Kune mamiriyoni emhando de peces mugungwa uye nzira dzakawanda dzekushambira kune imwe neimwe. Kune vasingazive kushambira zvakanaka, vamwe vanotuhwina zvisina kujairika uye vamwe vane kumhanya kunoshamisa. Nhasi tichataura nezvehove ine nzira yekushambira inoshamisa zvechokwadi. Zviri nezve seilfishfish. Iine dorsal fin yayo ine hukuru hwakakura, hove iyi inogona kushambira nekumhanya kwazvo ichitsvaga chayabata kana kutiza mhuka dzayo.
Kana iwe uchida kuziva zvese zvine chekuita nehove iyi, ramba uchiverenga 🙂
Sailfish hunhu
Sailfish, ine zita resainzi Istiophorus albicans, yakawanikwa kekutanga muna 1792 uye inoonekwa sechisikwa kubva kuAtlantic Ocean. Iyo inozivikanwawo se marlin hove. Anofunga vamwe imwe yehove yakanakisa iyo yatinogona kuwana mumakungwa nemakungwa kutenderera pasirese.
Kune imwe subspecies iyo inogara muIndia uye Pacific nyanza uye inonzi Istiophorus platypterus. Dzese mhuri dzine bhuruu kana grey mavara uye chena dumbu. Mhando yeAtlantic idiki.
Imwe peculiarity yehove iyi ndiyo mhuno yayo. Iine chimiro chisina kujairika, chinobata kusvika padanho. Iyo yakafanana nesabata rakapinza. Ihove iyi painenge ichishanda, zvinoshamisira kuti inogona sei kushambira nekumhanya kwakanyanya ichitsvaga chayabata. Nekuda kwayakaita morphology, inogona kucheka kuburikidza nemvura nekureruka kunoshamisa. Naizvozvo, inogona kusvika pakumhanya kukuru.
Yekutanga dorsal fin ndicho chinhu chikuru chinoita kuti ive yakasiyana nedzimwe de peces, ine pakati pe37 ne49 mwaranzi. Chechipiri chemushure chipedzi idiki uye chine maranzi matanhatu kana masere chete. Muswe chinhu chakakosha chaunoshandisa kusvika pakumhanya zvakanyanya sezvo uchibatanidzwa necaudal peduncle yakasimba uye ine simba.
Iwe unogona kuwana mienzaniso yesafishfish inorema zana makirogiramu. Chinhu chakasarudzika ndechekuti ivo vakatenderedza 50 kg.
Habitat
Ihove iyi inogara mumvura yekumusoro yegungwa. Ivo havawanzogara munzvimbo dzakadzika uye vanogara vachisarudza mvura inodziya uye inodziya. Munzvimbo mavanogoverwa, zviri nyore kwazvo kuwana mhuka dzavanobata. Nekuda kwekumhanyisa kwavanofamba, basa ravo rekutsvaga chikafu harina kunyanya kuoma.
Atlantic seaffish inosiyana nhanho yavo zvichienderana netembiricha yemvura uye mune dzimwe nguva mamiriro ekutungamira uye simba remhepo. Pakunyanyisa kwehuremu hwayo (zvese kuchamhembe nekumaodzanyemba) inoonekwa chete mukati memwedzi inodziya, sezvo ichida mvura inodziya. Shanduko munzvimbo dzavanogara dzinonyanya kukonzerwa nekutama kwevakabata kune dzimwe nzvimbo. Naizvozvo, kuti varambe vachipa chikafu, vanofanirwa kufamba.
Ivo anowanzo kuwanikwa munzvimbo dzinodziya uye dzakakwirira pamusoro peiyo thermocline. Kana ichifanira kutama, inozviitira kumvura iri padyo nemhenderekedzo. Kupisa kwayo kwakanaka kuri pakati pe21 kusvika 29 degrees. Pane dzimwe nguva, mienzaniso yevaduku yakawanikwa de peces kufamba nechikepe muGungwa reMediterranean avo vakarasika mukati menzendo dzavo dzokutama.
