Muroti weRwizi ndiwo marudzi emhuri ye decapod crustaceans yechirongwa che Astacidea. Muviri wekenza unosanganisira:
- Iyo cephalothorax, ine zvikamu zviviri: anterior (musoro) uye posterior (thoracic), yakabatanidzwa pamwe chete. Pamusoro wepakati chikamu pane muromo wakatsvuka. Pamativi acho mumigero yayo pane zvinowanikwa zvinowanikwa kune maziso emeso. Pamberi pekenza yerwizi pane 2 mapaundi eminhenda mutsvuku, pakati payo imwe pfupi, uye imwe yakareba.
- Denga, rakaparadzana mimba, rine zvikamu zvinomwe. Mimba yemukenza ine mapaundi mashanu emagetsi, ayo mvura inoshandiswa kushambira. 6th uye 7th pairi yemakumbo emakumbo inogadzira fara caudal.
Pincers yemvura yakachena inoshandiswa kudzivirira uye kurwisa. Madzimai maduku kudarika varume uye zvikamu zvemuviri zvakakura zvakanyanya kudarika cephalothorax. Vanhurume vane zvipfeko zvine simba. Kana chirwere cherwizi chichirasikirwa nhengo, ipapo mushure mekunyunguduka kwekunyunguduka, ichakura chimiro chitsva munzvimbo yekare. Muvara wehove crayfish inogona kusiyanisa nekuda kwemamiriro emvura uye nzvimbo. Kazhinji, kenza yerwizi ine ruvara rwebhuruu-ruvara, ruvara-ruvara rwebhuruu kana ruvara rwebhuruu-ruvara.
Rwizi crayfish rinogara mumvura yakachena muEurope. Ichi chitunha chinowanikwa mumvura yakachena yakachena: munzizi, makungwa, dziva, mvura inokurumidza kana inoyerera (kusvika kusvika mamiriyoni akadzika, uye kuderera kusvika kusvika 12 m). Muroti weRwizi unoenda kunekuvhima usiku chete. Mumasikati, inotenderera mumhando dzose dzekugara-pasi pemidzi yemiti, mabwe, mabhiri uye zvimwe zvinhu zvinogona kurara pasi. Anodzivirira hugaro hwake pane dzimwe crayfish. Mvura yakachena inogona kugadzira burrows kusvika ku 35 cm yakareba Muzhizha, nzizi dzinofamba murwizi dzinogara mumvura isina kudzika, uye munguva yechando - inoenda pakadzika muvhu rakasimba, ivhu kana jecha.
Sevanhu, rwizi rwizi rwakashandiswa kubvira kare. Izvi zvinotsigirwa nemasara ezvipfuyo zvemhuka zvinowanikwa mu "mapuranga ekicheni" yeNeolithic period. Vasati vashumira, mvura yakachena inoshandiswa nekubikira mumvura yemunyu, kuwana mushure mekuita tsvuku tsvuku uye inonaka, inofadza kunhuwa. Zvokubika zvigadzirwa zvinoshandiswa patafura yakasanganiswa nemishonga chero ipi zvayo (parsley, celery, dill, etc.).
Mifananidzo ye crayfish munguva yekubika inotsanangurwa nehuwandu hweti carotenoids mavari. Mucheche kune pigment Astaxanthin, iyo yakave yakasviba yakajeka mutsvuku. Kusati kwatsvaga kurapwa muhupenyu hupenyu hupenyu hwemhuri yemagustaceans, carotenoids inosanganiswa nemaprotini, uye naizvozvo maruva emvura yakachena yakafukidzwa ibluish, greenish kana kuti tsvuku muvara. Munguva yekubikira, makemikari aya anoputika, uye yakabudiswa astaxanthin pigment inopa muviri mutema mutsvuku.
Usati wasema crayfish, inofanira kunge yakabikwa zvishoma mumvura inodziya, kuitira kuti nyama iite nyore nyore kuparadzaniswa nehombodo.
Inobatsira zvizere zvekenza yemuRwizi:
Nyama inonyanya kukosha yemukenza weRwizi inowanikwa mudumbu uye mumakumbo. Bhuku guru rinowanikwa mudumbu.
Nyama yemukenza weRwizi yakachena muvara, uye ine mazamu mashoma emasvi. Iyo ine utano hwakanyanya uye yakanakisa kuvira. Pakuumbwa kwayo, nyama yekenza ine zvakawanda zveproteine uye zvishoma nezvishoma mafuta. Nyama yechitunha ichi inoreva kudya kwepamusoro uye chibereko chinonaka, icho chinonyanya kugadzirwa uye chine nhamba huru yezvinhu zvinobatsira. Izvi zvinosanganisira: mapuroteni (kusvika 16%), calcium, vitamini E uye B12. Nyama yerwizi krisfositi ine zvishoma zveshoko cheteroti uye mafuta, uyewo makori.
Zvechokwadi, kenza yemvura haisi iyo yakanyorwa yehuwandu yenyama mukati mayo inofananidzwa nemamwe mvura yemvura yakachena yemagustaceans iyo vanhu vanoshandisa kudya. Mumunhu mukuru, pane nyama shoma. Semuenzaniso, mu kilogram ye shrimp ine ma 400 gramu e nyama, uye kilogram ye crayfish - anenge 100-150 gramu. Panguva imwecheteyo, rwizi krayfish runosvika 3-4 nguva dzinodhura kupfuura shrimps. Zvingangodaro, kushandiswa kwekrayfish kunobva pakuonekwa kwakanaka kwezvokudya zvaanoshongedza.
Kuumbwa kwenyama yekenza yemurwizi ine nhamba yakawanda sarufa, saka haifaniri kuchengetwa mualuminium cookware. Mushure mekusangana nesimbi midziyo, nyama inoshandura dema uye zvakapambwa. Inokurudzirwa kushandisa girazi.
