Ngemva kokubeka, abadala afe ngenxa yokuwohloka kwezicubu zabo zangaphakathi, okuqeda umjikelezo wabo wokuphila ngesenzakalo esisodwa sokuzala.
Ukudoba i-conger eel
I-conger eel iyinhlobo okubalulekile ekudobeni kwezentengiselwano futhi sporty. Inyama yayo yaziswa kakhulu ku-gastronomy ngenxa yokuthungwa kwayo okuqinile kanye nokunambitheka okunamandla. Ithathwa kusetshenziswa amasu ahlukahlukene, okuhlanganisa:
- I-Pesca con cana: Kungcono ukuthi isetshenziswe ebusuku ngokudla kwemvelo njengezicucu ze-squid noma i-cod.

Le nhlanzi ethakazelisayo iyisilwane esizingelayo esinobulwane nesibi esidlala indima ebalulekile ekulinganiseni kwesimiso sezinto eziphilayo zasolwandle. Ikhono layo lokuzivumelanisa nokujula okuhlukahlukene kanye nokuziphatha kwayo kwasebusuku kuyenza ibe isilwane esiyingqayizivele. Nakuba ngokuvamile ingavamile ukuba usongo kubantu, i-conger eel idinga izinyathelo zokulondoloza ezithembekile ukuze iqinisekise ukusimama kwayo olwandle.
