I-Roosterfish

Esihlokweni sanamuhla sizokwazi ngokujulile uhlobo lwasolwandle olubizwa ngokuthi I-Roosterfish. Ingenye yezinhlanzi ezinamandla kakhulu olwandle futhi iyakhanga njengenselelo yokudoba ezemidlalo. Njengoba unamandla amakhulu, kunzima ukudoba uma ungenalo ikhono noma unekhono lenduku. Ngakho-ke, njengendlela yokuzihlola, le nhlanzi iyinhlanzi impela. Igama layo lesayensi ngu Lepidorhombus boscii.

Ngaphezu kwamandla ayo amahle kakhulu nokuheha kwayo njengenhlanzi yokudoba, kule ndatshana ungafunda konke ngebhayoloji, izici, indlela yokuziphatha, njll. Ngabe ufuna ukufunda kabanzi nge-roosterfish? Kumele uqhubeke ufunde.

Izici eziyinhloko

Njengaku- izinhlanzi ezigwedlwayo Inomzimba omkhulu ngokwanele okwenza ikulungele ukudoba. Inesisindo esingamakhilogremu angama-80 futhi inesayizi yomzimba wamamitha ama-3. Lesi sibonelo esihle siyadingeka impela, yize kuliqiniso ukuthi lezi zinyathelo ziyahlukahluka impela. Ngokuya ngendawo yokusabalalisa lapho ikhona, izoba nkulu noma ibe ncane.

Umzimba ngokuvamile mude futhi mkhulu unesici esikhethekile. Futhi icindezelwe engxenyeni edlule. Ikhanda layo lide futhi ingemuva liqinile futhi liyindilinga. Umlomo unesimo se-oblique futhi umakwe umugqa odlula ngamehlo womabili ume mpo.

Lapho singena emlonyeni wayo, sithola umhlathi onamazinyo amancane aphumele ngaphandle futhi unama-gill raker angu-18 enhla yomhlathi. Ekhoneni eliphezulu le-gill line-12 yalezi brachispines.

Ngokuqondene nombala, uyethula i-hue eluhlaza okwesibhakabhaka exutshwe ne-hint yesiliva umzimba wonke. Amabala enawo emhlane nasesifubeni enza ukuthi yehluke kalula kalula. Inama-slats ama-2 asuka emaphethelweni omgogodla futhi anwebeka ekugcineni kwempuphu kanti elinye lisuka emgogodleni kuye ekugcineni komsila.

Ibanga nendawo yokuhlala

Lezi zinhlobo zihlanganyela indawo yokuhlala ne- inhlanzi kalamula. Imvamisa ibonakala ezindaweni zokuhlala eziseduze nezindawo ezisogwini. Uhlala njalo efuna ukuhlala eduze nemifula ukuze aphephele ezindaweni ezinesihlabathi esiningi. Ngenkathi le nhlanzi iphephela ezindaweni ezinesihlabathi esiningi, inhlanzi kalamula ihamba nawe ngenkathi isolwandle.

Kwezinye izikhathi itholakale isungulwe emaphethelweni emabhishi, emachwebeni kanye nasemachibini. Lapho besengamantombazane futhi bengakakhuli ngokuphelele, bangahlala emanzini angajulile ngaphandle kwezinkinga.

Isikhathi sonyaka lapho ukubona nokubamba izinhlanzi okujwayele ukuvela kuso kuvame ukuba phakathi nenyanga kaJuni kuya kuSepthemba. Ngenxa yokunyakaza okunekhono elingakwenza, iyakwazi ukubonakala ezindaweni ezinjengemilomo yemifula, izindawo ezinamadwala nezindawo ezinamagagasi anamandla.

Ukudla kwe-Roosterfish nokuzala

I-Roosterfish inejubane elikhulu lapho idabula olwandle. Ngenxa yekhono lakhe lokuzingela angadla anhlobonhlobo de peces ezinobukhulu obuhlukahlukene phakathi kwawo sithola inkunzi noma inhlanzi yethusi.

