izidlo zangokuhlwa
Iisardine ligama eliqokelelweyo lezinye iiherrings. Icala lomzimba lithe tyaba kwaye limhlophe njengesilivere. Iisardine ezindala zimalunga ne-26 cm ubude. Zisasazeke kakhulu kuMntla-ntshona wePasifiki ojikeleze iJapan kunye nonxweme lwePeninsula yaseKorea. I-docosahexaenoic acid (DHA) etyebileyo kwiisardine inokuphucula ingqondo kwaye iphucule inkumbulo, ngoko ke iisardine zikwabizwa ngokuba "kukutya okukrelekrele".
IiSardines ziintlanzi ezihlala emanzini afudumeleyo emanzini aselunxwemeni kwaye azifumaneki rhoqo kwiilwandle ezivulekileyo nakwiilwandle. Zidada ngokukhawuleza kwaye zihlala kwindawo ephakathi ephezulu, kodwa ekwindla nasebusika xa ubushushu bamanzi angaphezulu buphantsi, zihlala kwiindawo ezinzulu zolwandle. Ubushushu obuphezulu beesardines ezininzi bumalunga nama-20-30℃, kwaye zimbalwa iintlobo ezinobushushu obuphantsi. Umzekelo, ubushushu obuphezulu beesardines zaseMpuma Ekude yi-8-19℃. Iisardines zitya kakhulu iplankton, eyahluka ngokweentlobo, indawo yolwandle kunye nexesha lonyaka, njengeentlanzi ezindala kunye neentlanzi ezincinci. Umzekelo, i-golden sardine endala itya kakhulu ii-planktonic crustaceans (kuquka ii-copepods, ii-brachyuridae, ii-amphipods kunye nee-mysids), kwaye itya nee-diatoms. Ukongeza ekutyeni ii-planktonic crustaceans, iintsha zitya nee-diatoms kunye neeDinoflagellates. Iisardines zegolide ngokubanzi azifuduki umgama omde. Ekwindla nasebusika, iintlanzi ezindala zihlala emanzini anzulu kwiimitha ezingama-70 ukuya kuma-80 ukusuka apho. Entwasahlobo, ubushushu bamanzi aselunxwemeni buyanyuka kwaye iintlanzi ziyafuduka kufutshane nonxweme ukuze zikwazi ukuzala. Iimbungu kunye neentshontsho zikhula kwisithiyo saselunxwemeni kwaye kancinci kancinci ziyahamba ziye emantla kunye nomsinga ofudumeleyo woLwandle lwaseMzantsi China ehlotyeni. Ubushushu bamanzi angaphezulu buyehla ekwindla kwaye emva koko ziya emazantsi. Emva kuka-Okthobha, xa umzimba wentlanzi ukhule waya ngaphezulu kwe-150 mm, ngenxa yokwehla kobushushu bamanzi aselunxwemeni, kancinci kancinci iya kwindawo enzulu yolwandle.
Ixabiso lesondlo leesardine
1. Iisardine zityebile kwiproteni, elona nani liphezulu le-iron kwiintlanzi. Zityebile nakwi-EPA, enokuthintela izifo ezifana ne-myocardial infarction, kunye nezinye ii-unsaturated fatty acids. Kukutya okunempilo okufanelekileyo. I-nucleic acid, isixa esikhulu sevithamini A kunye ne-calcium equlethwe kwisardine inokuphucula inkumbulo.
2. Iisardine ziqulathe i-fatty acid ene-long-chain ene-double bonds ezi-5, ezinokuthintela i-thrombosis kwaye zibe nefuthe elikhethekileyo kunyango lwesifo sentliziyo.
3. Iisardine zityebile kwi-vitamin B kunye ne-marine repair essence. I-Vitamin B inokunceda ekukhuleni kwezipikili, iinwele kunye nolusu. Ingenza iinwele zibe mnyama, zikhule ngokukhawuleza, kwaye zenze ulusu lubonakale lucocekile kwaye lulungelelene ngakumbi.
Ngamafutshane, iisardine bezisoloko zithandwa luluntu ngenxa yesondlo sazo kunye nencasa yazo entle.
Ukuze uluntu lwamkele ngconoiisardine, inkampani ikwaphuhlise iintlobo ngeentlobo zezinongo, inethemba lokwenza oku “ukutya okukrelekrele"yanelisa uluntu."
