I-river zebra mussel iyinhlobo ehlukile ye-bivalve mollusk, evame ukuhlala ezindaweni zokugcina ezifuywayo. Kwabadobi, yigobolondo nje. Ukuthola i-Dreissen kulula. Igobolondo laso lingunxantathu ngesimo, umbala waso uphuzi noma uluhlaza okotshani ngephethini enesimo ngendlela yemigqa ye-zigzag noma edlulayo onsundu. Ubukhulu besinki bungafinyelela ku-5cm.

Kwesinye isikhathi, ngenxa yobusilika obuphansi kanye nezimpawu zamanzi, amagobolondo aba mnyama ngandlela thile,, ambozwe “ngodaka”, angaba mnyama ngokuphelele.

Imvamisa, la mollusks athanda “ukunamathela ngakuye” amatshe, i-Driftwood, nabanye, kufaka phakathi izinto zokwenziwa zilele echibini. Kuhleliwe emakoloni. I-zebra mussel enhle yokudoba izinhlanzi ezimhlophe. Kuyaziwa ukuthi phakathi kwezitsha ezithandwayo zabahlali abangaphansi kwamanzi, ama-mollus ayindawo enhle kakhulu. Futhi hhayi kuphela abanikazi bezinsiza zomlomo ezinamandla abazithatha ngokuzithandela.

Ukudla nge-zebra mussel ngokuzithandela sekuphenduke i-scavenger enkulu, i-bream ngisho ne-roach. Ngenjabulo babubula nge-carp yakhe (i-carp) ne-catfish. Ngokomthetho, ukuqinisekiswa kwalokhu kutholakala kalula ngokubonwa okujwayelekile.

Ngakho-ke, kubhaxosi ebanjiwe noma i-scavenger, izindebe kwesinye isikhathi "zisikwa" kancane. Lokhu kungumphumela wokudla kwegobolondo. Roach enokusikeka okufanayo akuvamile. Sikholelwa ukuthi i-carp ayinqunywa nhlobo.

Inhlanzi “ibhula” igobolondo ngezindebe zayo isendaweni lapho inamathela khona futhi ngenxa yalokho ithola umonakalo ochaziwe, okuvame kakhulu ngokhokho. Kamuva, i-zebra mussel iyagwinywa futhi ihlafunwe ngamazinyo we-pharyngeal. Ngenhlanhla, “igobolondo” lemollusk liba buthaka kunalokho.

Ngaphezu komsebenzi wangempela we “nozzle”, i-zebra mussel nayo yengezwe ekudleni okuhambisanayo. Ngaphezu kwalokho, kwezinye izindawo, isengezo esinjalo sikuvumela ukuthi uvuselele ukulunywa ngokubandakanyeka kwezinhlobo ezithembekile kakhulu.

Ezindlela zokulungiselela i-zebra mussel, lokhu okulandelayo kungaphawulwa.

Owokuqala - u-clam uyasuswa egobolondweni bese efakwa isicwecwana esikhulu esincanyana. Ubulukhuni besheyithi alishisi kangako, ngakho-ke kungaba ngcono ukwenza ama-punctures ambalwa. Le ndlela isebenza ngokudoba.

Owesibili - “okuchoboza” okuncane imbumbulu, kuboshelwe kanye nezicucwana zegobolondo. Lokhu kufanelekile ukudoba ngezinketho eziningi zokubamba ezingezansi.

Okwesithathu, ukuthola ama-catfish kanye nezidumbu ezinkulu, zenza umgexo owenziwe nge-peeled noma echobozekile ye-zebra, ziqoqe ama-mollusks entanjeni yokudoba futhi ifake imbobo kuwo. Ngokuyinhloko, kungenzeka ukuthi unamathisele nje izimbaza eziningi ze-zebra kulokho okuthwetshiwe.

Ngokwemvelo, i-zebra mussel ngeke ilondoloze kwi-bezlevy uma inhlanzi ingafuni ukondla. Kepha lapho ngobuhlakani ethinta isibungu, umhlonyane wegazi, njll. isheyizi, kepha ukulunywa kweqiniso akwenzeki, i-zebra mussel izosiza ukuphuma kulesi simo.

Ngokwemvelo, isihebe sakhiwa ngamatshe ngesandla, sihlukanise nezindawo zokuhlala zabantu. Ingagcinwa ezitsheni ezivulekile ngamanzi omfula. Kuyiqiniso, akukhona ukuhlakanipha ngokukhethekile ukubeka ishelu lolwandle isikhathi eside ngokweqile. Noma kunezimo, ukuvuna kwayo ekwindla kanye nokusetshenziswa okulandelayo kokudoba ebusika, kepha “ubulukhuni” bomsindo we-nozzle kanye nobuvila bezinhlanzi akuhlali kuvumela ukuvuna okunjalo.
