Iminatha yokuloba yahlulwe ngokusebenzayo ngokweminatha yegill, iminatha yokutsala(Trawl networks), iminatha ye-purse seine, ukwakhiwa komnatha kunye nokubeka umnatha.Ukucaca okuphezulu (inxalenye ye-nayiloni ye-nayiloni) kunye namandla, ukuxhathisa okulungileyo kwempembelelo, ukuxhathisa i-abrasion, ukuqina kobungakanani be-mesh kunye nokuthamba, kunye nokuqhekeka okufanelekileyo kobude (22% ukuya kwi-25%).Ijijwe yi-monofilament kunye ne-multifilament (ngomnatha)
Umnatha wokuloba ugxininise okanye i-monofilaments icutshungulwa ngokulukwa (i-raschel, i-knotless net), unyango olusisiseko lobushushu (amaqhuqhuva asisigxina), ukudaya kunye nonyango lobushushu besibini (ubungakanani obulungisiweyo bemesh).
Ingasetyenziselwa ukuloba ngomnatha, ukutroli, ukuloba ngemikhonto, ukuloba ngesithiyelo kunye nokuseta ukuloba.Okanye ube yimathiriyeli ekrwada yokuveliswa kweebhokisi zenetha, iikheji zokuloba kunye nezinye izinto zokubambisa.
Iminatha esetyenziswa kwimveliso yokuloba iquka inethi zokuloba, isipajiiminatha ye-seine,phosa iminatha,iminatha esisigxina kunyeiikheji.Iitrawls kunye ne-purse seines yiminatha enzima esetyenziselwa ukuloba kushishino lokuloba elwandle.Ubungakanani be-mesh bu-2.5 ukuya kwi-5 cm, ububanzi bentambo yomnatha bu malunga ne-2 mm, kwaye ubunzima bomnatha buziitoni ezininzi okanye iitoni ezininzi.Ngokuqhelekileyo, ipere ye-tugboats isetyenziselwa ukutsala iqela lokuloba ngokwahlukileyo, okanye isikhephe esilula sisetyenziselwa ukutsala intlanzi kwiqela kunye nokulijikeleza.Iminatha yokuphosa yiminatha elula yokubambisa imilambo namachibi.Ubungakanani be-mesh bu-1 ukuya kwi-3 cm, ububanzi bentambo yomnatha bu malunga ne-0.8 mm, kunye nobunzima beekhilogram ezininzi.Iminatha ezinzileyo kunye neekheji zinyuswe ngokusesikweni inetha ezizinzileyo kumachibi, amadama okanye amatheku.Ubungakanani bomgangatho buyahluka ngokweentlanzi eziphakanyiswayo, kwaye iintlanzi zigcinwa kwindawo ethile yamanzi ukuze zithintele ukuba zibaleke.
