Amanethi okudoba ahlanganisa amanetha adonsayo, amanetha akhukhulekayo, namanetha anenduku.Amanethi okudoba ayizinto zokwakha amathuluzi okudoba.Ngaphezu kwama-99% acutshungulwa emicu yokwenziwa.Kukhona ikakhulukazi inayiloni 6 noma inayiloni eguquliwe enayiloni, i-multifilament noma i-multi monofilament, futhi imicu efana ne-polyethylene, i-polyester, ne-polyvinylidene chloride nayo ingasetshenziswa.
Amanethi asetshenziswa ekukhiqizeni ukudoba ahlanganisaamanetha okudoba, isikhwamaamanetha e-seine,phonsa amanetha,amanetha alungisiwe kanyeamakheji.Amanethi ama-trawl kanye ne-purse seines angamanethi anzima asetshenziswa ezindaweni zokudoba zasolwandle.Ubukhulu be-mesh buyi-2.5 kuya ku-5 cm, ububanzi bentambo yenetha bungaba ngu-2 mm, kanti isisindo senetha singamathani amaningana noma amathani amaningi.Ngokuvamile, izikebhe ezimbili ezidonsayo zisetshenziselwa ukudonsa nokujaha iqembu labadobi ngokwehlukana, noma isikebhe esilula sisetshenziselwa ukuyengela izinhlanzi eqenjini futhi lisizungeze.Amanethi aphonsa amanethi angasebenza kalula okudoba emifuleni nasemachibini.Ubukhulu be-mesh bungu-1 kuya ku-3 cm, ububanzi bentambo yenetha bungaba ngu-0.8 mm, kanti isisindo senetha singamakhilogremu amaningana.Amanethi angaguquki kanye namakheji angamanethi angashintshiwe esiko lokwenziwa emachibini, kumachibi noma kumatheku.Ubukhulu kanye nezincazelo ziyahlukahluka kuye ngezinhlanzi ezikhuliswayo, futhi izinhlanzi zigcinwa endaweni ethile yamanzi ukuze zingaphunyuki.
Izinto zokusetshenziswa zenethi elukiweyo ziyimicu eyi-15-36 yenayiloni engu-210-denier, i-polyester multifilament kanye ne-ethylene monofilament enobubanzi obungu-0.8-1.2 mm.Izindlela zokuluka zihlanganisa ukuluka, ukusonta nokuluka i-warp.
Amanetha okudoba esimanje acutshungulwa ikakhulukazi nge-polyethylene, inayiloni nezinye izinto zokusetshenziswa.Inomjikelezo wempilo omude kanye nekhono eliphezulu lokudoba, futhi ihlukaniswa ngezindlela ezihlukene zokusetshenziswa.Isibonelo, phonsa amanetha (amanetha esandla, amanetha enziwe ngesandla)asetshenziswa ekudobeni kwendabuko, amanetha okudoba asebenzisa izikebhe njengamandla, amanetha e-gill (manethi amathathu,purse seines) ngamameshe ahlukene abamba izinhlanzi ngamagill.Lamanetha enziwe ngamameshi anobukhulu obuhlukene nemicu yezinto ezihlukene zezinto zokudoba ezihlukene.Ngesikhathi esifanayo, njengoba kuthuthukiswa amanetha okudoba, kuye kwakhiqizwa amathuluzi ahlukahlukene okudoba, njengamakheji okudoba namanetha anama-engeli amane asetshenziswa ngokuvamile amathuluzi okudoba.
