1.Tsala umnathaindlela
Le yeyona ndlela ixhaphakileyo yokuloba.Iminatha ngokubanzi ifuna ubude bomnatha bumalunga ne-1.5 ububanzi bomphezulu wedama, kwaye ukuphakama komnatha kumalunga nokuphinda-phindwe kabini ubunzulu bedama.
Iingenelo zale ndlela yokuloba:
Eyokuqala luhlu olupheleleyo lweentlanzi ezivela echibini, ezinokuhlangabezana neemfuno zabathengisi beentlanzi abahlukeneyo.
Okwesibini, kwinkqubo yokuzoba umnatha, udaka olungaphantsi kunye namanzi e-pool ashukunyiswa, nto leyo edlala indima yesichumiso samanzi kunye ne-aeration.
Kakade ke, le ndlela ikwaneengxaki ezicacileyo:
Eyokuqala kukuba inkqubo yokutsala umnatha ukwahlula iintlanzi inde.
Oku kuneziphumo ezininzi ezinganqwenelekiyo.
Eyokuqala kukuba amandla okusebenza aphezulu kakhulu, kwaye ubuncinane abantu abaninzi bayafuneka ukuze bagqibezele umsebenzi wokutsala.
Okwesibini kukuba intlanzi yenzakala lula, enokubangela izifo zeentlanzi.
Ukongeza, i-phenomenon ye-hypoxia kunye neentlanzi ezifileyo zinokuthi zenzeke ngenxa yexesha elide kakhulu ngexesha lokusebenza kokwahlula iintlanzi.
Okwesibini, izinga lokubanjiswa kwezinye iintlanzi alikho phezulu.
Ngokukodwa kwixesha lobushushu obuphezulu kunye namanzi apheleleyo, izinga lokubamba i-carp eqhelekileyo, i-crucian carp kunye ne-grass carp iphantsi kakhulu, ngoko ngokuqhelekileyo kukholelwa ukuba indlela yokutsala umnatha ifanelekile ngakumbi "kumanzi atyebileyo" kunye ne-carp yesilivere bighead carp njengeyona ntlanzi iphambili.Intlanzi” ichibi lokuzalela.
Ngoku, ukuphendula iingxaki kwinkqubo yokutsala umnatha, iindlela ezimbini zokuphucula ziye zaziswa:
Eyokuqala kukusebenzisa iminatha emikhulu yokutsala umnatha.Iminatha esetyenziswayo imiselwa ngokwemigaqo yokuloba.Iintlanzi ezingahambelaniyo nemigaqo edwelisiweyo zihluzwa ngaphandle kwe-mesh kwaye aziyi kungena kwi-intanethi, ngaloo ndlela zinciphisa ixesha lokusebenza kwaye zithintele ukwenzeka kwe-hypoxia.Le ndlela nayo ayinakuphepheka kwingozi yeentlanzi, ngakumbi i-herring kunye nengca ye-carp ephakathi kweminwe kunye neentlanzi zabantu abadala zihlala zixhomekeke ekuxhonyweni kwi-net.Ezi ntlanzi zinethi zonzakala ngokubanzi kwigill kwaye ngokusisiseko azikwazi ukuphila., ixabiso lezoqoqosho lokuthengisa ngokulambatha nalo lisezantsi kakhulu.
Okwesibini kukusebenzisa indlela ye-fish-collecting purse seine, oko kukuthi, iiyure ezi-2 ukuya kwezi-3 ngaphambi kokutsala umnatha, yongeza amanzi amatsha echibini, ukwenzela ukuba iintlanzi ezininzi echibini zigxininiswe kwindawo entsha yamanzi.Ukuloba kunokugqitywa kwikona lamanzi, elinciphisa kakhulu ixesha lokutsala umnatha.Ekubeni iqhutywe kwindawo entsha yamanzi, ayiyi kubangela imeko ye-oxygen-deficially and dead fish.Nangona kunjalo, le ndlela ifanelekile kuphela ukusetyenziswa kwinqanaba lokuqala xa kukho amanzi amancinci echibini.Ngeli xesha, intlanzi ye-pond inempendulo ebonakalayo ekuvuseleleni kwamanzi amatsha, kwaye i-purse seine isebenza kakuhle.Ehlotyeni xa amanzi egcwele, intlanzi yasechibini ayiphenduli ngamandla ekukhuthazeni kwamanzi amatsha., ngokufuthi abafumani miphumo mihle kakhulu.
2. Ukuphakamisa umnathanokuhambisa ucingo
Le yindlela yokubambisa eyakhuthazwa emva kokusetyenziswa kokutya okuhlanganisiweyo ukufuya.
Umgaqo wokuloba ngomnatha:
Umnatha wokuphakamisa ungowodidi lwenethi, oluphuculweyo ukusuka kumnatha oshukumayo.Xa uloba, umnatha ufakwa phantsi kwendawo ye-bait kwangaphambili, intlanzi ifakwe kwi-net yokunyusa ngokutya, kwaye umsebenzi wokuloba uqhutyelwa ngokusebenzisa umgaqo wokulinganisa.Ngamafutshane, ukuphakamisa ukuloba ngomnatha kukutshonisa i-polyethylene okanye inethi zenayiloni emanzini ekufuneka ebanjwe kwangaphambili.
