Kukura kwemhuka dzeshrimp negakanje dzine hunhu hwekusvetuka, uye mushure mekunyunguduka ndipo panogona kuchinja kukura kwadzo.ecdysteroneKudyisa kunogona kuita shrimp uye magakanje molt nekukurumidza, kukurumidza kunyungudika, kuvandudza mwero wekupona uye kuwiriranisa kwekunyungudika, uye kuzadzisa chinangwa chekukura nekukurumidza.
1, Kuchera uye Kukura
Kukura kwe shrimp kunofanira kuvimba neshelling: chiyero chekukura kweSouth America white shrimp = shelling rate×Kukura uye kuwedzera kuwedzera.
Kana zvakatipoteredza zvakakodzera, shrimp fry inofanira kuvharwa kamwe chete pamaawa 30-40, uye makonye anorema 1-5 gramu anofanira kuvharwa kamwe chete mumazuva 4-6 oga oga. muhafu yekutanga yehusiku kutenderedza mazuva ekutanga neregumi nemashanu egore idzva remwedzi, pakati pechirimo nemafungu emvura; Kana mamiriro okunze akangoerekana achinja, zvinowanzoitika kusati kwaedza. Goko rinoomesa mumazuva 1-2.
Iyo yakajairwa dehulling frequency pakadzika munyu uye tembiricha yakakodzera inogona zvakare kuwedzera chiyero chekukura. Kudya kwe shrimp kunogona kuvharirwa kazhinji, izvo zvinopfupisa kutenderera kwekubereka kwekukura kwe shrimp.

4.Iyo ine kugadzikana kwakanyanya kwekushisa uye zvigadzirwa zvinobudirira hazvizoshanduki kana kurasikirwa panguva yegranulation process yeformula feed.
Tsanangudzo:Kugona kuita uye mashandisirwo ataurwa muchinyorwa chino zvese zvinobva mumabhuku anowanikwa pachena.
