Sticklebacks imhuri yehove ine magenera akati wandei ane marudzi anosvika gumi nemasere. Idzi ihove duku, dzinoratidzwa nemaitiro akasiyana uye mararamiro. Vanogona kusiyana mune morphological maficha kubva kune mumwe nemumwe, asi ese ane spines pamberi peiyo dorsal fin. Vanoshandisa mizongoza iyi kuzvidzivirira. Mukuwedzera, dzimwe tsvimbo dzine spikes padivi redumbu, pamwe chete nemapfupa emapfupa, nezvimwewo nhovo yedumbu. Siyanisa marine, mvura yakachena uye yakanamatira inogara mumvura ine brackish. Hove dzinosiyana kwete chete munzvimbo yekugara uye chitarisiko, asiwo mumafambiro. Mvura yakachena inofarira mararamiro echikoro, uye mugungwa, zvimiti zvakanamatira zvinoungana mumapoka makuru chete panguva yekuberekesa. Ukuru hwemhando dzakawanda hunobva pa18-7 cm. Marine marudzi anogona kusvika 12 cm. Nekuda kwehukuru hwavo, stickleback yakaoma kurongedza se "trophy hove". Pasinei neizvi, inoparadza uye inoonekwa sechikara chinoshanda. Ichthyologists inotaura kuti stickleback ine hutsinye uye kazhinji inorwisana nevavakidzani muhupenyu hwavo hwemazuva ose, tisingatauri mwaka wekubereka. Hunts kubva pakuvandira. Mhando dzakasiyana dze stickleback dzinowanikwa munzvimbo dzakawanda uye dzinogona kubatwa ne-by-catch mumwaka yese. Muchikamu cheEurope cheRussia, 20-4 marudzi anosiyaniswa. MuKronstadt, chivezwa chakagadzirwa - "chiyeuchidzo kune yakakombwa stickleback", iyo yakaponesa zviuru zvehupenyu muLeningrad yakakombwa.
Nzira dzekubata stickleback
Stickleback inogona kubatwa pamhando dzakasiyana siyana, kunyangwe padiki raramo. Kunyanya kuibata, sekutonga, anglers - vanoda vanodzivisa. Chikonzero hachisi hukuru chete, asiwo mitsipa yemamwe marudzi, ayo anogona kukonzera kucheka kunorwadza. Nechikonzero chimwe chete, stickleback haiwanzo shandiswa sechirauro mhenyu kana kucheka. Zvakadaro, kana iri kuunganidzwa kwehove munzvimbo yekuredza, inogona kubatwa zvakabudirira zvese nechando uye giya rezhizha. Vechidiki vanoredza vanowana mufaro unokosha kubva pakubata stickleback. Kudyisa kunoita kuti hove iyi imhanyire kunyange iri pachiredzo chisina chinhu. Kwete "kunakidza" kubata hove kunogona kuitika panguva ye "kushaya kuruma", padziva rechando, pakubata dzimwe hove. Munguva yechando, stickleback "inokohwewa" kune zvakasiyana-siyana zvegiya, zvose pasi, uye kugutsurira uye kuzununguka. Muchirimo, hove dzinobatwa pachishandiswa chinyakare chakayangarara uye nechepasi.
Zviredzo
Muzhizha nemuchando, hove dzinobatwa pazviredzo zvemhuka, kusanganisira fry. Zvichienderana nenharaunda uye reservoir, panogona kunge kune maitiro avo. Asi nekupa makaro uye basa rehove iyi, unogona kugara uchiwana chirauro chemuromo. Dzimwe nguva unogona kushandisa nzira dzakagadziridzwa - chidimbu chefoiri uye zvichingodaro.
Nzvimbo dzekuredza uye dzekugara
Ichthyologists vanofunga kuti stickleback inokurumidza kupararira mhuka. Mumamiriro ezvinhu akanaka, inogona kushingaira kuwedzera nzvimbo yayo yekugara. Mamwe masayendisiti anopokana kuti kuvhurika chete ndiko kunodzora kupararira kwehove iyi: vanowanzodya pwere dzemarudzi avo. Mhando dzakasiyana-siyana dze stickleback dzinowanikwa mumabheseni anenge ose emakungwa eRussia, asi muSiberia neFar East, hove, kazhinji, dzinonamatira kumvura yegungwa uye brackish. Mukuwedzera, iyo stickleback inogara munzizi huru dzeSiberia uye inogona kupararira kusvika pakati. Iyo gungwa stickleback inogara munzvimbo yemahombekombe, haiumbe yakakura. Mhuka dzemvura yakachena dzakajairika, kunze kwenzizi, mumadhamu nemadhamu, uko dzinogara dziri mapoka makuru.
Kubereka
Kusiyana, zvakakodzera kugara pane stickleback, semhando, nekuda kwekubereka. Mukuwedzera kune chokwadi chokuti hove dzinodzivirira vana, dzinovaka matendere chaiwo kubva kune zvinomera zvemvura, izvo zvivakwa zvakakomberedzwa zvine nzvimbo mukati. Murume anovaka uye anorinda dendere, panguva ino haakwanisi kudya nekuda kwekuchinja kwehupenyu muhurongwa hwekudya. Hadzi inokandira mazai gumi nemaviri. Vechidiki, mukuvandudza, vanogara mukati meimba iyi kwenguva yakareba (inenge mwedzi). Vasati vabereka, varume vanochinja ruvara, marudzi akasiyana-siyana nenzira dzakasiyana, asi inova yakajeka.