Izinto eziluncedo zale ndlela yokuloba:
Umsebenzi ulula kwaye ixesha lokusebenza lifutshane kakhulu, kwaye yonke inkqubo ithatha kuphela malunga nemizuzu engama-40, ngaloo ndlela inciphisa umonakalo kwintlanzi.Ukongezelela, phantsi kweemeko zemozulu eziqhelekileyo, le ndlela inezinga eliphezulu lokubambisa intlanzi yokutya.Ngokubanzi, ubuncinci i-60% ukuya kwi-70% yeentlanzi ezityayo zinokuphakanyiswa emnatheni rhoqo, ezilungele ukubamba iimfuno ezinkulu nezincinci zokuzala.
iindlela ezithile:
Qala ubeke umnatha wokuphakamisa kunye nenethi ezantsi kwendawo yokutya.Unokuyeka ukutyisa usuku ngaphambi kokuba inetha iphakanyiswe.Xa umnatha uphakanyiswa, uya kuvakala kangangemizuzu eli-15 uze emva koko ukhuphe umatshini ukuphembelela intlanzi elambileyo ukuba iqokelele, uze usebenzise umatshini wokutyisa.Ukutya, ukuhlambalaza imizuzu elishumi (kuxhomekeke kwimeko), ngeli xesha intlanzi iya kubamba ukutya, intlanzi iya kugxininisa umnatha wokuphakamisa kunye nomnatha, kwaye emva koko umnatha uphakanyiswa, umnatha uphakanyisiwe okanye umnatha uphakanyiswa. washukuma ukubamba iintlanzi.
Ewe kunjalo, indlela yokuphakamisa umnatha kunye nokuhambisa umtya nayo ineziphene zayo:
Okokuqala, kukho izithintelo kwizinto eziza kubanjwa.Isebenza kuphela ngokutya iintlanzi, kwaye ukubamba i-carp yesilivere phantse i-zero.
Okwesibini, ngokucacileyo ichatshazelwa yimozulu.Ngenxa yokuba intlanzi kufuneka ihlanjululwe ngokutya, ngentsasa yeentsuku ezishushu okanye ezinemvula, injongo yokuqokelela iintlanzi ihlala ingakwazi ukufikelela ngenxa yokungabikho kwe-oxygen.
Okwesithathu, kukho imfuneko ephezulu kubunzulu bamanzi echibini.Emachibini anobunzulu obungaphantsi kweemitha ezili-1.5, intlanzi kaninzi ayikwazi ukugxila ekutyeni ngenxa yempembelelo yokunyusa umnatha kunye nomnatha ophantsi kwechibi, ukwenzela ukuba umsebenzi wokubamba ngamanye amaxesha awukwazi ukugqitywa kakuhle..
Okwesine, ixesha lokulungiselela lide kwinqanaba lokuqala.Ukuze kuphunyezwe umphumo ofanelekileyo wokuloba, umnatha wokuphakamisa kunye nomnatha kufuneka ubekwe ezantsi kwendawo yokutya kwiintsuku ezi-5 ukuya kwezi-10 kwangaphambili ukuvumela ukuba iintlanzi zilungelelane.
3.Ukuphosa umnatha
“Ukuphosa umnatha” luhlobo lomnatha lokuloba olwalusetyenziswa mandulo ngaphambili.Umntu omnye unokugqiba umsebenzi wokuloba ngokuphosa umnatha emanzini ekwiphenyane okanye elunxwemeni.Ngalo lonke ixesha umnatha uphoswa, kuthatha malunga nemizuzu emi-5 ukuya kwe-10, kwaye indawo yokuloba ixhomekeke kwinqanaba lomsebenzisi, ngokubanzi malunga nama-20 ukuya kwi-30 square metres.
Iingenelo ezinkulu zale ndlela:
Igcina abasebenzi, ngokuqhelekileyo ngabantu aba-2 kuphela abanokusebenza kakhulu, kwaye iintlanzi ezibanjwe ngale ndlela ziphelele kwiindidi.
Eyona ntsilelo yayo inkulu:
Okokuqala, ayikukhuthazi ukuloba ngezinga elikhulu.Ngokubanzi, inokubamba kuphela i-50-100 yeekati okanye ngaphantsi kakhulu ngexesha ngalinye.
Okwesibini kumonakalo omkhulu kwintlanzi ebanjwe, kuba umsebenzi wokwahlula intlanzi yale ndlela kufuneka igqitywe kwisikhephe okanye elunxwemeni, eyonakalisa kakhulu iintlobo zeentlanzi echibini.
Okwesithathu kukuba olu hlobo lomsebenzi lunobugcisa obuphezulu kwaye kaninzi kufuneka lwenziwe ngabasebenzi abakhethekileyo.Ngoko ke, ixabiso lokunyusa le ndlela liye laba lincinci kwaye lincinci.
Ngolu hlalutyo lungentla, wonke umntu unokugqiba indlela yokuloba ngokweemfuno zabo zokwenyani.Amachibi alawulwa ziintlanzi zamanzi anamafutha kufuneka abanjwe ikakhulu ngokutsala iminatha.Emachibini asekelwe ikakhulu kulimo oluxutyiweyo lwesondlo, ngokuqhelekileyo kungcono ukuhambisa iminatha kunye nokuphakamisa iminatha.Kwamanye amachibi amancinci abantu abadala okanye ukuloba ikakhulu ukuzonwabisa kunye nokuzonwabisa.Kwi-Chi, indlela yokuphosa umnatha ikwayindlela enokwenzeka kunye nesebenzayo yobugcisa.
