Ukuqotywa kweenkuniIbaluleke kakhulu kwiinkala zasemlanjeni. Ukuba iinkala zasemlanjeni azikhulwanga kakuhle, aziyi kukhula kakuhle. Ukuba kukho iinkala ezininzi ezitsala iinyawo, ziya kufa ngenxa yokungaphumeleli kokukhulwa.

Iqokobhe leenkabi zomlambo livela phi? Iqokobhe lalo livela kwiiseli ze-dermis epithelial eziphantsi kwalo, ezenziwe yi-epidermis ephezulu, i-epidermis yangaphandle kunye ne-epidermis yangaphakathi. Ingahlulwahlulwa ngokwe-shelling interval, i-early stage, i-late stage kunye ne-follow-stage.

Ixesha elifunekayo ukuze i-crab inyibilike liyahluka ngokobukhulu bayo. Okukhona incinci, kokukhona inyibilika ngokukhawuleza. Ngokwesiqhelo, kuthatha malunga nemizuzu eli-15-30 ukunyibilika kakuhle ngexesha, kwaye ngamanye amaxesha nemizuzu emi-3-5 ukunyibilika iqokobhe elidala. Ukuba inkqubo yokunyibilika ayiphumeleli, ixesha lokunyibilika liya kwanda, okanye life ngenxa yokungaphumeleli.

Inkala entsha imnyama ngombala, ithambile emzimbeni kwaye ipinki kwiinwele zeenyawo ze-claw. Iqhele ukubizwa ngokuba yi "soft shell crab". Ke ngoko, kwinkqubo yokunyibilika nasemva nje kokunyibilika, iinkala zomlambo azinawo amandla okumelana notshaba, eli lixesha eliyingozi ebomini bazo. Ngaphambi nasemva kokuba inkala yomlambo ilahle igobolondo layo elidala, kuyimfuneko ukwandisa umxholo we-calcium emzimbeni wamanzi. I-Potassium dicarboxylate kunye ne-calcium propionate ziyathululwa. I-30.1% ionic calcium ilula ukuba inkala yomlambo ifunxe kwaye iphucule uxinano lwe-calcium egazini.

 

Amanqaku aphambili olawulo ngexesha lokubola:

Ngexesha lokudubula,iqokobhe lenkalai-calcium kwaye ifunxa i-calcium kunye nee-trace elements. I-river crab iya kudla kakhulu, iqokelele izinto zamandla kunye nee-trace elements, kwaye ilungiselele izinto zokugquma.

• 1) Kwiintsuku ezimbini ngaphambi nasemva kokunyibilika ngakunye, fafaza i-150g / mu ye-active moltingi-calcium polyformate ngokuhlwa ukwandisa umxholo wee-ion ze-calcium emanzini. Umxholo we-ion ye-calcium ye-polyformate esebenzayo yi-≥ 30.1%. Inyibilika ngokupheleleyo emanzini kwaye kulula ukuyifunxa. Inokunyusa ubunzima bomzimba wamanzi, inyuse uxinzelelo lwe-calcium egazini le-river crab kwaye ikhuthaze iqokobhe eliqinileyo. Kwangaxeshanye, i-polyformate esebenzayo yongezwa kwisondlo rhoqo. I-asidi ye-formic yasimahla inokuthintela ukuzala kweebhaktheriya eziyingozi kwindlela yokugaya ukutya, iphucule ukufunxwa kunye nezinga lokusetyenziswa kwesondlo kwaye ikhuthaze ukondla.
• 2) Ngexesha lokunyibilika, inqanaba lamanzi kufuneka lihlale lizinzile, kwaye ngokubanzi akukho mfuneko yokutshintsha amanzi. Ukuphucula izinga lokusinda kokunyibilika kwe-river crab.
• 3) Indawo yokutya kunye nendawo yokubola kufuneka yahlulwe. Akuvumelekanga ngokungqongqo ukubeka isithiyelo kwindawo yokubola. Ukuba zimbalwa izityalo zasemanzini kwindawo yokubola, ezinyeemanziniizityalo mazifakwe zize zigcinwe zithule.
• 4) Xa utyelela ichibi kusasa, ukuba ufumana iinkala ezithambileyo, ungazithatha uzifake ebhakethini ukuze zigcinwe okwethutyana kangangeyure eli-1 ukuya kwezi-2. Emva kokuba iinkala zomlambo zifunxe amanzi aneleyo kwaye zikwazi ukunyuka ngokukhululekileyo, zingabuyiselwa echibini lokuqala.
