El conger eel (Conger conger) Ihove yakaita seeel ndeyemhuri yeCongrida. Inoratidzwa nemuviri wayo wakareba uye wenyoka, inofanana ne eel, kunyangwe ivo vari vemhuri dzakasiyana. Ihove huru inogona kukura kusvika 3 mamita uye kurema kupfuura 70 makirogiramu, kunyange zvazvo mienzaniso yakajairika inosiyana pakati 1 uye 1,5 metres pakureba nepakati 8 uye 15 kg zvekurema.
Habitat uye kugoverwa kwe conger eel
Conger eel ihove inoparadzirwa zvakanyanya munzvimbo dzakasiyana dzemugungwa. Kuvapo kwayo kwakajairika mu mahombekombe egungwa reAtlantic Ocean, kubvira Norway kuenda kuSenegal, kusanganisira North Sea uye Baltic Sea. Mariri Mediterranean Iyo imhando yakajairika, kunyangwe muGungwa Dzvuku inongowanikwa munharaunda yayo yekumadokero.
Kana kuri kudzika kwainogara pairi, conger eel ine a yakafara bathymetric kugovera. Inogona kuwanikwa kubva mumvura isina kudzika ye inopfuura mita imwe chete munzvimbo dzine matombo kusvika kupfuura 1.000 metres yakadzika, kunyanya panguva yekubereka kwayo.
Maitiro nemaitiro
Konger eel imhando tsika dzeusiku uye dzekuva wega. Masikati, hove idzi dzinogara dzakavanda mukati kutsemuka uye kutsemuka kwepasi pematombo, mapako epasi pemvura kana zvivakwa zvekugadzira zvakaita se wrecks (zvasara zvezvikepe zvakanyura). Usiku, vanobuda mudzimba dzavo kuti vanovhima.
Pasinei nekuonekwa kwayo kwehasha, conger eel Kazhinji haina ngozi kuvanhu; Nekudaro, kumwe kurwiswa kwakanyorwa kana vachinzwa kutyisidzirwa kana kukwezvwa nezvinhu zvinopenya. Munzvimbo umo diving yakajairika, conger eel inogona kusvika kujaira kuvapo kwevanhu uye kunyange kugashira zvokudya zvakananga kubva mumaoko evapfuri.
Conger eel feeding
Hove iyi a carnivorous predator iyo inovakira kudya kwayo zvakanyanya pa:
- Hove: Inovhima mhuka idiki pane pachayo, senge sardines, mackerel kana cod.
- cephalopods: Inodya squid, octopus uye cuttlefish.
- Crustaceans: Inogona kubata magakanje nemalobster.
Iyo conger eel yekuvhima nzira inosanganisira Enda kunze usiku mukutsvaga mhuka dzakavanzwa pakati pematombo kana pasi pegungwa. Shandisa kurwisa kamwe kamwe uye rushaya rwayo rune simba rwakashongedzerwa mazino akapinza kuti vabate nokubvarura mhuka dzavo.
Kubereka uye kutenderera kwehupenyu
El Kutenderera kwekubereka kwe conger eel Inoratidzwa nechiitiko chimwe chekubereka (chinozivikanwa se cycle) semelparous) Pakangosvika kukura kwepabonde, conger eel inoita kutama kwenguva refu kumvura yakadzika kuti ibereke. Kutama uku kunogona kuva zvose chinjikira (kufamba nzendo refu) sekuti vertical (kusvika pakadzika zvakanyanyisa).
Madzimai anogona kurara pakati 3 uye mamiriyoni masere mazai, iyo inoyangarara mumvura yakadzika kusvika yachochonya. Kubudirira kubva pakuchechenya kusvika kuchikamu chevadiki kunopfuura nematanho akati wandei:
- Semilarva: Diki uye pachena, inogona kuyera kusvika 15 masendimita.
- Leptocephalus: Mashizha-akafanana, anenge 13 masendimita, dzakanyanya kufanana nemakonye eel.
- Vechidiki: Inotora fomu yevakuru, ine cylindrical body, inoyera inenge 8 masendimita.
Mushure mekurara, vanhu vakuru kufa nekuda kwekuderera kwezvinyama zvavo zvemukati, kupedzisa hupenyu hwavo muchiitiko chimwe chekubereka.
Conger eel hove
Konger eel imhando zvakakosha mukuredza kwekutengesa uye zvemitambo. Nyama yaro inokosheswa zvikuru mugastronomy nekuda kwekusimba kwayo uye kunhuhwirira kwakanyanya. Inotorwa uchishandisa nzira dzakasiyana-siyana, kusanganisira:
- Angling: Inonyanyo shandiswa husiku nezviredzo zvechisikigo senge zvidimbu zve squid kana cod.
- Gillnet Fishing: Nzira inonyanya kushandiswa mukutengesa hove.
- Kuredza pasi pemvura: Inoitwa neharpoon munzvimbo dzine matombo panowanzovanda conger eel.
Kukosha kwezvakatipoteredza uye mamiriro ekuchengetedza
Nzondo inotamba a basa rinokosha mugungwa reecosystem, sezvo inodzora vanhu de peces uye ma<em>crustaceans munzvimbo dzavanogara. Nekudaro, mune dzimwe nzvimbo kuvepo kwayo kwakadzikira nekuda kwe kubata hove and the kuparara kwenzvimbo Marine.
Maererano ne International Union for Conservation of Nature (IUCN)Iyo conger eel haina kunyorwa sezvipenyu zviri mungozi, asi zvakakosha kudzora kushandiswa kwayo kudzivirira kuderedzwa kwakanyanya muhuwandu hwayo.
Ihove inonakidza iyi imhuka yakabira uye inoparadza inoita basa guru pakudzikama kwezvipenyu zvemugungwa. Kugona kwayo kujairana nekudzika kwakasiyana uye hunhu hwayo hwehusiku hunoita kuti ive mhuka yakasiyana. Kunyangwe isingawanzo kutyisidzira vanhu, conger eel inoda matanho ekuchengetedza ane hunyanzvi kuti ive nechokwadi chekugara kwayo mumakungwa.
