplankton nama-benthos kuya kuma-zooplankton amakhulu nezinambuzane ezahlukahlukene zasemanzini, kanye nazo zonke izinhlobo zezinhlanzi ezincane. Noma kunjalo, okuncamelayo kunikezwa:
- izibungu ze-chironomid;
- izibungu zezimpukane zamatshe nezama-mayflies;
- imidji;
- ama-copepods amancane;
- ama-harpacticides;
- ama-cumaceans;
- amphipisi.
Ngokuyinhloko ama-crustaceans ahlukahlukene nezinwele ezikhulayo zezinhlobo ezithile zezinhlanzi kusebenza njengokudla kwabantu abadala besalmon abomvana. Eshalofini, abantu abadala bangashintsha ngokuphelele badle izibungu zama-invertebrates nezinhlanzi ezinama-benthic.
Kuyathakazelisa! Kumele kuqashelwe ukuthi ngaphambi nje kokuba izinkukhu zizale, izinhlanzi ziyayeka ukondla, ngenxa yokumiswa kwezitho zokugaya kanye nokuvinjelwa kokucabanga kokudla.
Ngaphezulu kwezindawo ezijule kakhulu, ukudla kwendabuko imvamisa kuyisikwele, izibungu, izinhlanzi nezinhlanzi ezincane, kufaka phakathi ama-anchovies akhanyayo ne-silverfish.
Ukuzala nenzalo
Maphakathi nehlobo, abamele isigaba se-Ray-finned fishes kanye ne-oda leSalmoniformes baqala ukungena ngenkuthalo emanzini omfula ukuzala, okwenzeka ngo-Agasti. Zonke izici zokuziphatha zalezo zinhlanzi zijwayelekile kunoma yimaphi ama-salmonids, ngakho-ke, ngaphambi kokuphonsa amaqanda, owesifazane wakha isidleke ngendlela yokudangala ngezansi. Ngemuva kokuthi amaqanda esezalisiwe, avundiswa abesilisa, bese amaqanda engcwatshwa, futhi inhlanzi endala iyafa nakanjani.
Kuyathakazelisa! Ngenkathi yokugingqika ngasolwandle, inani elikhulu lamafry liyafa futhi lidliwe izinhlanzi ezidliwayo noma izinyoni.
Insikazi inesikhathi sokushanela cishe amaqanda angama-800-2400... I-pink salmon gazinga iqhekeza ngoNovemba-Disemba, futhi okokuqala basebenzisa izinto eziqukethwe esikhwameni se-yolk ukuze bondleke. Eminyakeni eyishumi edlule yasentwasahlobo noma ekuqaleni kwehlobo, gazinga elikhulile lishiya isidleke salo futhi, ngosizo lokugeleza kwamanzi, lishelele olwandle. Ubude babo okwamanje ngu-3 cm, futhi umzimba ubonakala ngombala we-silch monochromatic ngaphandle kokuba khona kwemivimbo eguqukayo eyisici sabantu abadala. AmaJuveniles adla izinhlobonhlobo zeplankton nama-benthos.
Izitha zemvelo
I-pink salmon caviar imane idliwe ngobuningi ngezinhlanzi eziningi, kufaka phakathi i-Dolly Varden char, char, nezinhlobo ezinjengelenok, greyling kanye ngaphandle. Ngesikhathi sokungena emanzini olwandle, ama-salmon gazinga abomvana azingelwa ngenkuthalo yizinhlanzi ezinamazinyo nezinambuzane ezidliwayo, kanye nezinhlobo ezithile zamadada zasendle nezinkukhu. Ngesikhathi sokuhlala kwabo olwandle, ama-salmon amadala abomvana abomnyama adliwa ngenkuthalo ngezinye izidalwa zasemanzini, ezimelwe imikhomo ye-beluga, izimvu zamanzi noshaka be-herring. Ezindaweni zokuzalela, amabhere, ama-otter namakhozi ayingozi ikakhulukazi ezinhlanzini ezivela emndenini we-salmon.
Inani labantu kanye nesimo sezinhlobo
Kubo bonke abamele i-salmon yasePacific, yi-salmon ebomvana ebonakala ngosayizi omncane kakhulu nenani elikhulu impela, futhi, phakathi kwezinye izinto, izinhlanzi ezinjalo ziyinto yokudoba okuthengiswayo okusebenzayo. Ngaphansi kwezimo zemvelo, kunokushintshashintsha kwemvelo impela futhi okubonakalayo enanini eliphelele le-salmon ebomvana, kodwa ingozi yokuqothulwa kwezinhlobo ezijwayelekile ze-anadromous ezingenawo amanzi angenasawoti okwamanje ayikho.
Inani lokuhweba
Inyama yesalmon epinki inezici ezinhle kakhulu zokunambitha futhi ilungele izindlela ezahlukahlukene zokupheka... I-caviar eyigugu yale nhlanzi yiyona enkulu kunazo zonke phakathi kwezinhlanzi ezingaphansi kohlobo lwe-Oncorhynсhus.
I-salmon e-Pink iyinhlanzi yezentengiselwano ebaluleke kakhulu, ehlala endaweni ehamba phambili ngokubamba phakathi kwe-salmon, naseKamchatka ukubanjwa kwayo okuvamile kungama-80%. Izindawo eziyinhloko zokubamba ama-salmon abomvana kuseyindawo esentshonalanga yeKamchatka nezindawo eziphansi ze-Amur. Ukubanjwa kwezinhlanzi eziyigugu ezentengiselwano kwenziwa ngezindlela ezingaguquguquki zolwandle kanye namanetha agelezayo. Izinkomba zokubamba eminyakeni edlule zinokushintshashintsha kwezikhathi ezithile.
