chakudya chamadzulo
Ma sardine ndi dzina la nyama zina zotchedwa herrings. Mbali ya thupi lake ndi yosalala komanso yoyera ngati siliva. Ma sardine akuluakulu ndi otalika pafupifupi 26 cm. Amapezeka makamaka kumpoto chakumadzulo kwa Pacific kuzungulira Japan ndi gombe la Korea Peninsula. Docosahexaenoic acid (DHA) yochuluka mu sardine imatha kukonza nzeru ndikuwonjezera kukumbukira, kotero sardine amatchedwanso "chakudya chanzeru".

Nsomba za sardine ndi nsomba za m'madzi ofunda m'madzi a m'mphepete mwa nyanja ndipo nthawi zambiri sizipezeka m'nyanja ndi m'nyanja. Amasambira mwachangu ndipo nthawi zambiri amakhala m'chigawo chapakati chapamwamba, koma nthawi yophukira ndi yozizira pamene kutentha kwa madzi pamwamba kumakhala kochepa, amakhala m'madera akuya a nyanja. Kutentha kwabwino kwa sardine ambiri ndi pafupifupi 20-30℃, ndipo mitundu yochepa yokha ndi yomwe imakhala ndi kutentha kotsika. Mwachitsanzo, kutentha kwabwino kwa sardine za ku Far Eastern ndi 8-19℃. Sardine makamaka amadya plankton, zomwe zimasiyana malinga ndi mtundu, dera la nyanja ndi nyengo, monganso nsomba zazikulu ndi nsomba zazing'ono. Mwachitsanzo, sardine wamkulu wagolide amadya makamaka planktonic crustaceans (kuphatikizapo copepods, brachyuridae, amphipods ndi mysids), komanso amadya diatoms. Kuwonjezera pa kudya planktonic crustaceans, achichepere amadyanso diatoms ndi Dinoflagellates. Golden sardines nthawi zambiri samayenda mtunda wautali. Mu nthawi yophukira ndi yozizira, nsomba zazikulu zimakhala m'madzi akuya mamita 70 mpaka 80 kutali. Mu masika, kutentha kwa madzi a m'mphepete mwa nyanja kumakwera ndipo nsomba zimasamukira pafupi ndi gombe kuti zibereke. Mphutsi ndi ana amakula pa nyambo ya m'mphepete mwa nyanja ndipo pang'onopang'ono amasamukira kumpoto ndi mafunde otentha a Nyanja ya South China nthawi yachilimwe. Kutentha kwa madzi pamwamba kumatsika nthawi yophukira kenako kumasamukira kum'mwera. Pambuyo pa Okutobala, pamene thupi la nsomba lakula kufika pa 150 mm, chifukwa cha kuchepa kwa kutentha kwa madzi a m'mphepete mwa nyanja, pang'onopang'ono limasamukira kudera lakuya la nyanja.

Zakudya zabwino za sardine

1. Ma sardine ali ndi mapuloteni ambiri, omwe ndi chitsulo chambiri mu nsomba. Alinso ndi EPA yambiri, yomwe imatha kupewa matenda monga matenda a mtima, ndi mafuta ena osakhuta.

3. Ma sardine ali ndi vitamini B wambiri komanso mankhwala okonzanso zinthu za m'madzi. Vitamini B ingathandize kukula kwa misomali, tsitsi ndi khungu. Ingapangitse tsitsi kukhala lakuda, kukula mofulumira, komanso imapangitsa khungu kuwoneka loyera komanso lofanana.

Mwachidule, sardine nthawi zonse zimakondedwa ndi anthu chifukwa cha zakudya zake zabwino komanso kukoma kwake kwabwino.

Kuti anthu onse avomereze bwinosadini, kampaniyo yapanganso mitundu yosiyanasiyana ya zokometsera izi, ikuyembekeza kupanga izi "chakudya chanzeru"khutiritsani anthu onse."
