Ukufa Fish ebusika: iimpawu, izinto kunokwenzeka nothintelo

Kutshanje, abanini ezininzi izindlu lizwe kunye neendawo zokuhlala ezisezidolophini zithande ukuba banikele ingqalelo yabo amanzi ezivulekileyo, apho abanokuloba okanye nje ixesha elungileyo, abe wepikiniki elunxwemeni. Noko ke, kwentwasahlobo ungalinda isimanga zingambi kakhulu, ngokohlobo sentlanzi balahleke. Kuyinto ukuqonda ngakumbi, xa kukho ukufa ntlanzi.

Olu hlobo intlekele lwenzeka ubukhulu becala ebusika frosty, xa phantsi ngomaleko omkhulu womhlaba ze qhwa kancinci kodwa ekugqibeleni isantya iqala ukufa izilwanyana ezahlukeneyo - ooqongqothwane floaters, ezidla oohlabamanzi bokuhombisa, iintlobo eninzi ubomi emanzini. Amaxesha amaninzi ukufa intlanzi buqapheleke emva ice xa lwaseYurophu enobunzima izidumbu nakwisiqingatha wabola iintlanzi. Kodwa kukho ukunqongophala oksijini eziphilayo ekupheleni kukaFebruwari - ekuqaleni kuka March, njengoko zomongomoya onyibilikisiweyo sele wendele kwaye fresh ayikenziwa babhalise. Ubusika ngqwabalala, imiphumo ebuhlungu inokuba.

Uluntu izizathu ezininzi zokuba kukho ukufa intlanzi ebusika.

Oko ezinokuchaphazela kakubi ukukwazi ukuphila iintlanzi ebusika

• Awunamvume zaneleyo oxygen (okanye ngokupheleleyo ukungabikho) phakathi nomoya komhlaba phantsi ice iyabanda. Ukongeza, mpilo walidla iintlanzi nje kuphela, kodwa kobungxowa ubunzima zooplankton kwaye zondla, nto leyo eye efunde phezu ehlotyeni.
• Ukufa isixa esikhulu ulwelwe kubushushu ephantsi (nkqu izityalo eliseleyo ukuze aphuhlise ioksijini obaneleyo inkqubo yefotosinthesis kwiimeko ezibandayo kunye ukhanyiso elincinane).
• ungcoliseko lwamanzi avela inkunkuma mveliso okanye kamasipala, ilindle.
• Ubuthi kwindalo ngenxa ezihlala iintlanzi eseleyo phantsi inwebu ice iigesi eziyingozi (icarbon dioxide kunye monoxide okanye methane kunye emanzini hydrogen, njalo njalo). Zonke ezi izihloko nabo ukunciphisa izinga zomongomoya onyibilikisiweyo emanzini.

Uncedo kuphela imozulu abandayo yamanzi ukuba ngathi luyehla inkqubo nokuphefumla kunye ukubola. Kodwa ezingaphezu njengenkcitho kwichibi eseleyo mpilo credit ekugqibeleni kukhokelela kwizinto ezenzeka yokufa yeentlanzi.

Indlela ukugcina iintlanzi linyamalale ebusika

Nangona isibakala sokuba ukufa ubusika intlanzi sinobuzaza ngokwaneleyo, oko ingasombululwa iindlela kakuhle ezilula. Simply ukufaka empompeni kwi echibini, yaye isiguquli kunye umsebenzi spray umoya ugqibelele ukuba kwamachibi ezincinane. Nangona kunjalo, lo sisitshizi eqhelekileyo ayiboneleli ukujikeleza ezaneleyo, ukuba indawo ichibi ingaphezulu ubuncinane omnye-sisishumi hectare. Kulo mzekelo, imbonakalo yendawo ugcina zamornyh imimandla. Ngoko ke, enkulu abanini amadama evaliweyo kufuneka ufake amaqhoshana ezizodwa, ukuhamba-leyo oxygenate kuphela amanzi, kodwa ukwenza isiphumo ugeleza isitali, ekhu- yonke column amanzi.

Indlela ukuqinisekisa inqanaba neoksijini emanzini

Nabani na ofuna ukwazi amaqondo obushushu ngqo amanzi kunye nomgangatho wayo ioksijini Ukwanda, ukuze enze oko ngokusebenzisa termooksimetra. Kwakhona, le sixhobo iza kunceda ukuba wonge umbane, kuba Ukwanda ezaneleyo amanzi kufuneka uquke empompeni akayi kuvuka. Kubalulekile ukwazi ukuba ukufa iintlanzi iqala ekunciphiseni ioksijini kwinqanaba ukuya kumgangatho 6-7 mg / L (malunga-50 ukuya kuma-60% Ukwanda oqhelekileyo). Ezi ngcali bacebisa ukuthenga termooksimetr yodwa kunye uphenyo kunye intambo ngokwaneleyo elide (ubuncinane 3-5).

