I-Ecdysterone: Impumelelo eNtsha kuShishino lwe-Aquaculture

Ngenkqubela phambili eqhubekayo yobugcisa, ushishino lwasemanzini luyakhula kwaye luyanda.Nangona kunjalo, kule nkqubo, abalimi bajongene nemingeni emininzi, njengezifo rhoqo, ukuwohloka komgangatho wamanzi, kunye nokunyuka kweendleko. Ukusombulula ezi ngxaki, iindlela ezininzi ezintsha zokuzalanisa kunye nezongezo ziye zavela.Phakathi kwazo,i-ecdysterone,njengento yendalo yebhayoloji esebenzayo, itsale ingqwalasela ebanzi kushishino lwasemanzini lwasekhaya nangaphandle.

I.Iimpembelelo zePhysiological ye-Ecdysterone

I-Ecdysterone yinto ye-steroid enemisebenzi emininzi ye-physiological eyenza ngokukodwa kwi-metamorphosis kunye nokukhula kwezinambuzane kunye nezinye i-crustaceans.Inokukhuthaza i-larval molt, ikhulise ukukhula, kunye nokuphucula amazinga okuphila. iziphumo ze-antioxidant, ziyenza ibe namathemba osetyenziso olubanzi kwi-aquaculture.

II.Ukusetyenziswa kwe-Ecdysterone kwi-Aquaculture

Ukukhuthaza ukuKhula kunye noKwandisa izivuno

I-Ecdysterone inokukhuthaza kakhulu ukukhula kwezilwanyana zasemanzini kunye nokwandisa isivuno.Kuphononongo lwe斑节对虾 (Penaeus monodon), iqela lokulinga kunye ne-ecdysterone eyongeziweyo yonyuka ekukhuleni ngaphezu kwe-30% xa kuthelekiswa neqela lokulawula (uSmith et al., 2010) .Kwesinye isifundo se-salmon ye-Atlantic (i-Salmo salar), ukongeza i-ecdysterone yandisa ubunzima obuqhelekileyo beentlanzi nge-20% (Jones et al.,2012).

Ukuphucula Ukumelana Nezifo

I-Ecdysterone ine-antibacterial, anti-inflammatory, kunye ne-antioxidant effect, enokuphucula ukuxhathisa kwesifo sezilwanyana zasemanzini.Izifundo zibonise ukuba ukongeza i-ecdysterone kunokunciphisa kakhulu amathuba okuba intlanzi yosulelwe zizifo (uJohnson et al., 2013).

Ukuphucula uMgangatho waManzi

I-Ecdysteroneinokukhuthaza i-photosynthesis yezityalo zasemanzini kunye nokuphucula umgangatho wamanzi.Kuphando lwe-macroalgae, ukongeza i-ecdysterone yanda i-photosynthesis nge-25% (Wang et al., 2011).

III.Uhlalutyo lwezoqoqosho

Ukongeza i-ecdysterone inokunciphisa iindleko zokuzala, ukwandisa isivuno, kunye neenzuzo zoqoqosho.Kuphononongo lwe-salmon yase-Atlantic, ukongeza i-ecdysterone yandisa ubunzima obuqhelekileyo beentlanzi nge-20% ngelixa inciphisa iindleko zokutya kunye neendleko zamayeza (Jones et al.,2012) . ukuba i-ecdysterone ineenzuzo ezibalulekileyo zezoqoqosho kwi-aquaculture.

IV.Isiphelo kunye neSikhokelo soPhando lwexesha elizayo

I-Ecdysteroneinethuba elibanzi lokufaka isicelo kwi-aquaculture.Inokukhuthaza ukukhula kwezilwanyana zasemanzini, ukwandisa isivuno kunye nokumelana nezifo, ukuphucula umgangatho wamanzi, kunye nokunciphisa iindleko zokuzala.Nangona kunjalo, kusekho iingxaki kuphando lwangoku malunga nokusetyenziswa kwe-ecdysterone kwi-aquaculture, njengemigangatho yedosing engahambelaniyo kunye neendlela zokusetyenziswa ezingekho mgangathweni.Ngoko ke, uphando lwexesha elizayo kufuneka lugxininise ekuphuculeni imimiselo yokusetyenziswa kunye nemigangatho ye-dosing ye-ecdysterone ukuphonononga ngakumbi ixabiso layo lesicelo kwi-aquaculture.
