Nathenje - ndi bizinezi?

Khumi zapitazi waona chidwi kukula mu nsomba. A zambiri mabizinesi ang'onoang'ono bwinobwino zikugwira kulima mitundu yosiyanasiyana ya nsomba m'mayiwewa anausiya. Mulinso mitundu ina ya mtengo wapatali ya nsomba kuti akhoza ayipanga chongopeka, pakati woyamba ubwenzi mumapezeka nsomba. nsomba, amene ali nyama zakudya ndi kukoma yowawitsa, komanso amati ndi wochezeka mankhwala zikufunika kwambiri pakati ogula. Choncho mumapezeka nsomba likupitirirabe wamba ndi kwambiri lipindulitsa ntchito.

Gulu la mumapezeka nsomba zovuta zifukwa zingapo ndipo conventionally izo lagawidwa mitundu iwiri: bulauni ndi utawaleza. Minda nsomba makamaka ikuchitika kuswana kwa utawaleza mumapezeka nsomba, zomwe ndi zotheka osati ozizira kuthamanga njirayo, koma m'madzi ofunda. Pakuti kukula kwa mitundu musati amafuna m'madera ambiri m'dziko. Chokha kuponyedwa yake ndi moyo ndi kukula - woyera ndi wodzazidwa ndi madzi mpweya, ndi momveka okwanira ndi kuwala.

Nathenje ali mbali kanukanu: makulitsidwe mazira ndiponso ana kukula amene akupezeka yekha pa zonse madzi kutentha. The momwe akadakwanitsira kutentha osiyanasiyana ndi 15 mpaka 18 madigiri. Pankhaniyi, pamaso pa chakudya zachilengedwe, mumapezeka nsomba limakula zonse: fingerlings kuti magalamu 30 kulemera, yearling anthu ndi magalamu 100-120, ndi zoyambira chaka awiri amatha kulemera magilamu 200.

Ndi kubereka mwachilungamo wabwino wa akazi (mazira 800 kwa 3000) mumapezeka nsomba n'chotheka kudzera mwa kukakamizidwa chonde kwa mazira, monga amatunga yokumba Nathenje si mzikiti. The ndondomeko ya insemination chiri motere: akazi kugonana okhwima mu chidebe lalikulu decanted caviar. Ndiye pakubwera kwa "milking" anthu olima wamwamuna. Chifukwa ndondomeko milt roe bwinobwino wothira njira youma kapena theka-youma. Ngati mazira wothira umuna kale sitimadzipereka mu madzi, njira imeneyi theka-youma umuna. Mu ndondomeko youma mankhwala insemination choyamba osokonezeka, ndi pamenepo pokha misa izi anawonjezera kuti madzi, kenako pansi mukubwadamuka.

Chongopeka ukala mazira anatumiza kwa hatchery lapansi. Kuwonjezera ng'ombe anali kumeneko ndi aswa mphutsi. Pamene mphutsi kukula mwachangu, iwo, monga alimi pa spawning, ndi kuziika. Komanso akuti ndi mumapezeka nsomba chofunika. A njira zina za kukula amadalira njira anasankha: mu akasinja kapena osayenera.

Ndi zotsatira zabwino zimatheka ndi njira kuyamba kulima izi chimake tima (zokolola ndi makilogalamu oposa 75 pa mita kiyubiki 1). Komabe, ntchito-tima kwambiri. Change madzi ndondomeko anapatsidwa amachitidwa pa mphindi 10-15, ndi mlingo wake otaya ndi pafupifupi 50 malita pa mphindi, pa mumapezeka nsomba 1 zikwi mutu. kachulukidwe wa kubzala chofunika mumapezeka nsomba ndi za 300-350 makope pa mita kiyubiki, ndi mwachangu 1 galamu - kuchokera 2000 kuti anthu 5000 pa mita cubed.

Njira ya chiwiri, mumapezeka nsomba osayenera mosavuta. Anthu anayikidwa mu nayiloni kapena mauna zitsulo imene kukula. Choncho, chovomerezeka kachulukidwe chofunika mumapezeka nsomba ayenera musalumphe makope 250 pa mita kiyubiki madzi. Kawiri nyengo osayenera mtundu wa ana.

Njira imeneyi amafuna chisamaliro chapadera ku mwambo wa malamulo ukhondo wa madzi, monga chiopsezo imfa ya nsomba katundu chifukwa cha kuwonongeka ake kuchuluka.

Mutu onse sayansi ndi ukhondo mfundo mumapezeka nsomba bwino analipira kumbuyo malonda. zokolola zake (. Per 1 mita kiyubiki) atakula mu amatunga pompo-pompo mwachangu ukufika 25-35, osayenera - 30-35, ndipo 50-75 m'madamu kilogalamu.
