Amanethi okudoba ahlukaniswa ngokusebenzayo abe amanetha adonsayo, amanetha adonsayo(amanetha okudoba), amanetha e-purse seine, ukwakhiwa kwenetha kanye nokubeka inetha.Ukukhanyela okuphezulu (ingxenye yenetha inayiloni) namandla, ukumelana nomthelela omuhle, ukumelana nokuhuzuka, ukusimama kosayizi wemeshi nokuthambile, nokuqhekeka okufanele (22% kuya ku-25%) kuyadingeka.Isonte nge-monofilament kanye ne-multifilament (enethi)
I-concentrate inetha lokudoba noma ama-monofilaments acutshungulwa ngokwelukwa (i-raschel, inetha elingenafindo), ukwelashwa okuyisisekelo kokushisa (amaqhuqhuva angaguquki), ukudaya kanye nokwelashwa kokushisa kwesibili (usayizi wemeshi ongaguquki).
Ingasetshenziselwa ukudoba ngamanethi e-drift, i-trolling, i-spearfishing, ukudoba ama-bait kanye nokudoba okusethiwe.Noma ube yimpahla eluhlaza yokukhiqiza amabhokisi anetha, amakheji okudoba nezinye izinto zokubamba.
Amanethi asetshenziswa ekukhiqizeni ukudoba ahlanganisa amanetha okudoba, isikhwama semaliamanetha e-seine,phonsa amanetha,amanetha alungisiwe kanyeamakheji.Ama-trawl kanye ne-purse seines angamanethi anzima asetshenziselwa ukudotshwa ezindaweni zokudoba olwandle.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 iqembu labadobi ngokwehlukana, noma isikebhe esilula sisetshenziselwa ukuheha izinhlanzi eqenjini futhi lisizungeze.Amanetha aphonsa amanetha alula okubamba imifula namachibi.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 aphakanyiswa ngokuzenzela amanetha angashintshi emachibini, emachibini noma kumatheku.Ubukhulu bezinga buyahlukahluka kuye ngezinhlanzi ezikhuliswayo, futhi izinhlanzi zigcinwa endaweni ethile yamanzi ukuze zingaphunyuki.