Indlela ukugcina neentlanzi Zamora, ukuba akukho empompeni

Abanini abaninzi abanamava bayazi amachibi - iqala xa ukusweleka intlanzi, kubalulekile ukuba kwenziwe umhlonyane, ngokwenjenjalo kuqinisekiswe ioksijini emanzini. Ukuze wenze oku ngamathuba ngokwaneleyo (ubuncinane ezimbini amaxesha ngeveki) ukusika okanye ukwaphula ngumkhenkce. Kwakhona kucetyiswa Ekungeneni zaye emkhenkceni iinyanda ngeengcongolo, nekalamo, straw. Kuyenzeka ukuba usebenzise pump (pump mas), ukumnyanzela amanzi phantsi kwe ice ubunzima. Le ndlela Kulula kakhulu ukuba abo bahlala kude ngokwaneleyo kwaye ayikwazi Ngokufuthi echibini.

Kufuneka kuqatshelwe, iingcali zisenamathandabuzo malunga indlela eyayithandwa ukugcina neentlanzi Zamora. Bathi ukuba ifuthe labo nonyango lwengqondo nje, ngokuba emngxunyeni kufuneka nje ukuba bagcine indlela yabemi kwamanzi ebusika (emanzini evaliweyo kwi emazantsi ajike ukuqwalasela izilwanyana kwabafileyo).

Ukongeza, ukuba lulutho "iindawo kungachetywa ntloko" kwi ngumkhenkce ukuze ufumane uluvo engalunganga ngenxa yokuba ekuqaleni ngexesha Zamora iintlanzi ngamandla emoyeni, yaye emva koko shwaka ethile, kuthiwa "umphefumlo". Enyanisweni, oko nje yafa okanye ufuna ziindawo ezikhuselekileyo. Kukho imbono ekhulayo Utyhila zentlako-hlaza nezasehlotyeni izilwanyana eziphilayo.

Oko kubalulekile ukuba sinikele ingqalelo ukuze aphephe Zamora

Kwakhona ukufa fish ebusika uqale ngenxa sisifo wesibeleko (hilodonellez, ich, trihodinioz) okanye esosulelayo (pseudomonosis). Nceda uqinisekise ukuba ubusika ekhuselekileyo exchange amanzi, ukuphucula zokuhlala iintlanzi. Ukongeza, kubalulekile ukuba sinikele ingqalelo kubunzulu ubuncinane avumelekile dami - kufuneka ungabi ngaphantsi kweemitha ezi-2. Inkqubo ichibi lime phambi ubusika (malunga ne-100 kg ngehektare nganye), kwaye wenze uhlalutyo kwilebhu umthombo wamanzi, ichibi ubonelelo. Iziphumo ezifunyenweyo kufuneka ifundwe ngenyameko kwaye kuthelekiswa nemigangatho emiselwe okuloba e imithombo yamanzi.

Ngaba kufuneka ukuba ondle iintlanzi ebusika

Kumaqondo obushushu asezantsi, ukufuduka intlanzi uthwala yendlala, ngoko akuyomfuneko ukondla kuyo. Ingakumbi ukuba ukutya akutyiwa ukuze cazulula emazantsi kwaye iyingozi. Kodwa ngaphandle trout - oko lubamba ngemali encinane ukutya lobushushu amanzi a ngasentla 2 ° C. Kuyanconywa ukuba aluse ukumodareyitha izihlandlo eziliqela ngeveki. Feed kufuneka bayeke isifundo kwisixando yokudla. Kungcono ukufaka feeder ezizodwa, apho ixesha intlanzi ukhetha amandla kunye nobungakanani ukutya.

Zamora uncedo zityhila ukuloba ice

Abalobi ntiyiso ungalahli ixesha naliphi na ixesha lonyaka - ke nezifuna umzimba ngamanzi obuhle, nkqu yokubanda. Kodwa lokuloba Zamora ezinokuchaphazela kakubi catch, ngoko ke ixesha ukuchonga nokuthintela nentlekele kuyo.

Umzekelo, uyakwazi ukuchaza Zamora kwezi zizathu zilandelayo:

• Ngokukhawuleza ukutshatyalaliswa kokuloba live.
• Mnyama line, nobhedu nangobhedu spinners.
• izinambuzane Dead phezu kwamanzi.
• Ukuyisa umfana bekhangela amanzi acocekileyo.
• Ukupheliswa ikhosi zentlanzi emithonjeni.

Phantsi kweemeko ezinjalo, ukuloba Kuza kubakho ukusilela. Ngaphezu koko, ukuloba ngexesha inxeba lalo esebenzayo ukuya amaqula uthathwa ngaphandle kwemvume.

Kubalulekile ukuba ukuphakuzela, sikhumbule ukuba ubusika Zamora yingxaki solvable. Ukuqinisekisa impumelelo iintlanzi ubusika ngenxa iindlela angentla kwaye ulandele imeko amanzi ichibi, ukunqanda izimanga ezingemnandi.