Kune rimwe divi, iyo Indian-Pacific seaffish inowanzo kuwanikwa munzvimbo dzinotonhora uye dzinopisa dzemakungwa ese epasi. Kugoverwa kwaro kunopisa, asi kunogona kuwanika munzvimbo dziri kuEquator. Rudzi urwu rwunowanikwa munzvimbo dzese dzemahombekombe enzvimbo dzakadzikama, kunyangwe dzichigona kuwanikwa munzvimbo dziri pakati pemakungwa. Iwo epipelargic marudzi. Izvi zvinoreva kuti ivo vanoshandisa yakawanda yehupenyu hwavo hwevakuru mudunhu repamusoro reiyo thermocline.
Zvokudya
Ihove iyi inodya nyama zvachose uye inoonekwa seimwe yezvikara zvine hunyanzvi mumakungwa. Hapana mubvunzo kuti ndiyo inomhanyisa pane ese anodziya uye akadzikama emvura.
Kazhinji inodya squid, octopus, tuna nehove dzinobhururuka. Inogona kushandisa muromo wayo kubvisa maseru de peces chechikoro chose uye nenzira iyi zvinoita kuti vanyanye kubatwa. Vanokwanisa kunyura kusvika pamamita makumi matatu kudzika, asi vanosarudza kuita izvi vari pedyo nepamusoro kuti vabatsirwe nechiedza chezuva. Iri padyo nemakona emakorari kuti ive nekuona kwakakura kwenzvimbo uye kukwanisa kukona mhuka yayo.
Maitiro
Sailfish ndeye yega yega mhuka (saka kureruka kwayo mukuenderera mberi kwekutama uchitsvaga mhuka). Kashoma kuvaona vari mumapoka, kunyangwe pane dzimwe nguva vanogona kuonekwa vari mumapoka madiki kuitira kuvhima.
Iyo mhando inoronga uye kuyedza iyo nzvimbo kutanga isati yatanga kunovhima kudzivirira zvinogona kuitika.
Vanhurume nevanhukadzi vane hunhu hwakafanana, kutenderedza mhuka uye kumanikidza chikoro kuvhara. Iko kukasira kuri kukurumidza uye kwakaringana, imwe neimwe inotungamirwa nekutumirwa kunoshamisa kweiyo dorsal fin, iyo inopfuura nekaviri chimiro chemuvhimi.
Kuberekerwa
Iko kubereka kwefishfish kune kupokana kwakawanda. Mukadzi anobereka kakawanda mugore rimwe chete. Iyo nzvimbo yavanosarudza yekudyara kazhinji inzvimbo iyo tembiricha iri kutenderera 26 degrees Celsius. Vanowanzo zviita kutenderedza kumahombekombe. Kune yega yega yekuisa iyo inoita mukadzi inokandira anodarika miriyoni mazai ayo anokandwa mudrift. Mukono, kana mazai aburitswa, anobva asimudza huwandu hwemazai.
Kubva pamazai ayo anokwanisa kusangana nembeu, tumachira tudiki tunobuda izvo zvinoramba zvichingoyangarara pamusoro, zvichiva nyore kubatwa nezvikara. Naizvozvo, pamamiriyoni emazai anoburitswa nemukadzi, mashoma chete ndiwo anokwanisa kurarama kuti akure uye ave vanhu vakuru.
Vechidiki fry vane kukurumidza kukurumidza kusimukira saka, kana ivo vachikwanisa kurarama padanho rekutanga apo ivo vari nyama nyowani yezvikara, ivo vanokwanisa kusvika kune yavo nhanho yevakuru. Machende avo ari zvizere zvizere pavanosvika masendimita mashanu pakureba.
Mwedzi inonyanya kugadzirwa iri pakati paKurume naGumiguru. Kana hove dzava vanhu vakuru, vavengi vadzo vanowanzove hove huru dzakadai sehaki.
Neruzivo urwu unogona kudzidza zvakawanda pamusoro peimwe yehove dzinoshamisa kwazvo mumakungwa.