Ilukuluku elibaluleke kakhulu ukuthi uma lezi zinhlanzi zikhona ngezikhathi lapho izinga lokuzingela liphansi bese ziqala ukulamba kakhulu, zigcina sezisebenzisa ubuzimuzimu. Banezela ekudleni kwabo ngezinhlobo zezinhlobo ezifanayo ngaphezu kokusebenzisa kabi ama-sardine nezinhlanzi ze-koi, abaziphishekela ngokuphikelela baze babanjwe futhi badliwe.

Ukukhwelana kwenzeka phakathi kwezinyanga zikaJulayi kuze kube sekupheleni kukaFebhuwari. Yisikhathi lapho ukuzala sekuvuthondaba. Ukubekwa kwamaqanda kungenzeka ngezindlela eziningi. Eyokuqala isesikhathini kusukela ngasekupheleni kuka-Agasti kuya kuNovemba. Owesibili uqala ngoFebhuwari kuya ku-Ephreli. Lesi sikhathi sincike esikhathini lapho bekuhlangene khona futhi lapho isikhathi sokwakhiwa kwamaqanda sesidlulile.

Ukukhulelwa kweRoosterfish kungaphandle. Njengezinhlobo zayo eziningi, izalela ezindaweni ezingajulile njengoba zizizwa zivikeleke ngokwengeziwe. Ngokuvamile babheka izindawo eziseduze nolwandle lapho kunokujula okuncane. Amafry aqanduselwa emaqandeni anokulingana okuphelele futhi ahlala eduze nomphezulu aze afinyelele ekuvuthweni.

Njengoba bekhula, bahlangabezana nochungechunge lwezinguquko. Isici siyahluka futhi kancane kancane silahlekelwa yilowo mlinganiso oshiwo ngenhla. Lapho ethatha isinqumo sokuya olwandle, ukwenza lokho ukuze azimise isikhathi esiyiminyaka okungenani emibili.

Ukudoba imidlalo yeRoosterfish

Lezi zinhlanzi ziphumelela kakhulu emhlabeni wezokudoba kwezemidlalo. Okudingwa kakhulu ngabadobi yileyo nselelo enzima ukuyinqoba futhi lokho kubenza babonise amakhono abo okudoba. Inani eliphakeme kakhulu lesilinganiso sokudoba kwalesi silwane senzeka ezinyangeni zika Mashi nango-Ephreli, lapho zingazaliswanga ngokugcwele.

Ukuhweba ngenhloso yokuthengisa inyama yabo kuyenziwa kusetshenziswa inqubo yokudonsa phakathi kwamamitha ayi-100 kuye kwangama-500 ukujula. Ukumaketha kwanda njengoba kwaduma ngokudoba kwezemidlalo. Izinhlobo ezincane kakhulu ezidotshiwe zingama-25 cm. Enye inqubo esetshenziselwe ukubanjwa kwayo yi-longline. Kubaluleke kakhulu ukuthi izindawo lapho kune-boom enkulu yokudoba kwazo zilungele ukunciphisa umthelela kwezemvelo okuwudalayo.

Izindawo ezihambelana neNyakatho ye-Atlantic yilezo lapho kwenzeke khona ukuthwebula izifanekiso ezinkulu ezinama-140 cm ubude. Kodwa-ke, eMedithera kunezinye izinhlobo ezinosayizi omncane. Izindawo abadotshwa kuzo kakhulu ziseGulf of Cádiz, oLwandle lwaseCantabrian naseNyakatho-ntshonalanga.

Inkinga eyenzeka, njengenjwayelo, kulolu hlobo lokudonsa ngamanethi, ukuthi ezinye izinhlobo zezilwane ziyatholakala. de peces lapho okuhlosiwe kuyi-roosterfish. Ngaphezu kwalokho, ibhubhisa i-marine morphology kanye nezinhlobo ze-algae.

Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngale nhlanzi edumile.
