Redfin yaku Mongolia ndi nsomba ya banja la carp, ndi yamtundu wa skygazers. Ili ndi thupi lalitali, lopendekeka pambali, kumtunda kwa thupi ndi mdima, wobiriwira-imvi kapena bulauni-imvi, mbali zake ndi zasiliva. Zipsepse zamitundu iwiri. Ena mwa iwo ali ndi mtundu wakuda, anal, m'mimba ndi m'munsi mwa mchira ndi wofiira. Mkamwa ndi wapakati, womaliza, koma nsagwada zapansi zimatuluka patsogolo pang'ono. Kukula kwakukulu komwe kunalembedwa ndi ofufuza kumafanana ndi 3.7 kg, ndi kutalika kwa 66 cm. Kusiyana kwa skygazer ndikofunika kwambiri, pamawonekedwe ndi moyo. Redfin imakonda zigawo za mtsinje zomwe zili ndi madzi odekha komanso osasunthika. Amasunga zopinga zosiyanasiyana zamadzi, m'mphepete, matanthwe a m'mphepete mwa nyanja ndi zina zotero. Mosiyana ndi skygazer, imakonda kuya kosaya, kotero imatha kugwidwa pafupi ndi gombe. Panthawi imodzimodziyo, nsombazi zimakhala ndi moyo wambiri. Komabe, ndizotheka kukumana ndi magulu a redfin omwe akuyenda kufunafuna chakudya m'malo "osati anthawi zonse". Anthu apakati amakhala ndi zakudya zosakanikirana; mitundu yosiyanasiyana ya nyama zakutchire zam'madzi, makamaka crustaceans zotsika, ndizofala kwambiri pazakudya. Nsomba zazikulu, makamaka zotalika masentimita 50, ndi zilombo zomwe zimadya nsomba zokha. Redfin imatsogolera moyo wokhamukira, kupanga magulu ofunikira. Chinthu chosaka ndi nsomba zapansi, monga gudgeon, mpiru, crucian carp ndi zina. M'mitsinje, m'chilimwe, imakonda kudyetsa m'mitsinje yabata ndi zomera zam'madzi komanso pamadzi osefukira. Monga tanenera kale, nsomba zimasiyana pang'ono ndi zamoyo zina monga skygazer. Kukhalapo kwa redfin pamalo osungiramo madzi kumatha kudziwa momwe nsomba imawonekera pamwamba pamadzi. Mosiyana ndi mitundu ina, redfin imangowonetsa mbali ya dorsal fin kapena kumtunda kwa thupi. Nsomba imeneyi siidziwika ndi kugudubuzika pamadzi kapena kulumpha pamwamba pa dziwe. Kumayambiriro kwa nyengo yozizira, imapita kumadera ambiri ndipo ntchito yake imachepetsedwa kwambiri.
Njira zophera nsomba
Poganizira kuti redfin ndi chilombo chogwira ntchito, pakati pa zida zamasewera, kupota komanso, mwa zina, kusodza kwa ntchentche kumatha kuonedwa kuti ndikotchuka kwambiri. Kuonjezera apo, njira zachikhalidwe zowedza ndizojambula zanyambo zachilengedwe, kuphatikizapo nyambo zamoyo. Chifukwa cha kuchepa kwa ntchito, m'nyengo yozizira, palibe kusodza kwa redfin, koma mu ayezi woyamba, nsomba zimatha kujomphana ndi mitundu ina ya Kum'mawa. Redfin yaku Mongolia ndi chinthu chosodza malonda. Kuti muchite izi, gwiritsani ntchito zida zosiyanasiyana zaukonde, kuphatikiza seine. Amasiyana mkulu zophikira makhalidwe.
Kugwira nsomba pandodo yopota
M'malo okhala pakati pa Amur, Ussuri ndi malo ena osungiramo madzi, redfin ikhoza kukhala chinthu chodziwika bwino cha asodzi amateur. Poganizira kuti imakokera kumphepete mwa nyanja, ndi chinthu chopota ndi kusodza ntchentche. Pausodzi, zida zosiyanasiyana zimagwiritsidwa ntchito, zomwe mutha kuponya zingwe zopanga zapakatikati. Ngakhale kuti redfin imakoka kumunsi kwa moyo, imakhudzidwa ndi nyambo zomwe zimapita pakati pa madzi ndi pamwamba. Nsomba ilibe kukana mwamphamvu, choncho palibe zofunikira zapadera za zida. Chisankhocho chiyenera kupangidwa malinga ndi momwe nsomba zimakhalira. Tikukulimbikitsani kugwiritsa ntchito zida zapadziko lonse lapansi ndi mwayi wokhala ndi nthawi yayitali, makamaka pankhani ya usodzi m'madzi akuluakulu. Chinthu chinanso chofunikira pakusankha zida ndi nyambo chingakhale chakuti redfin, m'chilimwe, amamatira kumalo osaya, nthawi zambiri mchenga ndi osaya. Izi zimakuthandizani kuti muzitha kusodza ndi zida zopepuka.
Nyambo
Choyamba, timitsinje tosiyanasiyana tating'onoting'ono titha kukhala ngati nyambo zosodza ntchentche. Poganizira zakudya zomwe zilipo, achinyamata, plankton ndi benthos, redfin imakhudzidwa ndi nyambo zosiyanasiyana zomwe zimatsanzira tizilombo tating'onoting'ono. Pa kusodza kozungulira, nyambo zing'onozing'ono zozungulira ndi zopota zimagwiritsidwa ntchito, kuphatikizapo mitsinje yotumizidwa. Chifukwa cha kukopa kwa nsomba pansi pa madzi, redfin nthawi zambiri imagwidwa pamitundu yosiyanasiyana ya jig nyambo. Malo osodza ndi malo okhala Krasnoper ndi woimira madzi amchere ichthyofauna ku Far East. Ku Russian Federation, nsomba zimatha kugwidwa mumtsinje wa Amur. Komanso, redfin amakhala mitsinje China kuchokera Amur kuti Yangtze, komanso Khalkhin Gol ku Mongolia. Ndi nsomba yodziwika bwino yomwe ili m'madzi omwe akuima, monga Nyanja ya Khanka kapena Buir-Nur (Mongolia).
