hove,mambure ekuredza.Kubata hove yakakosha yekuvaka zvinhu.Zvinopfuura 99% zvinogadziriswa kubva kumagetsi ekugadzira.Kune kunyanya nylon 6 kana yakagadziridzwa nylon monofilament, multifilament kana multi monofilament, uye fibers dzakadai se polyethylene, polyester, uye polyvinylidene chloride inogona kushandiswawo.Mambure anoshandiswa mukugadzira hove anosanganisira trawl net, purse seine net, cast net, fixed net.Trawls uye purse seines mambure anorema anoshandiswa mukubata hove mugungwa.Saizi yemambure ndeye 2.5 kusvika 5 cm, kureba kwetambo yemambure inenge 2 mm, uye huremu hwemambure matani akati wandei kana gumi nematani.Kazhinji, matugboat maviri anoshandiswa kukweva nekudzingirira boka rekuredza zvakasiyana, kana igwa rakareruka rinoshandiswa kukwezvera hove muboka nekurikomberedza.Mambure ekukanda mambure asingaremi ekubata hove munzizi nemumadziva.Iyo mesh saizi ndeye 1 kusvika 3 cm, dhayamita yetambo yemambure inenge 0.8 mm, uye huremu hwemambure makirogiramu akati wandei.Fixed mambure nemakeji mambure akagadzika etsika dzekugadzira mumadhamu, madhamu kana mabheji.Ukuru uye matauriro anosiyana zvichienderana nehove dziri kusimudzwa, uye hove dzinochengetwa mune imwe nzvimbo yemvura kuti dzisapukunyuka.Mambure okuredza anoita zvakawanda.
Nekuvandudzwa kwehove, zvinhu zvekuredza nekuvhima hazvisi hove chete, asi maturusi ekuredza ari kufambirana nenguva.Mambure ekuredza anopatsanurwa kuita mambure egill, mambure ekudhonza (trawl net), purse seine mambure, kuvaka mambure nekukandira mambure.
Mambure ehove anowanzo shandiswa anoiswa se:dhonza mambure, mambure ekukukurwa,namatira mambure.Inodiwa kuve nekujeka kwakanyanya (chikamu chenaironi mesh) uye simba, yakanaka kukanganisa kuramba, abrasion kuramba, mesh dimensional kugadzikana uye kupfava, uye kurebesa kwakakodzera panguva yekuzorora (22% kusvika 25%).Iyo inogadziriswa ne monofilament, multifilament yakamonyoroka shinda (ine knotted net) kana monofilament warp weaving (raschel, inova isina-knotted net), imwe kupisa kurapwa (fixed nodule), dhayi uye yechipiri kupisa kurapwa (fixed mesh saizi).Zvigadzirwa zvekuruka mambure ekuredzesa zvakanyanya 15-36 tambo dze210-denier naironi, polyester multifilament uye ethylene monofilament ine dhayamita ye0.8-1.2 mm.Kuruka nzira dzinosanganisira kuruka, kumonyorora uye kuruka.
Ndezvipi zvinonyanya kushandiswa nemambure ekuredza?
1. Mambure ekuredza ndiwo midziyo yekugadzira yevabati vehove, inogona kushandiswa kubata hove, shrimps uye magakanje pasi pemvura.
2. Mambure ekuredza anogonawo kushandiswa sechishandiso chekudzivirira, semambure ekudzivirira shark, ayo anogona kushandiswa kudzivirira hove huru dzine ngozi dzakadai semashaki.
3. Mambure ekuredza anogona kugadzira chimiro chekuona.
