Imifula yaseSpain naseYurophu zibe nezinguquko eziningi ngokuhamba kwesikhathi, ikakhulukazi ngenxa yokwakhiwa kwamadamu, amaxhaphozi nezinye izingqalasizinda okuthi nakuba zibe nomthelela ekuthuthukisweni kwabantu, okuholele ekutheni izithiyo ezingathi sÃna empilweni yasemanziniEsinye sezisulu eziyinhloko izinhlanzi ezifudukayo, njenge-salmon, i-trout, ne-eel, ezithembele ekuhambeni ngokukhululeka emifuleni ukuze ziqedele umjikelezo wazo wokuphila.
Buyisela ukuxhumana komfula isibe yinto ehamba phambili ezikhungweni zokuphatha imvelo kanye nongoti bezinto eziphilayo ezinhlobonhlobo. Kulo mongo, izinhlanzi ziyadlula, eyaziwa nangokuthi izitebhisi, amarempu, noma izinto zokuwela, idlala indima ebalulekile ekubuyiseleni izindawo zokuhlala emifuleni nasekubuyiseleni izinhlobo zezilwane eziwohlokayo.
Kungani kudingeka amaphasi ezinhlanzi? Ukuhlukana kwemifula ngenxa yezithiyo zokwenziwa kuvimbela izinhlobo eziningi zezilwane ekufinyeleleni lapho zizalela khona noma zizalela khona. Lokhu kungaholela ekutheni ukwehla okukhulu kwezibalo zabantu, njengoba kuye kwenzeka ngezinhlanzi ze-salmon, ezidinga ukubhukuda zikhuphukele phezulu ukuze zizalane emanzini ahlanzekile, anomoya omuhle.
Indlela izinhlanzi ezidlula ngayo zisebenza
Un isiqephu sezinhlanzi Iqukethe uhlelo lwamashaneli, amarampu, izitebhisi noma imigudu eklanywe ngemithambeka ethambile kanye nemisinga emaphakathi ukuze izinhlanzi zikwazi ukuzungeza izithiyo. Isakhiwo Kumele ivumelane ne-morphology yomfula kanye nezinhlobo ezihlosiwe, kucatshangelwa izidingo zabo namandla okubhukuda.
Amamodeli avame kakhulu izitebhisi de peces (ngokulandelana kokugxuma okuncane noma amachibi), amarempu anamasinga alawulwayo, nama-bypasses asemaceleni, avumela umgoqo ukuba ugwenywe. Ukuphakamisa imishini ngezinye izikhathi kusetshenziswa ngisho nakumadamu amakhulu. Idizayini efanele Kubalulekile, njengoba izixazululo ezingalungiswanga kahle zingase zingasebenzi noma zibe yingozi ezilwaneni zasendle.
Imithelela emihle yamaphaseji ezinhlanzi
Ukufakwa nokuthuthukiswa kwamaphaseji ezinhlanzi kunomthelela ngqo ekuzinzeni kwabantu de peces abafudukayo. Kufakazelwe lokho ukususwa kwezithiyo nokudala imizila ephephile Bakhuthaza impumelelo yokuzala, ukufinyelela ezindaweni eziyinhloko, nokubuyiselwa kwezilwane ezisengozini.
Ezingeni le-ecology, buyisela ukugeleza kwemvelo kwemifula Ithuthukisa ikhwalithi yamanzi, ikhuphule ukuhlukahluka kwezinto eziphilayo, futhi isiza ukubuyisela imisebenzi ebalulekile yemvelo, njengokuthuthwa kwezakhi kanye nokulawulwa kwezinhlobo ezihlaselayo. Kuphinde kunciphise ukufa okuhlobene nemizamo ehlulekile yokususa amadamu, okuzuzisa kokubili izinhlobo zezilwane kanye nemvelo yomfula uwonke.
Izinselelo nekusasa ekuphathweni kwemifula
Ukuqaliswa okulungile kwe izinhlanzi ziyadlula Kudinga ukuhlela okuningiliziwe nokusebenzisana phakathi kweziphathimandla, ososayensi, onjiniyela, nabasebenzisi bamanzi. Mningi umsebenzi osasele: kulinganiselwa ukuthi kunezinkulungwane zezithiyo kule nhlonhlo ezithiya ukufuduka kwezinhlanzi, eziningi zazo azisasetshenziswa noma azisasetshenziswa.
Inselelo yile Hlanganisa ukubuyiselwa komfula ezinhlelweni zokulawulwa kwamanzi, ukutshala imali ezisombululweni ezisivumela ngempela ukuthi sibuyisele ukuhamba kwezinhlobo zezinto eziphilayo kanye nezinqubo zemvelo zemifula. Kubalulekile futhi ukuqwashisa ngokubaluleka kokugcina imifula iphila futhi ixhumekile, njengoba izinzuzo zemvelo zinomthelela eqophelweni lemiphakathi yasemakhaya nasemadolobheni.
Okuhlangenwe nakho kwakamuva kubonisa lokho uma ubheja susa izithiyo futhi udale izinyathelo ezisebenzayo, akuvikelwe nje kuphela izinhlobonhlobo zezinto eziphilayo kodwa kuvulwa namathuba okuvakasha okusimeme, ukudoba ngenjongo yokuzijabulisa, nokufundisa ngemvelo.
Ukusetshenziswa kwe izinhlanzi ziyadlula Kubalulekile ukumisa ukulahleka kwezinhlobonhlobo zezinto eziphilayo kanye nokubuyisela impilo emifuleni yethu, siqinisekise ukuqhubeka nokuphila kwezinhlobo zezilwane ezidumile njenge-salmon kanye nokuthuthukisa imvelo yasemanzini ekwazi ukumelana nezimo futhi elinganiselayo.
