Kuchuluka kwa mackerel kumatha kuyambira Epulo mpaka Juni, nthawi zambiri m'mphepete mwa Bulgaria ndi Romanian. Namsongole amakhala m'matanthowa am'madzi, nthawi zambiri pafupi ndi pamwamba, ndikupanga phokoso, ndikuwoneka bwino ndikuwunika ndi madzi, komanso kudziunjikira kwa nyama zomwe zimadya nsomba - dolphins, tuna, gulls. Kusunthika kwa mackerel a Black Sea kupita ku Nyanja ya Marmara kumayamba kutentha kwamadzi kukafika pa 10 ° C ndikutha mu Disembala - february, gawo laling'ono latsalira la nthawi yozizira kugombe la Turkey ndi Caucasus.
Mackerel amayamba kukhwima atakwanitsa zaka 2-5; mawonekedwe ake ndi mazira 350-500. Nditha kukhala ndi zaka 17-18.
Nsomba za Mackerel
Yankho la funso komwe mackerel amapezeka, muphunzirapo kanthu. Ili ndi dongosolo lamalingaliro, ndi gawo la banja la ma mackerel. Chosangalatsa ndichakuti, kuzungulira kwake sikugwirizana konse ndi pansi, motero kumawerengedwa kuti ndi nsomba ya pelagic.
Izi ndi nsomba zazikulu. Kutalika kwake kumafikira masentimita 64. Munthu wamba pafupifupi 30 cm. Thupi lomwe limapangidwa limafanana ndi chopondera, chomwe chimakutidwa ndi mamba yaying'ono. Ndikofunikira kudziwa kuti chikhodzodzo, chomwe chimayenera kukhala chamitundu yambiri ya nsomba, chimatha kupezeka kapena kusapezeka mu mackerel.

Ziphuphu zowonjezera zochulukirapo zimawathandiza kuti asalowe mumalowedwe ndi kuthamanga mwachangu. Nsomba nthawi zonse zimasunga ma jamb, nthawi zambiri zimaphatikizidwa ndi Seruines ya Peru. Mackerel ali ndi adani ambiri m'madzi ndi mlengalenga. Awa ndi anyani, ndi ma dolphin, ndi asodzi, ndi mikango yam'nyanja, ndipo ngakhale nsomba zazikulu.
Mackerel amamva bwino pokhapokha atentha madigiri 8 mpaka 20. Chifukwa chake, akuyenera kusamuka. Chaka chonse amakhala m'madzi otentha a Indian Ocean.
Nthawi yomweyo, ngakhale m'madzi akuTurkey samatentha kokwanira, chifukwa chake, kutentha kukangotsika, mackerel amasambira kumadera kwawo. Kuchokera ku Nyanja Yakuda, nsomba zimayandikira kumpoto kwa Europe. Nthawi zambiri pamakhala mafunde ofunda omwe amawapatsa moyo wabwino.

Kubala mackerel
Kutulutsa kwa Mackerel kumayamba mchaka chachiwiri cha moyo. Pambuyo pake zimadzetsa zaka zambiri chaka chilichonse. Kukalamba mu nsomba izi kumachitika kumapeto kwa zaka khumi zachiwiri.
Nsomba zazikulu zimamera mkatikati mwa masika, pomwe nsomba zazing'ono zimabereka kumapeto kwa June. Kubala kwawo kumagwira ntchito kwambiri, chifukwa nsomba ndizochulukirapo. Nthawi imodzi, amatha kusiya mazira mazana asanu pamtunda wa pafupifupi mamita mazana awiri. Danga la dzira lirilonse limakhala losaoneka ndi maso amunthu - limangokhala mamilimita okha. Mwa chilichonse chaiwo mumakhala dontho lamafuta, mothandizidwa ndi lomwe mwachangu amadya mukukula kwake konse.
Milandu ingati yomwe ingapangidwe mwachindunji zimatengera momwe malo abwino amakhalira. Pafupifupi, nthawi imeneyi imachokera masiku khumi mpaka milungu itatu. Mphutsi za mackerel pazokha ndizabwino, koma nthawi yomweyo zimakhala zolimbikitsa kwambiri. Udzu wodya nthawi zina mwa iwo umatha kudzutsidwa kotero kuti amatha kuthana ndi kudyana.
Mwachangu omwe adabadwa ndi ochepa kwambiri kukula kwake. Masentimita ochepa okha kutalika. Koma pofika m'dzinja amakula msanga. Kukula kwawo kumawonjezeka katatu. Pambuyo pa izi, kukula kwa achinyamata kwa mackerel kumayamba kuchepa.
Zinsinsi zakugwira mackerel
Mackerel anali wofunika nthawi zonse, motero, pafupifupi m'mbiri yonse ya anthu, nthawi zonse akhala akuchita chinthu chodziwedza kwambiri. Masiku ano, nsomba zosachepera 65,000 za nsomba zimagwidwa pachaka pagombe lakumadzulo.
Malo okhala ma mackerel ndi akulu kwambiri kotero kuti amachititsa kuti azitha kugwira mitundu yonse ya ngodya za dziko lapansi. Ogwira ntchito zausodzi amagwira ntchito ku Europe pagombe la Canary Islands, komanso ku Baltic, Black ndi Nyanja ya Marmara.

Asodzi achinyengo nthawi zambiri amagwira mackerel. Kwa odziwa migodi, izi sizabwino kwambiri. Ndiwothandiza kwambiri kugwira mackerel kuchokera m'boti kapena yacht. Mackerel ndi nsomba yadyera, kotero kukopeka ndikosavuta. Chifukwa cha izi, chilichonse chowala komanso chopatsa chidwi ndichabwino. Chifukwa chake, asodzi amapangira zibowo zamtundu uliwonse zazing'ono zazing'ono zazing'ono kapena siliva. Chachikulu ndichakuti chiwonekere bwino kuchokera kutali.
Nsomba zazing'ono zilizonse, nyama ya chipolopolo kapena nyambo yochita kupanga, yomwe ikugulitsidwa kwaulere, imayenera kugwiritsidwa ntchito ndi nyambo.
