Umnatha wokuloba luhlobo oluthile lomnatha weplastiki oqinileyo osetyenziswa ngabalobi ukubambisa nokubambisa izilwanyana zasemanzini ezinjengeentlanzi, ishrimps, noononkala emazantsi amanzi. Iminatha yokuloba ingasetyenziswa njengesixhobo sokuzihlukanisa, njengeminatha yokulwa ookrebe ingasetyenziselwa ukuthintela iintlanzi ezinkulu ezinobungozi ezifana nookrebe ukuba zingangeni emanzini abantu.
1. Phosa umnatha
Umnatha wokuphosa, okwaziwa ngokuba ngumnatha ojikelezayo, umnatha ojikelezayo kunye nenethi yokuphosa ngesandla, ngumnatha omncinci obambeneyo osetyenziswa ikakhulu kwiindawo ezinamanzi angekho nzulu. Iphoswa ngesandla, umnatha ujonge ezantsi, kwaye umzimba womnatha ungeniswa emanzini ngezitshixo. Intambo edityaniswe kwincam yomnatha iphinda irhoxe ukuze itsale intlanzi emanzini.
2. Trawl Net
Umnatha weTrawl luhlobo lwesixhobo sokuhluza esihambahambayo, esixhomekeke ikakhulu ekuhambeni kwenqanawa, ukurhuqa izixhobo zokuloba ezimilise okwengxowa, kunye nokurhuqa ngenkani intlanzi, ishrimps, unonkala, oonokrwece, kunye neemollusks kumnatha emanzini apho ukuloba. kupasiswa izixhobo, ukuze kuphunyezwe injongo yokuloba ngemveliso encomekayo.
3. Seine Net
I-purse seine sisixhobo sokuloba esinemilo emide esenziwe ngomnatha kunye nentambo. Imathiriyeli yenethi ayigugi kwaye ayigugi. Sebenzisa izikhephe ezibini ukutsala iincam ezimbini zomnatha, emva koko ujikeleze intlanzi, kwaye ekugqibeleni uyiqinise ukuze ubambe intlanzi.
4. Gill Net
I-Gillnetting ngumnatha omde omile okwemigca eyenziwe ngamaqhekeza amaninzi omnatha. Ibekwe emanzini, kwaye umnatha uvulwa ngokuthe nkqo ngamandla e-buoyancy kunye nokucwila, ukuze iintlanzi kunye ne-shrimp zibanjwe kwaye zifakwe kwi-net. Izinto eziphambili zokuloba ziyi-squid, i-mackerel, i-pomfret, i-sardines, njalo njalo.
5. I-Drift Netting
I-Drift Netting ibandakanya amashumi ukuya kumakhulu eminatha edityaniswe nezixhobo zokuloba ezimile okwemigca. Iyakwazi ukuma nkqo emanzini kwaye yenze udonga. Ngokukhukuliseka kwamanzi, iya kubamba okanye ifake intlanzi equbha emanzini ukufezekisa umphumo wokuloba. Noko ke, iminatha ekhukulisekayo iyingozi kakhulu kubomi baselwandle, yaye amazwe amaninzi aya kunciphisa ubude bayo okanye ade avale ukusetyenziswa kwayo.
