I.Mmetụta anụ ahụ nke Ecdysterone
Ecdysterone bụ ihe steroid nke nwere ọtụtụ ọrụ physiological nke na-emekarị na metamorphosis na uto nke ụmụ ahụhụ na ụfọdụ crustaceans.Ọ nwere ike ịkwalite molt larval, mee ka ọganihu dịkwuo elu, ma melite ọnụego ndụ. Na mgbakwunye, ecdysterone nwekwara antibacterial, mgbochi mkpali, na mmetụta antioxidant, na-eme ka ọ nwee atụmanya ngwa ngwa na aquaculture.
II.Ngwa nke Ecdysterone na Aquaculture
Na-akwalite Uto na Mmụba Mmụba
Ecdysterone nwere ike ịkwalite uto nke anụ mmiri ma na-amụba mkpụrụ. N'ime nnyocha nke 斑节对虾(Penaeus monodon), otu nnwale ahụ nwere ecdysterone agbakwunyere mụbara na-eto eto karịa 30% ma e jiri ya tụnyere ndị na-ahụ maka njikwa (Smith et al., 2010). .N'ọmụmụ ihe ọzọ nke salmon Atlantic (Salmo salar), ịgbakwunye ecdysterone mụbara nkezi arọ azụ site na 20% (Jones et al.,2012).
Na-emewanye Nguzogide Ọrịa
Ecdysterone nwere antibacterial, mgbochi mkpali, na antioxidant mmetụta, nke nwere ike ime ka ọrịa na-eguzogide anụmanụ mmiri. Nnyocha egosiwo na ịgbakwụnye ecdysterone nwere ike budata ibelata ihe puru omume nke azụ na-ebute ọrịa (Johnson et al.,2013).
Imelite Ogo Mmiri
Ecdysteronenwere ike ịkwalite photosynthesis nke osisi mmiri ma melite ogo mmiri. N'ime nnyocha nke macroalgae, na-agbakwụnye ecdysterone mụbara photosynthesis site na 25% (Wang et al.,2011).
III.Economic Analysis
Ịgbakwunye ecdysterone nwere ike ibelata ụgwọ ọmụmụ, ịbawanye mkpụrụ, na uru akụ na ụba. N'ime nnyocha nke salmon Atlantic, ịgbakwunye ecdysterone mụbara nkezi arọ azụ site na 20% mgbe ị na-ebelata ụgwọ oriri na ụgwọ ọgwụ (Jones et al.,2012) .Nke a na-egosi. na ecdysterone nwere uru akụ na ụba dị ịrịba ama na aquaculture.
IV.Mkpebi na ntụzịaka nyocha n'ọdịnihu
Ecdysteronenwere ohere ngwa ngwa nke ukwuu na aquaculture.Ọ nwere ike ịkwalite uto nke anụmanụ mmiri, na-amụba mkpụrụ na nguzogide ọrịa, na-eme ka mmiri dị mma, na-ebelata ọnụ ahịa ọmụmụ. Otú ọ dị, a ka nwere nsogbu ụfọdụ na nyocha ugbu a na ntinye nke ecdysterone na aquaculture, dị otú ahụ dị ka ụkpụrụ dosing na-ekwekọghị ekwekọ na ụzọ eji eme ihe na-abụghị ọkọlọtọ. Ya mere, nyocha n'ọdịnihu kwesịrị ilekwasị anya n'ịkwalite ụkpụrụ eji eme ihe na usoro dosing nke ecdysterone iji chọpụtakwuo uru ngwa ngwa ya na aquaculture.
