Sayenzi hove - ichthyology

Chikamu ichi chinoongorora sayenzi zvemhuka hove: kwakatangira dzavo, mamiriro, dzinogarisana, kupa tsika, uye zvakawanda, kutaura navo. Rinotsanangura uye anoronga siyana upenyu hwemvura, hwavo kufamba uye kuwanda kubatsira mashoko enyu neKomisheni Fisheries uye hazvizivi kurimwa nomumwe kwemarudzi - zvose sayenzi rehove. Unofunga unodana chikamu ichi?

Nhoroondo yekare nyaya

Yokutanga Kuedza kutsvakurudza kuitwa munguva dzekare. Tinogona kutaura kuti China ndiye nesayenzi kuti vanodzidza hove, Chokwadi, mune wokugaya kunzwisisa inomuka rokutanga chemakore Kristu asati. Uye kuIndia - in 6 remakore BC. Wakamboona zvinyorwa, rakanga raitwa rondedzero mamwe marudzi, zvokurarama nazvo zvavo, hunhu dzinogarisana uye zvokudya.

Aristotle

The sainzi kuti inodzidza hove, yakazokudziridzwa (kwete yakazvimirira kuranga, asi somunhu chidimbu chacho) mu yakakurumbira basa yakakurumbira Aristotle uye mutsvakurudzi - "History of Animals" (4th remakore BC ..). Zvinofanira kucherechedzwa kuti mashoko ari zvomugungwa, zvange inorondedzerwa mubhuku, zvakanga saka inokosha iri vanenge ruzivo inokosha rehove kusvikira remakore rechi15. Zvino-sayenzi rehove vanovimba navo zvachose.

Independence uye ndakajeka

Kubva 15 kusvika 19 remakore, masayendisiti ose akasiyana inoti hoarded ruzivo vagere yamakungwa uye nyanza. Uye rechi19 pakupedzisira sayenzi rehove anova yakazvimirira chirango - ichthyology. Iye akamira basa vanhu nokugadzira chinoshingaira hove mumakore iwayo. anowana simba kutumbuka sayenzi hove mugungwa muzana remakore rechi20, somugumisiro kukura zvesainzi mukana kunyatsoongororazve kudzidza gungwa rakadzika kushandisa anyatsofukidzwa Ngarava dzepasi pemvura, submersibles, Akash uye chamunyurududu. Knowledge zvinokosha mberi nemashoko zvakananga Kuongorora zvomugungwa.

Sayenzi hove; zita uye chii zvidzidzo?

Saka, ichthyology ikozvino anomiririra mumwe zvikamu zvemhuka zvisikwa ane nomuzongoza - hove. Ari kudzidza maumbirwo dzavo, chikuru uye dzakabudirira mashandiro ari nhengo, dzinogarisana uye nzira youpenyu, kuparadzirwa, uye kubereka, shanduka kukura mhuka idzi gungwa, systematizing mhando uye subspecies.

Chimwe chikuru zvataurwa zvikuru zvibereko - kudzidza maitiro hove, zvichienderana nokuchinja zvakatipoteredza nekwavanogara. ezvinhu kwake kunoita kana anorodza zvaisazogona, ane kukanganisa zvokudya uye kubereka.

Chimwe vaizotibata mirayiridzo - kudzidza zvokudya. Kuvapo Its kana kusavapo, zvichienderana zvikonzero zvakasiyana-siyana (mumwe icho, Somuenzaniso, - upfumi basa vanhu) anosarudza kuti maitiro uye kunyange anosarudza kuvapo imwe mhando.

Maererano yaida kupatsanura, pane mhando anoverengeka hwemvura vertebrates vagari - ine utsinye. Benthophages Tidzidze zvipenyu vanogadzira nechepasi uye pasi mudhamu. Detritus - on akafa mapfupa uye utachiona. Mbeswa - zvakafanana, kureva hove. Herbivores - chirimwa zvokudya nemvura.

kushanda

Asi sayenzi rehove - hazvina kungova dzidziso. unyanzvi Vakawanda anobatsira zvakananga kushandiswa nokuda Fisheries: hove uye maberekero. Ivo zvinoshandiswa bhizimisi uye kugadzira nekuti kwezvakatipoteredza zvakafanotaurwa, kudzidza yamakungwa uye nyanza. Pashure pezvose, vazhinji redu yakafukidzwa nemvura, uye vose yenyika kwemarudzi emhuka vanobuda mumakungwa - nezvazvo uye musakanganwa! Zvezvisarudzo rokukurumidzira matambudziko kuti kugadziriswa kuburikidza ano ichthyology - Sangano zvakakodzera uye zvakaringana, asi playback pamusoro kunyatsodzidza Fisheries, vaikwanisa zvachose dambudziko mapuroteni zvitengeswa yose.
