Kusarudza nzvimbo nokuda pakuvaka dziva, kufungawo chaiwo zviri:

• kwakaita nzvimbo yacho;
• unhu uye Kuronga ivhu;
• Inzwi, uye mvura unhu.

Zvakanyanya Kunaka Panguva Yepamuviri kuti muviri mvura kwakadaro vaiona ukuru 0,9-2 M kurutivi rwezasi uye 1,8-3,5 M kuchamhembe, apo hasha Winters zvichibvira nechando kuti kudzika mvura. Zaryblyayut reservoirs muchirimo, kana mvura kujairana 13-15 ° C. Panguva ino, furaya kurasikirwa iduku zvikuru pane mumatsutso kushanda juveniles. Uyezve, mashoko "chitubu" furaya pakarepo kutanga nokukurumidza kukura. Pasinei nokuti simba huru mumamiriro ezvinhu akadaro chakagadzirwa inosimbisa, mumwe mari zvokudya mugero Catfish anogamuchira nokuda yepanyama zvokudya mujinga mudhamu.

Semhuka zhinji, asati zviri kukonzera hasha kurwa wakarongwa vanhurume. Kazhinji kurwa izvi kuguma kunotevera, kukuvara kana kunyange rufu ichipererwa vavengi.

Pakangotanga hwemvura kuumbwa, uye mvura iri mvura kudziyirwa kune kutsvakwa tembiricha, mukono anosarudza muchivande nzvimbo, kazhinji pedyo nemhenderekedzo, uye anotanga kuvaka matendere vane kwazvo kucheneswa pasi sludge uye siyana ungwandangwanda.

Kutarisira masonry

The hadzi anoteya 2-3 mazai kugadzirirwa nezvigadziko akaturikidzana, rimwe nerimwe pakarepo impregnates makono kupedza yose muitiro kubva 4 kusvika 12 maawa. Masonry ndiye kwakavharwa nenyama inotungamirwa nemaziso chakafanana chipanje, zvinosanganisira rakajeka mazai orenji yakapoteredza, zvakasimba chokuita nomumwe. Mushure zviri kukonzera hono, sezvo baba wakanaka, iye anotanga kudzivirira mazai uye nehadzi anodzinga kure. By anotora rinokoshesa chaizvo muitiro, kwete chete inodzivirira batira anokosha, asi kubvira nguva nenguva vachidzungudza zvimbi yaro, nokusika kuwana mvura yakachena kuti kuita kuti pave paumbwe. Dzichiri mazai kwemaawa 120-122. mazai hatching vasati rima uye vanogona kuona hulking baleen tuvana uchiteverwa mukono ichiri rakada vachiongorora. Haachadi rinodederesa mazai uye zvinyoronyoro fanning vake zvimbi ake. Kana mazai dzikava mudumbu, mufambo wavo achiri muduku zvikuru, uye vanoramba vari dendere, dzikaumba gobvu masumbu kuchinja. Tuvana mumakore aya, masumbu vari akaronga musoro kuti nepakati uye miswe vari kugara zvitange. Nature akachenjera, uye izvozvo urongwa anobvumira tuvana rokusika womukati vortex chokubuda mvura, runoparara tsvina uye mazai akafa. With zera, vanova kushingaira, asi achiri inoitwa pedyo dendere. Mushure memazuva 2-3 ari mazana zviri kare akakwanisa kushambira kuti pemvura.
